使用 ffmpeg 将 RAW yuv 转换为 mp4 视频时出错

我正在尝试使用 ffmpeg 将原始 yuv 视频转换为 mp4。

ffmpeg -f rawvideo -vcodec rawvideo -s 1920x1080 -r 25 -pix_fmt yuv420p -i Beauty_3840x2160_120fps_420_10bit_YUV.yuv -c:v libx264 -preset slow -qp 0 bb/output.mp4

我的视频出现错误。

ffmpeg -f rawvideo -vcodec rawvideo -s 1920x1080 -r 25 -pix_fmt yuv420p -i Beauty_3840x2160_120fps_420_10bit_YUV.yuv -c:v libx264 -preset slow -qp 0 bb/output.mp4

提供适当的-pixel_format和-video_size：

ffmpeg -framerate 120 -video_size 3840x2160 -pixel_format yuv420p10le -i input.yuv -vf scale=1920:1080 -r 25 -c:v libx264 -preset slow -qp 0 output.mp4
