In addition each codec may support so-called private options, which are specific for a given codec. Sometimes, a global option may only affect a specific kind of codec, and may be nonsensical or ignored by another, so you need to be aware of the meaning of the specified options. Also some options are meant only for decoding or encoding.
In 1-pass mode, bitrate tolerance specifies how far ratecontrol is willing to deviate from the target average bitrate value. Lowering tolerance too much has an adverse effect on quality. Only write platform-, build- and time-independent data. This ensures that file and data checksums are reproducible and match between platforms. Its primary use is for regression testing. It is the fundamental unit of time in seconds in terms of which frame timestamps are represented.
Set cutoff bandwidth. Supported only by selected encoders, see their respective documentation sections. It is set by some decoders to indicate constant frame size.
Set video quantizer scale compression VBR. It is used as a constant in the ratecontrol equation. Must be an integer between -1 and If a value of -1 is used, it will choose an automatic value depending on the encoder. Note: experimental decoders can pose a security risk, do not use this for decoding untrusted input. This is useful if you want to analyze the content of a video and thus want everything to be decoded no matter what.
This option will not result in a video that is pleasing to watch in case of errors. Most useful in setting up a CBR encode. It is of little use elsewise. At present, those are H. Supported at present by AV1 decoders. Set the number of threads to be used, in case the selected codec implementation supports multi-threading.
Set encoder codec profile. Encoder specific profiles are documented in the relevant encoder documentation. Possible values:.
Set to 1 to disable processing alpha transparency. Default is 0. Separator used to separate the fields printed on the command line about the Stream parameters. For example, to separate the fields with newlines and indentation:.
Maximum number of pixels per image. This value can be used to avoid out of memory failures due to large images. Enable cropping if cropping parameters are multiples of the required alignment for the left and top parameters. If the alignment is not met the cropping will be partially applied to maintain alignment.
Default is 1 enabled. When you configure your FFmpeg build, all the supported native decoders are enabled by default. Decoders requiring an external library must be enabled manually via the corresponding --enable-lib option.
You can list all available decoders using the configure option --list-decoders. Requires the presence of the libdav1d headers and library during configuration. You need to explicitly configure the build with --enable-libdav1d. Set amount of frame threads to use during decoding. The default value is 0 autodetect. Use the global option threads instead.
Set amount of tile threads to use during decoding. Apply film grain to the decoded video if present in the bitstream. Defaults to the internal default of the library. This option is deprecated and will be removed in the future. Select an operating point of a scalable AV1 bitstream 0 - Requires the presence of the libuavs3d headers and library during configuration. You need to explicitly configure the build with --enable-libuavs3d. Dynamic Range Scale Factor. The factor to apply to dynamic range values from the AC-3 stream.
This factor is applied exponentially. The default value is 1. There are 3 notable scale factor ranges:. DRC enabled. Applies a fraction of the stream DRC value.
Audio reproduction is between full range and full compression. Loud sounds are fully compressed. Soft sounds are enhanced. The lavc FLAC encoder used to produce buggy streams with high lpc values like the default value. This decoder generates wave patterns according to predefined sequences. Its use is purely internal and the format of the data it accepts is not publicly documented. Requires the presence of the libcelt headers and library during configuration.
You need to explicitly configure the build with --enable-libcelt. Requires the presence of the libgsm headers and library during configuration. You need to explicitly configure the build with --enable-libgsm. Requires the presence of the libilbc headers and library during configuration.
You need to explicitly configure the build with --enable-libilbc. Using it requires the presence of the libopencore-amrnb headers and library during configuration. You need to explicitly configure the build with --enable-libopencore-amrnb. Using it requires the presence of the libopencore-amrwb headers and library during configuration.
You need to explicitly configure the build with --enable-libopencore-amrwb. Requires the presence of the libopus headers and library during configuration. You need to explicitly configure the build with --enable-libopus. Sets the base path for the libaribb24 library. This is utilized for reading of configuration files for custom unicode conversions , and for dumping of non-text symbols as images under that location. This codec decodes the bitmap subtitles used in DVDs; the same subtitles can also be found in VobSub file pairs and in some Matroska files.
Specify the global palette used by the bitmaps. When stored in VobSub, the palette is normally specified in the index file; in Matroska, the palette is stored in the codec extra-data in the same format as in VobSub. The format for this option is a string containing 16 bits hexadecimal numbers without 0x prefix separated by commas, for example 0d00ee, eed, , eaeaea, 0ce60b, ec14ed, ebff0b, 0da, 7b7b7b, d1d1d1, 7b2a0e, 0dc, 0fb, cf0dec, cfa80c, 7cb.
Only decode subtitle entries marked as forced. Some titles have forced and non-forced subtitles in the same track. Setting this flag to 1 will only keep the forced subtitles.
