List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: video4linux-list-bounces@redhat.com Errors-To: video4linux-list-bounces@redhat.com List-ID: Hello, Although I have no experience with v4l, I find myself in the situation of having to grab frames off an old webcam. The problem is that I don't seem to have any media player that knows how to handle the adverted pixel format "O511". I seem to remember being able to use it with mplayer and v4l1 though. What do I do next? Regards, Christophe L. FYI: I am running 2.6.32 with gspca_main and gspca_ov519 loaded. The device itself is identified as: "Bus 005 Device 002: ID 05a9:a511 OmniVision Technologies, Inc. OV511+ Webcam".
