gstreamer-vaapi broken ? problem connecting vaapidecode to vaapiencode_h264 ?

Hi,

I installed latest intel graphics for linux by following wiki on ubuntu 15.04/intel baytrail (lenevo B50 touch laptop).:

https://01.org/linuxgraphics/downloads/intel-graphics-installer-linux-1.2.0

I am trying to execute following pipeline : (It seems that vaapidecode is unable to connect with vaapiencode_h264 .  Can anyone tell me why it is failing  ? )

Hi There,

Because you are using graphic driver from 01.org, it is OTC driver. Maybe following URL can help you :

https://01.org/linuxgraphics/forum

https://01.org/linuxgraphics/forum/graphics-installer-discussions

 

Thanks
