graphics/display test -- gst_pipeline_test failed because of no element "ffmpegcolorspace"

Hi Betty,

There's one important detail I'd like to know about this bug.

Which version of Ubuntu are you running? I suspect you're using 13.04 :)

This bug is caused by the disappearance of the ffmpegcolorspace gstreamer element in gstreamer 1.0, it was replaced by videoconvert. So on 13.04 systems it will not work out-of-the-box.

I'll work on a fix for this, but I'd like to see confirmation on the Ubuntu version you have.

Thanks!

This is closely related to this bug:

Since this bug presented the problem in a Python script, it was easier to add logic to verify whether videoconvert element was present. The graphics/display test will be a bit more involved to fix, because it's a one-line bash command. Don't worry, this is a problem for me to solve :)

Hi Daniel

I believe CE QA team is running on 12.04.2.

Hi Jeffrey,

Of course, that makes sense because since checkbox installs gstreamer 1.0, when loading Python Gst it will load the most recent version, and ffmpegcolorspace does not exist in 1.0.

Thanks, this will be important when preparing the fix.

Compter has completely seized and mouse not available following update installation/applying changes. On reboot screen message "running in low graphics mode and whether I want to continue and other a few other options. However, cannot respond as trackpad does not respond any longer. Running Ubuntu12.04.

Please help as computer has failed completely.

Thanks, Ashok
