我以 10 位模式编译了 libx264，并针对它编译了 ffmpeg。顺便说一下，是在 Windows 上。似乎当我使用 ffmpeg 编码视频时，带有 ffdshow 编解码器的 Windows Media Player 无法播放视频。我使用了默认的 x264 色彩空间“yuv420p10le”。播放时，Ffdshow 将输出色彩空间报告为“P010”，我无法获得视频输出。其他 10 位视频播放良好，Ffdshow 将输出色彩空间报告为“YV12”。我对 libx264 使用了以下参数：CC=cl ./configure --disable-cli --enable-static --host=mingw64 --bit-depth=10对 ffmpeg 使用了以下参数：./configure --toolchain=msvc --arch=x86 --extra-ldflags="-LIBPATH:/d/ffmpeg/lib" --extra-cflags="-I/d/ffmpeg/headers" --enable-yasm --enable-asm --enable-static --disable-shared --enable-gpl --enable-version3 --enable-libx264
我使用以下命令进行转换：ffmpeg -i Input.mkv -vcodec h264 -an -sn Output.mkv
这是我的 ffmpeg 输出：
