Streaming DV Video in Fedora

[Guest]

Hi,

I would like to stream some video coming from a video-firewire converter in Fedora and compress it in one of the MPEG4 codecs available.

I have verified video on the firewire port by using Kino and the /dev/raw1394 device. When I use this device in VLC I don't get any video input. When reading http://www.linux1394.org/video1394.php they sound like I have to make a pipe from the firewire port to the video4linux device. Is this correct? Do you guys have any advice that can lead me in the right direction to get started?

Okay, I just read on another forum for Kino that this isn't possible. Is this correct?

Thanks,

Brad

currently the only solution is to use something like dvgrap to get the stream from the camera, and then pipe it to vlc. Supporting direct grabbing from dv camera shouldn't be hard, but none of the developers have the necessary hardware to code it.

Do you know how to build a pipe to do this? I have the theory at hand, just don't now how to do it.

Thanks,

dvgrab |vlc -

put any parameters to dvgrab in between.

Got a problem when piping into vlc :

when I use :
# dvgrab - | mplayer -

it works very well with 0.5 sec latency

but when I do :

#dvgrab - | vlc -
it doesn't work and I get the following error message :

$ dvgrab - |vlc -
VLC media player 0.8.1 Janus
libhal.c 696 : org.freedesktop.DBus.Error.ServiceDoesNotExist raised
"Service "org.freedesktop.Hal" does not exist"


what's wrong ?
I would like to use vlc to trancode dv input to stream over network

thanks

That's not an essential error. It's a warning of a 3rd party library that won't shut up. It's not importatn

Try adding -vvv and see what VLC itself says.

[Guest]

Ok, I 've just seen while adding -vvv that the message says :

VLC was configured with ..... --disable-dv

I guess that's the problem


where can I get a VLC for mandrake complided with --enable-dv ?
thanks for helping

--disable-dv means it's not configured with dvlib. but ffmpeg has a dv decoder as well, so it should still work.
