`kivy.core.audio` - SoundLoader: support URLs as source, error handling and timeout about kivy

[az75014]

The issue with pause/play causing the audio to go to the timestamp specified by seek(position) and then restart from the beginning may have to do with the play method having an extra step of seek(0) at the end? I can't quite figure out why this step is there. If you use ffpyplayer directly the toggle_pause() method works exactly like you expect -- as a toggle, there is no need to play around with seek() at all as it remembers the time stamp.

EDIT: If in my own code I build in a delay (e.g. via Clock.schedule_once) between play and seek(position) by triggering the seek() via the callback then it works fine -- I guess timing issues are causing the extra "seek(0)" to fall after my own code is doing seek(position)? Seems like a bug to me?

Code snippet from audio_ffpyplayer.py:

    def play(self):
        if self._state == 'playing':
            super(SoundFFPy, self).play()
            return
        if not self._ffplayer:
            self.load()
        self._ffplayer.toggle_pause()
        self._state = 'playing'
        self.state = 'play'
        super(SoundFFPy, self).play()
        self.seek(0)
