[FFmpeg-user] Encode subtitles, 5.1 audio into MT2S format

[Sampath Subasinghe]

Hi All,
           I tried various options to get a .srt subtitles file, and 5.1 
audio into a mt2s file.


ffmpeg  -i input.mp4 -vcodec copy -acodec aac -i subtitle.srt  -f mpegts 
out.mt2s

input.mp4 already has h264 video and 5.1 audio. Then I get this error.

[mp2 @ 0x17bdc20] encoding 6 channel(s) is not allowed in mp2
Output #0, mpegts, to 'out.mt2s':
     Stream #0.0: Video: libx264, yuv420p, 1280x534 [PAR 1:1 DAR 
640:267], q=2-31, 90k tbn, 23.98 tbc (default)
     Stream #0.1(eng): Audio: mp2, 48000 Hz, 5.1, s16, 64 kb/s (default)
Stream mapping:
   Stream #0.0 -> #0.0
   Stream #0.1 -> #0.1

Please let me know how to do this correctly. The reason I want this is 
that I want to play it in a Sony Bravia TV that only supports subtitles 
in  mt2s container.

thanks.
