I know the deps are the wrong way around, but no-one can use a plugin on its own so no worries there, and this will mean that all the plugins are installed to begin with, and all but one can be removed without any dpkg problems.
Providing a splash screen telling the user how to install the plugins does not seem user friendly at all to me. Especially since the application manager is slow when installing multiple packages by hand.

I've just pushed all packages to the autobuilder now. Hopefully I've got the dependencies right. I had to remove deps on mbarcode from all the plugins in mbarcode-plugins-all to avoid dpkg -i crashing on circular deps.

Just a quick status update, I've got PythonQT compiling. Now I need to package it up and push it to the repo and then we can look at how to use it to let us have Python plugins as well as C++.

I have tried to use mbarcode to decode the QR codes shown at http://www.qrcomic.com/. I traced the problem to the small size of the pictures used by mbarcode (400x240), which doesn't allow a large enough resolution to scan e.g., a 175x175 dots QR code. Is 400x240 a hardware limitation? Or would it be possible to use e.g. 800x480?
Besides, I'm eagerly waiting for python plugins!

I just tried the link you gave and other than needing to hold the N900 quite a long way back (as the barcode that was displayed was rather large on my monitor) it all seemed to work fine.
I did a rough count, and the barcode I scanned was only something like 60x60 elements (probably 64, though I've not checked the QR spec recently to see what the required sizes are), which should be easy to decode.
Also, iirc internally mBarcode uses a frame size of 640x480 on the N900 and this size of frame should also be saved in the history list/exported to file (though if it's not, please let me know and I'll check). The thumbnail that is actually presented to the user is smaller afaicr.
I'll try to get PythonQT packaged up this evening when I have a few minutes spare

I'm running it on a N900. I saved a picture shot by mbarcode, and the Pictures application in Maemo claims its size is 400x240. These are also the values of N900_WIDTH and N900_HEIGHT in mbarcode-qt/common.h.
The picture changed since I posted the link. Try http://http://www.qrcomic.com/39 and let me know if it works (zbar is able to decode it, this I tried already).

I see the problem. No, I'm not able to decode it either. I wonder if there's a way around this? Basically using full-frame data is slow for the decoder, also altering caps in the pipeline requires that it is paused which is obvious to the user. I wonder if pulling higher res data from the pipeline and then either sub-sampling it in my decoder threads or asking the decoders to do this themselves normally would be a decent trade off of normal speed vs the ability to look at the high res data if nothing can be detected.
I'll see what I can do, thanks for bring it up.

- mbarcode depends on mbarcode-all-plugins or mbarcode-plugin
- mbarcode-all-plugins depends on the core plugins
- mbarcode-plugin is a virtual debian package which is named as Provides: mbarcode-plugin in all the other packages?
I'll try to set this up now and revert the changes in SVN.
