[libvidcap-devel] Video4Linux2 support

[Roman H. <hi...@id...>]

Hi,

recently I bought a Microsoft Webcam that was not supported by the V4L1 backend of the libvidcap library, because the driver was missing some features in the V4L1 compatibility layer.
Therefore I am working since 2 Weeks at a V4L2 backend. 

Basically it's working, but there are still lot's of missing features and lot's of unnecessary debug messages in the code.

I have tested it with two Webcams so far. The Microsoft Webcam is working, but the Quickcam Messanger at my work has a Bayer BGRG output that is not yet supported by the conversion code
(I found code in here though, but haven't checked the license yet. URL: http://home.mag.cx/messenger/ ).

Now I saw, that after a small break, there is some activity in the SVN tree again. I hope that you guys didn't already have some V4L2 code at home that is pending for a commit. 
If not, I want to discuss in what kind of way you would accept a V4L2 Backend patch to include in your library.

In the moment. I split the v4l_sapi into two separate parts, one that handles V4L1 and the other that handles V4L2. If the v4l_sapi detects that the device to open can handle the V4L2 API, the newer interface is chosen;  Otherwise the old code is used.

Would you accpet that kind of design, or would you like to have two complete seperate sapi interfaces for the two V4L APIs?
