I've tested to convert MP2 audio to AC3, E-AC3 and AAC respectively
with default bit rate in my remuxed "HDV.m2ts" file for Blu-ray<br>
<br>
Stream #0:1[0x1100]: Audio: ac3 (AC-3 / 0x332D4341), 48000 Hz,
stereo, fltp, 192 kb/s<br>
Stream #0:1[0x1100]: Audio: eac3 (EAC3 / 0x33434145), 48000 Hz,
stereo, fltp, 192 kb/s<br>
Stream #0:1[0x1100]: Audio: aac (LC) ([6][0][0][0] / 0x0006), 48000
Hz, stereo, fltp, 128 kb/s<br>
<br>
Re. aac, ffmpeg reported:<br>
[mpegts @ 0x5620ca0a9580]<br>
Stream 1, codec aac, is muxed as a private data stream and may not
be recognized upon reading.<br>
<br>
Playback with VLC and and Gnome Videos movieplayer (Totem) was ok
for AC3 and E-AC3<br>
No audio for AAC.<br>
<br>
I think I go for E-AC3 for "HDV.m2ts with re-encoded audio" on
Blu-ray discs<br>
