API to disable / enable an autorec?

[mathieugouin]

Hello!

First thanks a lot for this wonderful doc of the tvheadend API.

I was curious if you know of a way via API to disable and enable an autorec?

I'm asking because I realized that once scheduled, tvheadend does update timer derived from autorecs if the xmltv is later updated. My idea was to disable, the re-enable all autorecs timer to force tvheadend to "update" them with the latest xmltv EPG.

Thanks in advance!

Changing the enable flag on an autorec should be possible using the idnode API but I doubt that it would achieve what you are asking. As far as I am aware, an autorec simply creates timers for matching events. You could delete the autorec (which would delete all pending timers) then re-create it, but that would be rather drastic. Tvheadend does update timers from the on-air EPG, I'm surprised that it doesn't do the same from XMLTV.

When I use the web UI for thvheadend (ex: http://IP_ADDRESS:9981/extjs.html), and I go to the autorec tab, I can perform the disable / enable from there. Actually, I have to disable, save, enable, save. By doing so, from what I understand, it forces tvheadend to re-create the matching EPG entries to the autorecs.

I'm surprised that the on-air EPG triggers update of the timer entries? I was never able to make it work with XMLTV :( Where I live, the on-air EPG is not usable (some channels don't populate it).

My setup is as follows (maybe you can see something):

• I use a script to download nightly 14 days worth of EPG from an online source. I use local caching to not stress the server.
• Only the next 3 days are always updated (no cache).
• My xmltv file is generated from this.

From what I saw, as soon as a new EPG entries is added in the XMLTV (14 days in the future), a new timer entries is created and never updated if the EPG changes down the road.

Thanks again, I will try the idnode api as you mention and let you know how it works.

Wow it works like a charm!

If it can help someone, here is my quick python script to do it:

#!/usr/bin/python3

import json
import requests
import urllib
import time

TVH_SERVER = 'http://192.168.1.23:9981'

def get_api_url(api):
    url = TVH_SERVER + '/api/' + api
    ts_response = requests.get(url)
    if ts_response.status_code != 200:
        print('Error code %d\n%s' % (ts_response.status_code, ts_response.content))
        return {}
    ts_json = json.loads(ts_response.text, strict=False)
    return ts_json

def get_autorecs():
    return get_api_url('dvr/autorec/grid')

def get_idnode(uuid):
    return get_api_url('idnode/load?uuid=' + uuid)

def set_autorec_enabled(uuid, enabled):
    js = {
        'uuid' : uuid,
        'enabled' : enabled
    }
    api = 'idnode/save?node=' + urllib.parse.quote(json.dumps(js))
    #print(api)
    return get_api_url(api)

def json_pp(js):
    print(json.dumps(js, indent=4, sort_keys=False))

def main():
    autorecs = get_autorecs()
    #json_pp(autorecs)

    enabled_uuid = []

    if autorecs and 'entries' in autorecs:
        for e in autorecs['entries']:
            if e['enabled']:
                #print("%s\t%s\t%s" % (e['uuid'], e['enabled'], e['name']))
                uuid = e['uuid']
                enabled_uuid.append(uuid)
                # disable
                set_autorec_enabled(uuid, False)

    time.sleep(3)

    for uuid in enabled_uuid:
        print("Enabling " + uuid)
        set_autorec_enabled(uuid, True)

if __name__ == "__main__":
    main()

Excellent, glad you could make it work.
