   I am using the code from branch v2.0.0 and found a problem:

   Decode Error occurred for picture 76303
   HW decoder faced error. Re-create instance

   This problem also appeared in earlier versions, and the solution is to catch the exception, e.g. #47 #353

   while True:  
       try: 
           rawSurface = nvD.DecodeSingleSurface() 
           if rawSurface.Empty(): 
               print('No more video frames') 
               break 
       except nvc.HwResetException: 
           print('Continue after HW decoder was reset') 
           continue 
   

   But in the branch v2.0.0, the HwResetException will not be thrown, why?

   I modified the source code to throw this exception, and decoding can continue , but there is another problem: a few frames are missing like issue #67 . The solution from @rarzumanyan was given in the issue_67 branch, but issue_67 has not been merged into the latest code, why?

   So, can this problem be solved in the new version? Thanks.

   I was also facing the same problem, where code runs for few minutes and then after running some time, starts throwing
   HW decoder faced error. Re-create instance constantly.

   I solved the problem after figuring out that some part of my code was occupying a large chunk of the cpu power resulting in decoding issue. Make sure you have sufficient cpu processing power (you can use top with ctrl+i to disable irix mode to monitor cpu usage).

   Also, make sure that no part of the code is running in a constant while loop without any delay (add sleep as it will reduce cpu power) .

   You can also check if you have enough decoding resources using the following command:
   nvidia-smi pmon

   How do I change the source code? I've also encountered this problem, which occurs after decoding H265 for a while.
