I don't know if ffmpeg supports Bayer formats. The corresponding fourcc in
V4L2 is BA12.
ffmpeg doesn't seem to support these formats
If your sensor is hooked up to the OMAP3 ISP, you can then configure the
pipeline to include the preview engine and the resizer, and capture YUV data
at the resizer output.
I am using the OMAP3 ISP, but it's a bit unclear to me how to set up the pipeline
using media-ctl (I looked for documentation on this tool, but came up dry - is there any?)
Do you have an example of how to configure this using the OMAP3 ISP?
* Can I zoom/crop with this driver using the MCF? If so, how?
That depends on what host/bridge you use. The OMAP3 ISP has scaling
capabilities (controller by the crop rectangle at the resizer input and the
format at the resizer output), others might not.
Thanks
