Set bitstream filters for matching streams. @var{bitstream_filters} is
a comma-separated list of bitstream filters. Use the @code{-bsfs} option
to get the list of bitstream filters.
Apply bitstream filters to matching streams.
@var{bitstream_filters} is a comma-separated list of bitstream filter
specifications. The specified bitstream filters are applied to coded packets in
the order they are written in. Each bitstream filter specification is of the
form
@example
@var{filter}[=@var{optname0}=@var{optval0}:@var{optname1}=@var{optval1}:...]
@end example
Any of the ',=:' characters that are to be a part of an option value need to be
escaped with a backslash.
Use the @code{-bsfs} option to get the list of bitstream filters.
@example
ffmpeg -i h264.mp4 -c:v copy -bsf:v h264_mp4toannexb -an out.h264
