[Deepstream] How can I dynamically change the "config-path" of "nvdewarper" element?

[yuki.akimoto.sub]

The following pipeline is a sample using nvdewarper and works fine.

• pipeline command

  gst-launch-1.0 -ev \
  videotestsrc ! \
  "video/x-raw, width=(int)1920, height=(int)1080,     framerate=(fraction)60/1" ! \
  nvvideoconvert ! \
  "video/x-raw(memory:NVMM)" ! \
  nvdewarper config-file=dewarp_config.txt ! \
  nv3dsink
  

• dewarp_config.txt

  [property]
  num-batch-buffers=1
  
  [surface0]
  output-width=1920
  output-height=1080
  num-batch-buffers=1
  projection-type=1
  surface-index=0
  #dewarped surface parameters
  width=1920
  height=1080
  top-angle=45
  bottom-angle=-45
  pitch=0
  yaw=0
  roll=0
  src-x0=959.5
  src-y0=539.5
  focal-length=850
  

Target

I am trying to receive roll, pitch, and yaw via udp communication and dynamically update these information on surface0 while executing image processing using nvdewarp.

Question

Is it possible to dynamically update nvdewarper’s Configuration File Parameters such as roll, pitch, yaw, etc.? I tried to edit dewarp_config.txt while pipeline playing, but it didn’t update.

Please note that I am a beginner with 1 month experience with Gstreamer and 1 week experience with Deepstream.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

We do not currently support dynamic configuration of these parameters.
