UbuStream v2.1 Beta finally available

[FirstTeamOPS]

Two questions:
I have a bunch of WMP streams currently setup and all set for the internal player. I can reproduce these on any WMP stream I listen to.

1. Is the system screen saver supposed to activate when I'm playing a stream? Not the GB-PVR screen saver but the system screen saver activates after the specified time in the Display properties. That means I have no control with the remote and my system locks. Anyway to prevent the system screen saver from activating as the GB-PVR software does?

2. When the internal player starts playing after the splash screen, I see the WMP visualization. It displays fine for 10 seconds, then freezes (stops) for 2 seconds, displays for 10, freezes for 2... and it keeps repeating this. The audio continues to play with no problem there. It's the visualization that freezes. I'm wondering if anyone else is experiencing this? The CPU load is at most 2% when this happens with no spikes. I can play the same stream in WMP (outside GB-PVR) and have no problem with the full screen visualization.

Any ideas?
Otherwise, everything is working fine. Thanks.

I haven't experienced this because I have the Windows screen saver turned off on most of my computers. On my HTPC it is redundant with the GB-PVR screen saver (and I have GB-PVR running 99% of the time). On my dev machine, I have it turned off because I have known it to interfere with long ftp file transfers or Bittorrent downloads. Screen savers were originally developed to "save" your screen from burning the image into the physical display (if you left it displaying the same image for too long) back when most of us used phosphor based video display monitors. With today's display monitors they seem more like a "toy" than anything else. I seem to remember that the system screen saver will also activate if you are playing an audio stream in the native (external) WMP.

I can play the same stream in WMP (outside GB-PVR) and have no problem with the full screen visualization.

I haven't experienced this myself however I have to say that I'm not a big fan of the WMP activex component. Of all the activex controls I've used to implement the internal players, the M$ one has given me the most grief. (Very surprisingly, the RealPlayer one was the easiest to implement and pretty much worked, as advertised, right out of the box.) The impression I get is that M$ has better support for the WM player when embedded in a web page than when used in their own .Net product.

The only workarounds I can suggest is a) Use the VLC internal player instead (it only has one decent visualization but it's a good one) since it will play most wma streams or b) use Timeshift Play instead (the GB-PVR audio player uses the WM visualizations).

Maybe somebody else has a suggestion as to why this is happening. If I knew what was causing it, I'd be glad to fix it.

I'll be gone for the next three weeks so I won't be answering any posts on the UbuStream forum. (I'm going back to the "old country" - England - to visit relatives and friends. Not sure if they have the internet there. ).

So I've decided to hold off on an "official" v2.1 release until after I get back. In the meanwhile, here's the latest bugfix patch: [ATTACHMENT NOT FOUND]

Just apply it to the current Beta version from the wiki. It has fixes to most of the stuff ralphy "uncovered" since the last Beta release. Also some usability improvements (hopefully) to the internal players.

Later.

For some reason I didn't get an email notification of this post, so only loaded the patch today. Unfortunately, got a unhandled exception. Has anyone managed to install the patch successfully. I even reloaded 2.1 Beta from the Wiki again to be sure.:confused:

If I press 'continue' in the exception message, I get a new panel, showing the channel and player configuration, but 'OK' then terminates the app.

The problem might be the nulls in the player list, but when I enter some data here, the 'traditional' config still wont start.

Confirmed. I didn't get the on screen error, but the plugin doesn't load.

I thought that patch 4 might have fixed this error, but since I can't load patch 4, I figured I'd post the problem anyways..

When trying to timeshift play a dynsource video stream, I get the 'buffering' message. Since nothing seems to be happening (I think I already mentioned I am impatient!), I abort with back/esc.

Then, whenever I try to play any webstream, I get "Error: Object reference not set to an instance of object". I need to restart GBPVR to be able to use UBUStream again.

Here are the logs...

I'm back from my vacation. I'm still a bit jet-lagged but I'd like to sort out this data constraint issue. Could either or both of you send me your UbuStream.xml file so I can reproduce the problem.

Once I've figured out that problem, I'll take a look at ralphy's issue with hitting the Back button while buffering.

[ralphy]

Welcome back! Hope you had a good break.

Here's my current ubustream.xml file.

Welcome back! Hope you had a good break.

Here's my current ubustream.xml file.

Well, that xml file works just fine wth my current test system. So, either you have somehow "fixed" it (unlikely) or my Patch 4 together with the wiki version is somehow different from my current installation.

I'll put together a new "full" version when I get a moment (still dealing with stuff that's been piling up while I've been away).

On the other problem (hitting the back button while buffering), can you check that you have a valid UbuNetStreamPlayer.dll.config file in your gbpvr directory. It looks like UbuStream may not be picking up the correct StayAliveRequestInterval value.

That's the problem - no config file. Now the question is, why wasn't it present? The only thing I can think of is that when I did the install of 2.1, I chose not to install the recording service (as mentioned earlier). Of course, this meant I had to install it separately later, but it is the only obvious difference I can think of between my production system (which had no config file), and the test system (which had the config file)
