Updates, autofocus, 5Mpix mode on N900? Re: [RFC 08/13] smiapp-pll: Take existing divisor into account in minimum divisor check Pavel Machek <pavel@ucw.cz> - 2017-03-23 00:50 +0100

We are quite close to working camera now... Plus I have played with v4l-utils, and managed to implement autofocus and autoexposure -- it was easier than expected. I believe you mentioned you had some patches to automatically initialize the pipeline. Do you and can I have them? Last thing.. Is someone able to compute new modes for et8ek8? I believe smaller than 640x480 mode would be useful for video streaming, and I still can't get 5MPix mode to work; understanding what goes on there would be useful.

Oh and.. is it possible to generate modes with more than 30fps? I guess that would be useful for initial autofocus/autogain....

The PLL calculator really requires that to be able to test any changes made to it. > > Plus I have played with v4l-utils, and managed to implement autofocus > and autoexposure -- it was easier than expected.

Given a video node, it can find possible pipelines to the image sources with common formats. I.e. the ccdc -> rsz path is not available for raw cameras. C (especially without helper libraries) wasn't particularly suitable for the task, the data structures I had didn't end up too nice. What would also be necessary is to associate library or application specific data to entities, this could be as simple as key-value pairs with both key and value being pointers. > > Last thing..

Unfortunately the et8ek8 does not conform to a standard such as SMIA. :-( I'm not sure the datasheet provides enough information to come up with new mode definitions. Perhaps with some experimentation it could be possible. There are a few additional embedded documents in it, those are worth checking out. LibreOffice can open them AFAIR. -- Regards, Sakari Ailus e-mail: sakari.ailus@iki.fi XMPP: sailus@retiisi.org.uk

Could I get a copy, anyway? Need not be perfect, but starting point would be welcome.
