1.情况描述

使用简单的硬件解码程序读取rtsp视频，报错[ERROR] Decode channel 0 frame 5 failed, error 1，程序如下节。

2.解码程序：

from videocapture import VideoCapture
from acllite_resource import AclLiteResource
import time
import cv2
import numpy as np


if __name__ == "__main__":
    # rtsp_path = "rtsp://admin:Huawei123@10.233.38.35:554/liveMedia/ch1/Media1"
    rtsp_path = "/home/HwHiAiUser/project/coco_detection_rtsp/data/person.h264"
    p2 = 'rtsp:/192.168.2.119/554'
    # rtsp_path = '/root/hejingze/ECP_AI/temp/khll.mp4'
    pic_path = '/home/HwHiAiUser/Pictures/mobilenetv3-bneck.png'
    acl_resource = AclLiteResource()
    acl_resource.init()
    my_capture = VideoCapture(p2)
    num = 0
    start = time.time()
    while True:
        ret, frame = my_capture.read(False)
        if ret:
            print("error")
        else:
            if frame:
                num += 1
                print(frame.width, frame.height)
                
            else:
                print(time.time()-start)
                print(num) 
                break

3.输入rtsp视频流格式检查
