YUV 422 decoder

Hello,

I would like to ask if there is some way to decode information which was encoded as YUV422 format with HDVICP2 codecs (mpeg4,mpeg2, h.264). if not - is it possible first to convert the encoded stream to yuv420 and then make the decoding ?

Thanks,

Ran

    Hi,

    HDVICP2 doesnt support YUV422 decoding. Further there is not way for converted encoded YUV422 data to YUV420 data.

    Hi Hardik,

    Is there any way using Netra that we can decode of 422, 10 bits . Is it possible using DSP ? Is it possible by writing custom codec maybe?

    Is it a hardware limitation ? where exactly is the limitation ?

    Thank you,

    Ran

    Hi, It may be possible to use open source codec and optimize it for DSP for YUV422 10 bit decoder. But you will never get performance with software codec which will be available with hardware codecs. You may at max get 576P or VGA with software codecs with YUV422 10-bit. Again this is a very rough estimate but you will never get 1080P performance with software codecs.

    Hardik,

    If I'm using the DSP, there is no hardware limitation for decoding 422, 10 bits ? such DSP codec should do the following, is that possible in Netra ?

         a. store in memory YUV422, 10 bits
         b. use DVO output as YUV422, 10 bits

    Regards,

    Ran

    TI is not having this codec, you have to develop yourself.

    10 bit display and capture both are not supported for Netra.
