Hi, The code is already available in the driver for the RAW capture but it is not tested. You may also require some changes in order to make it work. You can add a new sensor driver and register it to the vpif capture driver. It supports some boot time parameters. You just need to set this to indicate that you are going to use raw capture mode. After this, I guess, all the required ioctl's are forwarded to the sensor driver instead of decoder driver. Let me know if you need anything further.

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
