causeless_at_gmail
I think i could find the point.
FFmpeg mixes any chapters from the input files and creates incoherent chapters.
The following output shows merging process to create unreadable mp4.
(MKV ==ffmpeg==> WAV ==neroaacenc==> AAC, then, MKV + AAC ==ffmpeg==> MP4)
Original MKV has 5 chapters but output MP4 has 6, and chap#0.5 was broken.
