NDigitalHost using a lot of memory

[nitram]

Hi, I haven't paid attention to how much memory NDigitalHost would normally use, but in the last week I see its Private Working Set rising to about 1.5GB within 10 minutes or so. This happens whether I am just watching Live TV with NextPVR, or just recording a broadcast program.
I have captured a set of events, seen in the attached logs, where I start watching Live TV, stop it, and then restart Live TV and leave it going until the Working Set peaks out at about 1.5GB. At this point NDigitalHost and NextPVR hang if you try and stop and restart Live TV. There is a PerfMon graph of the NDigitalHost Working Set in the attachment.

I can't be sure but I think the problem appeared when I installed all the latest Windows 10 Pro upgrades which have appeared since about last October. I am using the latest release of NextPVR.

I have tried re-installing elements such as LAV codecs, repair-installing .NET, uninstalling and re-installing NextPVR, upgrading video device drivers, and re-installing TV card drivers. Because this happens even when simply recording I am wondering if the TV card drivers are a problem, the card is a BlackGold 3620, and I see the latest device driver is quite old dating from 2011.

If anyone has any suggestions on this I would be grateful, if this behaviour isn't a NextPVR configuration problem maybe I should approach BlackGold for help.

I have found a workaround for this problem which might suggest a proper solution to someone. When I do NPVR upgrades I always store the previous program directory for the installation (e.g. C:\Program Files (x86)\NPVR) and the data directory (e.g. C:\Users\Public\NPVR) in case there is a problem and I want to switch back. I found that if I go back to using the NextPVR 3.9.2 program directory I had stored then the memory usage problem with NDigitalHost goes away. It is still there with any of the NextPVR version 4 stored program directories though.

NextPVR 4.1.0 solves my memory leak problem, that is great news.
Incidentally I found a simpler workaround eventually, which was to use the NShared.dll from 3.9.2 with the rest of NextPVR 4.0.5.
