Comment (by akae):

 Hi,
 I'm also getting an error initializing the encoder with last git version.
 I've tried the modification to #define QSV_VERSION_MINOR to 6 in last,
 2.7.1 and 2.7.2 versions and recompiled all of them with no good results.

 The error in last version is


 {{{

 [h264_qsv @ 0x249c1e0] mfx init: /dev/dri/renderD129 fd open failed

 }}}

 I thought I should paste this here because the original error is an
 attached jpg and it's not properly indexed.

 The error I get in modified older versions is a segmentation fault.
