安裝 Apache

apt-get install apache2

在/etc/apache2/mods-available/mime.conf加入以下內容：

# HLS file type

AddType application/x-mpegURL .m3u8

AddType video/MP2T .ts

Ubuntu 11.04 預設的 FFmpeg 是沒有啟用 h.264 的支援，所以要自己編譯。

安裝編譯時所需要的套件

apt-get update

apt-get install build-essential checkinstall subversion git libfaac-dev libjack-jackd2-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libsdl1.2-dev libtheora-dev libva-dev libvdpau-dev libvorbis-dev libx11-dev libxfixes-dev libxvidcore-dev texi2html yasm zlib1g-dev libx264-dev librtmp-dev

編譯 FFmpeg

cd /opt

git clone git://git.videolan.org/ffmpeg

cd ffmpeg

./configure --prefix=/usr --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --disable-ffplay --enable-shared --enable-gpl --enable-postproc --enable-version3 --enable-nonfree --enable-avfilter --enable-pthreads --enable-vdpau --enable-librtmp

make -j$(grep processor /proc/cpuinfo |wc -l)

checkinstall --pkgname=ffmpeg --pkgversion="5.0.1" --backup=no --deldoc=yes --default

segmenter 是用來切割 FFmpeg 轉好的 ts 檔

編譯 segmenter

cd /opt

svn co http://httpsegmenter.googlecode.com/svn/trunk

cd trunk

sed 's//local//g' Makefile.txt > Makefile

make -j$(grep processor /proc/cpuinfo |wc -l)

checkinstall --pkgname=segmenter --pkgversion="2" --backup=no --deldoc=yes --default

測試影片轉檔

cd /var/www

ffmpeg -i gt4.avi -f mpegts -vcodec libx264 -acodec libmp3lame gt4_pre.ts

ffmpeg -i gt4.avi -f mpegts -acodec libmp3lame -ar 48000 -ab 64k -s 720x480 -vcodec libx264 -b 800k -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -subq 5 -trellis 1 -refs 1 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 200k -maxrate 800k -bufsize 800k -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect 720:480 -g 30 -async 2 gt4_pre.ts

測試 RTMP 串接轉檔

ffmpeg -i rtmp://flashstream.adobe.com/ondemand/flash/cs5/prod/production-performance_400x224 -f mpegts -vcodec libx264 -acodec libmp3lame rtmp_pre.ts

測試影片切割

segmenter -i gt4_pre.ts -d 10 -o gt4_pre -x stream.m3u8 -p http://192.168.0.10/

利用 pipe 從轉檔到切割

ffmpeg -i gt4.avi -f mpegts -vcodec libx264 -acodec libmp3lame - |segmenter -i - -d 10 -o gt4_pre -x stream.m3u8 -p http://192.168.0.10/
