pcm bluray encoding
Thanks to Paul (who wrote a lot of ffmpeg code) I hacked this patch against ffmpeg-4.4. Can anyone test how it work with 5.1 and stereo sounds (s16, s24 broken ATM), especially if it remaps 5.1 channels correctly? I tested like this: $ ./ffmpeg -i ~/matrixbench_highdivx_ac3.avi -c:v libx264 -s 160x120 -c:a pcm_bluray -mpegts_m2ts_mode 1 -sample_fmt s16 1.m2ts mpv 1.m2ts but my tablet sound definitely not 5.1! NOTE: this is not yet cinelerra-gg patch, just something I test with our version of ffmpeg
oops. prev. patch was segfaulting on 2ch encodings (missing break!) new should work for mono and 5.1 (tested this time) On Monday, December 6, 2021, Andrew Randrianasulu <[email protected]> wrote:

or may be even this, supports (?) 7.1 if you have such config On Monday, December 6, 2021, Andrew Randrianasulu <[email protected]> wrote:

update: might even work for s32 (encoded as 24 bits) On Monday, December 6, 2021, Andrew Randrianasulu <[email protected]> wrote:

Andrew,
Can anyone test how it work with 5.1 and stereo sounds (s16, s24 broken ATM), especially if it remaps 5.1 channels correctly?
I tested like this:
$ ./ffmpeg -i ~/matrixbench_highdivx_ac3.avi -c:v libx264 -s 160x120 -c:a pcm_bluray -mpegts_m2ts_mode 1 -sample_fmt s16 1.m2ts
I can not test. We had problems with BT #326 and could not get our 5
speakers to make any sense.

may be just see if 'patch' can apply this combined (via use of >>) patch and ffmpeg still configures/compiles? I also spotted unfortunate bug/sideeffect of our ffmpeg-4.4.patch2 (bluray patch) - it breaks sound-only ts encoding... yeah, interesting idea about designing menu-drivem channel router (?) for audio tracks in this BT... Also, where you think we can put notes about tsmuxer and mp4box usage? In appendix? and... will you clean up old ffmpeg (4.3) and x264? I deleted them locally for saving few mbs of space and this may limit mergeability on my end..
