I would like to receive notifications on new live broadcasts of YouTube channels. As described in YouTube v3 Push Notifications I've set up a public accessible PubSubHubbub callback server and subscribed to my own YouTube channel where I've tested the callbacks for "normal videos" and for live broadcasts. The subscription returned a HTTP 204 and I am getting pings for
- new videos
- changes of videos
- deletion of vides
However I do not get a Ping when a live broadcast starts. It is visible on the YouTube channel, you can view it, use the chat, the live dashboard says everything is fine. So that part is okay. But there is no ping to the PubSubHubbub callback server for new live broadcasts.
However if I change the title or the description in the live dashboard there is a ping for the current live broadcast.
For me it looks like that there is only a "onChange" for live broadcasts, but no "created" ping. Is there anything I can do to get the missing calls for new live broadcasts?
Regards, wlami
Edit: Once I stop the live broadcast I get two update Pings once the broadcast has been processed and is shown as a video on the channel.
Youtube Notifications via PubSubHubbub states in the docs that this is meant for:
- uploads a video updates
- a video's title updates
- a video's description
No mention of new live broadcast here.
