Comment (by erik):
I instrumented the code to log the illegal values.
I use avformat for the demuxing and avcodec for decoding.
Will run the patched SW on a week worth of recording on 11 channels.
If there is no more crashing (and there used to be a lot) then at least I
am happy
But there is of course the possibility that this index error is a side
effect of another memory corruption error, then I am back to square 1
