Comment 5 for bug 467730

av_cold shouldn't matter on Linux, but was necessary to compile on Windows with the compiler I'm using, where the cold attribute is broken.

The ogg-size patch fixes ffmpeg to always read in the duration of an ogg file. Without this, the function will seek to the end of the file, not read in the last granule, and hence not set the duration properly for an ogg file that is less than 65307 bytes long. IIRC, I sent this patch in a while ago, not sure what's happening with it.

Thinking about this a little more, it's possible that this problem relates to some seek issues I fixed a while ago. Can you go to:
