Version 6.1.4 initial install problems

I only need to see the NextPVR.exe logs so if you aren't using it it won't help. I am not surprised that a modern. Celeron can handle NextPVR at all

It still has problems.  Was a long game.  Started out fine.  Still problems while watching and trying to skip forward.   Both the UI version and the EXE.   Looks like that integrated video IS working.   When using the UI version, same stuttering, slow start etc. but also sometimes stops playing and reports an error with the encoder.  Similar issues with the exe ver but of course there is no encoder error as the encoder is not in play with the exe version (if I understand it correctly)   The issues with the playback and lockups etc. happen with both the UI and EXE version.   Went crazy at the end of the game.  Couldn't delete the finished recording and kept reporting that the recording was in use?  Couldn't cancel it either.   Tried various ways to cancel or delete it after a while it finally allowed me to delete it.   I'll have to go back to waiting for the shows to finish recording and then watching the completed recording with the Windows Media player or VLC.   I've tried four different media players on the recorded shows and playback is always perfect and jumping forward or back is instant and works perfect.  Just doesn't work or play right with Nextpvr.   Logs attached.

What exactly does it say?

Went crazy at the end of the game. Couldn't delete the finished recording and kept reporting that the recording was in use?

I think a feature latest release is responsible for this. In the logs it looked like it was still trying to generate the thumbnails for this recording. On the Settings->General page of the web app, set Generate Thumbnails to 'None' to see if it helps with the next recording.

It was likely a case of your slower machine being a bit slow trying to generate the thumbnails for multiple recordings at the same time. Having this thumbnail generation happening going for multiple recordings also left not enough CPU for your machine to transcode the stream for playback in your browser.

In theory, attempting to delete the recording should stop the generation of thumbnails. I'll have to check this new feature is working correctly.

1. It looks like you still haven't installed LAV32

2. Your experience wtih the web playback will be very poor since your PC can't transcode at real time speed

3. There is a known issue with loading thumbnails for long recordings and that will be worse on your slow machine.

4. You cancel recordings which means (I think) your thumbnails and timing file will be short by about 25% because of the slow transcoding. If you turn off thumb extraction do things improve?

5. Post processing thumbnails will spike CPU use. If you want to use the feature I think you need to try it while recording. Try sub's suggestion to use None first though.

6. You tried to delete the recording while it was playing in the web browser. Stick with NextPVR.exe IMO.

7. Do you use closed captioning?

My Reply: Yes originally installed LAV 64 AND 32 a few months ago .. NO errors etc.   Thought it was working.   I have since un-installed and re-installed it 3 times.  Each time says complete with no errors.  Today I have been working on JUST this LAV issue  all day.  I have installed it several more times all with the same results.   I have since CONFIRMED that although everything HERE says LAV is working and installed, it is NOT working.  I've attached a couple Screen Caps of  1. my installed Windows 11 Apps (all LAV linstalled) and also 2. cap of my Nextpvr setting screen showing LAV as the installed codec.  Note the one area in that NPR Settings screen that keeps changing back FROM  every attempt I make to make it LAV instead of the MS DTV thing.  Keeps switching to the MS DTV codec.  MAYBE this is the prob?

2. Your experience wtih the web playback will be very poor since your PC can't transcode at real time speed
Yup I've found that to be true.  All the other four media players I have installed all work smoothly and eror free BUT I assume that's cuz they are NOT doing any encoding. 

3. There is a known issue with loading thumbnails for long recordings and that will be worse on your slow machine.
Yes, I can confirm that.

4.  You cancel recordings which means (I think) your thumbnails and timing file will be short by about 25% because of the slow transcoding.  If you turn off thumb extraction do things improve?
Hard to recall because I've been testing so many times (going a little stir crazy now)  <grin>  BUT I'm pretty I have done exactly that in the past and you are correct there also.  I think I have seen a change when I set it to execute after the recording is finished  Sorry, not sure if that's what you mean. 

5.  Post processing thumbnails will spike CPU use.  If you want to use the feature I think you need to try it while recording.  Try sub's suggestion to use None first though.
I've tested with processing (real time) and set to "post processing" ... If that is what you mean then yes it makes a difference but mostly only in the improved "flow" and shorter delays during playback.  The common thng to both is the total freezng and lock up.    I may be confusing this because (for example) the thumbnail thing here is only available in the EXE version.  I can advance video position in WEBUI ONLY by using the mouse to move the  position pointer in the time line.  Hitting the right and left arrows in the web UI does not bring up the thumbnals navigation at all.  Don't know if that's normal or not.     However using the NextPVR.EXE both the mouse grab and move works AND the right and left KB arrows DO bring up the Thumbnail option which does work. 

