HI,

   SDK:  PROCESSOR_SDK_VISION_03_05_00_00

    A15 run  linux.

   Camera 30fps,  a frame 33ms.

   The encoding is more than 33ms.

   How to reduce the encoding time without reducing the definition of video recording

log:

    Hi,

    Please refer to the following datasheet for more information

    The IVA-HD codec can support 1080p@60 FPS real time decoding & 1080p@30 FPS real time encoding.

    Encoding can support > 30 FPS but it depends on the parameter configuration. Do some calculation to find out the FPS for other resolution

    There is a bug in the vision SDK encoder link, the IDRFrameInterval is not updated in the encoder link. Add the below changes & try again

    diff --git a/links_fw/src/rtos/links_ipu/iva/iva_enc/encLink_common.c b/links_fw/src/rtos/links_ipu/iva/iva_enc/encLink_common.c
