I want embed a webcam stream (From geovision video server) into a website. Unfortunately only the rtsp stream gives direct access to the video data.
I tried a bunch of different variants. With this version I got no errors:
openRTSP -b 50000 -w 352 -h 288 -f 5 -v -c -u admin password rtsp://xxxxxx.dyndns.org:8554/CH001.sdp | \
ffmpeg -r 5 -b 256000 -f mp4 -i - http://127.0.0.1:8090/feed1.ffm
Unfortunately I get no video. Sometimes I see a single frame of the webcam, but no livestream.
This is my ffserver.conf
Port 8090
BindAddress 0.0.0.0

What am I doing wrong? THe test.swf seems to load forever...
Tried something like this with vlc and it worked for me...
vlc.exe -I http -vv camURL :sout=#transcode{vcodec=h264,vb=0,scale=0,acodec=mp4a,ab=128,channels=2,samplerate=44100}:http{mux=ffmpeg{mux=flv},dst=addr:availablePort}
camurl is the url of the camera....
addr is the address where you want the httpstream to be sent to...
availablePort is the port where you want the httpstream to be sent to
You need to insert quotes in right way:
cvlc rtsp://192.168.13.162:554/ :sout='#transcode{vcodec=FLV1,vb=2048,fps=25,scale=1,acodec=none,deinterlace}:http{mime=video/x-flv,mux=ffmpeg{mux=flv},dst=0.0.0.0:5555/}' :no-sout-standard-sap :ttl=5 :sout-keep :no-audio --rtsp-caching 10200 --video --no-sout-audio --udp-caching=30000 --http-caching=5000

I wish to capture an rtsp stream and convert it to an mjpeg (over http) stream using ffmpeg. I am running Ubuntu 20. I have searched and searched for the solution, and mostly find:
a) solutions requiring ffserver (deprecated)
b) solutions converting from mjpeg to rtsp
c) solutions converting from rtsp to hls (nginx, wowza, etc...) which doesn't work in my application. I need http output as mjpeg.
d) vlc - which does work but requires way too much of my available processor (80%)
e) rtsp2mjpg - github project which I installed, but could not get to work and can't get any support.
I am not an ffmpeg expert, so if someone could step me through an ffmpeg solution to this, if it exists, I'd really appreciate it.
I've very recently solved this myself, after finding the exact same things as you. The two parts are you need are (1) ffmpeg conversion in a script, and (2) something like lighttpd+cgibin or nginix+fastcgi to serve it over http/https. I don't expect you'll be able to do much better in terms of CPU use than vlc, though.
This bash script will do the ffmpeg conversion to MJPEG, and send the output to stdout. Put this in lighttpd's cgi-bin folder (/var/www/cgi-bin for me). Call it something like "webcamstream", and adjust the rtsp:// URL to suit your camera:
#!/bin/bash
echo "Content-Type: multipart/x-mixed-replace;boundary=ffmpeg"
echo "Cache-Control: no-cache"
echo ""
ffmpeg -i "rtsp://192.168.60.13:554/user=admin&password=SECRET&channel=1&stream=0.sdp" -c:v mjpeg -q:v 1 -f mpjpeg -an -
Enable cgi-bin for lighttpd:
ln -s /etc/lighttpd/conf-available/10-cgi.conf /etc/lighttpd/conf-enabled/10-cgi.conf
..and then adjust lighttp's cgi-bin configuration (/etc/lighttpd/conf-enabled/10-cgi.conf) as shown below. The stream-response-body setting is important, as it'll both stop the stream when the client disconnects, and also avoid having lighttpd try to buffer the entire infinite stream before sending anything to the client.
server.modules += ( "mod_cgi" )
$HTTP["url"] =~ "^/cgi-bin/" {
server.stream-response-body = 2
cgi.assign = ( "" => "" )
alias.url += ( "/cgi-bin/" => "/var/www/cgi-bin/" )
}
Make the cgi-bin script executable and restart lighttpd:
chmod +x /var/www/cgi-bin/webcamstream
systemctl restart lighttpd
...and that should be it. You can then access the MJPEG stream at a URL like this, where the last part is your script's name:
http://serveraddress/cgi-bin/webcamstream
I've written it up in more detail here: Converting RTSP to HTTP on demand
As far as I can tell, you can't avoid taking the CPU hit of the conversion -- the format/encoding of RTSP vs. MJPEG frames are different. I reduced my CPU load by configuring the camera to reduce the source's framerate and resolution until it was an acceptable load on ffmpeg. You can change the resolution and framerate with ffmpeg arguments as well, but it would still have to decode the full frames first and do the work of resizing.
The paths above are on Debian, so you may need to adjust them to suit your Ubuntu system.

