HI All,
My objective is to interface CMOS sensor to DM6467, that CMOS sensor will be
giving data in RAW format(bayer).
As per SPRUER9B-december2008(TMS320DM646x DMSoC Video Port Interface User's
Guide) VPIF is capable of capturing RAW data. my understanding of RAW data
is getting seperate H-sync, V-sync and feild ID from sensor and giving it to
DM6467.my sensor is able to genrate these signals.
Even SPRUFJ3 – May 2008(LSP 1.30 DM6467 VPIF Capture Video Driver User
Guide) says that VPIF driver supports RAW capture mode.
But SPRS495 – Oct 2008(DaVinciTM Linux Drivers Datasheet) says that :
2.1.2.3.2 Features Not supported
Following are the features not supported by VPIF Capture Driver:
• Raw Capture mode
I am working on mvl4.0.1 and trying to analyse the VPIF driver files
davincihd_capture.c and vpif.c and it looks like that using ioctl calls for
e.g. "VIDIOC_S_FMT" to set the "storage format" and "pixel format" for RAW
format can help me in my task.
Does any body have any pointer to this problem.
Thanks in advance...
Regards,
Vivek
