like to open the H.264 codec with some basic parameters, encode a few
frames, then modify the encoding parameters, and then encode other frames.
I looked on the Internet, but I didn't find a solution. According to the
standard, it's possible, but I don't know (didn't find ?) how to do this
properly with the FFmpeg API.

There is no special solution you need to simply destroy the codec instance
at some point and create a new one. The question is what you will be doing
to the results of encoding. If you are building a container with
interleaved audio stream, etc., like mp4 file, such switch will not work
out of the box.But for are streaming a raw h274 video the simple approach
is enough.

Good luck,
