I have a NVidia 210 GeForce.
It's my first time here and if I made a mistake sorry, wasn't my pretention.
Comment 1 Ilia Mirkin 2016-07-16 00:38:49 UTC 
Do you know whether kdenlive does GL and VDPAU calls from parallel threads?

Separately, what version of libdrm(_nouveau) do you have?
Comment 2 Rafael Favero 2016-07-16 13:12:24 UTC 
Maybe I made a mistake, I was advised to report the problem here, but I was on another forum and one user tell me that the problema maybe wasn't especific on the driver, but could really be on Kdenlive. I really know few about this things and I think I could not help this, I'll try to contact Kdenlive's support to show the mistake, thanks for the help.
Comment 3 Rafael Favero 2016-07-18 13:43:51 UTC 
I upgraded Ubuntu to 16.04 and Kdenlive to lastest version, but the problem continue, I'm a normal user and I don't know how does GL and VDPAU calls from parallel threads, and the version of libdrm(_nouveau)is 2.4.67-1ubuntu0.16.04.1.
