我正在设置 Sickbeard MP4 Automator（现在称为 Automator）来处理收到的视频文件。目前，我希望它能使用 NVENC 加速将每个文件转换为 x264，而不会出现明显的音频质量损失。我已将 Automator 设置为我认为可能有效的状态，其设置基于我在 GitHub 页面上发现的已解决的问题。
但是，我在 Automator 的 sma.log 中不断收到此错误，“不支持 10 位编码”

我尝试过使用 FFMPEG 进行软件编码，而不通过 Automator，结果发现转换效果很好。如果我通过输入这个来使用 CUDA 加速，ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i D:\torrentz\examplefile.mkv -c:a copy -c:v h264_nvenc -b:v 5M D:\transcode\waawe.mkv我也会出现 10 位编码错误，所以我不认为这是 Automator 的问题。但是，如果我确实需要调整某些东西，我也必须在 Automator 中进行调整，对吗？
这是我的 Automator 中的 autoprocess.ini。如果还有其他问题，请告诉我。

编辑：尝试后出现此错误-vf scale_cuda=format=yuv420p

我尝试使用-pix_fmt yuv420p，结果如下
Impossible to convert between the formats supported by the filter Parsed_null_0' and the filter 'auto_scaler_0'

编辑：
最后终于让 ffmpeg 和我合作了
ffmpeg -y -vsync 0 -i D:\foldee\examplefile.mkv -c:a copy -c:v h264_nvenc -pix_fmt yuv420p -b:v 5M D:\transcode\waawe.mkv
显然，根据帮助我的那个人的说法，你需要“混合使用 CPU 和 GPU 来处理 10 位颜色到 8 位，这意味着你不能要求 ffmpeg 使用 CUDA 硬件加速”。现在我只需要弄清楚如何让 Automator 工作。
答案1
我在三星 Galaxy S22 ultra 上以 1920x2080 拍摄了一段测试输入视频。Galaxy S22 使用 HVC1 编解码器对视频进行编码。
我可以使用以下命令行参数，利用 nvidia 硬件加速重新编码我的测试视频：
ffmpeg -y -vsync passthrough -v quiet -stats -hwaccel cuda -hwaccel_output_format cuda -i "ExampleVideo.mp4" -vf scale_cuda=format=yuv420p -c:a copy -c:v h264_nvenc -b:v 50M "ReencodedVideo.mp4"
