Usually it's the first 1 or 2 frames from when capturing begins but I've noticed it can happen from the 10th frame. (We were trying single frame captures from the mjpeg stream, capturing 10 frames and saving the last) Either the start of the mjpeg frame was missing (I think from different offsets) or frame was truncated. The best thing we could do was to check for a valid jpeg header before saving the frame. (although sometimes the tail image data was incorrect, that was harder to diagnose without parsing the entire mjpeg frame) Assuming the drivers are correct, I suspect maybe the camera starts dumping to a frame buffer without checking for errors. We were using revision 189 of the drivers, which was fairly recent at the time. - Nick -----Original Message----- From: [EMAIL PROTECTED] on behalf of Carlos Jordão Sent: Wed 4/30/2008 6:26 AM To: [email protected] Subject: [Linux-uvc-devel] Support to a new USB Camera Hi, I'm newbie, but I have a web cam which doesn't work today either with uvc driver, either with the gspca driver. It is a Sonix webcam (SN9C110). However, I want to make it work, I don't know if it is possible. What should I do to start? Where to look out? I have looked into the code and I have seen few specifics hacks for some webcam. There is any way to identify if this webcam needs some hacks too?
