View Full Version : DFK 33UX246 gstreamer errors

September 8, 2017, 10:58:54

Running Linux Mint Debian Edition 2 and I keep getting errors when specifying height/width arguements.

user1@viewer1 ~ $ gst-launch-1.0 tcamsrc serial=XXXXXXXX ! video/x-raw,width=1920,height=1080,framerate=30/1 ! videoconvert
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

New clock: GstSystemClock
ERROR: from element /GstPipeline:pipeline0/GstTcamSrc:tcamsrc0: Internal data flow error.
Additional debug info:

I've tried quite a few different commands, specifying format etc. They always fail when I specify a resolution. All resolutions work in V4L2 test branch and Guvcview.

I tried the pipeline
gst-launch-1.0 tcamsrc serial=<serial>! video/x-raw,width=1920,height=1080,framerate=30/1 ! videoconvert ! ximagesink

with my DFK 33UX264 and it works fine on my computer.

I wonder, whether you use the lastest version from the github.

Also you may try
gst-launch-1.0 tcambin serial=<serial>! video/x-raw,width=1920,height=1080,framerate=30/1 ! videoconvert ! ximagesink

and see, what happens.
