I can get vision with raspivid but it's cropped and stretched (think a 640x480 crop and then stretched to 1920x1080). [..]
That's using firmware mode. I would also try
Code: Select all
$ mplayer tv:// -tv driver=v4l2:device=/dev/video0:width=1280:height=720:fps=30:outfmt=yuy2
(with a source which offers that resolution/framerate), and the examples in this section: https://fluxcoil.net/hardwarerelated/ra ... mbinations

With switching to kernel mode, that's expected - based on other comments in this thread and what I see with my setup.

I'm not aware of any, and it would also need to cover multiple boards - I guess many just got one. I have my pieces on the page linked above. I get lower latency in firmware mode, but can also record/gram in kernel driver mode.
Wiki pages seem like a good format for documenting "a current state", and then having them indexed by search engines. This thread is great and helpful, but from format one can read it completely through, and has along the way also captured information which is no longer valid.
I think the camera docs part of the raspberry wiki currently does not refer to kernel mode, that could be a nice extension.

I have a different board, but I'm surprised that the vendors do not care more about documenting their pieces for what the customers want to use it with. Maybe they just aim at industrial customers who buy thousands, and have their engineers talk directly?
In my case, audio grabbing is not yet working. I was able to reach the Chinese vendor of the board I got, and was informed that "Audio was not tested, but with connecting 4 pins it should work". (Need now to get hardware from Akihabara to test it.)
So while not easy, one can reach the vendors.
