Content-Type: text/plain; charset=ISO-8859-2; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-media-owner@vger.kernel.org List-ID: Dear linux-media users, I have stopped following the advancements in Linux video (and video hw in general) a while ago, so I am no longer up to date with the current technologies, therefore I seek your advice. I am looking for for a webcam that - works properly under GNU/Linux (without proprietary drivers) - connects via USB 2.0 - can capture 720p video at 25 or 30 FPS - provides a video stream that - is hardware compressed by the camera - can be recorded to a file with minimal CPU requirements (Bonus points if it's wrapped a nice container format, so that I can simply record it by something like cat /dev/video0 > capture.mpeg - like old Hauppauge PVR-250 cards ) - can be decoded by VDPAU hw acceleration I have tried to look into this, and it seems that the status for H264 streams for UVC webcams is still problematic. However, I don't specifically need neither UVC nor H264; any driver, and any other VDPAU-supported format (like MPEG-2, VC-1, WMV9, etc) could be OK. I am not interested in sykpe; I only want to capture the 720p video stream to files (with as low CPU usage as possible), and play it back using mplayer, on NVidia cards supporting VDPAU hw acceleration - again, with as low CPU usage, as possible. Could someone please recommend me a device that can do this? (Or tell me which device will likely get the required support soon? Thank you for your help: Kristof Csillag
