Re: [Cin] oh, I see ffmpeg 4.4 in?

Andrea, ffplay always works this way for me and always has. So I just use ctrl+c.

Yes; trying a render with x265-10-bit and playing back the file obtained with ffply I get a freeze in the last frame with the last line of the terminal (indicating the momentary value: 19.46 A-V ...) that keeps increasing the number to infinity and I have to stop with ctrl+c. The same thing happens with DNxHR and x264. See image.
