"Live TV" Black screen

[johnsonx42]

Since you have Microsoft DTV-DVD decoder available for MPEG-2, definitely try that. I just ASSumed you were running Win 10 like all the other new users around here... what version of Windows are you using? Your screenshots snippets look like Win7.

also you might try AC3Filter (http://www.ac3filter.net); MS DTV-DVD for MPEG-2 video and AC3Filter for MPEG-1 and AC3 audio is the combination I use. Sometimes it's recommended to leave the decoders for video & audio types you won't be using disabled. as far as I know with digital cable you only need MPEG2 video and AC3 Audio, maybe MPEG1 Audio (unlikely); the rest can be disabled.

Thanks! Yep, Win 7 Home Premium running WMC which is going to {{DIE}}. (I set it up on two computers early in Win7's release). I'm not going to 10 until I absolutely have to but want to be proactive, have a working alternative before getting the 10 "upgrade". Almost a year to make the change with a free upgrade and maybe a couple of years or so beyond that before WMC is dead. For example, MS is pulling the plug on the WMC Netflix extension next month so shortly I'll have to adjust not having a single remote to access everything I use. WMC really is an elegant program, so sorry to lose it.

JUST NOW I just made the adjustments you suggested in settings and WOW!!! Channels are now changing VERY QUICKLY!!! YAY!! THANKS SO MUCH!! But... what happens when I go to ten?? I'm using MS and its codecs as my backend which doesn't exist on 10, right??

I'll start playing around with the AC3 filter tomorrow when I'm not cross-eyed from trying to figure this stuff out. And btw, I didn't get an email alerting me of your last post. Just happened to find it when I was trying to re-read and figure out the AC3 filter stuff. Then I need to face the prospect of trying to get the epg working... then the remote... and maybe then try to integrate NextPVR into Kodi so it can work from one UI.. Is that even possible?

Great!

The LAV audio decoders are great, but the LAV video decoders are quirky when used with live digital streams. While the MS decoder isn't available on Win10, there is lots of other MPEG2 decoders that work well (from Cyberlink, MainConcept, ArcSoft etc). Annoyingly most of these are not freely downloadable, and I'm not big on recommending codec packs (since I don't know what malware they might come with). Most people get these other decoders by way of other software they have installed on their machine, like manufacturer's software that came with the tuner.

SAF is a bundle of software programs and decoders that will will work with any TV service anywhere in the known universe. SAF includes an installer and will install the software and decoders and will configure NextPVR to use the most appropriate decoders.

The "unlocked" version of SAF includes decoders that are not included in the default download. You can send Hoborg a forum private message on this forum (i.e. the NextPVR forum) to get the unlocked version.

Thanks! I've sent the PM to Hoborg. Seems I would need to get NextPVR working properly without needing the Windows codecs I currently have on my Win7 installation. After I downloaded/installed the full (and as I learned later, locked) version of SAF I found that their player was added. "Media Player Classic - Home Cinema". Since it's taken possession of a lot of file types, in retrospect I assume only the codecs should have been installed?

if i can make a suggestion (from the user's perspective) nextpvr needs improvements in live tv graph creation. I remember good channel change times only with windows 7 and ms decoder. the change to windows 8 and now windows 10 leaves nextpvr (client) almost unusable. i'm forced to use kodi with nextpvr.
Also noticed that the graph loads many filters not needed, and don't know if this the cause of the slugginesh of the client.
This is a real pity because the server part is a great piece of software.
Bye,

I'm happy to take a look at your logs if you're having problems.

I don't think your problems will be around the filters that are loaded. It only loads what you could potentially require. ie, a video decoder, plus whatever audio decoders you've enabled. If you don't need some audio decoder, then you can set those audio decoders to 'disabled'. It loads all the audio decoders you've enabled, because it doesn't know what audio you're going to encounter later in that live tv session, so needs to be ready to change to a different decoder on the fly. If it didn't do this, then you'd add several seconds to each channel change (as it'd have to destroy and recreate the graph on each channel change).

Ok sub, thank you for your interest, will post logs when i'll return from summer holidays.
Regarding filters, i don't know how nextpvr is programmed, mine was only an assumption, related to several audio filters loaded, and compared to other software that builds the graph only with needed filters (retaining very good channel change speeds).
Anyway I think there's something you can improve in the code, because nextpvr is heavily dependent on the codec used. Some codec block nexpvr for 10-15 seconds on a channel change.
Will post you logs with different codec configurations.
I've noticed that others have the same problem (especially with lav filters decoding mpeg-2).
Thank you,

The LAV decoders are definitely problematic for video, and should be avoided. They don't play nicely with the Microsoft demultiplexer, which is used by NextPVR. Other video decoders perform much better. At the end of the day, I didn't write these decoders, so I've really got no say over how well they perform. The LAV decoder seems great for audio, but sucky for video.

Most people have a channel change time between 1 second and 4 seconds with NextPVR. There is no reason you should have to live with 10-15 second channel changes.