Default value is 0. Requires the presence of the libzvbi headers and library during configuration. You need to explicitly configure the build with --enable-libzvbi. List of teletext page numbers to decode. Pages that do not match the specified list are dropped.
Set default character set used for decoding, a value between 0 and 87 see ETS , Section 15, Table Default value is -1, which does not override the libzvbi default. This option is needed for some legacy level 1.
The default format, you should use this for teletext pages, because certain graphics and colors cannot be expressed in simple text or even ASS. Formatted ASS output, subtitle pages and teletext pages are returned in different styles, subtitle pages are stripped down to text, but an effort is made to keep the text alignment and the formatting.
Chops leading and trailing spaces and removes empty lines from the generated text. This option is useful for teletext based subtitles where empty spaces may be present at the start or at the end of the lines or empty lines may be present between the subtitle lines because of double-sized teletext characters. Default value is 1. Sets the display duration of the decoded teletext pages or subtitles in milliseconds.
Default value is -1 which means infinity or until the next subtitle event comes. Force transparent background of the generated teletext bitmaps. Default value is 0 which means an opaque background. Sets the opacity of the teletext background.
When you configure your FFmpeg build, all the supported native encoders are enabled by default. Encoders requiring an external library must be enabled manually via the corresponding --enable-lib option. You can list all available encoders using the configure option --list-encoders. Setting this automatically activates constant bit rate CBR mode. If this option is unspecified it is set to kbps. Set quality for variable bit rate VBR mode.
This option is valid only using the ffmpeg command-line tool. Set cutoff frequency. If unspecified will allow the encoder to dynamically adjust the cutoff to improve clarity on low bitrates. This method first sets quantizers depending on band thresholds and then tries to find an optimal combination by adding or subtracting a specific value from all quantizers and adjusting some individual quantizer a little. This is an experimental coder which currently produces a lower quality, is more unstable and is slower than the default twoloop coder but has potential.
Not currently recommended. Worse with low bitrates less than 64kbps , but is better and much faster at higher bitrates. Can be forced for all bands using the value "enable", which is mainly useful for debugging or disabled using "disable".
Sets intensity stereo coding tool usage. Can be disabled for debugging by setting the value to "disable". Uses perceptual noise substitution to replace low entropy high frequency bands with imperceptible white noise during the decoding process. Enables the use of a multitap FIR filter which spans through the high frequency bands to hide quantization noise during the encoding process and is reverted by the decoder. As well as decreasing unpleasant artifacts in the high range this also reduces the entropy in the high bands and allows for more bits to be used by the mid-low bands.
Enables the use of the long term prediction extension which increases coding efficiency in very low bandwidth situations such as encoding of voice or solo piano music by extending constant harmonic peaks in bands throughout frames.
Use in conjunction with -ar to decrease the samplerate. Enables the use of a more traditional style of prediction where the spectral coefficients transmitted are replaced by the difference of the current coefficients minus the previous "predicted" coefficients. In theory and sometimes in practice this can improve quality for low to mid bitrate audio. The default, AAC "Low-complexity" profile. Is the most compatible and produces decent quality. Introduced in MPEG4.
Introduced in MPEG2. This does not mean that one is always faster, just that one or the other may be better suited to a particular system. The AC-3 metadata options are used to set parameters that describe the audio, but in most cases do not affect the audio encoding itself.
Some of the options do directly affect or influence the decoding and playback of the resulting bitstream, while others are just for informational purposes. A few of the options will add bits to the output stream that could otherwise be used for audio data, and will thus affect the quality of the output. Those will be indicated accordingly with a note in the option list below. Allow Per-Frame Metadata. Specifies if the encoder should check for changing metadata for each frame. Center Mix Level.
The amount of gain the decoder should apply to the center channel when downmixing to stereo. This field will only be written to the bitstream if a center channel is present. The value is specified as a scale factor. There are 3 valid values:. Surround Mix Level. The amount of gain the decoder should apply to the surround channel s when downmixing to stereo. This field will only be written to the bitstream if one or more surround channels are present.
Audio Production Information is optional information describing the mixing environment. Either none or both of the fields are written to the bitstream. Mixing Level. Specifies peak sound pressure level SPL in the production environment when the mix was mastered. Valid values are 80 to , or -1 for unknown or not indicated. The default value is -1, but that value cannot be used if the Audio Production Information is written to the bitstream.
Room Type. Describes the equalization used during the final mixing session at the studio or on the dubbing stage. A large room is a dubbing stage with the industry standard X-curve equalization; a small room has flat equalization. Dialogue Normalization. This parameter determines a level shift during audio reproduction that sets the average volume of the dialogue to a preset level.
The goal is to match volume level between program sources. A value of dB will result in no volume level change, relative to the source volume, during audio reproduction.
