The 'B' postfix multiplies the value for 8, and can be -appended after another postfix or used alone.

To see the list of available AVOptions, use the -@option{-help} option. They are separated into two categories: -@table @option -@item generic -These options can be set for any container, codec or device. Generic options are -listed under AVFormatContext options for containers/devices and under -AVCodecContext options for codecs. -@item private -These options are specific to the given container, device or codec. Private -options are listed under their corresponding containers/devices/codecs. -@end table - -For example to write an ID3v2.3 header instead of a default ID3v2.4 to -an MP3 file, use the @option{id3v2_version} private option of the MP3 -muxer: -@example -ffmpeg -i input.flac -id3v2_version 3 out.mp3 -@end example - -You can precisely specify which stream(s) should the codec AVOption apply to by -appending a stream specifier of the form -@option{[:@var{stream_type}][:@var{stream_index}]} to the option name. -@var{stream_type} is 'v' for video, 'a' for audio and 's' for subtitle streams. -@var{stream_index} is a global stream index when @var{stream_type} isn't -given, otherwise it counts streams of the given type only. As always, the index -is zero-based. For example -@example --foo -- applies to all applicable streams --foo:v -- applies to all video streams --foo:a:2 -- applies to the third audio stream --foo:0 -- applies to the first stream -@end example - -Note -nooption syntax cannot be used for boolean AVOptions, use -option -0/-option 1. - -Note2 old undocumented way of specifying per-stream AVOptions by prepending -v/a/s to the options name is now obsolete and will be removed soon. |
