RK3399Pro入门教程（7）RTSP库的使用

这论坛现在都没人管了吗

给你们瑞星微提一个意见,你们,不开放demo,让我们学,我们就不会用你们的芯片,岂不是逼着我们不用你们的芯片?

toybrick@debian10:~/RtspHardDecoding-master/local_rtsp/build$
toybrick@debian10:~/RtspHardDecoding-master/local_rtsp/build$ cmake ..
CMake Error: The current CMakeCache.txt directory /home/toybrick/RtspHardDecoding-master/local_rtsp/build/CMakeCache.txt is different than the directory /home/toybrick/local_rtsp/build where CMakeCache.txt was created. This may result in binaries being created in the wrong place. If you are not sure, reedit the CMakeCache.txt
CMake Error: The source "/home/toybrick/RtspHardDecoding-master/local_rtsp/CMakeLists.txt" does not match the source "/home/toybrick/local_rtsp/CMakeLists.txt" used to generate cache.  Re-run cmake with a different source directory.

请问我执行，cmake..为啥会报这个错误呢？

toybrick@debian10:~/local_rtsp/build$ sudo dnf install -y python3-devel python3-opencv python3-numpy-f2py python3-h5py python3-lmdb  python3-grpcio
sudo: dnf: command not found

为啥没有dnf呀。
我的是debian系统的原因吗？

为啥我执行cd local_rtsp/build
cmake ..
的时候会报如下的错误呢？
toybrick@debian10:~/Documents/local_rtsp/build$ cmake ..
CMake Error: The current CMakeCache.txt directory /home/toybrick/Documents/local_rtsp/build/CMakeCache.txt is different than the directory /home/toybrick/local_rtsp/build where CMakeCache.txt was created.

是路径不对，然后我修改了路径之后执行又报如下的错误了

为啥我执行这个会报这个错误呢？是我有什么依赖没有安装吗？
我查看了g++的版本
看了600多行的log，看不懂，想放弃。
楼主能踢我一脚吗？

你好，你这个怎么解决的，我也遇到这个问题

这个问题是什么原因呢？

我在RV1126调用librockchip_rtsp出现如图所示错误：

1. [2023/09/20 08:31:20] D/: listening rtp port 22540
   
2. [2023/09/20 08:31:20] D/: listening rtcp port 22541
   
3. [2023/09/20 08:31:20] D/: listening rtp port 22550
   
4. [2023/09/20 08:31:20] D/: listening rtcp port 22551
   
5. [2023/09/20 08:31:20] D/: curlto rtsp://192.168.0.239/test , cli 22540:22550, tcp: 0
   
6. terminate called after throwing an instance of 'std::bad_alloc'
   
7.   what():  std::bad_alloc
   
8. Aborted
   

复制代码

安装采用如下形式：

1. sudo apt install rockchip-rtsp rockchip-rtsp-dev libcurl4-openssl-dev

复制代码这个视频流可以用VLC播放器秒开，是1920*1080的H.264编码的视频流

1. 流 0
   
2.     编解码器: H264 - MPEG-4 AVC (part 10) (h264)

4.     视频分辨率: 1920x1080
   
5.     缓冲分辨率: 1920x1088
   
6.     帧率: 25
   
7.     已解码格式:
   
8.     方向: 上左
   
9.     色度位置: 左
   
10. 流 1
    
11.     编解码器: PCM ALAW (alaw)
    
12.     类型: 音频
    
13.     声道: 单声道
