ffmpeg | branch: master | Martin Storsjö <martin at martin.st> | Sun Nov  6 23:51:19 2011 +0200| [ed307e2659f2db81a434afece905383fdceb9b6e] | committer: Martin Storsjö

rdt: Check the return value of avformat_open

If it failed, return NULL. This avoids trying to use an
half-initialized RDTDemuxContext.
