dv4l for Debian --------------- - DV4Linux - Limitations (Copy from: http://dv4l.berlios.de/limits.html) - dv4lstart dv4lstart has currently these limitations: * The V4L application must not be statically linked to libc, or have the 's' (set user/group ID on execution) bit enabled. * Only RGB24 and YUV420P palettes are supported. * dv4lstart does not support adjustment of color, brightness and similar parameters. * Using dv4lstart adds a little overhead to all library calls that are used in the V4L API. * It supports only a single dv1394 camera. - dv4l Currently, dv4l has some limitations: * Only RGB24 and YUV420P palettes are supported. * Not all v4l programs work with dv4l. Skype v2.0beta seems to have trouble with the vloopback driver. GQCam, Kopete, and probably others work only in a slow mode where the video frames are copied twice. * dv4l does not support adjustment of color, brightness and similar parameters. * Using dv4l is inherently slower than using other methods to access a camera. * It supports only a single dv1394 camera. - dv4l or dv4lstart? dv4l requires the vloopback kernel module. dv4lstart add a little overhead to every library call that might be used to access V4L. Applications using unusual ways to access the V4L API might not work. skype (2.0.0.27 beta) runs only with dv4lstart Other programs can be used with any of dv4l and dv4lstart. - How to test dv4l (use effectv) 1. install vloopback kernel module and effectv # apt-get update ; apt-get install vloopback-source effectv # m-a a-i vloopback 2. Connect DVcam to your PC 3. sudo dv4lstart effectv - How to use dv4l on ustream 1. install vloopback kernel module, iceweasel and flashplugin-nonfree # apt-get update ; apt-get install vloopback-source iceweasel flashplugin-nonfree # m-a a-i vloopback 2. Connect DVcam to your PC 3. Start iceweasel with dv4lstart # sudo dv4lstart iceweasel 4. Connect to ustream -- Nobuhiro Iwamatsu Sun, 26 Oct 2008 18:38:20 +0900
