3.1 Gstreamer

For gstreamer, it will not work with prebuilt gstreamer drm allocator. It needs Gstreamer OmapDRM allocator support. We provide a patch to support this feature.

Use the following steps in order to run the decode feature:

  1. Enable IPUMM in VISON SDK.

    PROCESSOR_SDK_VISION_03_05_00_00/vision_sdk/apps/configs/tda2xx_evm_linux_all/cfg.mk

    # Both IVAHD_INCLUDE & IPUMM_INCLUDE should not be set to "yes"
# Only one should be enabled to avoid IVA-HD resource conflict
IPUMM_INCLUDE=yes
IVAHD_INCLUDE=no
  2. Boot the board, run the command shown below:
    root@dra7xx-evm# cd /opt/vision_sdk
root@dra7xx-evm# ./vision_sdk_load.sh
root@dra7xx-evm# ./apps.out
# press 1 to select : single camera usecases
# press 8 to select :  dispDistSrc -> display usecase
root@dra7xx-evm#  gst-launch-1.0 playbin uri=file:///home/root/test.mp4 video-sink=waylandsink
