像素格式‘yuv420p10le’与编解码器 libx265 不兼容

我在用

ffmpeg -probesize 2G -i input.ts -c:v libx265 -pix_fmt yuv420p10le -x265-params fps=50 -c:a libfdk_aac -t 00:00:05 /output.ts

我收到错误

incompatible pixel format 'yuv420p10le' for codec libx265m, auto-selecting format 'yuv420p'

我正在尝试从具有 yuv420 像素格式的 UHD 视频创建具有 10 位颜色深度的 UHD 视频

有任何想法吗？

答案1

问题在于您的 x265 编码器仅支持 8bpp：

build info [Mac OS X][clang 6.0.0][64 bit] 8bpp

您必须获得具有高位深度支持的最新 x265。由于您使用的是 macOS，因此我会使用自制。如果你之前已经使用 Homebrew 安装了 x265/ffmpeg，请使用reinstall而不是：install

brew install x265

然后，我将重新安装 ffmpeg：

brew install ffmpeg
