Yes, when I've wrote frames into the file, ffplay could play it, so I
think that troubles are in my code.
I have an access to sources of the application, which send this stream
to the network, so I can read a code which prepare codec context before
encode frames. But I can't understand, how I need to prepare codec
context to decode it. :(
Which parameters are important for decoding context? Is it enough to set
only width, height and pix_fmt? I need to configure context manually
because I have no any headers, which usually available in file on the
disk. I have only buffer with frame, length of the frame and information
is this frame is key frame or not.
p.s. excuse me, my English isn't good, but I hope you have understood me. :)
