Comment (by Balling):
Yet with ffprobe -f ac3 m2ts it does recognize it as E-AC3!!!
{{{
[ac3 @ 0000021cebdadd00] Estimating duration from bitrate, this may be
inaccurate
Input #0, ac3, from 'C:\Users\ZAQU\stwqab.m2ts':
Duration: 00:00:51.03, start: 0.000000, bitrate: 94 kb/s
Stream #0:0: Audio: eac3, 48000 Hz, mono, fltp, 94 kb/s
}}}
So IMHO, this has ac3 core and eac3 dependent stream!
Ah, and yes, this no longer decodes at all with ffmpeg -f ac3 -i
TrueHDAC3.thd. This is a recent regression but before August 2020.
