using FFMPEG to setup HLS server on Ubuntu

来源：互联网发布：中国什么发生战争知乎编辑：程序博客网时间：2024/06/09 14:38

1. environment setup in Linux OS
1). install libx264 to support h264 encoder
sudo apt-get install libx264-dev

2). install FFMPEG with libx264 library
sudo apt-get install ffmpeg

3). install VLC into the OS
sudo apt-get install VLC

2. setup TS server using VLC
using the vlc transcode commond as before
vlc -vvv udp://@239.192.58.3:1234 --network-caching=10 --sout
'#transcode{vcodec=h264,venc=x264{keyint=25,idrinit=25,bframes=0,
ref=1,hrd=cbr,crf=28,vb=4500,preset=ultrafast,tune=zerolatency,vbv-maxrate=1200},
fps=25.00,threads=48,deinterlace,audio-sync}:udp{caching=10,mux=ts,dst=192.168.0.1:5050,name="testTS1"}'

3. using ffmpeg to receive the TS & slice it into small TS file indexed by m3u8 file(we can also use other parameters, such as size -s)

ffmpeg -re -i udp://@ip:port -vcodec libx264 -acodec aac -strict -2 -segment_time 10 -threads 24 -f hls webURL

比如：m3u8-segmenter -i udp://@:1234 -t 8 -d 5 -n 100 -p test -m test.m3u8 -u /test/

-i --input file path or URL
-vcodec --video codec
-acodec --audio codec
-segment_time --ts duration time
-threads --number of threads
-f --hls

webURL --the address which clients can access.such as http://192.168.0.8/videos/test.m3u8

搭建X264环境

1. x264
1). download the newest code:
git clone git://git.videolan.org/x264.git

2). configure the x264:
./configure --enable-shared

3). make && sudo make install

2. ffmpeg
1).download the newest code:
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

2). configure the ffmpeg(if we don't needs AAC, we don't need "--enable-libfaac --enable-libfaad --enable-libmp3lame")
./configure --enable-gpl --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libx264

3).make && sudo make install
