**Update**

An updated version of this post is –>here (Part 3) <–.

Or to stream via Motion, check out this blog post !

*****

There have been quite a few people wanting to stream a webcam from the Raspberry Pi.
If all you want is to view a webcam stream, without any motion detection, then you’ve come to the right post.
Otherwise, I’ll have a blog post up about motion later on for motion detection.

This guide should get you to the point where you can view the webcam stream from another machine via a web browser, or a media player capable of viewing mjpeg streams – e.g. VLC.

1. Compiling FFMpeg

First thing we need to do is to get a version of ffmpeg that can stream. The version that comes with the current version of Raspbian and Debian have issues streaming, so the sources from deb-multimedia are needed. All the below commands are run as root. If you are not running as root, prepend sudo to all the commands.

**Update**
If you need sound for ffmpeg, you will need to also install the libasound2-dev package which enables ALSA.
– Thanks to fbutler for this

Add the following lines into /etc/apt/sources.list
deb-src http://www.deb-multimedia.org sid main deb http://www.deb-multimedia.org wheezy main non-free
Run apt-get update
Run apt-get install deb-multimedia-keyring
Remove the second line from /etc/apt/sources.list
deb http://www.deb-multimedia.org wheezy main non-free
Run apt-get source ffmpeg-dmo
You should now have a folder called ffmpeg-dmo-0.11 <-- The version will change as time goes by.
Change the directory to the folder containing the source. e.g. cd ffmpeg-dmo-0.11
Run ./configure to setup the source.
Run make && make install to compile and install ffmpeg
if you are not running as root like I am, then you will need to run the above command with sudo

2. Configuring ffmpeg

Once ffmpeg is installed, we need to create a configuration file to enable ffmpeg to stream to ffserver.
ffserver is what will host the stream.

We need to create a configuration file for ffserver, we will place it in /etc/ and call it ffserver.conf
Port 80 BindAddress 0.0.0.0 MaxClients 10 MaxBandwidth 50000 NoDaemon <Feed webcam.ffm> file /tmp/webcam.ffm FileMaxSize 10M </Feed>
<Stream webcam.mjpeg> Feed webcam.ffm Format mjpeg VideoSize 640x480 VideoFrameRate 10 VideoBitRate 2000 VideoQMin 1 VideoQMax 10 </Stream>
The last stanza defines the size of the stream, and bitrate. If the parameters don’t suit each other, then the stream will not be smooth.
Next, the following command needs to be put into a .sh file. This will allow you to start streaming by just running the .sh file. Let’s call it webcam.sh and put it in /usr/sbin as the file needs to be run as root.
ffserver -f /etc/ffserver.conf & ffmpeg -v verbose -r 5 -s 640x480 -f video4linux2 -i /dev/video0 http://localhost/webcam.ffm
Once the .sh file has been created, and the above code has been placed into it, you need to make the file executable by running chmod +x /usr/sbin/webcam.sh

3. Start Streaming

Once the shell script and configuration file has been created, you can start streaming by running /usr/sbin/webcam.sh
When you run it, you should start seeing lines like this
** 1 dup!2 fps= 5 q=2.6 size= 51136kB time=00:06:56.40 bitrate=1006.0kbits/s dup=359 drop=0
This means that ffmpeg is now streaming, and you should be able to access the stream via the web address of http://<YOUR WEBCAM SERVER>/webcam.mjpeg

** Update of sorts – I continue my webcam experimentation here

In 2.2 i think you have an error in the code. should it not be http://localhost:81/webcam.ffm

  I actually changed it slightly from the post you followed 🙂
  at the top – bind port defines which port ffserver is listening on – so changing that to 80 negates the need to define a port when you’re accessing the stream

Hello, thank you for your guide. I ran into some problems, and I’m hoping you can help me. I’ve been trying to stream from my Pi + webcam for ages now, without success.

First thing I noticed were some errors in the make stage, like “libavcodec/flacdec.c:340:43: warning: ‘d’ may be used uninitialized in this function [-Wuninitialized]”.

Finally, when all is done, when I try to access the stream via browser (I’m using Chrome), it tries to download a file named webcam.mjpeg.mjpeg 😀

I also have a .asf feed, but when I use VLC to access it, in the console of ffserver/ffmpeg I get:

Codec for stream 0 does not use global headers but container format requires global headers
Codec for stream 1 does not use global headers but container format requires global headers

and VLC fails.

Any help here would be very much appreciated 🙂 Oh, I’m using a Mac.

Cheers!

  Have you tried using VLC to view the mjpeg stream to see if that works ?

    Yes. I’ve got rid of those warnings/errors too, but still no deal.
    
