TVP5158 v4l2 driver

Other Parts Discussed in Thread: TVP5158, TVP5147

Can the TVP5158 driver for DM6467 be used as a regular v4l2 driver with single channel mode? How difficult would be to modify it to work like that?

Why do I need this? We have a board with DM6467 and two TVP5158 and it can run the 8 channel D1 streamer demo. I want to use the same board for another app using v4l2 capture and without having to change this app to work with the demultiplexing capture.

Regards,

Victor

    Hi Victor,

    The v4l2 driver does work for single channel mode since the DM6467 EVM has TVP5147 on board and it is single channel.

    The TVP5158 can output single channel if you setting it to bypass mode.  When TVP5158 in bypass mode, it output only CH1 and the output is in BT656 format just like TVP5147.

    So, it is possible to do what you need.  But you have to combine the TVP5158 and TVP5147 drivers together.

    Regards,
