Rasperry Pi: cvlc“浮点异常”

Question

我正在尝试将rtsp流引导到flv流，以便能够使用vlc在浏览器中显示它。我使用以下命令：

cvlc rtsp://xxx.xxx.xxx.xxx/xxx/xxx :sout='#transcode{vcodec=FLV1,scale=1,acodec=none,deinterlace}:http{mime=video/x-flv,mux=ffmpeg{mux=flv},dst=127.0.0.1:8090/device_1.flv}' :no-sout-standard-sap :ttl=5 :sout-keep :no-audio --video --no-sout-audio

使用它后，将生成以下输出：

我没有使用vlc的经验，因此如果有任何帮助，将不胜感激

我最近也遇到了同样的问题。下面的解决方案不能完全解决vlc问题，但它最终允许我在raspbian上流式传输视频。

使用UV4L的Raspi流

sudo vim /etc/apt/sources.list

将以下行添加到文件中

# for uv4l library
deb http://www.linux-projects.org/listing/uv4l_repo/raspbian/ jessie main
# for old version libssl1.0.0 lib that is a dependency for uv4l-server
deb http://ftp.de.debian.org/debian jessie main 

更新包列表和安装依赖项

sudo apt-get update
sudo apt-get install uv4l uv4l-raspicam uv4l-raspicam-extras uv4l-webrtc

编辑默认配置(可选)，即设置ssl或编码格式等。

sudo vim /etc/uv4l/uv4l-raspicam.conf

最后，启动将在raspberry pi上托管服务器的服务

sudo service uv4l_raspicam start # stop

导航到

您应该会看到UI。
