需要注意的是,要使用Nvidia GPU硬编解码,你的计算设备必须配备了支持NVDEC功能的Nvidia显卡。大多数现代Nvidia显卡都支持NVDEC和NVENC,因此在这些设备上可以利用Nvidia GPU硬编解码来提高视频编解码性能。 总的来说,Nvidia GPU硬编解码是一种利用Nvidia显卡硬件加速的视频编解码技术,它可以在视频处理中提供更高的性能、...
可以看到这条: DEV.L. hevc H.265 / HEVC (High Efficiency Video Coding) (decoders: hevc hevc_qsv hevc_cuvid ) (encoders: libx265 nvenc_hevc hevc_nvenc hevc_qsv ) 解码器提供了hevc,hevc_qsv,hevc_cuvid; 编码器提供了libx265,nvenc_hevc,hevc_nvenc,hevc_qsv,但是这个nvenc_hevc其实已经作废了,...
