DM6168 Encode path resolution supported

hi,

I am working on DM8168 with RDK and we are exploring the option of capture and encode resolutions beyond 1920x1080p30.

I have a few question about the maximum resolution that can be supported at 30Hz:

  1. In capture - does the VIP limitation is 165M and not resolution (like buffers size) - can we capture 2432x1024 @ 30Hz?
  2. In Hdvpss - does it support resolutions beyond 1920x1080?, if not - what is the limitation?
  3. In encode (H264) - according to documents up to 4k is supported, so no problem here, right?

thanks a lot,

Amir Gatt

    1. this resoluation looks fine.
    2. yes. Beyond 1920x1080 is possible. I am not sure of every module's limitation, but as i remember most module's limitation is less than 3840.
    3. yes but you can not do 4k@30fps.

    hi Eason,

     

    thanks for your quick reply, I have some follow up questions:

    regarding 2, we tried implementing over RDK 4.1 input at 640x480 and in the DEI scale to 2432x1080 resolution and encode, however we got only part of the picture at the left side and the rest of the picture was gery, when we lower the encode resolution to 2036x1080 it worked fine, but when every width beyond that 2048x1080 and so on we got different picture errors our encode path is:

    capture->select->DEI->merge->select->ipcOutVpss->ipcInVideo->ENC->ipcBitsOutRTOS->ipcBitsInHLOS.

    we are setting the initial capture resolution to 2432x1080 (since the parameter is transferred as the capture width to the encode link).

    Can you please think of potential errors in our implementation regarding the high resolution?

    Do you have an example for implementing resolution higher than FULL HD?

     

    regarding 3, you mean due to Level 5.1 frame size limitation, right?

     

    thanks a lot,

    Amir
