I need to transcode a video to another one with the following properties:
- GOP size is always fixed at a given value
- Only IDR frames are used as key-frames (not I-slices)
- SPS/PPS/VPS frames are repeated every time before the IDR frame.
Is there a way to do this with ffmpeg?
Also, it would be great if you can also tell me of a simple way of verifying all this (perhaps using ffprobe?).
