ffmpeg硬件编码加速参数

2020年06月26日

参考内容:https://trac.ffmpeg.org/wiki/Capture/Desktop https://developer.nvidia.com/ffmpeg https://ffmpeg.org/ffmpeg-devices.html

在使用ffmpeg进行视频编码转换、视频录制、视频截剪、视频合并、视频加字幕、视频和音频合并等操作的时候,ffmpeg会很占资源并且会很慢,那么我们可以打开它的硬件加速参数来进行操作,提高工作的速度。

我们需要知道我们系统支持哪种硬件编解码方式和哪些编码器和解码器,这个可以用以下三个ffmpeg的参数获取到。

Windows
D:\ffmpeg\bin\ffmpeg.exe -hwaccels
Linux
ffmpeg -hwaccels

如果你的显卡是英特尔 HD Graphics系列的,需要安装英特尔的支持模块:https://software.intel.com/en-us/intel-media-server-studio

如果你的显卡是英伟达/NVIDIA系列的,需要安装Nvidia出的一个GPU计算库CUDA: https://developer.nvidia.com/cuda-downloads

Intel QSV

Intel QSV (Quick Sync Video) is a technology which allows decoding and encoding using recent Intel CPU and integrated GPU, supported on recent Intel CPUs. Note that the (CPU)GPU needs to be compatible with both QSV and OpenCL. Some (older) QSV -enabled GPUs aren't compatible with OpenCL. See: ​https://www.intel.com/content/www/us/en/architecture-and-technology/quick-sync-video/quick-sync-video-general.html ​https://software.intel.com/en-us/articles/intel-sdk-for-opencl-applications-2013-release-notes

To enable QSV support, you need the Intel Media SDK integrated in the Intel Media Server Studio: ​https://software.intel.com/en-us/intel-media-server-studio

The Intel Media Server studio is available for both Linux and Windows, and contains the libva and libdrm libraries, the libmfx dispatcher library and the intel drivers. libmfx is the library which selects the codec depending on the system capabilities, falling back to a software implementation if the hardware accelerated codec is not available).

FFmpeg QSV support relies on libmfx, but the library provided by Intel does not come with pkg-config files and a proper installer. Thus the easiest to install the library is to use the libmfx version packaged by lu_zero here: ​https://github.com/lu-zero/mfx_dispatch

Requirements on Windows: install the Intel Media SDK packaged in the Intel Media Server Studio, which comes with a graphic installer, and a MinGW compilation enviroment (for example provided by MSYS2 with a corresponding Mingw-w64 package). Then you need to build libmfx and install it in a path recognized by pkg-config. For example if you install in /usr/local then you need the update the$PKG_CONFIG_PATH environment variable to make it point to /usr/local/lib/pkgconfig.

Requriments on Linux: you need either to rely on the Intel Media Server Studio for Linux, or use a recent enough supported system, with the libva and libdrm libraries, the libva Intel drivers, and the libmfx library packaged by lu_zero. Note: in case you use the Intel Media Server Studio generic installation script, the installation script may overwrite your system libraries and break the system.

Check the following website for updated information about the Intel Graphics stack on the various Linux platforms: ​https://01.org/linuxgraphics

To enable QSV support in the FFmpeg build, configure with --enable-libmfx.

Support for decoding and encoding is integrated in FFmpeg through several codecs identified by the _qsv suffix. In particular, it currently supports MPEG2 video, VC1 (decoding only), H.264 and H.265.

For example to encode to H.264 using h264_qsv, you can use the command:

ffmpeg -i INPUT -c:v h264_qsv -preset:v faster out.qsv.mp4

 

You can use hardware acceleartion to speed up encoding and reduce the load on your CPU. For example, with NVIDIA hardware encoding:
ffmpeg -f gdigrab -framerate 30 -i desktop -c:v h264_nvenc -qp 0 output.mkv

 
注:其中 h264_nvenc -qp 0 中的 h264_nvenc 是使用显卡加速操作,这个和ffmpeg默认的 lib264 或 h264 参数是一样的,但这个速度更快。

例如:视频转换,可以使用以下指令

D:\ffmpeg\bin\ffmpeg.exe -hwaccel cuvid -i a.mp4 -vcodec -c:v h264_cuvid -acodec aac -ar 44100 -vf scale=1920:1080 b.mp4
D:\ffmpeg\bin\ffmpeg.exe -hwaccel nvenc -i a.mp4 -vcodec -c:v h264_nvenc -acodec aac -ar 44100 -vf scale=1920:1080 b.mp4
#英伟达显卡
D:\ffmpeg\bin\ffmpeg.exe -hwaccel qsv -i a.mp4 -vcodec -c:v h264_qsv -acodec aac -ar 44100 -vf scale=1920:1080 b.mp4
#英特尔显卡
D:\ffmpeg\bin\ffmpeg.exe -hwaccel dxva2 -i a.mp4 -vcodec libx264 -acodec aac -ar 44100 -vf scale=1920:1080 b.mp4
D:\ffmpeg\bin\ffmpeg.exe -i a.mp4 -acodec aac -vf scale=1920:1080 -vcodec libx264rgb -crf 0 -preset ultrafast b.mp4
ffmpeg -i a.mp4 -vcodec libx264rgb -crf 0 -acodec aac -ar 44100 -vf scale=1920:1080 b.mp4
-hwaccel cuvid:指定使用cuvid硬件加速
-c:v h264_cuvid:使用h264_cuvid进行视频解码
-c:v h264_nvenc:使用h264_nvenc进行视频编码
-vf scale_npp=1280:-1:指定输出视频的宽高,注意,这里和软解码时使用的-vf scale=x:x不一样
