Comment (by JouMxyzptlk):
In the youtube video I hit ESC after five seconds to exit the video.
You can see the last line jumping around the values until "A-V: -4.354":
4.99 A-V: -4.354 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0
It is counting the negative time up.
I rechecked right not: It is still doing that strange thing, but only for
less than a half second now instead of forever. On the same machine, not
even a reboot.
"A-V:" is between -0.282 and -0.341 when ffplay exits. Shouldn't that
always be the same?
It never exited that testing video four hours ago when I tested before
creating the bug and creating the video. I saw the "A-V:" go below -30
seconds until I hit ESC.
Since I saw many reports about that I thought I had the actual reason
since I had a difference between keyframe intervals up to 240 videos and
others with smaller keyframe intervals.
This bug seems to be weird. I bet it will happen again.
