Description james.wilford 2016-07-29 20:15:40 UTC

I installed kdenlive, melt and vidstab from the testing PPA. In /etc/apt/sources.list.d/kdenlive-ubuntu-kdenlive-testing-xenial.list I have:

deb http://ppa.launchpad.net/kdenlive/kdenlive-testing/ubuntu xenial main

dpkg shows:

ii  kdenlive                                        4:16.07.80+git201607272128~ubuntu16.04.1   amd64        non-linear video editor
ii  melt                                            6.3.0+git201607241850~ubuntu16.04.1        amd64        command line media player and video editor
ii  libvidstab0.9:amd64                             0.98b-1                                    amd64        Video stabilization library (runtime)

However, when I query melt to see which filters are available, vidstab is not there. I only see the older videostab and videostab2 filters which I understand are deprecated.

$ melt -query filters | grep stab
  - videostab
  - videostab2

In kdenlive, under the clip jobs > stabilise menu, I only have videostab2. I would like to use vid.stab as I understand it provides much better stabilisation.

I also tried with the stable ppa in a VM, and the result is the same - the vidstab filter is not shown when querying melt.



Reproducible: Always

Steps to Reproduce:
1. Add kdenlive-stable or kdenlive-testing PPA
2. Install kdenlive and libvidstab0.9
3. Run "melt -query | grep stab"

Actual Results:  
  - videostab
  - videostab2


Expected Results:  
- videostab
- videostab2
- vidstab

This bug affects me too.

Comment 2 David Edwards 2016-09-13 08:20:18 UTC

Same here. In kdenlive, only videostab2 displays in the Stabilize menu, and it doesn't work; "Invalid clip" when it tries to import the stabilized clip into the project after processing.

Happy to help diagnose, if anyone can give any pointers on where to look.

On a recent Kdenlive installed from project ppas on Kubuntu 16.04LTS, I properly see vidstab and can successfully run the vidstab job. I remember seeing some fix for the job detection, but this should not be at the root cause of this bug report.

I suspect this to be a distro packaging issue. Can you please try installing from development ppa first, then from stable ppa?

Comment 4 james.wilford 2016-10-09 14:01:32 UTC

Thanks - I can confirm that the following steps fixed it:
1. install from development (master) ppa
2. remove kdenlive
3. remove development ppa and add stable ppa
4. install kdenlive

Comment 5 Vincent PINON 2016-10-13 19:31:01 UTC

I had fixed MLT packaging in kdenlive-master PPA, but forgot to apply the change in stable.
Should be OK now.
Thanks for pointing this,

Vincent
