Is there a way (maybe with ffplay or ffprobe) to show the average q factor of
an already encoded video (or individual video frames)?
something like this that is shown after encoding:
[libx264 @ 0x7fdfeb82ae00] frame I:29 Avg QP:18.52 size: 74048
[libx264 @ 0x7fdfeb82ae00] frame P:1261 Avg QP:21.62 size: 17495
[libx264 @ 0x7fdfeb82ae00] frame B:3557 Avg QP:26.92 size: 2912
...or is this unknowable?
