[FFmpeg-devel] Calling avformat_find_stream_info() more than once

[FFmpeg-devel] Calling avformat_find_stream_info() more than once

[Scott Theisen]

Hello all,

avformat_find_stream_info() calls av_freep() on FFStream::info, which 
will cause a segmentation fault if it is called more than once on the 
same AVFormatContext (assuming it still has at least one of the 
AVStreams from when it was called previously).

Is this intentional and should this be documented?

Thanks,

Scott Theisen

avformat_find_stream_info() is indeed not supposed to be called more
than once (on the same AVFormatContext).
