如何在Ubuntu中重新编译ffmpeg
我在Ubuntu中安装了ffmpeg,但使用了错误的方式——我只使用了——启用libass。现在我不能使用-crf选项,所以我想重新编译它 根据我键入的命令:如何在Ubuntu中重新编译ffmpeg,ubuntu,ffmpeg,Ubuntu,Ffmpeg,我在Ubuntu中安装了ffmpeg,但使用了错误的方式——我只使用了——启用libass。现在我不能使用-crf选项,所以我想重新编译它 根据我键入的命令: rm -rf ~/ffmpeg_build ~/ffmpeg_sources~/bin/{ffmpeg,ffprobe,ffplay,ffserver,vsyasm,x264,x265,yasm,ytasm} 然后我又开始编译: cd ~/ffmpeg_sources wget http://ffmpeg.org/releases/ff
rm -rf ~/ffmpeg_build ~/ffmpeg_sources~/bin/{ffmpeg,ffprobe,ffplay,ffserver,vsyasm,x264,x265,yasm,ytasm}
然后我又开始编译:
cd ~/ffmpeg_sources
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
--prefix="$HOME/ffmpeg_build" \

PATH="$HOME/bin:$PATH" make
make install
make distclean
hash -r
但当我键入ffmpeg
时,它仍然输出:
ffmpeg version N-77474-g11388b5 Copyright (c) 2000-2015 the FFmpeg developers

我很困惑,如何以正确的方式重新编译或删除ffmpeg
您在~/ffmpeg\u源
和~/bin/…
之间缺少一个空格
更重要的是,这是在$PATH
中拾取的ffmpeg吗?哪个ffmpeg
的输出是什么

此脚本将自动更新ffmpeg所需的所有库,如libnuma、YASM、AAC、CMake和libx265。事实是因为Debian/Ubuntu总是将软件的稳定版本包含在他们的repo中,而稳定版本有时可能会过时。因此,我需要下载最新的库并自己重新编译它
