Video geometric transform

saurabh206 — Fri, 12 Sep 2014 06:19:51 GMT

Hi,

Anyone has tried to do geometric transform on Video playback?

I want to do stretch, rotate and tilt the video playback.

Any suggestions from expert group.

Regards

Saurabh

Hi Saurabh

please check gstreamer scaling examples

GStreamer i.MX6 Pipelines

VPU rotation (it does not support resize)

mxc_vpu_test.out test:

-r <rotation angle> 0, 90, 180, 270

default rotation is disabled (0)

example of usage can be found below:

MPEG4 decode error on imx-6q

IPU resizing examples

ipu-examples release notes - v0.1

Best regards

Hi Saurabh

VPU can rotate only 0, 90, 180, or 270.

please check attached document:

Hi,

igor

I know VPU can rotate 0,90,180 or 270.

For my requirement I need to rotate the data after decoding.
