Capturing Video on DM8148 Mistral

Hi everyone!

We have the Mistral Centaurus BETA Brd and an additional daughter card (MS_CVCAM).

My questions is, does it work with the current OMX SDK (ezsdk ..00_26) to caputure video from the daughter card (it has a parallel camera connector).
If not does it work with V4L (PSP 4.00.00.05)?

The S-Video and Composite  IF on the base EVM are outputs only right?
Furthermore, as I couldn't find the information myself: What are the 3 CSI and 2 HSPI IF?

Thanks

Markus

    Hi,

    V4L2 capture is not supported as of now on any of the PSP Releases. Yes S-Video and composite IF on the EVM are outputs from SD Venc.

    Hi Markus,

     

    From HDVPSS team, We have not validated Camera daughter card.

     

    Yes, SVideo and Composite connectors on the base evm are for the SDVENC output.

     

    Thx,

    Hmm, ok thanks for the replies.

    Is it possible to capture from the Parallel Camera connector using OpenMax? The daughtercard specification we ahave available looks rather like a draft/proposal, so it is pretty hard to tell how it is connected to the processor (don't even know if there is some converter or adapter in between).

    Just to be sure, is it currently possible to use fetch an RTP stream using OpenMax? I think I read it isn't supported, but I might be mistaken.

     

     

    EDIT: Another question: If I enable USB V4L devices in the kernel, it will be possible capture those using V4L?
    In this case the A8 will do the memory operations. Is it possible touse EDAM here or to accelerate it such that I just "give" the memory adress of the input buffer to the HDVPSS/Video system (i.e. integrate it into the OpenMax chain)?

    Sry, I'm pretty new to this topic.

    Thx,

    Markus
