Cannot detect HVR-950

There is also another problem with the web interface.  That is, the web interface apparently needs to authenticate into the server (it asks for the userID and password) to do anything - to watch TV to look at the guide, etc.  However, much of the time the web interface fails to ask for authentication.  So if I click around at enough menu items I'll stumble over one that forces the web interface to ask for authentication and then once I authenticate in - everything works.  But if I can't get it to ask for authentication, then things won't work on the web interface.

There is an issue where your browser will sometimes show cached versions of the web page, without going to the backend server, so you can get shown pages before it's logged in. Eventually it does go to the backend server, and gets the login page. I've tried a couple of things, but it's difficult to force the browser to not cache pages. It's still on my 'need to improve this' list.

If you tick the 'remember me' check box when logging in, you shouldn't have any problems from then on.

Ran the NextPVRuninstaller.  Program crashes after deleting the files in the directory and does NOT remove the
service.

2) Uninstaller fails to kill tray icon process and service before attempting to uninstall them
3) Uninstaller fails to remove itself from the Programs & Features listing and fails to delete the uninstall script from the programs directory

I found the cause of all these. The most recent installer wasn't pointing Windows at the right executable for the uninstaller, so it wasn't actually trying to do an uninstall (it was just trying to run an extra copy of NextPVRServer.exe, instead of NextPVRUninstall.exe).

I've updated the https://nextpvr.com/NPVRSetup.exe to point to the correct uninstaller executable. (for now it's still installing the same release, but the install will point to the correct uninstaller executable)

For the next release of the application, I've fixed the missing runtime SlimDX requires, and made a couple of improvements around install/uninstall.

I've run into the cached thing before with regular webserver stuff.

"by the book" the "fix" is for the webserver to issue a pragma=no-cache or cache-control=no-cache on every page there is a discussion of this here:

https://stackoverflow.com/questions/1031...ol-headers

It is a royal PIA to get Apache to do it. (I know you aren't using apache of course)

But even then there's web caches out there that override this, and I would not be a bit surprised if some browsers do also.

In 1999 I worked for a company that was developing a custom web app and the developer was tearing his hair out on this one. His eventual solution as ugly as it is, was to append a random string of garbage at the end of each action item so a post from the browser would throw the URL plus the garbage which the application program would just trim off. I have seen that solution in use over the past 21 years. It's ugly but effective.

I have been working on the caching problem this morning, and think I’m on the right track for a fix.

Thanks I look forward to the next release and testing out the player - this lockdown stuff is terrible, I guess we are all going to be watching a lot of TV!!

2 more things that I ran into today I don't know if it matters, but here they are.

I use OTA epg and some stations provide 24 hours of EPG some only 6 hours or so. I did run across the trick of running nextpvr out of schedule multiple times a day to keep the guide updated. The web page in Settings for NextPVR seems to indicate it's possible to put more than 1 time a day to pull the epg - it uses plural for the schedule - but only has 1 spot for 1 time.

It appears that PowerDVD 10 installs MSC+ 2005 redistributable. (I used an old copy of PowerDVD mainly to be able to play DVD's in the DVD player in the PC) This old of runtimes does not seem to bother the NextPVR server the way the 2010 runtimes did.

You can just put a comma, then another time.

That said, the North Amercian broadcast EPG is terrible, and most people in that part of the world get a Schedules Direct account. It's dirt cheap, and gives you multiple weeks of listings, with very useful info like season/episode numbers, great artwork etc (without the artwork guesswork you get with the broadcast EPG.

Old runtimes shouldn't cause any issues. The only think that uses the 2010 runtime is the slimdx dll, and having the runtime installed should meet it's requirements. Other runtimes like 2005, 2003 etc aren't used at all.

Thank you for that I would suggest you put an example with a single time and a multiple time with a comma on the webpage that has the time entry box.

I noted the recommendation for Schedules Direct in older posts. It might be worth it if there was a good show like "Orville" on broadcast right now and I wanted to setup a scheduled recording. There is not at the moment so all recording I am doing is one-off. Perhaps in the future if a decent show is put on I will get it but for now broadcast epg is usable "with kludge" :-)

As I noted when I installed the 2010 runtime it caused the server to crash when attempting to access the server from either the web browser or the desktop app. Uninstalling the runtime stopped the crashing.

I would assume a newer version of PowerDVD would require a newer runtime such as the 2010 runtime, which would trigger the crashing issue. I am assuming that the next version will resolve whatever conflict is causing that.

If you've still get a setup with this error happening, can you supply some logs or error messages?

I just tried a clean VM here, with Win10, and NextPVR, and the VS2010 runtime from https://www.microsoft.com/en-us/download...px?id=5555. It didn't seem to cause any issues. In fact, it fixed the previously mentioned issue missing runtime required by slimdx, and allowed nextpvr.exe to run correctly. Web app also seemed to be functioning fine. This test was done with the current version installed via https://nextpvr.com/NPVRSetup.exe

OK I ran another test:

cleaned system as per directions
loaded vc runtime 2010 from the link above (that is the same link I had used to download it previously)
loaded version 5.0.2.200322 of NextPVR
Loaded LAV Filters from here:
https://www.videohelp.com/software/LAV-Filters
these are the same build as the GitHub link you provide.

Launched desktop client - as soon as I did that the tray icon went red. Now I realize I was assuming the
server was crashing, it was not. Instead I am assuming that the tray icon and the desktop client both
want the same resources and access to the server and the tray icon is booted out when the desktop
client runs.

right clicked Settings on desktop client and
clicked Decoders and selected the LAV Video codecs for all video codecs and LAV Audio codecs for
all audio codecs (I did not know I had to do this until the live TV failed in the desktop client and
I had to go digging for the answer)

Microsoft DTV-DVD Video Decoder was selected for some of these but it doesn't appear to
work at all out of the box. I don't know if Microsoft just installs a sort of "placeholder"
decoder or what. I did not try following the hack for extracting the codec from the Microsoft
update and installing it.

For grins I tried selecting the PowerDVD version 10 codec for video - it decodes - but very jerky and slow.
It works fine when you run PowerDVD 10 on the desktop but that's it. Probably a newer powerdvd
might have a faster codec.

I don't have WinTV installed on the machine although I have the CD for it.

The entire codec situation kind of needs an explanation during installation - I kind of feel like I stumbled into a working
setup. The http://www.nextpvr.com/decoders.html page is good but I didn't see it until after I
went looking for it. I would suggest a popup message added to the installer stating "without installing a codec pack
the desktop viewing program may display a black screen" Since a fresh win10 system has no codecs that are usable, this might help
knock down a "gotcha"

It does not appear necessary to install ANY codecs at all if your only TV watching client is a web browser or
an android phone or something.

As soon as exited the desktop app the tray icon went green again.

I can't start nextpvr.exe at the moment ... from memory ... Settings -> Decoders has a link at the bottom pointing to the decoders.html page.

NextPVR.exe is a stopgap pending delivery of a new NextPVR player app.

You are correct that it is only nextpvr.exe that requires decoders.  NextPVR Server produces streams that are comptible with the built-in decoders used by web browsers, Android and iOS.
