Getting the VBI data

[red_f]

Is there anyone around that has succeeded in getting the VBI data into a GBPVR plugin?

Why?

Final goal: create a plugin that supports PDC (Programme Delivery Control) to start/stop recordings.

But first I want to create a very simple plugin that can log the VBI data as it appears on the selected tuner/channel combination.

The 'very simple plugin' part wasn't that hard , getting the VBI data, however, is. So my question is whether anybody has some pointers for me.

My previous experience on using DirectShow was while writing capture tuner card device drivers where we were using C++ on the DirectShow API (and Kernel API). I have been writing lots of C# since, but DirectShow support for managed code is scarce to say the least. Apart from that I would rather use any API supported by GBPVR than reverting to rough Directshow.

All help is appreciated!

Sorry, but I dont think there is anyway you could get this info in a plugin, not with replacing all the existing tv tuner card usage with your own code. Its not possible for plugins to access the directshow graphs used by GB-PVR.

Yeah Sub,

that was exactly what i feared. No way for you to add a kind of delegate or event to the existing assemblies/classes that we could use for this kind of purpose? Kind of like subclassed Teletext or something?

Are you using the raw vbi data for teletext support or only the TT parts? There are actually lots of cool things hidden in the VBI data here in Europe (PDC, Nextview EPG).

And I *really* wouldn't like to go through the hassle of constructing graphs for every supported card. Did parts of the BTWinCap driver code for BT8x8 TV-cards and I know the feeling when card X should do _this_ but only does _that_ wich is exactly opposite of the documentation. At the age of 47 I start feeling like 'been there done that'

Still it would be great to be able to get to the VBI data to chip out information like PDC.

And of course thanks for taking the time to reply.

I'd like to say yes, but to be honest it sounds like a lot of work and I've got my hands pretty full with other stuff at the moment. I can also tell that if you could get this info, there would be many other requests following as you find you want to interact with GB-PVR based on that data. Unfortunately, this all requires time I dont have available.

I understand, and GBPVR is in good (commercial) company: Windows MCE (SDK) also lacks solid support for this (and the related control).

Have fun with the family.
