[BUG] MKV Advanced Video Signaling Options Have No Effect

[Selur]

Okay, I can reproduce the issue:

I:\Hybrid\64bit>mkvmerge --ui-language en -o "E:\Output\using5.mkv" --global-tags "E:\Output\mkvtags_2022-07-27@16_31_24_2910__02.xml" -d 0 --default-track 0:yes --colour-matrix 0:5 --default-duration "0:25/1fps" --aspect-ratio-factor 0:1/1 --fourcc 0:MP4V --no-chapters --compression -1:none --forced-track 0:yes --field-order 0:0 --no-audio --no-subtitles "E:\Output\2022-07-27@16_31_24_2910_01.264"
mkvmerge v69.0.0 ('Day And Age') 64-bit

'E:\Output\2022-07-27@16_31_24_2910_01.264' track 0: Using the output module for the format 'AVC/H.264 (unframed)'.
The file 'E:\Output\using5.mkv' has been opened for writing.
Progress: 100%
The cue entries (the index) are being written...
Multiplexing took 0 seconds.

results in:

=> They both seem to be the same.

Then I looked at the output of mkvinfo for '0:5':

-> seems to me like a bug in ffmpeg.