Valid values are whole numbers in the range to -1, with being the default. Dolby Surround Mode. Specifies whether the stereo signal uses Dolby Surround Pro Logic. This field will only be written to the bitstream if the audio stream is stereo. Original Bit Stream Indicator. Specifies whether this audio is from the original source and not a copy.
It is grouped into 2 parts. If any one parameter in a group is specified, all values in that group will be written to the bitstream. Default values are used for those that are written but have not been specified. Preferred Stereo Downmix Mode. Dolby Surround EX Mode. Indicates whether the stream uses Dolby Surround EX 7. Dolby Headphone Mode. Indicates whether the stream uses Dolby Headphone encoding multi-channel matrixed to 2.
Stereo Rematrixing. This option is enabled by default, and it is highly recommended that it be left as enabled except for testing purposes.
Set lowpass cutoff frequency. If unspecified, the encoder selects a default determined by various other encoding parameters. These options are only valid for the floating-point encoder and do not exist for the fixed-point encoder due to the corresponding features not being implemented in fixed-point.
The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies. This option is enabled by default for the floating-point encoder and should generally be left as enabled except for testing purposes or to increase encoding speed.
Coupling Start Band. Sets the channel coupling start band, from 1 to If a value higher than the bandwidth is used, it will be reduced to 1 less than the coupling end band. If auto is used, the start band will be determined by the encoder based on the bit rate, sample rate, and channel layout. This option has no effect if channel coupling is disabled. Sets the compression level, which chooses defaults for many other options if they are not set explicitly. Valid values are from 0 to 12, 5 is the default.
Chooses if rice parameters are calculated exactly or approximately. Multi Dimensional Quantization. If set to 1 then a 2nd stage LPC algorithm is applied after the first stage to finetune the coefficients. This is quite slow and slightly improves compression. This is a native FFmpeg encoder for the Opus format. Currently its in development and only implements the CELT part of the codec. Its quality is usually worse and at best is equal to the libopus encoder.
If unspecified it uses the number of channels and the layout to make a good guess. Sets the maximum delay in milliseconds. Lower delays than 20ms will very quickly decrease quality. Requires the presence of the libfdk-aac headers and library during configuration. You need to explicitly configure the build with --enable-libfdk-aac.
The library is also incompatible with GPL, so if you allow the use of GPL, you should configure with --enable-gpl --enable-nonfree --enable-libfdk-aac. If the bitrate is not explicitly specified, it is automatically set to a suitable value depending on the selected profile.
Note that VBR is implicitly enabled when the vbr value is positive. If not specified or explicitly set to 0 it will use a value automatically computed by the library. Enable afterburner feature if set to 1, disabled if set to 0. This improves the quality but also the required processing power.
Set VBR mode, from 1 to 5. Requires the presence of the libmp3lame headers and library during configuration. You need to explicitly configure the build with --enable-libmp3lame. See libshine for a fixed-point MP3 encoder, although with a lower quality. The following options are supported by the libmp3lame wrapper. The lame -equivalent of the options are listed in parentheses. Set constant quality setting for VBR.
Set algorithm quality. Valid arguments are integers in the range, with 0 meaning highest quality but slowest, and 9 meaning fastest while producing the worst quality. Enable use of bit reservoir when set to 1. LAME has this enabled by default, but can be overridden by use --nores option.
Enable the encoder to use ABR when set to 1. The lame --abr sets the target bitrate, while this options only tells FFmpeg to use ABR still relies on b to set bitrate.
Requires the presence of the libopencore-amrnb headers and library during configuration. You need to explicitly configure the build with --enable-libopencore-amrnb --enable-version3. This is a mono-only encoder.
Set bitrate in bits per second. Only the following bitrates are supported, otherwise libavcodec will round to the nearest valid bitrate. Allow discontinuous transmission generate comfort noise when set to 1. The default value is 0 disabled. Most libopus options are modelled after the opusenc utility from opus-tools.
The following is an option mapping chart describing options supported by the libopus wrapper, and their opusenc -equivalent in parentheses. Set VBR mode.
The FFmpeg vbr option has the following valid arguments, with the opusenc equivalent options in parentheses:. Set encoding algorithm complexity. Valid options are integers in the range. Set maximum frame size, or duration of a frame in milliseconds. The argument must be exactly the following: 2. Smaller frame sizes achieve lower latency but less quality at a given bitrate. Sizes greater than 20ms are only interesting at fairly low bitrates. The default is 20ms.
Enable inband forward error correction. Default is disabled. Set cutoff bandwidth in Hz. The argument must be exactly one of the following: , , , , or , corresponding to narrowband, mediumband, wideband, super wideband, and fullband respectively. The default is 0 cutoff disabled. Set channel mapping family to be used by the encoder. The default value of -1 uses mapping family 0 for mono and stereo inputs, and mapping family 1 otherwise.
