problem while using dv1394src

[julien quelen]

Hello all,

I try to capture images from a Firewire camera, using dv1394src plugin.

My pipeline is:

gst-launch dv1394src port=0 ! video/x-dv ! dvdemux ! dvdec ! xvimagesink

The pipeline goes in playing mode without any error/warning. Then it
blocks and no image appears.

While looking in the code, I saw that dv1394src blocks in the poll()
function contained in plugin's create() function.
I don't have any dmesg warning.

I use:
libdc1394-2.0.1
libraw1394-1.3.0
libiec61883-1.1.0

Does somebody has any tip that would help me?

thanks

Julien Quelen

It sounds there is a problem with the synchronizing.
Could you add the following parameter to xvimagesink : sync=false

Hi Samuel,

I put:

gst-launch dv1394src port=0 ! video/x-dv ! dvdemux ! dvdec !
xvimagesink qos=false max-lateness=-1 sync=false

And it didn't change anything. thanks anyway

I verified that nothing goes out of dv1394src. As dv1394src get
blocked in his poll()
function I guess it's a camera configuration/start problem.. but which one?
(I use a Pixelink PL-B742 camera)
