Re: [FFmpeg-user] nvenc h264 encoding
Le duodi 22 vendémiaire, an CCXXV, Sven C. Dack a écrit :
> If I'm not mistaken then yuv444p is linked to 10-bit depth encoding
Not necessarily. yuv444 is opposed to yuv420: with 420, pixels are grouped
as 2×2 squares, where all four pixels have their brightness ("y" =
"luminance") encoded, while the color ("u"/"v" = "chrominance") is the same
for all four; with 444, pixels have all three components coded individually.
That means that in 444, each pixels use three components, while in 420 they
only use 1.5 on average, half as much. This makes sense because the eye is
more sensitive to brightness changes than color changes.
10-bits depth is opposed to 8-bits depth, it measures the accuracy for each
component.
All four combinations are possible: yuv420p8, yuv420p10, yuv444p8,
yuv444p10. The 8 is usually not printed because it was for a long time the
only possible choice and is still the default. Of course, because of
compatibility problems, once you decide to ditch yuv420p8, you might as well
go all the way to yuv444p10, therefore the two intermediate ones are more
rarely seen. But yuv444p8 makes sense for screencasts, to avoid color
bleeding.
The p means that libavcodec stores the three components in three separate
memory areas rather than interleaved all together like rgb24.

If I'm not mistaken then yuv444p is linked to 10-bit depth encoding, which is only possible on the newer Pascal cards (the 10x0 series). The Video SDK page only mentions HEVC/H.265, but I believe it also applies to AVC/H.264. See here: https://developer.nvidia.com/nvidia-video-codec-sdk Try using "high" instead of "high444p" for the profile and "nv12" or "yuv420p" for the pixel format. If you want best quality for compression then add "-rc vbr_2pass -rc-lookahead 32" to the command line. The encoder cannot actually do two full passes, but it can look ahead up to 32 frames, which acts as a substitute for 2-pass encoding and can improve the picture quality a lot especially around I-frames.

[h264_nvenc @ 01d84640] No free surfaces Video encoding failed Conversion failed! Surfaces are a reference to the memory buffers used by the encoder. You can find out about which surfaces your graphics card supports by opening the Nvidia settings panel, -> "VDPAU Information", -> "Surface Limits". If your card doesn't support the pixel format or the picture exceeds the surface limit might this already explain why you get this error message. Although I would expect to see a different error message... You can also check with "nvidia-smi" which applications are currently using your graphics card. Suspended processes, zombie processes or just multiple processes can also exhaust the amount of available surfaces. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
