Comment (by Balling):

 Maybe the actual patch is that this line
 https://github.com/FFmpeg/FFmpeg/blob/b741a84a15aed8afa01800dbc4b8b0e344e5d2da/libavformat/aviobuf.c#L265

 should add || whence != SEEK_END

 That was laster whence can be SEEK_END and will in fact work only if
 whence contained AVSEEK_FORCE flag.
