Over what format? i dont know details about the application/lib using this, this patch was just the result of some investigation into why this other patch was needed: "[FFmpeg-devel] [PATCH 1/2] mux: make sure that the AV_PKT_DATA_H263_MB_INFO side data is received by the H.263/RTP packetizer (rfc2190)" > Shouldn't nut be able to handle all > these potentially ffmpeg-specific things? maybe the idea though was that a 5 line patch would avoid some application redesign work. And it may very well be usefull in various other scenarios.
