Summary0000263: eac3to v3.28 abort decoding TrueHD Atmos from a BD
Descriptioneac3to v3.28 abort decoding TrueHD Atmos from a BD:
[a02] Extracting TrueHD stream...
[a02] Removing TrueHD dialog normalization...
[a02] Decoding with libav/ffmpeg...
[a02] [libav] major sync info header checksum error <WARNING>
[a02] The libav decoder reported error -1094995529 while decoding. <ERROR>
Aborted at file position 1048576. <ERROR>

The mpls have only 1 m2ts, here is the first 100 seconds and the full log with the error: [^]

eac3to can extract the ac3 core and the thd, the ac3 is ok but the thd is not recognized by eac3to or ffmpeg.
ffmpeg can decode the Atmos track from the m2ts without problems.

Same problem reported by others users with this spanish BD.

This problem was caused by eac3to trying to remove the dialnorm information from the TrueHD stream. The dialnorm edit didn't honor the Atmos information. This will be fixed in the next build.
