Run a GStreamer* Audio Pipeline using GStreamer* Plugins in Docker* Container
Run the Sample Application
Go to the AMR_containers folder:
cd <edge_insights_for_amr_path>/Edge_Insights_for_Autonomous_Mobile_Robots_<version>/AMR_containers
Prepare environment setup:
source 01_docker_sdk_env/docker_compose/05_tutorials/config/docker_compose.source export CONTAINER_BASE_PATH=`pwd` export ROS_DOMAIN_ID=34
Run an automated yml file that opens a GStreamer* sample application inside the EI for AMR Docker* container.
CHOOSE_USER=eiforamr docker-compose -f 01_docker_sdk_env/docker_compose/05_tutorials/gstreamer_audio.demo.yml up
Expected output:
#gst-launch-1.0 filesrc location=/data_samples/media_samples/sample.ogg ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! Testsink error: XDG_RUNTIME_DIR not set in the environment. Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock Got EOS from element "pipeline0". Execution ended after 0:01:14.349609320 Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ...
To close this, do one of the following:
Type Ctrl-c in the terminal where you did the up command.
Run this command in another terminal:
CHOOSE_USER=eiforamr docker-compose -f 01_docker_sdk_env/docker_compose/05_tutorials/gstreamer_audio.demo.yml down
For an explanation of what happened, open the yml file:
The first 23 lines are from the EI for AMR infrastructure.
Line 26 plays the audio file using GStreamer*.
To use your own audio, use the same yml file but update line 26 to target your own file.
For example, copy the file:
cp test.ogg ${CONTAINER_BASE_PATH}/01_docker_sdk_env/docker_compose/05_tutorials/test.oggAnd update line 26 to:
gst-launch-1.0 filesrc location=${CONTAINER_BASE_PATH}/01_docker_sdk_env/docker_compose/05_tutorials/test.ogg ! oggdemux ! vorbisdec ! audioconvert ! audioresample ! testsink
