Subject: How to configure resizer in ISP pipeline?
Date: Tue, 11 Dec 2012 15:48:23 +0100 [thread overview]
Message-ID: <50C747B7.20107@gmx.net> (raw)
Hello,
using Media Controller API, I can successfully configure a simple ISP
pipeline on an OMAP3530 and capture video data. Now I want to include
the resizer. So the pipeline would look like this (where MEM would be
the devnode corresponding to "resizer output"):
Sensor --> CCDC --> Resizer --> MEM
My "sensor" (TVP5146) already provides YUV data, so I can skip the
previewer. I tried setting the input and output pad of the resizer
subdevice to incoming resolution (input pad) and desired resolution
(output pad). For example: 720x576 --> 352x288. But it didn't work out
quite well.
Can someone explain how one properly configures the resizer in an ISP
pipeline (with Media Controller API) ? I spend some hours researching,
but this topic seems to be a well guarded secret...
Kind regards,
Andreas
