Adding user-defined SEI messages thru libavcodec/libx264
Hi, I am searching a way to insert private SEI messages before each picture when encoding with x264. As far as i see from the libx264.c code, it is not supported up to now. Am i correct ? If yes, i am willing to push patch to support this, but do you have a preferred way to do this (ie thru medata field of AVFrame ? thru sidedata of AVFrame ? ...) Thanks for your hints, Regards, SF

Hi, I was wondering if there's already a solution/workaround to this unanswered question...? I'm looking into the examples (remuxing.c, demuxing_decoding.c) and running with a file which has SEI messages (Closed Captioning) and they are not loaded into AVPacketSideData.data. The demuxing_decoding.c example uses the old avcodec API (avcodec_decode_video2/avcodec_decode_audio4) but there's also the note: "The new API does not handle subtitles yet." Is it possible to have ffmpeg (3.4.1) reading/writing SEI messages containing AV_PKT_DATA_A53_CC? What would be be the procedure? Thank you lyncher
