Summary of the bug:
I came across a live channel (multicat.ts) which is recorded from
satellite.
When trying to copy the stream with ffmpeg it fails.
When trying to transcode the stream with ffmpeg it succeeds.
How to reproduce:
Download the file ffmpeg_report.zip and unpack it.
Inside the folderm the original file is called 'multicat.ts'.
Run the bash script "copy.sh" to produce a copy of the file named
'copy.ts' (the bad file)
Run the bash script "transcode.sh" to produce a transcoded variant of the
file named "transcoded.ts" (the good file)
Expected behaviour:
The copy.sh bash script should produce a file in similar size to the
original multicat.ts file and be playable with video players.
