Hi,

Can you read that video directly using GStreamer ?

[Jonathan Levanon]

@SGaist
Actually I can't -

sudo gst-launch -v playbin2 uri=file://U1_Test_Test030.avi

@Jonathan-Levanon Why sudo?

[Jonathan Levanon]

@jsulm Without sudo it's the same..

[SGaist]

Which version is this get-launch ?

[Jonathan Levanon]

@SGaist
gst-launch-0.10 version 0.10.36
GStreamer 0.10.36
https://launchpad.net/distros/ubuntu/+source/gstreamer0.10

[SGaist]

Might be a silly question but do you have proper access to that file ?

Did you check whether it's broken ?

Can you test again but with the 1.0 tools ?

[Jonathan Levanon]

@SGaist
I have access, triple-checked it.
With 1.0 I get
ERROR: pipeline could not be constructed: no element "playbin2".

Tried remove and reinstall all gstreamer-1.0 stuff, nothing changed

I've used export GST_DEBUG=4, log is on https://pastebin.com/742JBtba

[SGaist]

What if you try to use only playbin ?

[Jonathan Levanon]

@SGaist Same error ERROR: pipeline could not be constructed: no element "playbin".

[SGaist]

You should run gst-inspect to see what you have available on your system.
