Video Issues after upgrade from 4.2.4 to 7.0.1.241229

[lemmy999]

I have been running 4.2.4 for years and was hesitant to upgrade since it was working fine.  But I was having issues adding IPTV channels (I couldn't prevent it from adding all of the channels and then NPVR was too slow to use).  So I upgraded to the latest version using the method here:

https://github.com/sub3/NextPVR/wiki/updates-upgrades 

After the install, a web browser window opened to localhost:8866 so it was showing 4.2.4 (since 8866 is the v4 port and it was still running).  I closed the window, copied over the v4 config.xml and the npvr.db3 files to the C:\Users\Public\NPVR-data directory, edited the config.xml file to change the port to 8867 then started the web browser again with localhost:8867 and the latest version opened in the browser window.  Everything seems to be working fine, but for some reason when I view a channel, the video quality is worse and every 10-15 seconds it pauses for maybe 1 sec. After a few minutes the pauses seem to stop. I close the browser and opened the old V4 app and tuned to the same channel and looked better and there were no pauses. I also notice that changing channels takes much longer and once the channel changes, the pausing starts again. Is there some setting that could be causing this? BTW, my tuner is an HD HomeRun and I'm watching broadcast channels from my antenna, my machine is a Windows 10 machine and the browser is Chrome. 

Thanks.

What do you mean the old v4 app? If you mean the windows client v7 has nextpvr.exe too but you have to configure the decoder.

I'm not sure I follow.  When I open the NextPVR app, right click and select settings, it says 4.2.4, not v7.   On the 4.2.4 the MPEG2 decoder is set to ffdshow and so is H.264 decoder.  

In v7 (I am only able to access it through a web browser localhost:8867), I do not see anywhere to setup the decoder.  Only the Video Encoder and Auto Transcode (in the Transcoder section).

The old v4 NextPVR app is C:\Program Files (x86)\NPVR\Nextpvr.exe.  And I found the v7 app in C:\Program Files\NextPVR\client\NextPVR.exe.  When I opened that v7 app I see the ability to set the decoders. Thanks for pointing that out. So I guess there are no decoders to set for the browser server window.  Is that built in to the browser??

BTW, the decoders were set the same as for the v4 app.  I guess because I copied over the config.xml and npvr.db3 files from the v4 installation.

When I use the v7 app, the pausing and slow channel changing isn't happening.  So I guess I will manually make a link to this in the Start Menu.

Yes the browser client uses the browser playback.  The "decoding" is done by ffmpeg which encodes the signal to the restricted format a browser can use and streamed to the browser  That encoding is also why it is slower.

There was browser client in v4 (2 actually) you just may not have used them for playback.

Yes, I didn't realize there was a browser client for the old v4 until the v7 installation process opened localhost:8866 and I saw it was for version v4.
