ffmpeg,live555,mplayer交叉编译

一.ffmpeg的编译

1.从官网http://ffmpeg.org/下载 ffmpeg-2.0.tar.gz

2.解压

tar -zxvf ffmpeg-2.0.tar.gz 

3.配置生成makefile

./configure --enable-cross-compile --cross-prefix=arm-none-linux-gnueabi- --arch=arm --target-os=linux

4.编译

make

5.用法

/rtsp

ffmpeg -y -i rtsp://192.168.0.50:8554/1.mkv -vcodec copy -acodec copy -f mp4 ./1.mp4      

二.live555的编译

1.从官网http://www.live555.com/liveMedia/下载live.2013.07.16.tar.gz

2.解压

tar -zxvf live.2013.07.16.tar.gz 

3.修改配置文件

打开config.armlinux文件

修改CROSS_COMPILE?= arm-none-linux-gnueabi-

4.配置生成makefile

./genMakefiles armlinux

5.编译

make

6.用法:

/live555MediaServer
LIVE555 Media Server
	version 0.78 (LIVE555 Streaming Media library version 2013.07.16).
Play streams from this server using the URL
	rtsp://192.168.0.50:8554/<filename>
where <filename> is a file present in the current directory.
Each file's type is inferred from its name suffix:
	".264" => a H.264 Video Elementary Stream file
	".aac" => an AAC Audio (ADTS format) file
	".ac3" => an AC-3 Audio file
	".amr" => an AMR Audio file
	".dv" => a DV Video file
	".m4e" => a MPEG-4 Video Elementary Stream file
	".mkv" => a Matroska audio+video+(optional)subtitles file
	".mp3" => a MPEG-1 or 2 Audio file
	".mpg" => a MPEG-1 or 2 Program Stream (audio+video) file
	".ts" => a MPEG Transport Stream file
		(a ".tsx" index file - if present - provides server 'trick play' support)
	".vob" => a VOB (MPEG-2 video with AC-3 audio) file
	".wav" => a WAV Audio file
	".webm" => a WebM audio(Vorbis)+video(VP8) file
See http://www.live555.com/mediaServer/ for additional documentation.
(We use port 8080 for optional RTSP-over-HTTP tunneling, or for HTTP live streaming (for indexed Transport Stream files only).)
使用方法:把同目录下指定格式的文件以rtsp流输出
将上述提到的格式文件保存在live555MediaServer同个目录下(例如:1.mp3),然后在rtsp播放器(例如:VLC)中用rtsp://[ip地址]:[端口号]/[文件名]播放(例如:rtsp://192.168.0.50:8554/1.mp3)
           

/live555ProxyServer
LIVE555 Proxy Server
	(LIVE555 Streaming Media library version 2013.07.16)

Usage: ./live555ProxyServer [-v|-V] [-t|-T <http-port>] [-u <username> <password>] [-R] <rtsp-url-1> ... <rtsp-url-n>
使用方法:将rtsp流转封装成统一格式的rtsp流
例如:运行./live555ProxyServer rtsp://192.168.0.50:8554/1.mkv 则打印下面信息
LIVE555 Proxy Server
	(LIVE555 Streaming Media library version 2013.07.16)

RTSP stream, proxying the stream "rrtsp://192.168.0.50:8554/1.mkv"
	Play this stream using the URL: rtsp://192.168.0.50:8554/proxyStream

(We use port 8080 for optional RTSP-over-HTTP tunneling.)
那么我们就可以直接用vlc播放rrtsp://192.168.0.50:8554/proxyStream这个地址
           

///openRTSP
Usage: ./openRTSP [-p <startPortNum>] [-r|-q|-4|-i] [-a|-v] [-V] [-d <duration>] [-D <max-inter-packet-gap-time> [-c] [-S <offset>] [-n] [-O] [-t|-T <http-port>] [-u <username> <password>] [-s <initial-seek-time>]|[-U <absolute-seek-time>] [-z <scale>] [-w <width> -h <height>] [-f <frames-per-second>] [-y] [-H] [-Q [<measurement-interval>]] [-F <filename-prefix>] [-b <file-sink-buffer-size>] [-B <input-socket-buffer-size>] [-I <input-interface-ip-address>] [-m] [<url>|-R [<port-num>]] (or ./openRTSP -o [-V] <url>)

打开rtsp流,解析保存成文件(./openRTSP -t -d 60 rtsp://192.168.0.50:8554/1.mkv)
           

三.mplayer的编译

1.从官网http://www.mplayerhq.hu/下载MPlayer-1.1.1.tar.xz

2.解压

xz -d MPlayer-1.1.1.tar.xz

tar xvf MPlayer-1.1.1.tar 

3.配置生成makefile

./configure --cc=arm-none-linux-gnueabi-gcc --host-cc=gcc --target=arm-linux

4.编译

make

5.用法

播放usb摄像头

mplayer tv://
