Eu compilei a libx264 no modo de 10 bits e compilei o ffmpeg nela. No windows BTW. Parece que quando eu codifico um vídeo com o meu ffmpeg, o meu Windows Media Player com o codec ffdshow é incapaz de reproduzir o vídeo. Eu usei o espaço de cores padrão x264 "yuv420p10le". O Ffdshow reporta o espaço de cores de saída como "P010" ao tocá-lo e não consigo obter uma saída de vídeo. Outros vídeos de 10 bits funcionam bem com o Ffdshow que reporta o espaço de cores de saída como "YV12". Eu usei os seguintes parâmetros para libx264: CC=cl ./configure --disable-cli --enable-static --host=mingw64 --bit-depth=10 e os seguintes parâmetros para ffmpeg: ./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
Eu usei o seguinte comando para converter: ffmpeg -i Input.mkv -vcodec h264 -an -sn Output.mkv
Esta é minha saída do ffmpeg:

Existe alguma opção que preciso adicionar ao realizar a conversão ou durante a fase de criação?
