ffmpeg 硬件加速/GPU H.264编码器参数

[mofeng-git]

实现在特定平台(Intel等）的H.264编码硬件加速

任务：

1. 验证可行性，测试Intel核显平台上ffmpeg h.264加速可行性
2. 实现demo，编写可运行脚本
3. 完善优化，脚本自动运行平台加载对应ffmpeg编码器
4. 集成进入kvmd主程序，引出配置选项

目前没有可以供 ffmpeg 硬件加速测试的平台，此计划暂时搁置。

详细信息：使用 CPU: Intel(R) Core(TM) i5-2410M (4) @ 2.90 GHz GPU: Intel 2nd Generation Core Processor Family] 硬件在 Windows 7/10、Ubuntu、Manjaro 系统中 ffmpeg 都无法使用 Intel 核显 QSV 视频加速功能。

Intel 硬件加速参考: https://github.com/eritpchy/pikvm-container/blob/main/root/usr/share/kvmd/stream.sh https://github.com/eritpchy/pikvm-container/blob/main/script/test_hardware_coder.sh qsv也有测试过, 是可用的, 但在我的机器效率只有VAAPI一半 1080p qsv 4x vaapi 8x左右

同理nvidia, amd支持其实也很简单

另外我的玩客云刷了你的系统老是无条件随机死机(可能硬件问题) 暂时是不会折腾玩客云版硬件加速了

utsreamer 已集成 libx264，性能尚可。暂时不会开发此功能，问题关闭。
