bsrw

Compressed bitstream rewriter

Register name used to load filter: bsrw
This filter is not checked during graph resolution and needs explicit loading.
Filters of this class can connect to each-other.

This filter rewrites some metadata of various bitstream formats.
The filter can currently modify the following properties in video bitstreams:
- MPEG-4 Visual:
- sample aspect ratio
- profile and level
- AVC|H264, HEVC and VVC:
- sample aspect ratio
- profile, level, profile compatibility
- video format, video fullrange
- color primaries, transfer characteristics and matrix coefficients (or remove all info)
- ProRes:
- sample aspect ratio
- color primaries, transfer characteristics and matrix coefficients

Values are by default initialized to -1, implying to keep the related info (present or not) in the bitstream.
A sar value of 0/0 will remove sample aspect ratio info from bitstream if possible.

The filter can currently modify the following properties in the stream configuration but not in the bitstream:
HEVC: profile IDC, profile space, general compatibility flags
VVC: profile IDC, general profile and level indication

The filter will work in passthrough mode for all other codecs and media types.
