    IMP ==> Image Processor chained means, Image processor is connected CCDC, CCDC's output will be output to Image processor.

    Nagabhushana Nagabhushana
    Looks like sensor(which has decoder as well) you are can output NTSC/PAL. In vpfe_capture.c, you see calls specific to tvp514x which is a SD decoder(supports NTSC/PAL). You should be able to refer to that code and make appropriate changes in places where sensor is called.

    Can you verify nfs by using some other system to check whether it is configured properly. Also, I hope you have configured the virtual machine's network interface as 'bridged adapter'. I had seen problems with 'NAT' configuration for network.

    Nagabhushana Nagabhushana
    Driver is designed in such a way that PRV and RSZ can only work in either single-shot or continuous modes. If you want to change the mode, you need to reboot the board with boot parameter dm365_ipipe.oper_mode set correctly. dm365_ipipe.oper_mode=0 means PRV and RSZ can be configured in continuous...

    Have you configured IPIPE to convert bayer to UYVY? In previewer _set_ config check whether input color pattern is properly set.

    What Bayer format frames you captured using CCDC/ISIF? I believe CCDC supports Bayer-16, Bayer-8 DPCM compressed and Bayer-8 ALAW compressed.

    There are so many questions about 'how to capture interlaced video frames from VPFE". This thread is created to just address that. If you wan to capture D1 interlaced video from VPFE, there is no need to connect previewer and reszier in chained mode with CCDC. Simple way will be to capture...

    There is a single shot application available on arago(might be there in SDK also). You might wan to check the same to check your implementation of previewer single shot. http://arago-project.org/git/projects/?p=examples-davinci.git;a=blob;f=imp-prev-rsz/dm365/do_preview_resize.c;h=d150d7a217baa8fb920f49ecda75e09669558987;hb...

    Can you check what bootargs you have configured? Can you try using rootwait instead of rootdelay? From one of the patches:- "Starting from kernel 2.6.24 'rootwait' can be used to wait for the rootdevice to become ready, this is preferred over choosing a random delay. In the...

    I am not sure about the effort, but, If you can refer to VPBE user guide and the ycc8 link(as a reference), you should be able make appropriate changes. There is a similar thread on forum which might also help you - http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/99/t/88124.aspx
