Description w.vanhauwaert 2015-05-26 07:15:28 UTC

I'm using gstreamer on a Intel E3800 baytrail platform.
The vaapisink has a rotate-property, but no mirror/videoflip. gst-vaapi makes use of this libva. Now I wonder if the absence of such properties is some hardware-bottleneck or just not implemented yet? I can use the normal videoflip-method, but as this is done in software, my cpu can't handle it properly (for 4 streams). I need it because I want to display a stream from a camera, which needs to be mirrored.

The original bug report was https://bugs.freedesktop.org/show_bug.cgi?id=90654 (gstreamer-vaapi)

Are the above two scratch patches satisfy your requirement ? If yes, we will add the support for flipping in libva.

Comment 5 haihao 2015-11-24 04:37:21 UTC

Do you still require this feature? If not, I would like to close it.

Comment 6 w.vanhauwaert 2015-11-24 10:25:10 UTC

Yes, I still need it.
Though, I'm having another bug reported for my platform, which has also influences on this implementation. So I do it all in software for the moment (rotation/mirroring). But as I looked at your scratch patch, I think it will behave as requested, although not tested yet.
The bug I mentioned is 754820

We won't add support for this enhancement.
