h.264 encoder in c6678 working with video resolution 4K

Yongshan Cui

I encode the video with encoder version C66x_h264hpvenc_01_00_02_00_ELF_32bit, and I can use the sample test application.

When the resolution is 1920x1080,it can work well,but when it is 4096x3840,the application failed at creation.

It says I just have to change the parameters width, height and provide enough buffers.

I want to know the buffer needs when the resolution changed,how should I change the buffer size?

Thank  you!

    Hi,
    Sorry for reply so late, the encoder can work fine now, I use the config file encoder.cfg in the encoder folder:
    C:\ti\Codecs\C66x_h264hpvenc_01_00_02_00_ELF\packages\ti\sdo\codecs\h264hpvenc\App\Client\Test\TestVecs\Config
    the following is the changes in the config file:
    MaxWidth = 4096 # Max Frame width
    MaxHeight = 3840 # Max Frame height

    inputWidth = 4096 # width of image
    inputHeight = 3840 # Height of image

    The following is the changes in the program:
    XDAS_UInt8 InBuffers[(4096*3840 + 4096*3840 + 32 )*9];
    #define CORE_EXT_DATA_MEM_SIZE (80 * 1024 * 1024)
    #define EXTERNAL_SHARED_DATA_MEM_SIZE (200 * 1024 * 1024)
