For arm [SRS: arm](./arm.md#raspberrypi)
|
||
|
||
## OS settings
|
||
|
||
Login as root, set the fd limits:
|
||
|
||
* Set limit: `ulimit -HSn 10240`
|
||
* View the limit:
|
||
|
||
```bash
|
||
[root@dev6 ~]# ulimit -n
|
||
10240
|
||
```
|
||
|
||
* Restart SRS：`sudo /etc/init.d/srs restart`
|
||
|
||
## Publish and Play
|
||
|
||
Use centos to publish to SRS:
|
||
|
||
* Start FFMPEG:
|
||
|
||
```bash
|
||
for((;;)); do \
|
||
./objs/ffmpeg/bin/ffmpeg \
|
||
-re -i doc/source.flv \
|
||
-acodec copy -vcodec copy \
|
||
-f flv rtmp://192.168.1.105:1935/live/livestream; \
|
||
sleep 1;
|
||
done
|
||
```
|
||
|
||
* Play RTMP: `rtmp://192.168.1.105:1935/live/livestream`
|
||
* Online Play: [Online Player](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.flv&port=8080&schema=http)
|
||
|
||
## Client
|
||
|
||
The RTMP load test tool, read [srs-bench](https://github.com/ossrs/srs-bench)
|
||
|
||
The sb_rtmp_load used to test RTMP load, support 800-3k concurrency for each process.
|
||
|
||
* Build: `./configure && make`
|
||
* Start: `./objs/sb_rtmp_load -c 800 -r <rtmp_url>`
|
||
|
||
## Record Data
|
||
|
||
Record data before test:
|
||
|
||
* The cpu for SRS:
|
||
|
||
```bash
|
||
pid=`ps aux|grep srs|grep objs|awk '{print $2}'` && top -p $pid
|
||
```
|
||
|
||
* The cpu for srs-bench:
|
||
|
||
```bash
|
||
pid=`ps aux|grep load|grep rtmp|awk '{print $2}'` && top -p $pid
|
||
```
|
||
|
||
* The connections:
|
||
|
||
```bash
|
||
for((;;)); do \
|
||
srs_connections=`sudo netstat -anp|grep 1935|grep ESTABLISHED|wc -l`; \
|
||
echo "srs_connections: $srs_connections"; \
|
||
sleep 5; \
|
||
done
|
||
```
|
||
|
||
* The bandwidth in NBps:
|
||
|
||
```bash
|
||
[winlin@dev6 ~]$ dstat 30
|
||
