Preface
The function expansion of Android's camera is becoming more and more abundant. Recently, because of the need for RTSP push, I have a little understanding of the pits that have been stepped on.
Server
The server-side project developed by pure JAVA, used a few years ago, is still easy to use today.
- spydroid-ipcamera
- Use high-level instructions
such as: Use audio and video->rtsp://xxx.xxx.xxx.xxx:8086?aac&h264
Client
On the client side, it is recommended to use VLC on the PC, which is very convenient for debugging and powerful. On the
mobile side, this point is to talk about, after all, a few years ago, the deep pit that I stepped on was it:
- Awesome Open Source find open source projects from here
Then, the result after trying is:
- SmarterStreaming [x] is too big, can’t get down, impatient...
- EasyPlayer-RTSP-Android [v] Need to apply for APPID, domestic open source SDK routine
- EasyPlayer-RTSP-Android-APK [v] Need to apply for APPID, domestic open source SDK routine
- RTSP.Player.Android [v] finally adopted this, the effect is also good, but the compatibility has not been tested.
delay
This is a common question
- The VideoView/MeidaPlayer control on the mobile phone often finds a 5 second delay after playing
- Use VLC test on PC, under default settings, it will be about 2 seconds
At the beginning, I suspected that it was a problem on the server side. After a lot of time toss, I can only say that I was still too young.
- Connection settings in VLC:
reduce the cache appropriately, for example, change 1000ms to 200ms - On the mobile phone, you have to find a useful playback control or tool
RTSPPlayer : This project used to work well, but the recent test found that it often fails to connect or there is no image or screen after connecting. In the interface, the delay can support about 100ms .
vlc-android : How to say it, powerful, but to be able to toss very much, once downloaded and compiled, the final result is not satisfactory (different from the official released APK performance)
