Channel groups, and client crash with empty group

[ctrlbrk]

I'm new to nextpvr, coming from tvh.

My full IPTV m3u has like 30k URLs and over 100 groupings.

I need a few channels from a few groups only, like less than 50 channels total.

I am used to creating a custom channel group in tvh for this -- one for me, one for my wife -- so we only see what we want.

When I went to nvr settings -> channels -> + to create new group 'Mike' and then I tried to put some channels into it -- but it doesn't submit my changes.  When I leave and come back, the channels are no longer in the group.

Also, it appears the Android client flat out crashes when there is an empty channel group.  It was working fine, and my only change was creating the 'Mike' group above.  Now the Android client crashes, you can tell it is hanging on the Channel Group selection.


logs from docker:

wow, the bbcode for "code" is broken it seems, throwing a lot of broken html/bbcode.  I'll just plain-text post:

x.y.z is my public facing port-forwarded URL.

I submitted the Android crash reports to you, but if there is another way to see logs on Android let me know.

Interestingly, I deleted the empty group on the server, and the client continues to crash, but with a different log:

So is there a way to group just a handful of selected channels into my own created group? Is what I described in my first post supposed to work or am I using it wrong?

Otherwise, I could just write some code and proxy my M3U url with nginx/php and do it myself, but it's certainly just a patch job if I do that and a lot harder to maintain.

My full IPTV m3u has like 30k URLs and over 100 groupings.

I need a few channels from a few groups only, like less than 50 channels total.

The best starting point, is while importing, filter select only the groups that'll contain the channels you're interested. ie, "USA HD" or "UK HD" or whatever. Things will be much more responsive if you're not trying to work with 30k channels.

After this, yes you can go and create whatever groups etc you want.

If the groups interface isn't working, it maybe something to do with database performance with having 30k channels...so delete all the channels, then try filtering to only the subset at import time, then try the group creation again. If it's still not working, I'll take a look for you.

Actually that picture was from a digital tuner, but it's pretty much the same for IPTV.
