ffmpeg都是c代码,所以不需要配置c++的sysroot。常用的就几个arch,cpu,cross-prefix,enable-cross-compile,sysroot,target-os,extra-cflags,extra-ldflags,enable-pic。现在Android和IOS几乎没有armv5的设备了,所以如果编译这两个平台配置armv7和armv8就好了。
But there should be more: there are at least four filters which have been enhanced to use QSV to transform videos faster with the GPU instead of the CPU, and you say nothing about the argument lists or how they can be used. I have found a very minimal list of the argume...

Assuming the nixpkgs package is vpl-gpu-rt. As nyanmisaka pointed out, that doesn't support my hardware (10th gen CPU, meaning Gen11 iGPU), and I have confirmed that in practice. As of this PR, the minimum I need to have fully featured HW transcoding (including tonemapping and subtitle...
注意,大多数加速方法适用于播放,但并不会比现代CPU软件解码更快。此外, ffmpeg通常需要解码帧从GPU存储器复制到系统存储器,从而导致进一步的性能损失。因此此选项主要用于测试。 -hwaccel_device[:stream_specifier] hwaccel_device (input,per-stream) 选择一个设备使用硬件加速。

FFMPEG项目是由法国人Fabrice Bellard发起的,此人也是著名的CPU模拟器项目QEMU的发起者,同时还是圆周率算法纪录的保持者。 FF是Fast Forward的意思,翻译成中文是“快进”。 FFMPEG的LOGO是一个”Z字扫描”示意图,Z字扫描用于将图像的二维频域数据一维化,同时保证了一维化的数据具备良好的统计特性,从而提高其后要进行的...
Hello there. I have an RX 7800XT GPU and I wanted to use AV1 GPU encoding on obs instead of SVT-AV1 CPU encoding. Currently, the only available are x264, AOM-AV1, and SVT-AV1. I am using Arch Linux, Hyprland (Wayland Compositer), the current stable release of the Mesa Driver...
