Hi Sean,
Thanks! I believe that Keyframes are written to video stream, done as work for the Player. So I guess it would be StartKeyFrame EndKeyFrame. It would have to start at StartKeyFrame and run 'n' keyframes and stop. So its a matter of scanning the video stream file for keyframes. That is challenging. I am a C programmer, but know not how to identify a keyframe while reading the stream.

I think it would be done by guacenc, though, not by ffmpeg. I'd think that guacenc just wouldn't start sending the frames to be encoded until, while reading the input file, guacenc has reached the start time and stop sending frames to be encoded at end time.

And then only generate MV4 between those points. This is a theoretical question, Many thanks, Adrian
