你好，我使用的是rk3399 pro，ubuntu18.04系统，请问下ubuntu支持这套方案吗？apt install rockchip-mpp，a ...

不支持，我们toybrick没有发布过ubuntu系统

好的，谢谢，我刷一下固件再试试。

请问这个“import toybrick as toy”这个toybrick工具怎么下载？给个下载命令看看可以吗？

版主你好，我刷了新固件，fedora系统，已经装好了RockX-1.2.0-py3-none-any.whl和python3-toybrick-0.2-12.aarch64.rpm，但是使用toybrick仍然报错，请教下什么原因？
>>> from rockx import RockX
>>> import toybrick

你是debian10还是fedora？这个直接安装opengl库就可以了

这行直接注释掉，因为这个demo做的东西和pyrockx重复了

谢谢回答，注释掉可以import。但是跑起来后一直卡在rtsp.read_rgb()这里使用的是海康摄像头，rtsp流确认过是正常的，请教下问题出在哪？代码如下：

1. #!/usr/bin/env python3.6
   
2. import os
   
3. import toybrick as toy
   
4. import time
   
5. import threading
   
6. 
   
7. if __name__ == '__main__':
   
8.     #url = "rtsp://cxqz:hb123456@192.168.1.64:554/ch1/main/av_stream"
   
9.     url = "rtsp://192.168.1.64:554/ch1/main/av_stream"
   
10.     usr = "cxqz"
    
11.     pwd = "hb123456"
    
12.     rtsp = toy.input.createRtspClient(url, usr, pwd)
    
13.     rtsp.connect()
    
14.     last = time.time()
    
15.     if rtsp.is_opened():
    
16.         print("hutx test")
    
17.         frame = rtsp.read_rgb(1280, 720)
    
18.         print("frame")
    
19.         now = time.time()
    
20.         print("> got frame. use = %.4f s" % (now - last, ))
    
21.         last = now
    
22.     rtsp.disconnect()
    

复制代码

你自己防火墙没关吧，摄像头没数据进来。iptable -F 试试

frame = rtsp.read_rgb(640, 360) 请问怎么将这个opengl的图像格式转成opencv图像格式？
