USE A FPGA to repalce tvp7002,and then capture video with v4l2?

Other Parts Discussed in Thread: TVP7002

hi,everybody!

i have a 8168 evm board and made a capture board(cameralink interface ) with FPGA .i have tested in omx(comment out all of 7002) ,it can work perfectly.now,i want to use v4l2 to capture video.

in capture board ,have connected 24 pins  to VIN0[0]~VIN[23],and hs,vs,de.so could this fpga replace 7002 in v4l2 capture?

thank you

    Hi David,

    There are several threads in this forum, discussing how to use FPGA instead of TVP7002 for capture:

    Software overview

    V4L2 capture driver provides the application interface for the video capture processing modules of the VPSS. It allows the external decoders to be interfaced to VIP capture port of the VPSS through standard V4L2 sub device driver model. Current driver supports VIP 0 instance with TVP7002 decoder on I/O expansion cards of TI814x and TI816x. It is possible to support other decoders on VIP 0 instance by adding the sub-device driver for required decoder and passing the board specific data through board file. Please refer to the application note on how to add different decoders to the V4L2 capture driver.
