VPFE configuration

1) Is it possible to configure the VPFE at the application level and not driver level?  If at an application level, is there API documentation that lists and describes the available methods?

2) Configuring Still Image Capture instead of streaming and vice versa: does it require any kind of reset? What is the sequence?

3) Section 5.10.1.1.2 Still Image Capture, of TI document TMS320DM36x Digital Media System-on-Chip (DMSoC) Video Processing Front End (VPFE) User’s Guide (sprufg8c.pdf), describes the supported use case of Raw Image Capture (Figure 5-9) where the IPIPE has been disabled and the incoming raw image data is stored directly to the buffer.  Specifically,  the case where the incoming raw image has a width larger than 2176.  

• Is there sample code (similar to capture_prev_rsz_onthe_fly_yuv.c) that demonstrates how to set this up?  Or do we simply make calls to various functions from the VPFE driver (vpfe_capture.c).  If the latter, is there any documentation about the various functions or sample application code?
• Once the raw image data is in the buffer, can it be stored into a file directly, or does it have to pass through the IPIPE to format it into a suitable image type i.e. jpeg, tiff etc.  The buffer can be accessed via the DMA bus (according to the system block diagram of the DM36X).  
• If the IPIPE has to be involved, is there sample code for Multi-Pass Resize (Section 5.10.3.1.1 in sprufg8c.pdf) available?

Thanks in advance for your feedback.
