Would you consider porting your driver to gspca, I (we ?) really want to see all usb webcam drivers start using the gspca framework to share as much code as possible. > +The ov534 outputs frames in YUYV format, non-interlaced, at 640x480. This > +format does not yet have wide support among user-land applications. Though at > +the time of this writing xawtv was known to work correctly. > + This (custom cam formats) was a big problem with gspca too, for this I've written libv4l, which is a library which does format conversion from many cam specific formats to more general formats in userspace. A joined effort between Debian, Suse and Fedora is currently working on making all v4l apps use libv4l, patches have already been written for gstreamer (cheese), pwlib (ekiga) and xawtv. For more on libv4l see: http://hansdegoede.livejournal.com/3636.html http://linuxtv.org/v4lwiki/index.php/Libv4l_Progress Maybe you can write a patch to add YUYV input support to libv4l, if you do that please base your work on the latest version which is available here: http://linuxtv.org/hg/~hgoede/v4l-dvb Regards, Hans -- video4linux-list mailing list Unsubscribe mailto:video4linux-list-request@redhat.com?subject=unsubscribe https://www.redhat.com/mailman/listinfo/video4linux-list
