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: Hi, I would like to learn more in detail how a video driver works. Basically in the last days I've looked at pwc to see why it is not so robust with mplayer. I found something in the streaming ioctl calls. As an exercise I would like to port it to the "best" and "more elegant" framework, reusing as much as possible the existing v4l2 framework are writing as little code as possible (e.g. using videobuf). And remove all the v4l1 code. I would like to know which is the best USB driver to look at. Which is the best USB driver that implements videobuf? This is a good overview of a driver http://lwn.net/Articles/203924/ I think vivi.c is an other good one. Does anybody have any other good reference to look at? Thanks for your help.
