Description Simon Farnsworth 2012-09-06 17:04:05 UTC 
Bob deinterlacing, as currently performed by the Intel Gen VA-API driver is unacceptably poor - the visual judder is noticeable on our typical setup.

Commit 6535bb8f804696a7e2cdd1dd3029a6eb680dd601 seems to explicitly disable advanced deinterlacing, even when trying to display both fields.

I'm using gstreamer-vaapi from the 0.3 branch as my interface into VA-API, and I'm happy to experiment with any suggestions.
Comment 1 Gwenole Beauchesne 2012-09-07 13:44:16 UTC 
Deinterlacing flags passed to vaPutSurface() are meant to render only either field in order to preserve GPU cycles and memory. Advanced deinterlacing are exposed through the VA/VPP interfaces. gstreamer-vaapi does not support the latter yet, though work is in progress.

We are escalating this issue.

Thanks,
