ffmpeg 編譯出現
#sudo ./configure --enable-shared --prefix=/usr/local/ffmpeg
gcc is unable to create an executable file
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.
沒有安裝GCC，
#sudo apt-get install gcc
如果出現一下錯誤，錯誤的意思是 yasm/nasm 包不存在或者很舊
yasm/nasm not found or too old. Use --disable-yasm for a crippled build.
apt-get install yasm
安裝成功繼續回來安裝ffmpeg