    VLC doesn’t open any stream at all … asf, rm, swf, whatever I configure ffserver with.
    I’ve noticed that when I try to access the stream, in the status page of ffserver it states WAIT_FEED for my connection.
    
    I’ve also noticed in other people posts that ffserver reports the input as a connection, but in mine that line doesn’t show. Maybe it’s getting trouble reading my device?
    
    I’m not trying with a Logitech C270. With what webcam did you succeed?
    
    Thanks for your time!

      Does /dev/ contain video0 ?

        Can you run this command, and see if the file it outputs contains video ?
        
        ffmpeg -v verbose -r 5 -s 640×480 -f video4linux2 -i /dev/video0 temp.avi
        
        This should create the temp.avi file, and hopefully it should contain some video.
        Let it run for 10 or so seconds, then hit “q” to make it stop, then view the video.
        
        It should tell us whether ffmpeg is actually working or not.

        Hi! I had the same problem… I can ran ffserver and ffmpeg commands successfull, but when i tried to get the stream at VLC, i got error like canno't access or something like that, and stat.html contains WAIT_FEED.
        
        I have no solution for this, but it’s just one time get working successfully, and i didn’t do anything for it. Now it’s working, hope you get same 🙂

  Hi
  
  I had similar issues to you as well when I first started this.
  This line holds the clue
  The v4l2 frame is 65496 bytes, but 614400 bytes are expected
  
  I found that I had my bitrate set too low. Try setting it higher and see how you go.
  If you could also pastebin your configuration file, that would be helpful also.

      keeps changing to “The v4l2 frame is * bytes, but 614400 bytes are expected”
      * = wildcard

      Are you using a Webcam with compression… I’m having the same problem with a Logitech Quickcam and get:
      
      [video4linux2,v4l2 @ 0x26f04b0] Buffer len [0] = 118784 != 307200
      
      There is a comment about MJPEG compression on the video4linux2 wiki:

        I think I have the same problem with the logitech webcam, from what I’ve read it’s plausible that the cam is spitting out compressed MJPEG and V4L can’t handle this. Anyone found a way to ask the camera to spit out uncompressed MJPEG?

        My webcam driver was chaging the resolution to somthing weird (I can’t remember what exactly, I’m in school so I’ll check later) so I changed the res in my /usr/sbin/webcam.sh file and the ffserver.conf file.I’ve got a treally old “creative” one with a really bad resolution.

        Try and use v4l2-ctl or uvcdynctrl to detect the resolutions that your webcam can use and try using those resolutions ?
        I know some webcams will force a certain fps or resolution so that could be an issue ?

Thanks a lot! This worked straight away with a Logitech Pro 9000 webcam.

But would you happen to know how to make ffmpeg read mjpeg data from the webcam instead of raw uncompressed data? I’d like to stream the mjpeg directly – that would lessen the system load a lot.

Hey, I really appreciate you made this tutorial. Thank you.
But even though I followed every single step of it, it gives me:

The webcam, Logitech Quickcam 9000 Pro, works out fine, since I recorded an AVI and played it back.
What am I doing wrong?

        Can you try a different browser to access http://192.168.2.139/webcam.mjpeg ?
        
        Also, when you access using vlc, make sure you have http:// at the beginning or it won’t work.

        Firefox and Internet Explorer just keep on loading forever when opening the stream. But everytime I start loading it with some browser the byte-count of webcam.mjpeg goes up a little and a new connection with the state WAIT_FEED comes up in the lowest table.

        Can you paste the whole entire output from when you start the command until it starts streaming ?

        I got it fixed now. I put up a new installation of wheezy. Apparently the typo with “webam” completely confused my little pi… but thanks a lot! Your answers gave me a lot of troubleshooting-exercise 😀

        Goodo ! Glad to hear you got it going 🙂
        It just occurred to me that maybe you still had an ffserver instance running in the background. Perhaps that was causing issues as well !

I also tried changing the port since it sometimes comes up with Address already in use.

  Already in use, because you have running ffserver from webcam.sh

    The webcam.sh file is meant to be run to start streaming.
    If the ffmpeg process dies however, either the ffserver process needs to be killed and then webcam.sh run again, or you need to run ffmpeg with the same parameters as the ones in webcam.sh

  Do you have any other http server running ? Apache or lighthttpd ?
  By default they use the same port as the webcam.sh script. You’ll need to change the port that the script uses in order to get it to stream.
  
  And thanks for reading 🙂

        or maybe try vga ?
        also, is ffserver setup to use http://localhost/webcam.mjpeg ?
        Need to change that to port 8080 also – i.e. http://localhost:8080/webcam.mjpeg
        ffserver will need to be setup to use webcam.mjpeg as well for the stream input.