6.  You tried to delete the recording while it was playing in the web browser. Stick with NextPVR.exe IMO.
Have been doing mostly that (using the EXE) which works better but still has issues.   But if I want to skip quickly ahead or back (to skip commericals etc.) it's slow and will often freeze completely requirng me to  hit <esc> and restart the video playback.  During a 2 or 3 hour sporting event this happens a LOT so  I now use VLC to watch the shows after NPVR has finished recording.  All the other installed media players play smoothly and perfecting with instant jump ahead etc.   (JUST like the old  NPVR vers 4 usse to do) 

7. Do you use closed captioning?
Yes probably 90 percent of the time of the time.   All the tests here with this issue have been done with and without closed caps and I haven't seen any issues with that at all.

I think right now I'd like to just concentrate on this LAV issue which I think might be the underlying problem.   See my attached two screen caps for more details.  NOTE!   When using any of my other Media Players .. (which have options for displaying the codecs in use) NONE of them ever show LAV.   However the NPVR settings DOES show LAV as being installed except for the "HEVC Video" and "AAC Audio"  codecs.   I keep changing them from the MS DTC codec to LAV and they always revert back to MS.  Also the 2nd screen cap shows LAV installed in my Windows 11 OS apps listing. 

Last note worth mentioning again.   Months ago this Windows 11 PC was working PERFECTLY WITH the old NextPVR vs 4 which was installed in this brand new PC . That was in August 2022.   Then several weeks ago (Late june 2023) Windows had a major upgrade.   I HAD windows updates turnned off for some tiime before that and normally manually turn it on every month or so and let it update it's OS.  I do that so my "TV viewing" doesn't get interupted.  <grin>   So  several weeks ago I decided to do my bi-monthly Windows check up and let it do all the previously scheduled OS upates.  It installed "Win vers 22H2".   The old version was 21H2.   And there were a lot of things changed.   The biggest change was that my NextPVR vs 4 started to have many issues.   After weeks of trying to get my beloved vs 4 to work I finally decided to make the switch to version 6.    So now I don't have the old vs 4 at all, and also have a lot of issues with NextPVR 6.   

I have two other PCs, that are still running the latest win 10.  they have also had that recent upgrade to Windows 22H2 this past June.   (of course it's a "different build number than my win 11 PC)   So I'm thinking I might just install a vs 4 of NPVR on that Win 10 pc (which I have done in he past and DOES work but was when that Win OS was still version 19xxx .  So I'll stick Npvr on that PC  (running 22H2) and see if NPVR vs 4 still works.   Sorry, just a little "thinking out loud here". 

So HOW do we fix this LAV issue.  I have spent HOURS researching that today and can't find any relavant info.   THANKS very much for sticking with me on this.  I really appreciate the help.

Check the NextPVR.exe decoder settings with the right click. Just installing LAV is not good enough.

Closed captioning might also be an issue with NextPVR.exe. the yauiclient might be better for you.

Sorry - don't understand ... Where do I find "NextPVR.exe" decoder settings?  If you mean right clicking on the NextPVR "codec" screen options then right clicking on "anything" there does nothing.    If you mean right clicking on the NextPVR.exe in the windows OS program files folder, I don't see anything concerning "codecs" in that context menu ?  

I suspect I'm not seeing what you are referrng to because although it is being listed as being installed it is  NOT actually installed.  Could you tell me exactly where I would find that NextPVR.exe decoder you are referring to?  What is it's actual name?   I can do a deep scan of every file existing on the drive to find it if needed

Closed captioning doesn't seem to be an issue.  It always works perfectly thu every test.  But for our diagnositcs here let me know if should turn if off during future tests.   I have done most of the several dozen recent tests with it both tuned on and off and saw no change.

He has already been on that screen (if you look at his screen shots) the problem being is when he changes it to LAV it doesn't stick.

Yeah.  According to the Wiki link I need to right click the NextPVR executable in the Windows "Program Files" folder (where it is installed)   So here is what that right click ontext menu looks like.   Don't think there is any Video Codec related item in that list ??
