Hi all,

We are using vision sdk IPU2 for camera & also as Display-server.(VisonSDK 3 dot 1 version).

We have two questions.

1. Consider IPU1 is used for Multimedia. & IPU2 for Display Server (GFX) + camera (VID1) .

In this case , it is possible to send the decoded data directly to IPU2 from IPU1 without USING WAYLAND-buffer OF a15 in a separate Pipeline line ?

2. Consider IPU2 is used with Multimedia,along with Display Server & camera.

Is it possible to send show the decoded data in IPU2 directly without resending to A15(waylandsink) ?

Currenlty we are using following gstreamer command from A15. Instead of wayalndsink, is it possible to have a gstreamer-plugin to handle in IPU2 ?

gst-launch-1.0 filesrc location=/tmp/SDCard_Slot-1/test.MP4 ! qtdemux ! h264parse ! ducatih264dec ! waylandsink

Hi Gokul,
Is your option1 of loading IPUMmm firmware on IPU1 working? If this is not available, it takes effort to use IPU1 for multimedia
as there are changes required in multiple places for Memory mapping

With IPu2 as default core for ipumm firmware, libdce, dce server and rpmsg drivers are implemented in such a way that,
VIDDEC3_process will return always to A15. With current implementation, it is not possible to avoid ducati frames coming back to A15.

Thanks