Hi
Many thanks for the walk-through.
Have compiled, installed and configured ffmpeg as per instructions. All seemed to go well. When I try and run webcam.sh I see the configuration followed by:

[video4linux2,v412 @ 0x173e520] [3]Capabilities: 5000001
[video4linux2,v412 @ 0x173e520] ioctl set time per frame(1/5) failed
/dev/video0: Input/output error

It does appear to open port 80 though as further attempts to run webcam.sh reveal that port 80 is in use.
This is the only thing installed on a clean wheezy image (which has been updated).
Any suggestions gratefully recieved.
Many thanks
Dave

  Can’t say I know what that means…
  Perhaps try a make clean and then do a make && make install as root ?

Followed the instructions to the letter, but I’m getting the following when attempting to stream the cam:

[NULL @ 0x2ce1520] Requested output format ‘video4linux2’ is not a suitable output format

Ideas? qv4l2 shows the webcam and I can see the content there, so I know the camera is working and detected.

Every time I try to post my code, I get a 404 page not found error.

So instead, I’ll post the URL of the file in my Dropbox

  Not sure why you get the 404 but i’ll look into it. In regards to the script, it needs to be run as root or sudo in order for it to open up the lower ports. Higher ports do not have the same limitation though.

OK, I moved everything to port 8080. I issue webcam.sh and it prints what you see below and totally hangs the SSH session.

      What’s the command you’re running to start streaming ?
      ioctl(VIDIOC_DQBUF): Input/output error
      Not sure what that means but that seems to be the issue…
      
      Try recording to a file via ffmpeg and see if that works.

I am using a “Logitech, Inc. HD Webcam C910” with Pi. When I run the script webcam.sh, all seems to run well, but when I access the stream via the web address (with Firefox) I obtain this message “This feed is already being received” What happens? I try too with VLC, but it doesn’t work.

This is my console output:

I’m not quite Sure but I think you have to apt-get update once again after 1.3 (apt-get install deb-multimedia-keyring) ..

        Same thing I guess, check to see if swap space / file is enabled.
        Did you copy the files from the old SD card or is this a new download of the source ?
        Maybe it needs a make clean if they’re old files.

Thanks for this great walkthrough! I got my pi up and running with a quickcam 9000. The only thing is that I get 1-2 fps average, and there’s a 3-10 second delay, depending on the different settings I’ve tried. Is there any way to improve this? I’m hoping to rig up my pi with a battery and long-range wifi adapter and use it for aerial views from an RC glider plane.

I’ve tried:
ffmpeg -loglevel info -r 10 -vcodec mjpeg -s 320×240 -f video4linux2 -i /dev/video0 http://localhost/webcam.ffm

But it gives me: /dev/video0: Could not find codec parameters

And i’ve also tried this that I found somewhere:
ffmpeg -r 25 -s 320×240 -f video4linux2 -i /dev/video0 -f rawvideo http://localhost/webcam.ffm

But it gives: av_interleaved_write_frame(): Connection reset by peer.

Any help would be appreciated, thanks!

  Thanks for reading !
  
  If you can check the capabilities of the webcam via v4l2-ctrl or uvcdynctrl to see what’s native to the webcam, you may be able to use optimised settings for lower cpu usage.
  
  Otherwise you may have to just try and tweak the settings as all webcams are different so what works for me may not work for you.
  Also try bumping up the loglevel to verbose so you can see if the cam is running into any buffer over flow errors or anything which may be slowing things down.
  
  You could also try using the tool mjpeg-streamer and see how you go with that.

  Are you running ffmpeg with the verbose paramter ? Try with the debug flag also to see if more information comes up.
  
  Sounds like the fps you’re trying to use is not supported. Some webcams are picky about these things, so you might need tl try a different fps
  
  Also you can try to run just the ffmpeg part of the webcam.sh file but replace http://localhost/webcam.ffm with temp.avi and see what that says.

    running in verbose mode generates the same results. outputting to temp.avi also outputs the same results as below, stopping at the same place. You can see below that I’ve switched framrate to 30 – but it still freezes at the same point.

        V4l2-ctl is a program that normally needs installing via apt-get. It shows you the capabilities of your webcam.
        
        I would try and install that, then use it to find out what resolutions and fps the cam supports.

      Ok, made some learnings…
      
      sudo apt-get install v4l-utils
      
      Gets the v4l2-ctl – and
      
      v4l2-ctl --all
      
      gets the info about the webcam.

        I’m still getting this error every few minutes…
        
        “The v4l2 frame is 367 bytes, but 153600 bytes are expected
        /dev/video0: Invalid data found when processing input
        No more output streams to write to, finishing.”
        
