Hi so I am experimenting with trying to grab video(mjpeg) from an IP webcam and I am using the Stepehen Dranger's tutorial01 as my starting point and I know that in his program he does a call av_find_stream_info to retrieve the stream information. Now I tried to feed the url of the ip webcam into his program and it fails at av_find_stream_info (which is expected because when I try to grab video from this IP camera using ffplay I have to do a -f mjpg to specify an input format). Now I am assuming I will have to manually allocate and set the values of an AVCodecContext variable. Now I have allocated a an AVCodecContext variable using av_allocate_context(). So what should I do next? What fields inside the AVCodecContext variable do I need to set so that I can pass it into avcodec_open()? Thanks

Now I went through the Stephen Dranger tutorial already but the tutorial reads from file, so how can I modify it to read from an IP camera? Any help would be appreciated.
