Vero 4k iptv issues after August update

nunojsa · 4 September 2021 23:15

Hi,

I’m having a lot of trouble with the pvr iptv client . I’m experiencing audio out of sync with video and the are also channels taking significant time to load and to change between them. Also to mention that if I enable the new timeshift/catchup feature than it becomes completely broken (streams completely black or constantly buffering). I think this might also be related with some other threads I saw about issues with deinterlacing issues.

I already tried to move .kodi to a backup directory to start fresh with no luck. I was about to do a fresh installation when I stumbled against some threads that can be related to my issues so I’m holding it for now. On top of this, I have some h265 channels that I realized that they work just fine. This makes me wonder that this can be a more subtle issue related with h264 interlaced streams that a fresh install might not really fix. Hopefully this is not some regression on the kernel drivers.

Also to note that I’m only having issues with live tv playback…

This is very unfortunate as the rest of the update actually went fairly smooth and I was really looking forward for this update to get the timeshift/catchup feature…

Here are some logs:

Note that I removed a lot of stuff from the pvr addon (Loading channels) otherwise I could not even upload the whole log. Hopefully I did not removed anything important…

Thanks!

Are recordings of the same channel affected?

nunojsa · 6 September 2021 07:31

I’m not sure I’m following the question but I think the records are fine. I mean, I can use the feature (catchup/timeshift) on the same channel on both my phone and laptop (linux based) but not on OSMC/Vero.

What @sam_nazarko meant is if you record a TV Show to a file and then try to play that file on the Vero instead of live TV is the issue the same?

nunojsa · 6 September 2021 08:46

Ahh, I see. Not sure, any easy way to record the stream? I know there was an IPTV recorder addon that no longer works in Matrix. Other way I have is to just install Leia and try that addon to record a small sample…

LubosD · 6 September 2021 19:53

Hey guys, my PVR playback is suffering from the same issue as described here after August update. The source is H.264 interlaced.

Unlike OP, I don’t use IPTV in the sense of OTT, but rather “IPTV” coming from Tvheadend/DVB-S2 on my local network.

When I play back a recording, it is just as bad as playing the live stream.

I have uploaded a sample TS file (saved with wget) here: https://drive.google.com/file/d/1RJP85VCk2HLmML5E88xN1W6PbIveVsAI/view?usp=sharing

The video will play at 50% speed and then occasionally catch up with audio.

nunojsa · 6 September 2021 20:28

@LubosD, nice that you could share a record. I did tried to run the recorder addon in vero but it is failing. And recording the channel in a working machine probably does not make sense as I guess it should be fine to play that back on vero…

sam_nazarko · 7 September 2021 01:36

Please post some logs.

nunojsa · 10 September 2021 21:05

Anything else that I can do to help? @LubosD can you share some logs? This is a big blocker for me and huge regression… I would try a fresh sdcard install but, unfortunately, at this point I don’t have much reasons to believe that it will fix my issues.

I’ve pasted my logs here: Vero4K PVR trouble - Pastebin.com

Live-stream video was playing at 50% speed, but it would occasionally skip to catch up with audio. I’m pretty sure you can reproduce it by playing the .ts file I uploaded previously.

sam_nazarko · 14 September 2021 23:29

Can you upload logs via My OSMC?

Thanks

Sam

Sorry for the delay, I wasn’t correctly subscribed to the topic. Here it is: https://paste.osmc.tv/babupiwexi

LubosD · 4 October 2021 18:13

@sam_nazarko Could you please take a look? The PVR feature remains completely broken to me.

What I find odd is that deinterlacing cannot be enabled on these interlaced DVB-S streams.

tony-r · 5 October 2021 03:06

Just for the record, I’m having a similar problem on my Vero+ with live TV from my MythTV backend. Breaks for a few seconds of black screen, every so often during the broadcast. It seems random.

Recorded TV shows from Myth are not affected. Wasn’t a problem before upgrading.

It’s not a biggie for me as I rarely use my Vero for live broadcasts.

sam_nazarko · 10 October 2021 12:44

We’ll have an update for Kodi v19.2 shortly – it would be good to check if this issue still occurs after that.

nunojsa · 18 October 2021 08:06

Hi Sam,

Unfortunately the issue is still there. I actually found something else… I disabled the video HW acceleration and the things look better but the performance is horrible though (as expected).

What I mean by “look better” is that the show duration in the OSD screen is completely wrong when HW acceleration is on (at least when timeshift is enabled) . Disabling it and the show duration time is correct and matches the EPG…

Currently I see 2 issues that hopefully are related:

Timeshift + catchup disabled and audio is out of sync with video;
Timeshift + catchup and the video just does not work (audio out of sync, video lags a lot…).

It’s starting to look that the problem might really be in the drivers which worries me a lot. Most likely you need to ask support to your vendor for this and that probably takes a time…

I’ll look in to this in more detail once v19.2 is out the door.

nunojsa · 18 October 2021 15:28

Hmm, Isn’t it already? I just did a manual check for updates yesterday and I got one… IIRC, in the system info I could see 19.2. Just asking to make sure there’s nothing else odd with my system.

fzinken · 18 October 2021 15:32

Most likely you have the development repository enabled

sam_nazarko · 18 October 2021 15:34

We haven’t got a final version ready yet.
