Linux: What is maximum content bitrate IvaDecoder supports to decode a 1920x1080p30 H264/MPEG2 video

Tool/software: Linux

Is there a content bit rate constraint with IvaDecoder.

What is the maximum bit rate IvaDecoder supports to decode a 1920x1080p30 H264 or MPEG2 stream?

Similarly any bit rate constraints with H264 Iva Encoder?

Are the bit rates different when both Iva Decoder and encoder runs simultanioulsy?

    Hi Srinivas,
    Please refer the Frequently Asked Questions section in Codec User Guide. It will serve your need.

    Hi Prashanth,
    That helped. Thanks a lot.

    It is mentioned that for CABAC streams (H264) max bit rate supported for real time decode of 1080 is 25Mbps for 266MHz of HDVICP2. Can i assume it will be max. 50Mbps if HDVICP2 frequency is set to 532MHz?

    In datasheet (H264), are the cycles numbers mentioned for non-error streams? What could be an additional overhead if the streams are full of errors? Any system overhead needs to be added to these numbers?

    -Srinivas.

    Yes, your understanding is correct.

    Yes, in DataSheet the numbers are of non-erroneous streams. Ideally we dont measure performance for erroneous streams. The reason for this is, it can be differ w.r.t the error present and the time to conceal it.
