How can I make sure that non-keyframes are not reaching avcodec_decode_video() until the first keyframe is decoded ?
 
Hello,
 
I think that all the non-keyframes that arrive to the avcodec_decode_video() function are discarded by this function automatically and the function will begin working when one keyframe arrives. So you don't need to worry if the first frame arriving to avcodec_decode_video() function is keyframe or not.
