Bug#657200: Endless loop in avformat_find_stream_info()

[Matthieu Bedouet]

I had a very similar issue with kfilemetadatareader (from kdelibs-bin)
and mkv files.
The backtrace looked the same.
(kfilemetadatareader uses libstreamanalyzer that uses libavformat)

Applying this patch to libavformat solved the problem:

lavf: prevent infinite loops while flushing in avformat_find_stream_info
