Hi all.
Again with an em28xx USB framegrabber (brand Digitus)...

I have my v4l2 app (based on capture_example from V4L2 specs) that starts on boot. I get frames like this one:

If I restart my app manually usually all goes well. Like if... there's something wrong in the inizialization.

Does someone else got a similar problem?
Is there a good v4l2 user space library?
I'm trying to use libng (included in xawtv) but it doesn't seem easy to use actually (IMO).

Thank you in adavance.
Bye bye!

You might try:

$ hg clone http://mcentral.de/hg/~mrec/em28xx-new
$ cd em28xx-new
$ ./build.sh

.. I'll try to get that em28xx ML up again today on mcentral.de it broke when moving everything to a debian server and I didn't get around to fix it up yet.
