channels / unknown stream

--------------------------------------+----------------------------------
When trying to decode a DVB-S recording with teletext streams in it, these
streams are mistaken as e.g.
- {{{Stream #0:1[0x68], 127, 1/90000: Audio: mp3, 0 channels, s16p}}}
- {{{Stream #0:5[0x69], 2, 1/90000: Unknown: none}}}
This is with ffmpeg 2.5.2.
Full ffprobe-report created with
{{{% ffprobe sample.ts -report}}}
and sample.ts are attached.
Some more details about the streams:
- Stream #0:0[0x65]: video (correct)
- Stream #0:1[0x68]: First teletext PID, misrecognized as MP3 with 0 ch.
- Stream #0:2[0x6a]: real audio (AC3)
- Stream #0:3[0x67]: real audio (mp2)
- Stream #0:4[0x66]: real audio (mp2)
- Stream #0:5[0x69]: Should be second teletext PID, recognized as
"unknown"
