[gst-devel] dvdec + jpegenc & interations

[mammique <mam...@la...>]

Hi,

When i try to grab and compress an image from a DV camera to jpeg it
segfaults :

$ gst-launch-0.8 -i=2 dv1394src ! dvdec ! ffmpegcolorspace ! jpegenc !
filesink location=test.jpg
RUNNING pipeline ...
Erreur de segmentation (segfault)

But png works :

$ gst-launch-0.8 -i=2 dv1394src ! dvdec ! ffmpegcolorspace ! pngenc !
filesink location=test.png
RUNNING pipeline ...
Execution ended after 2 iterations (sum 1920218000 ns, average 960109000
ns, min 82874000 ns, max 1837344000 ns).

$ identify test.png
test.png PNG 720x480+0+0 DirectClass 8-bit 688kb 0.040u 0:01

BTW, i don't understand why this don't works with only one iteration, i
must specify 2 iterations to grab the image, if no the file is empty.

But it works with single iteration using simple raw dv grab :

$ gst-launch-0.8 -i=1 dv1394src ! filesink location=test.dv
RUNNING pipeline ...
Execution ended after 1 iterations (sum 106676000 ns, average 106676000
ns, min 106676000 ns, max 106676000 ns).

$ file test.dv
test.dv: DIF (DV) movie file (PAL)

Is it normal ?

Thank you.

Regards.

Camille.
