emm,结果windows下报错连接不上youtube那个流的链接…新租的centos倒是可以…不知道是windows下的ffmpeg命令错了还是那个流不走代理…

centos下安装ffmpeg和youtube-dl:

yum install -y epel-release
sudo rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
sudo rpm –import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm
yum install -y ffmpeg

wget http://youtube-dl.org/latest/youtube-dl -O /usr/local/bin/youtube-dl
chmod a+x /usr/local/bin/youtube-dl

ffmpeg支持多个输出,linux下postCMD改为这个,边推流边保存到本地.

1
postCMD = ffmpegPath + ' -i "' + realFromPath + '" -c:v copy -c:a aac -b:a 320k -ar 44100 -strict -2 -f flv "' + toPath + '"' + ' -c:v copy -c:a aac -b:a 320k -ar 44100 -strict -2 -f flv "./tmp.flv"'

顺便,ffmpeg裁剪视频(指时间上裁剪):

1
./ffmpeg -i inputFilePath -ss 05:00 -c copy outputFilePath
