Pause/play text-to-speech in Calibre viewer with Bluetooth

mrkalle · 01-04-2021, 04:24 PM

Are there any keyboard shortcuts for the text-to-speech function other than space for pausing/playing? It would be great to be able to pause/play with the buttons/touch panels on Bluetooth headphones/headsets.

What key does that generate? You can check by assigning it to some other action in the keyboards shirtcut section of the viewer preferences

Media Play

That's already implemented, see https://github.com/kovidgoyal/calibr...aloud.pyj#L191

If its not working then it means that key event is not reaching.

Media Play is mapped to Play only.
Can you make it toggle between Play and Pause?

There is MediaPlayPause for that. If your bluetooth headset has a single button, that is what it should be generating.

My Bose QC35 generates MediaPlayPause but as far as I can tell Calibre hears "Media Play". I'm on Windows 10.

sorry no clue, calibre doesnt interpret key events, that's done bg Qt WebEngine, calibre can only react to the actual events it receives.

mrkalle · 01-05-2021, 07:29 AM

How about making "Media Play" mean "Play/Pause" by default in Calibre rather than "Play"?

kovidgoyal · 01-05-2021, 07:50 AM

That would break it for people that have separate play and pause keys. The proper fix has to be in Qt, not calibre.

Thanks, I just wonder how many have separate pause and play keys as opposed to those that don't. How about if the behavior could be up to the user via a setting?

My setup is this: Windows 10 Pro x64 machine, connected to Xiaomi AirDots via Bluetooth. This earphone has only one button on each piece.

1) Using the Viewer, the button can resume playback, but can't Pause.
2) Using the Content Server Viewer (on Microsoft Edge), it can Pause and Play.

I don't know what are the events being send. But I could test it, If someone point me how. =)

CharProbe available on softpedia can tell you what keycode is generated by your headset.
My guess is that no one on Windows can play/pause using a Bluetooth headset in the viewer, only play.

Yeah like I said, its a bug in Qt WebEngine, not the calibre viewer code. it needs to be fixed there.

How about:
if ev.key is ' ' or ev.key is 'MediaPlayPause' or ev.key is 'PlayPause' or ev.key is 'Play':
self.toggle()
return

The reason I'm suggestion this is that few people have separate pause and play keys. Does anyone? Could someone who has a separate pause key for media (not the windows pause key or some other pause key) post here? Also, having the Play key toggle Play/Pause is not irrational.
