Hello,
I am getting 70-80% cpu load when playing any youtube video. But when i download mp4 file manually and watch it with gst-play-1.0 everything is alright and cpu load is around 3-5%. In both cases i can see that output in console:
libva info: VA-API version 0.38.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/local/lib/va/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_38
libva info: va_openDriver() returns 0

Versions of packages installed:
firefox-esr-38.2.1 gstreamer1-1.4.5_1 gstreamer1-libav-1.4.5 gstreamer1-plugins-1.4.5_2 gstreamer1-plugins-all-1.4_1 gstreamer1-plugins-bad-1.4.5_1 gstreamer1-plugins-faad-1.4.5 gstreamer1-plugins-good-1.4.5 gstreamer1-plugins-mpeg2dec-1.4.5 gstreamer1-plugins-mpeg2enc-1.4.5 gstreamer1-plugins-opus-1.4.5 gstreamer1-plugins-ugly-1.4.5 gstreamer1-plugins-vpx-1.4.5_1 gstreamer1-plugins-x264-1.4.5_1 gstreamer1-vaapi-0.5.10_1

May be i am doing something wrong? It's the same with the clear firefox profile.
