Request: Possibility to switch Audio Renderer on the fly

[imilne]

Since this is a wishlist, I'm going to sound like an ungrateful arse and ask the following... Would it be possible to have it stop the playback, apply the new renderer and restart playback without having to go back and restart from the menu? I only ask as the WAF value of pressing a single button to get sound out of the telly would be very high...!

I did think about that, but I'm not entirely sure it's possible. I'll see what I can do though...

Hmm, semi success so far.

Sub - are you reading? - if so, what's the proper way to stop a playing video?

I've tried PluginHelperFactory.GetPluginHelper().GetPlaybackProxy().Stop() but that doesn't seem to exit things properly, and any attempt to restart the video immediately after calling that doesn't give me the correct resume point (because I don't think it's been stored properly because it's not really been exited).

Weirdly, I could get it to work by doing the following:
1) restart the video while it was still playing
2) read its resume point (which got stored from the exit event generated by 1))
3) restart again, and pass it the resume point

But that seems messy. I think 1) needs to be a proper STOP (and return to menu).

That is a correct API to call. Its what I use. It will remember the resume point.

Video playback isnt automatically going to resume at the previous position though. Remember in the recordings or video library screens, if the file had previously been played, then it gives the user the option to resume (prior to starting video playback). It then starts playback of the file. If they had asked to resume, then it tells playback to skip to the resume point it had previously read.

Hmm, I must be doing something wrong then.

- I call proxy.Stop().
- The video stops, but the timeline bar remains on a black screen.

If, at this point, I resume the video, it doesn't get the correct playback position for it.

For reference, here's my resuming code, but you've OKed this before in the past.

Code:

Int32 duration = new Int32();
int position = PlaybackPositionHelper.GetPlaybackPosition(path, out duration);
PluginHelperFactory.GetPluginHelper().PlayVideoFile(path);
PluginHelperFactory.GetPluginHelper().GetPlaybackProxy().SetPosition(position);

Same thing with Live TV. If I call stop(), I just end up with the following:

I'm not really sure on that one. That is all I'm calling.

Here's a log snippet:

You can see that the PLAYBACK_STOPPED event doesn't happen until I manually intervene by pressing Escape.

I'll try to give it a shot on a different PC and see what happens there.

Exactly the same result. Me be stumped :confused:

I think I know what is happening, but I dont have an easy fix right now. I'm going to have to think about it. It might need a small interface change, which will mean it'd have to happen with the next release.

Ok, no worries. There's plenty more I can be getting on with in the meantime.

As an aside; is the process for resuming a DVD different? I haven't actually tried it yet, but I've seen references to bookmarks in the log files, and what with menus and so on, I could imagine it being different.
