Raspberry pi UV4L（RPi）-与Janus WebRTC举行会议

我尝试了“与Janus WebRTC网关的音频/视频会议”页面。除了将“观看来自其他参与者的实时音频和视频”设置为“是”之外，我将所有内容都保留为默认设置。然后，我从Chrome浏览器（我的笔记本电脑）加入了Janus视频室页面的“”。我可以在页面上看到我笔记本电脑摄像头的流媒体，但没有RPi的流媒体。虽然它显示了RPI摄像机每秒变化的流波特率，但它不显示视频。此外，当我说话时，我会听到来自RPi扬声器的声音，因此RPi肯定已连接，但无法正确传输视频。有什么想法吗？提前谢谢

这也是我的raspicam.conf：

# This file contains the default values of SOME of all the available
# options for the UV4L core module, the raspicam driver, and the
# streaming server front-end.
#
# This file is referenced by the 'uv4l_raspicam' init script.
# Alternatively, it can be passed as argument to
# the '--driver-config-file' driver option and/or to the
# '--config-file' option of uv4l.
#
# Please refer to the 'uv4l', 'uv4l-raspicam' and 'uv4l-server' manual
# pages for all the valid options and values or for more informations
# about their meaning.

# NOTE: for multi argument options you must specify one arg per line,
# e.g --min-object-size 80 120 becomes:
# min-object-size = 80
# min-object-size = 120
