One Stream at a Time?

[crackulator]

Ubuntu client, 5.0.0.191007 and HDHomeRun, I can only run one live stream at a time.

Clients are Linux/NextPVR/Knewc and Chrome/NPVR Android Addon. I can run a live stream on either one alone, but when I try to run both, when I start the second, everything looks fine but video doesn't play. I can play one live channel and one recording, but not two live channels. Doesn't seem to matter if it's the same channel or different channels.

Log attached.

Going by the logs it looks like you left the browser on a failed play on 192.168.254.55 (the same PC running knewc) when you restarted the server which causes all kinds of transcode.status message error to be logged to a default sid and weird behaviour. You need to shut down that browser session and try your test again.

I meant to write that up for sub, it happens enough to be annoying. You don't have the start of the error in your 4 logs.

I will rerun it tonight and update.

Ubuntu client, 5.0.0.191007 and HDHomeRun, I can only run one live stream at a time.

The web app currently only gives one stream per session. If you open a second tab, it's still the same session (so starting playback in the second tab will stop the first). You can open an incognito/private browser to login again and get a second session. Or use a second machine, or a different type of client etc.

Attached is a new log of the same condition, but after closing the hung browser tab noted above.

Neither of the clients I'm using (intentionally) are in the browser, they are Chrome/NPVR and Linux/Kodi/Knewc, on two different machines, both separate from the server. Though Knewc might look like a web session to the server, I dunno.

I also tried it with two Linux/Kodi/Knewc's on the same machine (but different from the server), same result.

I just did the same test with the Kodi NextPVR PVR addon, same result. Both kodis running on same Linux machine.

I can stream on either instance, but if one is streaming and I try the other, I get no video.

Did you try a test from two different tuners?  I know that multirec is not working very well for me in v5 yet.   

Also since the one test you showed was IPTV the issue might be trying related to how many instances you allow for that provider or how sub uses the client parameter for IPTV

Code:

2019-10-10 04:56:13.200    [DEBUG][18]    /live?channel=6&client=sdl-KNEW50x782bcbacacf4&sid=3e241a74338a4a8caff43f59955106de

The issue with the browser was a Firefox user agent.

2019-10-10 04:50:12.620 [DEBUG][6]   user_agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:69.0) Gecko/20100101 Firefox/69.0

The unique client ID for knewc is the MAC address so two instances on the same machine will not be unique.  In theory this would mean the second attempt would close  playback on the first client. It may also cause problems because there are two SIDs for one client ID.

All these tests are all on the 3-tuner HDHomeRun.

There should have been no IPTV involved. The only IPTV in the system is on the v5 server, it has an IPTV virtual device by default, but I've never tried to use it, and it has no channels. Seems like the client query would probably query that and find nothing, but it shouldn't try to stream it. ??

What's wrong with the Firefox user agent?

Sounds like the issue of simultaneous streaming is complicated, some scenarios should work and some not... not sure about the ones I presented, seems like most of them should. I'd like to stream two knewc's on one Linux client, so would be disappointed if that is not possible.

Must be the way v5 logs, it looked like IPTV to me and I didn't see an HDHR playback attempt.

Code:

2019-10-10 04:56:13.223 [DEBUG][18] checking: IPTV (http://...)
2019-10-10 04:56:13.223 [DEBUG][18] enabled and present

2019-10-10 04:56:13.228 [DEBUG][18] live tv is not possible

There is nothing wrong with FF user agent, I was just saying that is what is logged and why I said it was a browser playback error nothing to do with knewc or Android.  From Kodi it would be Kodi or python in the user agent.

I regularly test streaming multiple streams using the /live?channel= API without issues so it should be possible (at least when not transcoding)  Here are my three tuners

The second log (in message #5) shouldn't have any browser activity (at least, unless I forgot a tab somewhere). The two clients are Chrome/Android NPVR on a laptop and Linux/Kodi/Knewc on a desktop (both different from the server). This seems like a case that we expect to work.

The other two cases I reported look like the same error, but they might be explained by appearing to be the same session, because they were both the same client software on the same machine (one was Knewc/Knewc, one was Kodi-NextPVR/Kodi-NextPVR, on the same Linux machine). In any case none of them exhibited the described intended behavior (old stream stops and new one starts), the newer instance just didn't work, without any apparent explanation.

This seems like a less common use-case but for myself, I would like "the Linux box running multiple instances of kodi with knewc" to work.
