Summary of the bug:
Audio is not supported. The video samples dvbt2_small.ts is recording of
free German DVB-T2 TV channel "Das Erste HD". Unfortunately sound track
AAC format is not supported/implemented with FFMPEG version 3.3.2. Since
this year (March 2017) new DVB-T2 standard is broadcasting in Germany and
France. Unfortunately FFMPEG doesn't implement support of some audio
formats of this standard.
How to reproduce:
{{{
ffmpeg -i dvbt2_small.ts
}}}
or
{{{
ffplay dvbt2_small.ts
}}}
The problem related to audio track:
Stream #0:1[0x552]: Audio: aac (LTP) ([15][0][0][0] / 0x000F), 22050 Hz,
5.1, fltp, 1077 kb/s
Errors are:
- More than one AAC RDB per ADTS frame is not implemented. Update your
FFmpeg version to the newest one from Git. If the problem still occurs, it
means that your file has a feature which has not been implemented.
- Too large remapped id is not implemented. Update your FFmpeg version to
the newest one from Git. If the problem still occurs, it means that your
file has a feature which has not been implemented
FFmpeg version:
OS: Arch Linux, ffmpeg version is taken from Arch Linux repository.
