================== 执行ffmepg命令行 ================= =

一切似乎都正常，然后我执行了以下命令：
ffmpeg -c:v h264_cuvid -i ./holidy.mp4 output.mkv
但结果是：
[h264_cuvid @ 0x55f93a512200] Codec h264_cuvid is not supported.

以下是全部信息：

我尝试了宽度CUDA9.0，CUDA9.1，FFmpeg3.4，FFmpeg4.0，FFmpeg 4.1，但是它报告了相同的错误。谁能帮我？我将非常感谢您！

答案 0 :(得分：1)

就放弃。

不幸的是，GeForce 820m是完全基于Fermi的基于Fermi的GPU。

答案 1 :(得分：0)

根据Nvidia Video Encode and Decode GPU Support Matrix（snapshot）， GeForce 820m支持NVENC和NVDEC。如果我的理解是正确的，则支持NVENC和NVDEC的Nvidia图形卡也应在FFmpeg中支持h264_cuvid解码器。所以我认为@halfelf的回答是错误的。
