I'm getting raw H.264 data from a GenICam API call as a pointer to a buffer.
This pointer (as far as I examined it in gdb so far) does contain data that can initialze an AvPacket structure by setting the AvPacket.data field to the buffers address. Beforehand I initialized an AvCodecContext structure with the parameters that my received H264 data stream consists of (width/height, framerate, codec type, etc.) With this (the avCodecContext and the avPacket) I call avcodec_send_packet (avCodecContext, avPacket); and then avcodec_receive_frame( avCodecContext, avFrame); (with an allocated avFrame structure) Both calls return 0, which means that basically they succeded (looking into the structures in gdb, I would say, the values are also reasonable as far as I understand them). Now, in order to proceed processing with avlib, I understand that I need an AvFormatContext strucure somehow initialized. I read (and tested) many examples, where the initialization of that structure takes place in fucntions that also take a filename of a media file. Since I'm not working with a loaded file here, but with raw data received via an API call, I'd like to know, if it is somehow possible to initialize an AvFormatContext struct with the data I have at hand (the raw buffer, the avPacket and finally the avFrame)?
