Downloading VLC for streaming camera

[Martyparty]

I want to live stream from my Raspberry Pi, and I'm trying to download VLC in the terminal, by writing

sudo apt-get install vlc, but its unable to fetch some archives. How can i solve this problem?

And is VLC-player the best to stream in? Does anyone have any example codes to control the camera?

Thank you so much for any answers

Which camera ? What do you mean by "control the camera" ?

Did you do "sudo apt update" and "sudo apt upgrade" first ?

This is the camera i bought "Camera Module Board 5MP Wide Angle Video Cam 1080p 720p for Raspberry Pi",
yes I have tried both the update and upgrade. Could a problem be that my internet was not working on the raspberry?

Yes you need an active internet connection to update / install packages.

Please can you post a URL link to what Camera you purchased !

I found out that there was a problem with the internet connection, so that's why I could not install vlc. Now I have managed, and I tried entering this code

raspivid -o - -t 0 -n | cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/}' :demux=h264

which I found at this page http://www.raspberry-projects.com/pi/pi ... vlc-player. I get several debugs, and two errors:
"PulseAudio server connection failure: Connection refused" and "Invalid PCR value in ES_OUT_SET_(GROUP_)PCR !"

Is this a problem? Or should the live stream still work?
Not sure how to view the RTSP stream?
Where should I write this code " rtsp://###.###.###.###:8554/ " With my Raspberry pi IP address.

Is it necessary to download more libraries? And how do I do this?

> Where should I write this code " rtsp://###.###.###.###:8554/ " With my Raspberry pi IP address.

In a VLC running on another computer for example.

When trying to run "raspivid -o - -t 0 -hf -w 800 -h 400 -fps 24 |cvlc -vvv stream:///dev/stdin --sout '#standard{access=http,mux=ts,dst=:8160}' :demux=h264" I also get these messeges:

core stream error: cannot pre fill buffer
core input warning: cannot create a stream_t from access

What does it mean? And is it critical?

What is your vlc version?
vlc -v

Just asking since I only got streaming working with 2.0.3. I can't get it work with 2.2.4, but of course it may work if done properly.

That geos in vlc player under network connection. Although I just learned that if you just want to remotely see your camera you can see the preview/camera output easily just with realvnc connect - Knowing that trick sooner would have saved me hours of banging my head trying to get streaming happening...in the new realvnc connect, somewhere under troubleshooting is an option to enable the "experimental something framebuffer video layers something something." Anyway..find it, check it, then start raspivid with the tags "-t 0" (which means turn on forever) "-o -" (which means save no file...unless you want to save video, I just use mine to see where my robot is) and whatever size and window location tags you want. Then the preview is just there on your client machine.

i have a little RPi zero, assigned 192.168.1.2 running:

Code: Select all

/usr/bin/raspivid -o - -t 0 -hf -w 640 -h 360 -fps 25 | /usr/bin/cvlc -vvv stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554}' :demux=h264

on my Macbook Air, running OS X, i use this URL in firefox:

rtsp://192.168.1.2:8554/

it launches vlc automagically for me... alternatively, i can launch vlc, click File->Open Network and type in the above URL... this also works under Ubuntu, IOS, etc.

hope this helps!

Could not open this, should I have seen your camera?

Thank you so much everyone! Now I managed to live stream to my computer. I am just wondering if anyone knows of something to do to minimize the delay?

And is there anyone who has any ideas on how I can turn it on and off, when I'm going to control the raspberry with a servomotor on my vehicle. Is there a way you can control that over vlc or something?

Thank you very much for mentioning VNC CONNECT, for my application streaming video from a birdbox over Wifi is up til now the best solution and with very low latency. Works with RPi3 and RPi0.
