DM8168 catpure raw data from HDVPSS to ARM and store in H.D.D.

I use DVR_RDK 00.07.00.01, and try to find out a reference code about capturing raw data from HDVPSS to ARM and store in Hardisk. But I didn't found that.

Do you have any suggestion about this to start?

    Hi,

    In DVR RDK 00.07.00.01, there is no usecase to get the YUV captured data available on A8. We use propreitary tunneling implementation of OMX architecture, where in the YUV data does not go to A8 and instead goes to the encoder on M3. You can though change the tunnel and create a separate A8 based component and place it after capture and before encoder.

    The other option is use the Standard Non Tunneling approach where capture provides the data to A8.

    BTW, what is the usecase you are trying where you need YUV data on A8 and what is the channel density you are looking for?

    PS: Please mark this post as verified, if you think it has answered your question. Thanks.

    Hi Ansuman,
        I'm still not very familiar with implementation about your first or second method. And we may change A/D, D/A.
        To verify A/D, we may need raw data for each channel in A8. Is it possible to provide the example?
        Or you have any idea? Thanks

    Hi,

    Which A/D are you planning to use? Is it for multi-channel capture or single channel capture? I can suggest you different options based on that, just to verify that the raw data captured from A/D is correct.

    Currently, we do not have a component example that gets the YUV data to A8. But as i said, if you look at say the CMUX component on A8, you can replicate and place it after the capture component in the tunnel.

    ==> Would you mind to give an idea? Great thanks
