Hi,
lets be exact to the point

I believe my laptop have GUI capabilities but i can't use it in kdenlive as it make the kdenlive crashed each time i try it.

The current parameter for

Code: Select all

VAAPI INTEL H264

is

Code: Select all

f=mp4 vaapi_device=/dev/dri/renderD128 vf=’format=nv12,hwupload’ vcodec=h264_vaapi vb=30000k acodec=aac ab=192k

this is default.

And it fails everytime for this reason.

Rendering of /home/dev/Videos/final/Video3-Final cut.mp4 crashed

Code: Select all

One more thing i wanna say that in the error message

Code: Select all

libva: /tmp/.mount_kdenliy2zPJu/usr/lib/va/i965_drv_video.so has no function __vaDriverInit_1_0

libva is asking for a function _vaDriverInit_1_0
but in my vainfo my system has

Code: Select all

libva info: Found init function __vaDriverInit_1_10

Is this a bug if yes then how will i make use of vaapi in kdenlive gpu rendering.
