[Ubuntu] HTTP Live Streaming 安装测试
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/
m3u8 檔案格式
#EXTM3U #EXT-X-TARGETDURATION:10 #EXTINF:11, http://192.168.0.10/gt4_pre-1.ts #EXTINF:11, http://192.168.0.10/gt4_pre-2.ts #EXTINF:11, http://192.168.0.10/gt4_pre-3.ts #EXTINF:11, http://192.168.0.10/gt4_pre-4.ts #EXTINF:5, http://192.168.0.10/gt4_pre-5.ts #EXT-X-ENDLIST
