#5326 closed defect (fixed)

possible segfault in AvFormatDecoder::SetupAudioStream()

Description

In AvFormatDecoder::SetupAudioStream() codec_ctx could be null by the time it reaches line 4010. If it is dereferenced there it will segfault. This problem was introduced when ticket #5299 was fixed in svn revision r17268.

The possibility that this segfault happens is likely very small. But it does exist.
