Re: Subject: Composite input from OnAir Creator - use as security camera
The pvrusb2 driver does not currently support uncompressed video capture. Rather, the data arrives to the application as mpeg2. There are numerous ways to use this data. You can make it work with mplayer for example, but not when mplayer is in pure V4L mode. Rather than repeating it all here, check out the pvrusb2 web site which has a list of various apps and how to make each one work (or why it won't work). The relevant part for you should be here: http://www.isely.net/pvrusb2/usage.html#V4L -Mike On Tue, 25 May 2010, A. F.

Subject: Composite input from OnAir Creator - use as security camera
Hello, I would like to be able to capture video from a camera connected to the composite video input of an OnAir Creator.

Unfortunately, zone minder doesn't seem to be in Lenny. Months (years?) ago, I did manage to get MythTV to work with analog signals but the reception was horrible so I gave up. Watching TV is not a high priority and I never installed the amplified roof antenna. I never figured out how to select the composite or S-video inputs from within MythTV. o xawtv xawtv doesn't have a norm for NTSC (only PAL and SECAM) so even though I can select the composite input: no picture.
