You aren't specific about what your "media" is... but I am assuming you are
streaming something equivalent to a file's contents. Your first task is to
figure out the container format and what it contains. This is the job of
libavformat, and the codec context is not relevant at this point.
I would recommend calling av_find_stream_info(AVFormatContext*) after opening
the stream. This will attempt to detect characteristics about the data,
including all the contained streams, and create codec contexts for you.

Hi,
Please have a look at ffplay.c file . av_open_input_file can take any RTSP
url as an input and can decode incoming packets from network.
if you are not using RTSP url to get the video packets then simply fill
the avcodeccontext structure in a right manner and start decoding the
incoming packets.

Hello ,
I would like to know if ffmpeg can decode chunks of video streams that
come from TCP packets, the av_open_input_file only opens a file
...How do I make it read streams from TCP packets .. Can you please
suggest ideas or alternatives?
