Other Parts Discussed in Thread: TVP5147

I am working on capture from TVP5147 on TI8148 EVM.

I have tried with hdvpss package by adding device setting for TVP5147 and modifying captureVip example but in output only getting green frames.

Then I have tried with ezsdk also, but not getting proper steps to add TVP5147 driver to V4L2 drivers.

If anyone's capture from TVP5147 is working properly from any of the above ways, then please guide me with the some solution?

Hello,

There are community members which are successfully using tvp5147 & EZSDK.

You should add the TVP5147 as external decoder.
You could follow this user guide :

You could check this guide regarding v4l2 capture driver also:
