Hi All,

   I'm looking for a way to encode(H.264) 1920*1080  YUV422 16bit  source based on DM368. Because of  the  DDR BW  bottle neck ,TI suggest the data flow:1080p30 -> ISIF -> IPIPE+RSZ -> DDR (1080p30 YUV420) -> H264 encode -> DDR (bitstream) -> network stream (RTSP). But the input is BT.1120 which is YUV422 16bit. so i need change the YUV422 to YUV420PS. how could i do? Thanks

    You can use the same way as TI suggested, the resizer has the capability  to convert a

    a yuv422 image to yuv420SP (I hope you needed the same becoz above its youv420PS).

    So you give input to resizer as YUV422 image and the output of resizer is YUV420SP.

    hi prabhakar: I have tried to use the resizer. But I found the color was wrong. I am not sure all the registers of resizer are right set. Later, i will plaster the picture.

    The problem has been solved. The data type of IPIPEIF was set RAW. It should be set YUV.
