Hi,
>> Are these patches same as in your git branch tmp/imx-ipu-scaler ?
No, that is an older version.
Where can I get the recent ones ?
Could you push it to your public repo ?
when using it w/ gst for video playback, can be directly pass buffers
between VPU, IPU and FB (or let them directly write into shared
buffers), so CPU doesn't need to act on each frame for each step
in the decoding pipeline ?
Check out the (capture/output-)io-mode parameters, that's what the
dmabuf/dmabuf-import option pairs are for.
Tried dmabuf, but load stays at the same (77..80% CPU, 1.2 loadavg).
dmabuf-import doesnt run at all:
root@KoMo:/usr/share/videos/komo gst-launch-1.0 filesrc
location=montage.mp4 \! qtdemux \! h264parse \! v4l2video4dec
output-io-mode=5 \! v4l2video0convert capture-io-mode=5 output-io-mode=4
\! fbdevsink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element

Additional debug info:

ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...
Perhaps not implemented yet in the old version of the patches ?
By the way: do you have any idea whether the proprietary driver
(or the gpus itself) might talk to ipu and vpu ?
