Hi In a recent commit, AVCodecContext was modified in a way that it's now not compatible across all versions of FFmpeg and LibAV.
I had opened ticket https://trac.ffmpeg.org/ticket/5057 but it's been decided that it won't be fixed. I was given an alternative, cross-platforms way to set AVCodecContext using AVDictionary to set most of the fields. However, that leaves me with how to modify the extradata / extradata_size member. For the context, in the project I work on (Firefox), we do not ship with any ffmpeg or libav libraries. We simply attempt to dlopen whichever one is present and will do what needs to be done in setting the decoder. We also do not use libavformat, only libavcodec and the decoding part. As such, we manually extract the extradata (either from the inband SPS/PPS or from the mp4 container). I don't see a way on how we could access the AVCodecContext::extradata member that would work across all versions of libavcodec wherever it's coming from. Any ideas? thanks _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
