    Hi Margarita
    I use DVRRDK4.1, I run the VDEC_VDIS demo, write the output yuv of decoder, seems the decoder run error. I want to decode demo run from ccs to check if the decode lib have some bugs.

    The version of the H.264 decode lib is 02.00.08.00.

    Hi Eric,

    Can you more elaborate on "to check if the decode lib have some bugs" ??
    If you are suspecting any encoded stream & if you are getting any error while decoding. Based on the error log, you can find the reason for the error. If decoder is setting error, then please share the stream along error log.

    Hi Eric,

    The issue is not with Decoder. The requirement is output should be without padding which is again feed to Encoder.
    This can be handled by using the providing the proper start pointer along with pitch. Can you let me know which Codec version of Encoder you are using to Encode ??

    Hi

     REL.500.V.H264AVC.D.HP.IVAHD.02.00.08.00    REL.500.V.H264AVC.E.IVAHD.02.00.06.00

     My application link flow :   because the decoder output have padding pixels, it cause all following link process frame with padding pixels.

    Hi Eric,

    In that case only you have to handle the inputBufDesc of  imageRegion & activeFrameRegion.

    imageRegion  ==> Whole frame as image region ( e.g 2048x2048)

    ActiveFrameRegion ==> Only contents need to be used for encoding ( e.g 1920x1080).

    So the ActiveFrameRegion can be anywhere in ImageRegion. So in the RDK Framework, please check the below parameters for the region selection.

    For Image Region = Pad + Input Width = Also called Capture Width

    For Active Region = Only input Width 

    Similar modification for Height.

    1 - topLeft.x  

    2 - topLeft.y

    3 - bottomRight.x

    4 - bottomRight.y

    Regards
