My application decodes video stream, processes it by its own means and saves

To save it to a file, it initializes input AVFormatContext with custom
AVIOContext, then uses usual cycle:

What's wrong with it?

Sometimes my application writes to a file encoded video, and similar code
(the only difference is in options and iformat) works fine.