        Here’s the pastebin of my v4l2-ctl: http://pastebin.com/NqGxTjtP
        
        Should I tune my output better? or is there a way to ignore or force ffserver to accept these wonky frame byte numbers?

        I get the same issue depending on the webcam. I haven’t been able to resolve this issue as of yet so my workaround was to have a script run every few minutes to check to see whether ffmpeg was running and if it wasn’t, it would run ffmpeg again

        What does your script look like that checks and runs again?

        Something along the lines of this – I’m writing it from the top of my head so this probably won’t work, but you can always give it a shot
        Hopefully I still have the proper script that I was using at home, otherwise I’ll just write up another one 🙂
        #!/bin/bash
        ffmpeg=`ps aux | grep ffmpeg | wc -l` if [[ $ffmpeg -ne 1 ]]; do run ffmpeg command that you want to use fi
        
        ^ and then schedule that to run every minute or 5 minutes or whatever via cron.

        I think the bigger solution is here:
        http://web.archiveorange.com/archive/v/yR2T4eDRCIV1ZzyRoBve
        
        I just don’t know what I’m supposed to do with it…
        
        Can you make sense of it?

        October 30, 2012 at 4:05 pm
        
        That looks like some patching that was applied to the ffmpeg code.
        Being from 3 years ago, I would assume that the necessary changes have already made it into the ffmpeg code base, but I could be mistaken.
        I’ll have a closer look when I get home.
        
        Edit – Actually I think that the code on that page has definitely been applied as ffmpeg can capture mjpeg streams from webcams.

        Thanks so much for your help, we just want to include a tag here that says “ignore errors,” or skip “errors”.
        
        I’ve been hanging out in the ffmpeg irc room in freenode and I still don’t have the answer.
        
        I’m sure between us we’ll figure it out.

      Can you paste the output when you run the script file ? and also the script file itself as well ?
      Perhaps it’s not catching the error when it can’t read the log file.

On what version of whezzy are you running this?

I have bin struggling for days to get it fixed. I always get an error at “sudo make && make install”
Last time I got this error message: “libavformat/bit.d:1: *** missing separator. Stop.”
Other times, something different…
I’m running this from the ffmpeg source folder.

Anyway, tried to ignore the error (worth trying: :)) and continue, but when I’m trying to run webcam.sh I get the fallowing error:

” /usr/sbin/webcam.sh: line 1: ffserver: command not found
/usr/sbin/webcam.sh: line 1: ffmpeg: command not found “

  You may need to download the source again, sounds like the version of the source you have may have missing things.

Hey Lagz great tutorial I’ve been reading through and decided to try it out myself (after spending a week figuring out that I had to do “sudo make && sudo make install” in order to get past step 9 :p ) I just have one problem with it

After I get everything working I find that the fps of my stream is very poor (1-3 fps) for a resolution of 320×240

frame= 111 fps=1.7 q=1.6 size= 424kB time=00:00:22.20 bitrate= 153.5kbits/s

I’ve checked and my webcam can support mjpeg up to 30fps on that resolution but I can’t seem to make it run faster, I even removed ‘VideoFrameRate’ to check if that command is even being noticed and the same happened. The only thing that changes this is if I completely remove (I’ve tried increasing it too with no change) “-r 5” in which the fps shoots up to 20+ but there’s a lot of dup errors and the stream still looks poor fps wise most of the time with some welcome spikes in fps.

Any ideas on what could be wrong?

  That seems to be an issue with some webcams.
  Have you tried an intermediate value for -r ? like say 10 or 15 ?
  Also, what bitrate have you got set in the ffserv config file ?
  
  Also, what do you mean by dup errors ?
  
  Edit – After a quick google, try adding -vsync 0 to the command line and see how you go.
  Edit 2 – I have also edited the post with some hopefully better instructions now lol.

    I’ve managed to get it to work with -r set to 30, it seems that my webcam doesn’t like to update frames unless there is actual activity in the frame. Still sticks to 10fps but I can’t complain 🙂

  If you can see /dev/video0 then the driver is already present. Have you got a gui installed ? Perhaps try using guvcview and see if that can view your webcam ?

Hi can someone help me i have followed the instructions without to much difficulty bet i now get this odd error message
Missing audio stream which is required by this ffm

And the ffserver.conf file is exactly as the one at the start of this post.

This is the output on my command line

can someone tell me either how to fix this without sound or by telling me how to make the sound work if it really wants to use the sounds it can i was wanting to try and make the sound thing work after the stream is up and stable.
The kicker is i have had it working for a day then after a pi reboot it did this 🙁

  Is your configuration file *exactly* how it is there ? Or did WordPress strip some tags that were in there initially ?
