Comment (by jamrial):

 Looks like they are not copying codec parameters from the
 AVStream.AVCodecParameters struct to the avcodec_alloc_context3 allocated
 context before calling avcodec_open2.
 The function avcodec_parameters_to_context should be used for this
 purpose.

 Can't really test but it could be the source of the problem.
