TDA2HG: [GStreamer video window position control ]

Part Number: TDA2HG

Hi All:

Introduction

  As discussed above, we're working on visionSDK 3.05 with QT 5.6.2 for our DVR development.

and, we are succeed to run the video playback by gstreamer.

Question

1. how to control the gstreamer window position as it will be overlay by our QT UI

           As my understood that the desktop shell did not support position control except the ivi-shell.

          QT 5.6.2 not support the ivi-shell except QT version bigger then 5..7.0

          above all, should we upgrade the visionSDK 3.05 to 3.08 which support QT5.11

      2.when upgrade to visionSDK 3.08, here is the description about video playback with gstreamer.

4.4 IPUMM based decode use-case using Gstreamer
4.4.1 IPUMM and VSDK-Linux on IPU-2
From Vision-SDK 3.5, support is provided for IPUMM based decode using GStreamer
plugin. Follow section 2.4.2.2 of this document to include IPUMM as part of the
primary IPU (IPU-2) build. Please note when IPUMM is included, IVAHD needs to
be set to no in the corresponding apps/configs/<evm_id>_linux_all/cfg.mk file.
Gstreamer playback requires vpe plugin to be available, so A15 accesses vpe.
Set VPE_INCLUDE=no in apps/configs/<evm_id>_linux_all/cfg.mk
Comment DISABLE_COMPLETE(vpe); statement in the device tree file to make vpe
available for A15

  why video  playback using the VPE different with visionSDK 3.05.

  we also expect to use gstreamer for video recording, that VPE is already used to convert the YUV422 to NV12 in IPU2.

Thanks...
