I have used gstreamer-vaapi-0.2.5 and ffmpeg version ffmpeg-0.8.4... I have tried using video data  dump of mpeg2files ..without parser.

In that case mpeg2video frame is getting displayed....None of the demuxers working with vaapidecode..cap negotiation failure in all cases.

Can some one provide me a solution for this.
