Local News M3U8 link doesn't play audio

[caseguy]

Hey all! Great work on this EPG!

Anyway, our local news , News 12, has a link that plays through every EPG program we could find, except our favorite EPG, NextPVR. 

It plays A/V through Kodi, other EPGs (like MYIptv) , VLC, you name it. When we play it through NextPVR using every decoder recommended (Microsoft or LAV) it plays with no audio. 

Here's the link- http://hls.iptv.optimum.net/news12/nipad...N12LI_WEST

Is this expected behavior for this kind of content using this program? 

NextPVR plays everything else we have, so otherwise we're in love with your program. Thank you!

If you do a recording on this channel, do you get a file on disk? Does playing this file give audio in another player?

Does NextPVR support HLS files with separate audio and video channels? That is what this m3u8 has.

It does work nicely as an extra in v5 and you can use the 720p url.

I havent tried a recording using this channel. 
Yes, using the link in another program - Kodi, MYIptv player, VLC, etc, playd audio and video as described in the original post. 

I'd love to use v5, it didnt seem functional when installing. I uninstalled it.

Yeah during normal use of this link I just plug the link into an EPG/player or VLC or used as a favorite link in Kodi and it plays. 

When posting it here it autodownloads the m3u8 file when clicked in a browser, but copy that link and plug it into NextPVR and it plays with no audio. Any other player/epg and it plays with audio. 

Is the solution just add a link in the m3u8 into the channel list in NextPVR?

[mvallevand]

NextPVR needs to chose both an audio and video URL and then have have ffmpeg sync them for proper playback.

As for the v5 not working for you it likely is something quite simple. v4 will only get basic support some I don't expect too many improvements that aren't significant bug fixes to make its way. I am very happy with how v5 is working for me.

It should, but it does this type of stream by falling back to using ffmpeg. I'll check the stream soon.

v5 was not functional for me. 
Windows 10 PC, v4 easily installs. I set it up, input my IPTV url and XML , the channels map nicely and the EPG works great. 
Using v5 - I follow the instructions, set up the NPVR server, get everything running, start NPVR and then click Devices And Settings to enter url and XML- this brings me to the http server which doesnt launch. 

When looking at the v5 post stickies, it directly states that this version isnt quite done yet. 
Changing to a broken v5 from v4 for just 2 News channel links doesn't seem reasonable until v5 is fully ready, but if you have direction as to how I can get v5 running i'd be grateful

I have taken a look at the stream, and tried a few things. It is a particularly unusual type of stream. Unfortunately I don't yet have a solution.

For my test I focused on v4, since that what you're using. I did find an fix one bug that was stopping it from falling back to using ffmpeg (instead of accessing the stream directly), but that wasn't enough to get it working. The remaining issue is that ffmpeg is very slow to start producing data for this stream, because it connects to and looks at each of the multiple separate streams, before deciding what streams to use, and in this time some other logic times out.

Ok so I got it to launch, but then another problem pops up- if I close the command window after starting the service, the entire program shuts down. 
With v4 this wasn't the case. This makes it usable on my home theater pc. 
Does v5 require the command window remain open?
