I think the iBot does DV, and I already have a miniDV cam, so I should probably diversify my devices. The writer of video1394 and some others on the devel list are using uncompressed cameras for machine vision applications, so there is work being done. There is a libdc.sourceforge.net project that provides a Digital Camera protocol library. However, there are no readily available applications that I'm aware of. I am currently working on DV grabbing and recording in conjunction with Arne Schirmacher using the OHCI DMA implementation in video1394. Eventually, I intend to marry the code of Xmovie with my video1394 capture routine to simply reflect the video transmission to a window. Xmovie uses the Xv extension in XFree86 4.0.x that utilizies the direct video playback capabilities of display adapters. (Currently, I am only aware of the Matrox G200/G400 driver that supports this feature.) I am very interested in seeing just how direct I can get from the direct memory access of OHCI to Xv! What applications are you interested in? Do you want to record to disk or videoconference over the net? I think it will be a while until we see a video conferencing application that works with 1394 cameras on Linux. I can probably hack together disk recording, but that will be a couple of months from now. Other projects are taking priority right now, I hope you understand. Perhaps someone else will beat me to the punch. +-DRD-+ > Thanks, > > Dan > > _______________________________________________ > mailing list Lin...@li... > http://lists.sourceforge.net/mailman/listinfo/linux1394-user |
