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 ? ) GST_DEBUG=3 gst-launch-1.0 flvmux name=mux streamable=true ! rtmpsink sync=true location="rtmp://xxxxxxx" rtspsrc location="rtsp://admin:admin@192.168.0.162:554/cam/realmonitor?channel=1&subtype=0" ! rtph264depay ! queue ! h264parse ! vaapidecode ! queue ! vaapiencode_h264 rate-control=cbr tune=high-compression ! mux. libva info: VA-API version 0.38.0 libva info: va_getDriverName() returns 0 libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so libva info: Found init function __vaDriverInit_0_38 libva info: va_openDriver() returns 0 Setting pipeline to PAUSED ...

This works fine with older vaapi <0.6 (default version in ubuntu 15.04). Please fix this bug for latest vaapi-0.6 or vaapi-master branch
As Sree answered you in the mailing list [1], here is not the correct place to file this bug. In my opinion this report should be closed and you should open a new one in the gstreamer-vaapi's bugtracker [2], providing more information about your problem. Mainly, as Sree already said, provide a log with GST_DEBUG=vaapi*:4, or maybe this other one GST_DEBUG="vaapi*:4,*:3" (the former gives information about the rest of the elements in the pipeline) Finally, spamming the personal emails of the hackers for bug reports, is not considered polite :) 1. http://lists.freedesktop.org/archives/libva/2015-September/003549.html 2. https://bugzilla.gnome.org/enter_bug.cgi?product=gstreamer-vaapi
