I'll start from the beginning to see if we can find the problem: I do the register all; I do a find_decoder (which is currently looking for "CODEC_ID_H264"); if that's successful, I allocate the context (using alloc_context3); I then do an avcodec_open2 with arguments of my context, my codec, and NULL for the dictionary; if this succeeds, I allocate the frame; next, I initialize a packet and set the packets data to the buffer I received which contains the H264 video; if that all works, i do a decode_video2.
The return is a -1 as i save it to a unique variable and print the result immediately; it also states that whole "no frame!" prior to my printout of the result. I feel like it's tied into either the AVCodecContext or the AVPacket (something I'm not populating in the packet besides supplying the buffer); but that's just a guess at this point. Thanks for taking time to look at this problem. -Neil P.S. If it matters, I'm using Live555 (because I need direct access to some of the RTP related data) to pull down my RTSP stream and passing along the buffer it returns.
