DM385 for 4K*3K encode

Other Parts Discussed in Thread: DM385

I work on DM385 RDK3.5, and configure 4000*3072 resolution.

There are error when system run.

 [m3video] 9538:ERR::linkID:10000025::channelID:0::errorCode:-4::FileName:links_m3video/iva_enc/encLink_h264.c::linuNum:1321::errorCondition:(iresStatus == IRES_OK)

I'd like to know whether the encoder can support such a large resolution?

    Hi ,

    Check the encoder's datasheet under ti_tools/codecs/your-codec-lib-folder, check the maximum resolution supported.

    And , how is the usecase?    I am afraid that the issue is a combination , not the IVAHD alone.

    BR,

    Thanks!

    Constraints on resolutions are 4352x4096 in H264_Encoder_HDVICP2_UserGuide.pdf

    My usecase is low power.What do you suggest?

    How much memory requirements?

    The error indicates resource allocation failure and not encoder creation error.So the resolution is not the issue. This looks like memory allocation is failing .I am not familiar with IPNC RDK so not sure how to modify the memory map.

    You can confirm if it is memory allocation failure by adding debug prints in src_bios6/links_m3video/codec_utils/src/iresman_tiledmemory.c

    retryMemAlloc and check if Utils_memAlloc is failing.
