Dear all, I am implementing a fast seeking with libavformat and libavcodec. For this I want to do something with possibly large distance between two sequential keyframes. In short, my plan was to cache some decoded P-frames and then substitute them as pseudo keyframes on-flight when needed. Let's say the GOP size is 250, then I can cache 5-10 intermediate P-frames to speedup seeking.
My question is: is it possible to inject such pre-decoded frame into the codec and start decoding from it and not from the original keyframe? Or am I insane? Best regards, Vadim
