Thanks!
It's actually the libvdpau-sunxi, I got confused by the naming (the
libvdpau-sunxi github page links to https://linux-sunxi.org/Cedrus which
refers to CedarX)
Hi,
the video engine is able to rotate the video while decoding, but its not
possible to export this feature with vdpau.
vdpau doesn't provide the information that it needs a rotated video at
decoding time, but only later at render time. You would have to look
into the future to do rotate at decoding time.
G2D is the only other part that can do rotation afterwards, but g2d
can't read the tiled video engine output, so it can't be used too.
Damn. Thank you Jens. I mixed up sunxi special OSD and Video
implementation once again ...

Andreas

Can you give advice on how to approach this? Is it at all possible to do
rotation with the CedarX driver?
I'd recommend you try it with the libvdpau-sunxi since it's at least
a code base that is amenable to improvements.
