翻了几个帖子，关于硬件解码的比较少。
代码也是这个代码
import cv2
print(cv2.__version__)
cap = cv2.VideoCapture("rtsp://192.168.10.113:554/ch1/main/av_stream")ret, frame = cap.read()
while ret:
ret, frame = cap.read()
if not ret:
continue
cv2.imshow("frame0",frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cv2.destroyAllWindows()

echo 0x0100 > /sys/module/rk_vcodec/parameter/debug
来打开硬解码调试信息，看下日志就知道有没有走硬解码
-----》没有打印日志，为什么呢？

帧率非常低现在，应该是cpu解码了。。

感谢回复，下载下来autoconf的时候，报了很多缺的东西，这个组件编译前有没有需要安装的包列表？我统一下载一下，谢谢。github上面没有介绍编译的方法
