I'm trying to figure out how to determine the display order for the
frames returned by the x264 encoder as it is used by FFMPEG. The encoder
doesn't appear to fill in the display_picture_number member of the
coded_frame (AVFrame struct).
I did a little digging in the FFMPEG code and the x264 code and I didn't
immediately see how to determine this information. I'd appreciate any
suggestions or help.
