Hi Sakari,
thanks for helping.
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
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 --

This could as well be an issue with the kernel API --- I think that kernel

Hi Sakari,
thanks for helping.
My code sets up the ISP pipeline, configures the format on all the
subdevices pads and the actual video device. Works fine so far.
Then I passed user pointers (aquired with malloc) to the device
driver for the capture buffers. Before issuing VIDIOC_STREAMON, I
Hello,
in order to familiarize myself with Media Controller and V4L2 I am
creating a small example program for capturing some frames through the
OMAP3 ISP.
The hardware used is a TAO-3530 on a Tsunami daughterboard from
Technexion. My video source is a standard DVD player connected to the
signal.
I'm going to try the latest mainline kernel, but I doubt it will work.
Kind regards,
Andreas

Hello,
I am using an embedded module called TAO-3530 from Technexion, which has
an OMAP3530 processor.
This processor has a camera interface, which is part of the ISP
submodule. For an ongoing project I want to capture a video signal from
this interface. After several days of excessive
