#8050 new enhancement
Active Format Description missing (MPEG-2 and H.264)
|Reported by:||Anton Torp||Owned by:|
|Blocking:||Reproduced by developer:||no|
|Analyzed by developer:||no|
Summary of the bug:
When capturing some DVB-S and DVB-T broadcasts, we can see that the bitstream of the MPEG-2 and AVC/H.264 services include often the Active Format Description (adf): https://en.wikipedia.org/wiki/Active_Format_Description
This flag is usually transmited in:
- MPEG-2: As "User Data" section (user id: "DTG1").
- H.264: As "Auxiliary data" in a SEI unit (user id: "DTG1").
None of the current mpeg2 and h264 encoders handle that flag. However, as the Bitstream Filters for MPEG-2 (mpeg2_metadata) and H.264 (h264_metadata) can handle different flags similar to this, I request to add support for set/get the ADF flag.
