SRS支持arm,在树莓派上成功运行,本文记录了树莓派的性能指标。
树莓派下安装和运行SRS,有以下方式:
- 编译源站和运行:SRS在arm/raspberrypi下的编译,参考Build: RaspberryPi
- 直接下载binary文件,然后安装运行,下载RespberryPi的安装包:Github站点 或者 国内镜像站点。安装方法见页面。
查看SRS是否启动:/etc/init.d/srs status
本次测试的硬件环境如下:
- RaspberryPi:B型
- SoC BroadcomBCM2835(CPU,GPU,DSP,SDRAM,USB)
- CPU ARM1176JZF-S(ARM11) 700MHz
- GPU Broadcom VideoCore IV, OpenGL ES 2.0, 1080p 30 h.264/MPEG-4 AVC decoder
- RAM 512MByte
- USB 2 x USB2.0
- VideoOutput Composite RCA(PAL&NTSC), HDMI(rev 1.3&1.4), raw LCD Panels via DSI 14 HDMI resolution from 40x350 to 1920x1200 plus various PAL and NTSC standards
- AudioOutput 3.5mm, HDMI
- Storage SD/MMC/SDIO socket
- Network 10/100 ethernet
- Device 8xGPIO, UART, I2C, SPI bus, +3.3V, +5V, ground(nagetive)
- Power 700mA(3.5W) 5V
- Size 85.60 x 53.98 mm(3.370 x 2.125 in)
- OS Debian GNU/linux, Fedora, Arch Linux ARM, RISC OS, XBMC
另外,直播不会用到SD卡,所以可以忽略不计,用的是class2,4GB的卡。
软件环境如下:
- RaspberryPi提供的img:2014-01-07-wheezy-raspbian.img
- uname: Linux raspberrypi 3.10.25+ #622 PREEMPT Fri Jan 3 18:41:00 GMT 2014 armv6l GNU/Linux
- cpu: arm61
- 服务器: srs 0.9.38
- 客户端:flash + st-load
- 网络: 百兆交换机(pi只支持百兆)
流信息:
- 码率:200kbps
- 分辨率:720x576
- 音频:无音频
环境搭建参考:SRS: arm
