Controls in Google Home App

[vanadinit]

Hello everyone,

I am searching for a possibility to control start/stop/pause/seek via the Google Home App after invoking the video stream via pychromecast.

My actual setup:

• local video files at my PC
• serving video file via a HTTP Server to have a streaming URL
• discovering and selecting chromecast via pychromecast
• giving URL to cast.play_media to start casting

Interestingly appears the play/pause button, if I have the Google Home App open on my smartphone when starting to cast. If I open the app later on or reopen it after a while the button is missing. The seek bar for jumping in time is always missing (but I know it from casting from several apps, Youtube, ...).

Any idea how to get these controls? Is there a specific information or format needed?
