			Made final improvements on the merge request. There were a number of small things that shouldn't be there (forgotten from early work). The objectives were completed, in my opinion. It was a great SoC :D

			Improved the previous work and implemented alsa capture. From the Phonon and Phonon-VLC point of view, it works correctly. However, unfortunately, although VLC sais it has opened the device without problems (both when used from Phonon-VLC or when used normally), but no sound is captured. arecord works fine. I attempted to investigate in VLC's sources and arecord's sources but they are too complex to give me an idea about what happens.

			Basically, the work for Phonon and Phonon-VLC regarding capture is completed, I will update the merge request soon. But this no sound issue remains. I need to test this on another system and investigate more deeply.

	Finished work on AVCapture, but is not of any practical use until audio capture is functional. Now I'm thinking about audio capture. Part of the work implied improvements for the merge request to preserve ABI for Experimental as much as possible. The merge request will be updated soon. I also need to think more about whether to keep v4l2devices.h/cpp or to rename it and include searching for other classes of devices.

			=== August 2 ===
			During the last week I spent more time than expected on setting up development stuff on the new system. At least it compiles 10x faster than the old one. One day was for installing and configuring the OS, one day for copying and compiling phonon and phonon-vlc, one day for doing battle with vlc/extras/contrib, one day with kde trunk trouble, one day for issues regarding phonon + kde + pulse + undefined symbol stuff. I also compiled pulseaudio. One day I was too tired from these issues and now I finally started with ALSA capture. The device list for these is in kaudiodevicelist, in kdebase/runtime/phonon, and it has something to do with the platform plugin, which is currently unexplored "territory".

			I managed to do some improvements on my work in Phonon-VLC. Ugly looking v4l2 stuff are now only in devicescan.h/cpp.

			Currently I need to figure out exactly how this Phonon platform plugin works and use it for ALSA devices in Phonon-VLC.

			=== July 19 ===
			Now working on the AVCapture class. I have made a simple implementation in Phonon-VLC, and now I am testing and fixing errors and omissions. Ideally, it will be tested at the same time with audio capture. There were some delays induced by me trying to package libglew for Ubuntu on the buildservice by myself :(, and an evil illusive typo :( . Despite this, I am feeling confident.

Options are:		I have documented most of the Phonon-VLC code with Doxygen. I've gained good understanding about how the whole Phonon system works. Previously I was planning to work on AVCapture, but I found out that I had insufficient knowledge about Phonon and Phonon-VLC to do it. That is why I did the documentation stuff.

			Now I need to decide on what to work next and start working on it. Options are:
	* Test audio capture / audio data output, fix any issues		* Test audio capture / audio data output, fix any issues
	* Work on the AVCapture class and implement AVCaptureInterface in Phonon-VLC		* Work on the AVCapture class and implement AVCaptureInterface in Phonon-VLC
