Karicheri, Muralidharan a écrit :
We would like to explore if we can get volunteers from the community to
participate in this effort in porting remaining video drivers to upstream.
We are currently working to add vpbe display driver on DM6446/DM355/DM365. I
have listed below a set of work items that are available for grab. The work
involves modifying existing drivers(in some cases re-writing part of the
driver) at Arago tree and submitting the same to upstream. Please reply to this
list if you are willing to volunteer so that we can coordinate the same with
you.
1) Support HD capture on DM6467 using tvp7002(using HD timing API). tvp7002
driver is currently available in upstream and requires integration.
2) Support HD capture on DM365 using tvp7002(using HD timing API). tvp7002
driver is currently available in upstream and requires integration.
3) Support camera capture using mt9t031 sensor. mt9t031 is currently available
upstream and requires integration.
4) Develop and integrate mt9p031 sensor driver and integrate it with
vpfe_capture.
Regarding point 4, how is the cmos capture part supposed to work with the HD
video standards ?
Currently, to set the cmos capture resolution we have to :
set a video HD standards.
use TRY_FMT, S_FMT to set a windows that fits into the standard.
Currently, the highest resolution avilables are in the V4L2_STD_1080*
standard.
mt9t* chips have resolution up to 2048x1536
2Mpixels sensor comes with resolution like 1600x1200
not to mention the mt9p031 sensor.
What is the right way to handle this ?
add a V4L2_STD_IMAGER_STD with a 4096x4096 or higher resolution ?
5) one shot mode Preview and Resize drivers on DM355/DM365 using memory to
memory API (RFC recently submitted by Samsung)
6) vpfe capture enhancements using Previewer and Resizer in continuous mode.
7) vpif display enhancements for HD video.
8) Adding AEW/AF/Histogram support in vpfe capture driver.
Thanks.
