However libdc1394 http://sourceforge.net/projects/libdc1394/ has a small utility called dc1394_vloopback. You can use this to send a 1394 device (camera) to a v4l pipe. You also need vloopback which is a kernel module. Hence you need to have kernel source included in your instalation. A good tutorial on using vloopback can be found at http://veejay.sourceforge.net. vloopback is somewhat orphaned and I recomend you use the hack from http://tibit.org/video/index.html Once you get these there is no do man page for dc1394_vloopback. Usage is as follows: dc1394_vloopback --v4l_dev=/dev/video2 (Assuming you have a capture card allready using /dev/video0) Then in mp4live you specify the input as /dev/video3 (the output of the pipe) Unfortunately you may have to use the normal resolution of the camera which is likely to be 640x480. Not much fun for streaming. This is also a good way to use xawtv to record from your 1394 device. > > I think all that mp4live needs is video4linux, there is video4linux > support for firewire in Redhat, right? Only rudimentary card support. Get everything you need from the links section of http://www.linux1394.org/ They have a very good getting started section. > > mp4live runs here nicenst, on an old PII 233 Mhz with 176x144 15 fps and > 8000 b/sec aac audio, with Redhat 9. dc1394_vloopback is sort of cpu intensive. I think it's going to be beyond slow on that machine. Good Luck Daniel Jircik