The default also disables the surround masking and LFE bandwidth optimzations in libopus, and requires that the input contains 8 channels or fewer. Other values include 0 for mono and stereo, 1 for surround sound with masking and LFE bandwidth optimizations, and for independent streams with an unspecified channel layout. If set to 0, disables the use of phase inversion for intensity stereo, improving the quality of mono downmixes, but slightly reducing normal stereo quality. The default is 1 phase inversion enabled.
Shine is a fixed-point MP3 encoder. It has a far better performance on platforms without an FPU, e. However, as it is more targeted on performance than quality, it is not on par with LAME and other production-grade encoders quality-wise. Right-click on the Modern Warfare exe and set priority to Normal. It get stuck there. I can still access menu's and the game isn't frozen entirely. The reason why Call of Duty: Warzone gets stuck on the loading screen has yet to be tracked down and neither publisher Activision nor developer Infinity Ward has come forth with a potential fix.
It says launching, then game is running. You can check all the fixes for April 30 update down below. Uninstalled the game along with all extra content, hard reset the Xbox One, unplugged it for an hour, reinstalled the game and extra content. Cities skylines loading stuck. You can also turn it off and check once. To fix the Anon name bug error in Modern Warfare, follow the four steps below. This is tied to the game being unable to fetch online profiles for players.
Open Steam, load game. Restart the Game; 1. This means the update usually failed. Basically, NAT Type is the status of your internet connection. Now, scroll down to where it says The loading screen appeared, and moody music resonated. It shouldn't start because it isn't loading via Steam, but it will set the game to Windows 7 mode.
Step 5: Select Change priority if requested for permission to make changes. I join the server and it gets stuck on the loading screen. And now when it works just set it at half way. This is the first thing you should try when you have a black screen issue on Call of Duty Modern Warfare.
Players are unable to load into the game, and are stuck waiting for the update to either finish on its own or not able to play. Modern Warfare walk. Set your Film Grain to a value of 1. Some of you might be experiencing issues connecting to online services. Hi guys, I have this small problem I deal withI downloaded a the War3zdude external box esp a few months ago and it worked fine. The server isn't full. BielFPs 2 Nov.
Quote According to a Proton developer if you have an older Kernel fsync should be automatically disabled so if you want to use it you need to update. One of the reasons why I personally don't like to use "stable" distros myself Quote FEAR 3 I wish there was a way to force this game to use steamcloud, every time I want to play as Fettel I need to first finish the game as Pointman.
Also according to the github ticket of Just Cause 2 you need proton experimental bleeding edge branch I've tried running it in Proton for months, to no avail.
I can finally unlock the map-type achievements, that Aspyr never fixed on Linux Last edited by pb on 2 November at pm UTC.
SirBubbles 2 Nov. Well, I'm hoping that one day, Space Marine might just work. I loved smashing Ork face, but cracking it and running it the old-fashioned way seemed a hassle. Purple Library Guy 2 Nov. Why not? Apparently just 'cause. If I pause and resume the download, the download will start showing less than To do this, go back to Battle.
Update 1. If you own a copy of Modern Warfare, you will need to download the new update being released on March Here's what you need to know. Can I play Warzone on a console using a mouse and keyboard? In graphics options, try lowering the settings to Medium and set your render scale at 80 per cent. Learn more about how Google Update works. The micro usb cord isn't universal. If you meet all those minimum requirements but keep having crashes, the next step is to follow the standard troubleshooting measure of checking for corrupted files.
If it's the error with a game from PS Store, go to [Library] and select the application to download the file. However there are different ways to do this. Here at CMG, you can also play games for money while blasting your way through competitive online gaming tournaments. You can check the complete patch notes for the update down below.
Developers have announced a fix is on the way. Players should check their online connection and the server status for Battle. Delete old files and game data from your PlayStation 4. Update or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
And if you don't find the details you are looking for please use the Question and Answer section to ask other players for more help. The next time you start Minecraft, the new update will install automatically. Players who are having large download problems are having installs of 80 or GB due to the game fully reinstalling itself.
The communication between the client connection player and the server is not solid, which could mean a variety of things. But more than most players are reporting that they are stuck in an infinite loop with a 'checking for update' error message.
Have another one on hand. On the PS4, the download size is 9. Here we will discuss about how to fix PS4 Safe Mode loop issue. Every important in-game event is tracked and systemized for future analysis.
It typically means users cannot log in or connect to Modern Warfare or Warzone. Is everything else in good working order? If your PlayStation 4 is up to date, try the following troubleshooting tips: Check your game disc for abrasions, scratches, or dust. The game now offers over 50 Operators to choose from, but now some players have had that choice taken away from them. There are also some optimizations and bug fixes. For each game, you can select the saved data to copy.
I have an older PS3 It was a gift, I don't know the hard drive size.
