FFmpeg - Initiating codec parameters manually

Question

My application uses FFmpeg to demux and decode video streams from IP cameras. Video is encoded with either H.264, H.265, or MJPEG. Formats used include RTSP, and MPEG-PS. Currently I am using avformat_find_stream_info function to init format context when opening stream, and it works OK, but it introduces some delay at the beginning. I was able to reduce it by changing probe size, but I can't make it less than 2 seconds without making it unreliable. I would like to get rid of this delay.

I can get stream information from camera before opening it, so I wanted to initialize stream information in AVFormatContext without probing it. Is it possible with FFmpeg API?
