component input support for TVP514x video decoder

Other Parts Discussed in Thread: TVP5146

Hi,

I am using TI EVM 3530 by mistral. The linux driver for TVP514x supplied with the EVM only supports composite and S-video inputs and lacks support for Component input.

Where can I get the patch to support component video input in TVP514x?

Thanks,

Dhaval

    It looks like even the latest PSP does not support component input, unfortunately I have not come across any other TVP514x drivers for the OMAP3 so I do not know of a patch, this may be something you would have to modify the drivers to implement. It is possible that someone somewhere has done this, so hopefully someone else in the community can help out with this.

    Dhaval,

    If you are able to access the TVP's I2C interface then it is very simple to change the selected input and mode for the TVP5146/7.

    This might be a temporary fix for you. You could simply change the input after the normal configuration is performed.

    Hi Steve,

    Thanks for the suggestion. Yes I can access TVP5146 over I2c and will give it a try.

    What I was expecting is that, as its open source code, someone might have created a patch for this. Secondly, if there is no patch for the code, how a developer like me can contribute my code so that others can also make use of it?

    Thanks & Regards,

    Dhaval,

    Unfortunately I am a hardware person so don't really know much about the software process.

    I will pass the link to someone who may be able to better answer this though.

    If you need additional help in configuring the video decoder please so not hesitate to ask and I will try to help.

    BR,

    Dhaval,

    Several platforms including DM644x and I believe DM646x use TVP514x analog video decoders.  You may want to check the TVP514x drivers provided with these for the component video input support you require. 

    Chances are one of these may already have it and save you the work, etc.
