Forum Post: about the decoder

Hi ,

   As the picture showed above which is from the doc <H264_Decoder_HDVICP2_UserGuide> Page 129 , I want to know more about it . Could I use the activeRegion to get the data which I need to decode? For example , the image size is 1920 * 1080, and I just want to get 480*270 to decode.

    I will appreciate your help !

Thanks!

Best regards!
