Hi all,
As explained in my first mail I would like port the tvp515x driver to
new media framework, I'm a newbie with the v4l2 API and of course with
the new media framework API, so sorry if next questions are stupid or
trivial (please, patience with me).
My idea is follow this link schem:
---------------------------------------
--------------------------------------------
--------------------- | | | 1
| ----------> | OMAP3 ISP CCDC OUTPUT |
| TVP515x | 0 | -----> | 0 | OMAP3 ISP CCDC --- |
--------------------------------------------
-------------------- | | | 2 |
---------------------------------------
Where:
* TVP515x is /dev/v4l-subdev8 c 81 15
* OMAP3 ISP CCDC is /dev/v4l-subdev2 c 81 4
* OMAP3 ISP CCDC OUTPUT is /dev/video2 c 81 5
Then activate these links with
./media-ctl -r -l '"tvp5150 2-005c":0->"OMAP3 ISP CCDC":0[1], "OMAP3
ISP CCDC":1->"OMAP3 ISP CCDC output":0[1]'
Resetting all links to disabled
Setting up link 16:0 -> 5:0 [1]
Setting up link 5:1 -> 6:0 [1]
I'm on the right way or I'm completely lost ?
I think the next step is adapt the tvp515x driver to new media
framework, I'm not sure how to do this, someone can give some points ?
Once this is done, I suppose I can test using gstreamer, for example
using something like this.
gst-launch v4l2src device=/dev/video2 ! ffmpegcolorspace ! xvimagesink
I'm right in this point ?
Any help will be apreciated.
Thanks in advance,
Enric
