audio_common for ROS2
Hi everyone, is there any audio_common equivalent package for ROS2?
Thanks in advance, Cheers, G.
Hi BrettRD, thanks for starting and sharing such an ambitious project! My use-case is closer to the original audio_common: Play one from a set of audio files located on disk through ROS commands. Do you have a tutorial or instructions on how to do this with your project? I failed to find this on the linked github page. Cheers!
I don't have many examples of using ROS for audio. I have some improvements penciled in for this year though, that includes more docs.
Off the top of my head, A pipeline like this should do something, (something might include eating all of your network bandwidth with raw audio):
Machine with the mic:
gst-launch-1.0 --gst-plugin-path=install/gst_bridge/lib/gst_bridge/ alsasrc ! audioconvert ! rosaudiosink ros-name="mic_node" ros-topic="very_noise"
Machine with the speakers:
gst-launch-1.0 --gst-plugin-path=install/gst_bridge/lib/gst_bridge/ rosaudiosrc ros-name="spk_node" ros-topic="very_noise" ! audioconvert ! alsasink sync=false
If you have a burning need for compressed audio in ROS, I'd love to field a pull request (even one that doesn't yet work) for a ROS message wrapper and bridge nodes that handle raw GST buffers.
rosrawsink and rosrawsrc are on my wish-list.
At the moment, I use GStreamer's UDP elements to move H264 video, not ROS topics.
I have the same question and am not sure whether the project linked in the accepted answer actually addresses this. Hence, I opened a question on the github of github_common: https://github.com/ros-drivers/audio_...
