ffmpeg 版本升级到 4.0 增加 libaom 库

Posted 2020-11-01 1CM

win10 中交叉编译 libaom 时 注意事项

libaom 源代码 下载 git -c "http.proxy=ip:port" clone https://aomedia.googlesource.com/aom

1. perl 版本需要 5.10.1 以上

2. Disable the use of the gtest‘s CMake support.  set(AOM_DISABLE_GTEST_CMAKE 1)

ffmpeg.exe  -i 00.mp4 -strict -2 -c:v libaom-av1 -b:v 2000k -crf 30 -cpu-used 4 -threads 8 -f matroska 00.mkv

ffmepg 中目前 libaom-av1 Codec is experimental , 缺点是普通 pc 上 编码速度非常慢;
