Rohit Shanbhag
Expert 1075 points

Hi ,

Am using customised board based on dm368 which has ovsensor 2715 which gives only RAW 10bit data as output . Capturing is happening successfully which i could trace in some Tuning player.What should i do , if i want to put those data to LCD ?

Is it supported in dm368? is der any way to do this ?

Regards

    Hi Rohit,

    There are numerous examples for loopback demos - you can check dvsdk-demos or gstreamer (depending on your dvsdk version).

    If you are currently verifying upto Bayer data, then you'll need to get the IPIPE working so that the YUV data is available.

    Hi Rohit,

    Have you referred to this http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines ?

    It covers almost all the use-cases.
