Comment (by Kamedo2):

 Replying to [comment:151 cehoyos]:
 > If you have time, it would be interesting to compare to the quality of
 other FFmpeg audio encoders, ie ac3, eac3 and mp2.
 It may be wrong, but I guess the ac3 is the most used variant. The bitrate
 will be around 128kbps, so the extremely high bitrate of eac3 will not fit
 the frame, I think. Are there some important use of eac3 and mp2, other
 than the BD and VCD encoding? (For BD the space is huge and quality at
 lower bitrate is insignificant.)
