我的预期功能是：就是decode解码然后在显示器上循环播放视频。
但是我一模一样的程序在x3上跑的了，能正常显示视频，但是在x5上就是一直报错 不明白是哪里有问题。
报错如下
贴一下完整代码：
import sys, os, time
import numpy as np
import cv2
from hobot_vio import libsrcampy
def test_decode_bind_display():
#decode start
dec = libsrcampy.Decoder()
dec1 = libsrcampy.Decoder()
dec.decode("/root/face/wmzn.h264", 0, 1, 1920,1080)
# print ("Decoder return:%d frame count: %d" %(ret[0], ret[1]))
dec1.decode("/root/face/wmzn_b.h264", 5, 1, 1920,1080)
# #display start
disp = libsrcampy.Display()
ret = disp.display(0, 1920,1080, 0, 1)
print ("Display display 0 return:%d" % ret)
ret = libsrcampy.bind(dec, disp)
# print("libsrcampy bind return:%d" % ret)
# time.sleep(21)
num = 1
while True:
time.sleep(7)
# print(num)
# print('togg')
if num:
dec1.close()
ret = dec1.decode("/root/face/wmzn.h264", 4, 1, 1920,1080)
ret = libsrcampy.unbind(dec, disp)
ret = libsrcampy.bind(dec1, disp)
num = 0
else:
dec.close()
ret = dec.decode("/root/face/wmzn_b.h264", 2, 1, 1920,1080)
ret = libsrcampy.unbind(dec1, disp)
ret = libsrcampy.bind(dec, disp)
num = 1
ret = libsrcampy.unbind(dec, disp)
print("libsrcampy unbind return:%d" % ret)
disp.close()
dec.close()
print("test_decode_bind_display done!!!")
# test_decode()
while True:
test_decode_bind_display()
