I-frame - a full complete picture for a single frame. I actually want an answer to this too, so I’m gonna try something different:.
Is it easier for me to google it, or to write a post about it, after logging in to my account here?įinding someone’s full on description of what the different frames types are is fine, it doesn’t really make it any clearer what changing the number does though does it? If nothing else it’s deliberately an insult. I too, think people’s attitude of “google it” is absolutely terrible. Only IDR-frames (and recovery points) close the GOPs. GOPs length in x264 is defined by -keyint and scenecut detection algorithm which can make GOP shorter than -keyint.Mostly if you will ignore the fact about ignoring IDR- vs I-frame difference.It doesn’t report it on the most x264 encoded files because it usually use adaptive (not constant) number of B-frames and adaptive GOP length (scenecut detection) but MediaInfo report this only when M and N is same for all file GOPs.
“N=” is constant delta between I-frames (btw, MediaInfo don’t make difference between IDR-frames and I-frames).
“M=” is constant delta between non-B-frames i.e.In the case of AVC you need to read File_Avc::GOP_Detect ( ) method.

MediaInfo is open source project so you can always look in to source code (that is what I did to answer your question) if not sure what some value mean. Classic with non real time encoding (quality optimization for the same final file size) e.g.Īny thought about why the encoding of the original might be lacking the GOP data? If it is variable, it obviously cannot produce a (constant) value for M and N. "Ultra HD"), is equivalent to a horizontal resolution on the order of 4000 pixels.I’ve seen several queries on the web which indicate that the GOP is only output if it is fixed for the whole video.
