3.1 Gstreamer

对于 gstreamer，它不能与预构建的 gstreamer drm 分配器一起工作。它需要 Gstreamer OmapDRM 分配器支持。我们提供了一个补丁来支持此功能。

使用以下步骤运行解码功能：

在 VISON SDK 中启用 IPUMM。

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

启动主板，运行如下所示的命令：

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
