We do not understand the segv message when quit by Cin and could not reproduce. Did you ever get a dump /tmp/cinelerraxxxxx.dmp file generated? If not, gg has no more ideas how to debug this. If you ever do get dump, send it our way.

I can understand you. Unfortunately only segv message come out and not dump file has been created, until now.

Yes, there are a few libva related libraries that have to be installed and libva-x11 is one of them. They are listed here: https://packages.ubuntu.com/source/xenial/libva

Thank you so much. It is very helpful to me.
Before you wrote this mail I copied from the Notebook, where cin20190430 works fine, the DEB file I find in "/var/cache/apt/archives/ and installed manually with "sudo dpkg -i DEB_PACKAGE_NAME".
The problem is the right sequences of the dependencies installations. I started from "libvdpau-dev" and "gstreamer1.0-vaapi-1.8.3". Then with Synaptic I see if there are broken files. Consider that my knowledge in Linux is zero, unfortuately. AND I don't know if my procedure is right.
I see here in mailing-lists that many user, if not all, "chew" Linux very well.

Do you mean that libva-x11 is missing? If so, see the entire related list at the last URL to see all of the packages that are needed.

In my Desktop system there is "libva-x11", or better I see it in folder "/usr/lib/x86_64linux-gnu/ ". May be it is not update, or not compatible with vaapi.

You can do a "GIT" for any previous version. How to do this is outlined in section 2.1.3 (create an initial clone) and 2.1.4 (build from a previous GIT version). If you have questions about that, just ask.

I mean to build the last release without vaapi or vdpau. And yes, I have read that section, thank you.
I know I am wasting your time with these things, and them are due at my poor knowledge to Linux system.
Thank you.
