Autoware播放提示音
播放提示音
1、修改sound_player.yaml
src/autoware/utilities/sound_player/scripts/sound_player.yaml
'start' : ~/Autoware/install/sound_player/share/sound_player/start.wav
'stop' : ~/Autoware/install/sound_player/share/sound_player/stop.wav
'red signal' : ~/Autoware/install/sound_player/share/sound_player/red.wav
'green signal' : ~/Autoware/install/sound_player/share/sound_player/green.wav
'pedestrian' : ~/Autoware/install/sound_player/share/sound_player/pede.wav
'ndt warning' : ~/Autoware/install/sound_player/share/sound_player/ndt_warning.wav
'deceleration' : ~/Autoware/install/sound_player/share/sound_player/deceleration.wav
'return to normal run' : ~/Autoware/install/sound_player/share/sound_player/return_normal.wav2、运行sound_player
$ rosrun sound_player sound_player.py
loading sound_player.yaml
[INFO] [1625024290.737267]: sound_play node is ready to play sound
3、播放
rostopic pub -1 /sound_player std_msgs/String -- 'start'
$ rostopic pub -1 /sound_player std_msgs/String -- 'start'
publishing and latching message for 3.0 seconds
sound_player运行窗口可以看到如下提示，同时可以听到声音。
autoware@3890dae21c45:~/Autoware$ rosrun sound_player sound_player.py

Autoware中的sound_player包，引用ROS中的sound_play包进行播放声音。sound_play的源码位于/opt/ros/melodic/lib/python2.7/dist-packages/sound_play。直接用sound_play进行播放声音测试，提示如下错误。
$ rosrun sound_play soundplay_node.py

播放声音时，提示上述错误，需要安装gstreamer1.0-alsa。
$ sudo apt-get install gstreamer1.0-alsa
