Question

我已经尝试了许多应该通过VLC使用RTSP流式传输RPi相机然后使用VLC在Windows计算机上播放流而没有成功的示例。

例如在我的RPi 3上更新了Jessie（约20170820）我进入终端窗口：raspivid -o - -t 0 -w 1920 -h 1080 -fps 30 -b 1000000 | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264

我从一个四分之一（https://forum.qnap.com/viewtopic.php?t=97676）以及写的：

Hi, with VLC I just need to open the network stream with this string: "rtsp://192.168.1.58:8554". I also tried with port 554 and managed to add a path (I tried with path /live.sdp), but while the stream opens with no problems in VLC, i have no luck with SS. Obviously when I changed config I changed both cvlc parameters on the Pi and vlc connection string on my pc
Yeah, I'm using Generic RTSP (I have SS 5.0.1, can't find SS Pro)

I didn't check if it was using UDP or TCP, i leaved them to default values. If I'd know what codec to use I could specify it in cvlc, but since I wasn't able to find what is supported by SS and what is not, I tried default with h264.

当我尝试使用VLC时，我会收到带有消息的VLC错误对话框：

Your input can't be opened:
VLC is unable to open the MRL 'rtsp://192.168.1.58:8554'. Check the log for details.

不确定接下来要尝试什么。

Answer 1

我在这个论坛上找到了我的问题的答案： https://www.raspberrypi.org/forums/viewtopic.php?t=132116 Solution here

答案是在rtsp流中添加文件名。

自：

raspivid -o - -e -t 0 -p 0,0,640,480 -w 680 -h 480 -fps 30 -g 30 -ih -pf baseline -md 4 -k -b 1000000 | cvlc -A-vvv alsa，none -v stream：/// dev / stdin --sout＆＃39; #rtp {sdp = rtsp：//：8554}＆＃39; ：解复用器= H264

要：

raspivid -o - -e -t 0 -p 0,0,640,480 -w 680 -h 480 -fps 30 -g 30 -ih -pf baseline -md 4 -k -b 1000000 | cvlc -A-vvv alsa，none -v stream：/// dev / stdin --sout＆＃39; #rtp {sdp = rtsp：//：8554 / x}＆＃39; ：解复用器= H264

在这里，我会尝试大胆一点。 raspivid -o - -e -t 0 -p 0,0,640,480 -w 680 -h 480 -fps 30 -g 30 -ih -pf baseline -md 4 -k -b 1000000 | cvlc -A-vvv alsa，none -v stream：/// dev / stdin --sout＆＃39; #rtp {sdp = rtsp：//：8554 ** / x **}＆＃39; ：解复用器= H264

尝试使用VLC流式传输Raspberry Pi相机。无法在Windows上获取VLC播放流
