I have written a better EPG

I'm sorry but I know this has been covered in various ways when discussing apps, but I don't think it's been specifically discussed about the web interface t...

Thanks for reply, have had time to do as suggested...

now have this:

/usr/lib/cgi-bin/tvh_epg.py in <module>()
1613 cgitb.enable(display=0, logdir=DOCROOT + '/python_errors', format='html')
1614
=> 1615 web_interface()
1616
1617 else:
web_interface = <function web_interface>
/usr/lib/cgi-bin/tvh_epg.py in web_interface()
1548 html_page_footer()
1549 elif p_page == 'error':
=> 1550 html_page_header()
1551 page_error(error_text)
1552 html_page_footer()
global html_page_header = <function html_page_header>
/usr/lib/cgi-bin/tvh_epg.py in html_page_header()
1332
1333 bg_col_page = BG_COL_DEF_PAGE
=> 1334 if BG_COL_PAGE in MY_SETTINGS[SETTINGS_SECTION] and MY_SETTINGS.get(SETTINGS_SECTION, BG_COL_PAGE) != '':
1335 bg_col_page = MY_SETTINGS.get(SETTINGS_SECTION, BG_COL_PAGE)
1336
global BG_COL_PAGE = 'bg_col_page', global MY_SETTINGS = <configparser.ConfigParser object>, global SETTINGS_SECTION = 'user', MY_SETTINGS.get = <bound method RawConfigParser.get of <configparser.ConfigParser object>>
/usr/lib/python3.6/configparser.py ingetitem__(self=<configparser.ConfigParser object>, key='user')
957 defgetitem__(self, key):
958 if key != self.default_section and not self.has_section(key):
=> 959 raise KeyError(key)
960 return self._proxies[key]
961

builtin KeyError = <class 'KeyError'>, key = 'user'

I don't have any initiation of setting up a "settings file"; when I tried to create a user with persistent authentication in the TVH "users" page; there is no "persistent authentication token" read only field. Perhaps my TVH version is too old/outdated (v HTS Tvheadend 4.2.8-36~g5bdcfd8ac) ??

Hi,

did you make the directory /var/lib/tvh_epg/

and make it group www-data and group writable? (or whatever httpd runs as)

that should allow you to go into the settings menu and set the values to your local services. the EPG cgi-bin doesn't need to run on the same server as TVH, which might be a good thing if you're running TVH on a low powered device like a Pi.

with the help of "dgilbert2" on github, I have made some big improvements to my tvh_epg.py program.

* CSS fixes so the layout works better across platforms
* tooltips work, showing additional program detail if available
* code to avoid broken picons

for those stumbling across this discussion, the repository is here: https://github.com/speculatrix/tvh_epg

Last nights latest w3c updates have broken a couple of my TV logos, screenshot below;

https://i.postimg.cc/ZncgR9gV/Broken-TV-Logos.png

Its looking for picon That's%20Music.png but the file itself is That's Music.png. What should the file name actually be?

Paul M

Hi,
I'll take a look. I haven't updated my picon set for a while, so I'll do that and test it.

David G

I've done some digging and the issue seems to be the coding for the ' character used in "That's".

The picon URL name in tvh_epg therefore needs to be changed to;

That%27s%20Music.png

Hope that helps?

David G

I may have just found a fix?

Around line 89 I did this (&rsquo #'d out and added the %27 line);


INPUT_FORM_ESCAPE_TABLE = {
    '"': "&quot;",
####"'": "&rsquo;",
    "&": "&amp;",
}

URL_ESCAPE_TABLE = {
    " ": "%20",
    "'": "%27",
}

DaveH

Something's not quite right there. ' doesn't need to be escaped in a URL, and neither ' nor space need to be escaped in a filename, at least on linux and friends. So whilst it might make things work, it doesn't smell right.

David G

I see what you mean, the %27 and %20 lines aren't needed for it to work. Its the &rsquo line that just needs to be #'d. One for Paul to look at ;-)

Paul M

I updated my picons from git but for freesat in the UK, I don't get a "That's Music.png" file.

I don't have any logo files with a single or double quote, so I only got to test with an ampersand, but I will look at how I am using the URL_ESCAPE_TABLE to make sure I am doing it right. The code needs tidying up as there's too much identical code between page_epg and page_channels anyway.

Paul M

p.s. I am happy to accept pull requests or diff/patches.

David G

Hi Paul M, to try and help I've attached Freesat channels 91 & 92 TV logos.

To keep things simple, I would just # out this line for now, at least things seem to work then on my setup?;


#   "'": "&rsquo;"

EDIT: Note the forum has changed the ' character to _ in logo file names so needs a rename ;-)

Paul M

I added a channel table feature which is much more convenient than having a list; the number of columns in the channel table is user-settable.

I also combined the channel list and epg function.

happy to receive ideas

Paul M

I added your fix, DavidG, for channels with apostrophes in the name

David G

All good, thanks Paul M.

Paul M

realised I'd created a few bugs because I was improving the score in pylint, fixed those. I think I'll stop that for the moment and try and do them all in one go and test better before pushing.

I enabled the discussions feature in github.

Big thanks a lot easier to use than the installed version

Your thanks are much appreciated. And I'm happy to take ideas and contributions.

TVHAdmin works great on my system (Debian). However I have one annoyance. When I start a stream with TVHAdmin it is nicely forwarded to VLCPlayer on my system. However each time I also have to manually input my user-credentials of TVHeadEnd again in VLCPlayer otherwise it will not start the stream. When using the UI of TVHeadEnd itself this is not needed, thus there these seems implicitly included in the URL. What can I check/do to solve this. I have the feeling that TVHAdmin does not include the user-credentials in the URL.

I am running the latest version of TVHAdmin and TVHeadEnd (4.3-2098~g44bf691ac). I use as browser Firefox, but have the same issue with Chrome.

When you start a stream, with TVHadmin or the TVH UI, a .m3u file is downloaded which your browser then passes to your player to open. The URL in the file from the TVH UI includes a 'ticket' parameter which links to your user credentials, the one from TVHadmin does not.

The quick workaround is to remove the need for authentication when streaming, by giving the "*" user basic streaming rights. I'll check where the 'ticket' comes from, and if it might be possible for TVHadmin to supply one.
