Ffmpeg : Improve results with h264_nvenc video codec
7 avril 2024, par SulliI was very happy to discover ffmpeg is compatible with Cuda as using a GPU speeds up my processing time by 10 at least. But I was very sad to discover codec libx264 can’t be used and h264_nvenc is of much poorer quality (my videos are visibly pixelated, to the point I actually don’t see why ffmpeg was made compatible with Cuda in the first place :) ).


I did not tweak my ffmpeg commands at all when I switched from libx264 to h264_nvenc, but maybe there are some parameters I could add to get a better quality ? Even if it leads to longer processing time, I don’t mind trading a bit of that for a better quality. Or maybe another video codec I wouldn’t know about ?


I usually run my scripts on Google Colab if that matters (tesla T4 graphics card, Driver Version : 535.104.05, CUDA Version : 12.2)

lavc/qsv_hevc : correct QSV HEVC default plugin on Windows
12 décembre 2018, par Zhong Lilavc/qsv_hevc : correct QSV HEVC default plugin on Windows
1. Old logic meaned : everywhere, except Windows, ffmpeg has to use HW
acceleration, but on Windows ffmpeg has to use (unavailable) software
HEVC by default
2. Software HEVC is available only if you provide corresponding
software MediaSDK library, which isn't provided with ffmpeg. More
information could be found in
https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/samples/readme-encode_linux.pdf
3. HW HEVC decoding/encoding are available on Windows in the driver by defaultNote : Default case should be the most common case but this change still has potential risk
on windows if HW path is not supported(or doesn't work as expection).
(See the historical disscution : https://lists.libav.org/pipermail/libav-devel/2016-November/080419.html).
In such case, two options suggested :
1. Use the option "-load_plugin hevc_sw" to switch SW path manually.
2. Or report bug to Intel windows driver if your GPU can support HEVC HW codec.
(HEVC decoding is supported since Braswell, and encoding supported since Skylake)Patch started by Landgraph. Add similar change for hevc decoder and bump a new version.
