Blank status screen
Closed this issue · 3 comments
First, many thanks for this really very nice add-on to TVHeadend. It works beautifully and the Timeline display is much nicer to use than any alternative I have.
I use LibreElec as my HTPC box but could see no way of installing it there (the /var directory contents made no sense to me). It must be possible to package it as an add-on via .kodi/addons but I wouldn't know where to begin. On a Raspberry Pi (w Raspbian Stretch), however, it was trivial. Just needed to
sudo chown -R www-data:www-data /var/www/html/TVHadmin/data
The only thing not to work was the Status link. It yields a blank screen.
Checking the web server error log (/var/log/lighttpd/eror.log) yields

I searched for "simplexml_load_file" and "undefined function" and discovered that it appears that PHP7.2 or later is required (am on 7.0). Will try to fix. Meanwhile, you may want to update the requirements.
Suggestion: in the event of only a single media tag being selected it should be an automatically selected default and not need checking on the Timeline screen (I use one called Default).
Thanks for the compliments!
The issue with SimpleXML seems to be distribution-specific. The SimpleXML extension works with PHP 5 and later, and should be enabled by default. However Debian and RedHat (and maybe others) package it separately as php-xml. I use Arch so wasn't aware of the issue; I'll update the README.
Re the media tags, I'm really not happy with the way they work at the moment. I'll bear your comment in mind.
Sorry, I overlooked the option to pre-check a Tag for some screens.
My Media Tags list disappears off the side of the screen on a 1920x1200 display. A drop-down list might work better. I only use 3 bouquets of my own but quite a few are created automatically. An option to filter those might be handy (anything not beginning with "***"?) or just list starred ones first perhaps.
Timeline length: I'm using a default of 4 hours and typically look at it sometime between 6pm and 9pm. For me having the retrieval default to 6 hours with a pushbutton choice of how many hours to display on the Timeline display would be nice, if that's easily doable. It not I can live with adjusting the configuration occasionally (mainly to check on things I might want to record in the early hours).
I love the search feature!
Next suggestion: make it possible to created a list of alert terms and then a "Highlight" button to list all entries with matching text.
I like the idea of a drop-down list for media tags, it would work much better on a phone screen. I'll have a tinker...
