[ST Edge] mediaPlayback - issue with fastForward command

Hi,

I’m trying to create a virtual audio device with mediaPlayback capability.
The capabilities are registered as follows

capability_handlers = {
 ...
             [st_capabilities.mediaPlayback.ID] = {
                [st_capabilities.mediaPlayback.commands.play.NAME] = event_handler_media_playback_set,
                [st_capabilities.mediaPlayback.commands.pause.NAME] = event_handler_media_playback_set,
                [st_capabilities.mediaPlayback.commands.stop.NAME] = event_handler_media_playback_set,
                [st_capabilities.mediaPlayback.commands.fastForward.NAME] = event_handler_media_playback_set,
                [st_capabilities.mediaPlayback.commands.rewind.NAME] = event_handler_media_playback_set
            },
}

When the driver is initialized, it prints

CapabilityCommandDispatcher: Virtual Devices Creator
  default_handlers:
...
    mediaPlayback:
      play
      fastForward
      stop
      pause
      rewind

I receive events for all commands, except fastForward.
When pressing fast forward button, I immediately get ‘A network or server error occurred’ . I don’t see any events generated in the log.
What am I missing?
Thanks

P.S.
The handler looks like this, but it is never called for fastForward, so I don’t think it really matters

local function event_handler_media_playback_set(driver, device, event)
    local cap = st_capabilities.mediaPlayback
    local ev =  event.command == cap.commands.play.NAME  and cap.playbackStatus.playing() or
                event.command == cap.commands.pause.NAME and cap.playbackStatus.paused() or
                event.command == cap.commands.stop.NAME and cap.playbackStatus.stopped() or
                event.command == cap.commands.fastForward.NAME and cap.playbackStatus.fastForwarding() or
                event.command == cap.commands.rewind.NAME and cap.playbackStatus.rewinding()
    device:emit_event(ev)
end

Hi, @ygerlovin.
This issue is already reported, it is not related to the driver but the capability itself. I already shared your comments in the corresponding report to see if there’s an update about the progress.
As soon as I get more info, I’ll let you know.

Not only is the mediaPlayback fastfoward control not working, but now none of them are… on iOS anyway…

I know this is a ‘proposed’ capability, so I’m not optimistic it will be fixed anytime soon.
