[Ffmpeg-devel] [PATCH] Reload stream parameters after initial seek in ffmpeg

[Wolfram Gloger]

Sorry for not following up earlier on the seek issue.
I'm trying to split my patch further.

Now that av_find_stream_info() is callable anywhere within a stream,
the following patch lets it be invoked after the initial seek.  This
is definitely necessary for mpeg-ts which can contain completely
different stream/codec parameters in different parts of a stream.

Regards,
Wolfram.
