[Kdenlive-devel] i cant capture with my webcam

[Javier Agustìn Fernàndez Arroyo]

hello,
i dont know if this is the corerct way for reporting problems... but let me
explain..

i have recently bought a webcam, and it works in videolan, using the
video4linux 2 setting. The device file is /dev/video0.

But in kdenlive, it shows "broken capture. Please check params"

this is the kdenlive log when i try to capture:

*kdenlive(9822) RecMonitor::slotRecord: Capture: Running ffmpeg  "-f
video4linux2 -s 320x240 -r 15 -i /dev/video0 -qscale 1 -ab 224k -vcodec
mpeg4 -acodec mp2 -y /home/elhoir/capture0000.mp4 -f mpegts -vcodec mpeg4
-acodec mp2 -"
kdenlive(9822) RecMonitor::slotRecord: Capture: Running ffplay  "-f mpegts
-x 465 -y 124 -"*

When running it in the command line, i get this:

*elhoir at elhoir-desktop:~$ ffmpeg  -f video4linux2 -s 320x240 -r 15 -i
/dev/video0 -qscale 1 -ab 224k -vcodec mpeg4 -acodec mp2 -y
/home/elhoir/capture0000.mp4 -f mpegts -vcodec mpeg4 -acodec mp2 -

/dev/video0: I/O error occurred
Usually that means that input file is truncated and/or corrupted.

Can anyone help me? Many thanks

The params string in kdenlive is this:

* -f video4linux2 -s 320x240 -r 15 -i /dev/video0*

Im using Ubuntu 9.04, and kdenlive 0.7.3 (too old?)