If your want to run FFMPEG in console background, try to use -nostdin to FFMPEG or run in terminal multiplexer like SCREEN or TMUX.
I want to preface this question with the fact that I am very very new to ffmpeg and even newer to ffserver.
I cannot, for the life of me, get this thing going.
I get:
"Too large number of skipped frames 882933314374 > 60000"
Also, ffplay gives me first frame is no keyframe

I've been playing for the last couple of days with FFMpeg and FFServer as I am considering them as candidates for livestreaming between an embedded device(with an integrated HD camera) and various clients(smartphones).
I've managed to achieve the stream using with the following config for FFServer:
HTTPPort 1234
RTSPPort 1235
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 512000 # Maximum bandwidth per client
# set this high enough to exceed stream bitrate

AVOptionVideo qmax 42
AVOptionVideo quality good
AVOptionAudio flags +global_header
PreRoll 15
StartSendOnKey
VideoBitRate 400 # Video bitrate

</Stream>
And the following FFMpeg command to send the stream to FFServer:
ffmpeg -rtbufsize 2100M -f dshow -i video="Integrated Camera" -vcodec libx264 http://127.0.0.1:1234/feed.ffm
I also have a simple Android client that plays the RTSP stream using the following URL:
rtsp://mylocalnetworkip:1235/test.h264
But now I am trying to achieve a P2P connection between the embedded device and a smartphone. This has to be over the internet(not in the LAN) and capable to achieve UDP hole punching (such as Skype does for p2p video-calling).
Is this achievable with ffmpeg alone?
Can ffmpeg integrate with a Stun/Turn server such as Coturn to bypass symmetric NATs?
At the moment I'm setting up a screen-sharing platform with the opensource tool ffmpeg / ffserver. At the beginning of the sharing everything is fine. After around 1 1/2 minutes I get the following exception in the output.
[flv # 0x3a47aa0] rc buffer underflow
[flv # 0x3a47aa0] max bitrate possibly too small or try trellis with large lmax or increase qmax
I've tried to set an verry high lmax & qmax but this hasn't changed any thing.Additionally I've tried to increase the bitrate , the buffersize and the bitrate.
I use the following command with ffmpeg:
ffmpeg -f x11grab -s 1920x1080 -r 20 -i :0.0+1680,0 "http://localserver.de:8080/input1.ffm"

An other streaming format would also be a possibility but I didn't know which are possible for live-streaming.
I'm following a guide to live WebM streaming through FFMpeg / FFServer and running into an interesting error. I have tried using a DirectShow webcam source, and also an existing WebM (finite length) video using -vcodec copy. Initially, both will manage to connect to the FFServer (I can see the POST 200 OKs to /feed1.ffm), and maybe even send a frame or two, but then FFMpeg crashes with av_interleaved_write_frame(): Unknown error. (Meanwhile, FFServer appears to be fine.)
This appears to be an unusual variant of the error - normally it's more common to get, say, av_interleaved_write_frame(): I/O error (which indicates file corruption). Has anyone seen this error, and better yet, can anyone tell me how to fix it?
FFMpeg commands
ffmpeg -re -i univac.webm -vcodec copy -acodec copy -f webm http://[my server]/feed1.ffm
ffmpeg -f dshow -i video="[my dshow source]" -f webm http://[my server]/feed1.ffm
FFserver command
ffserver -f ffserver.conf
ffserver.conf
This is only a slight variation in the one provided in the aforementioned guide.

This is probably caused by using different versions of ffmpeg and ffserver.
Try to use the same version. They should work without a problem.
In addition, use only libav or ffmpeg, because they are probably not quite compatible with each other.
The connection was establish by tcp and after I get the error on the client 'av_interleaved_write_frame(): Unknown error'. And I get 'Connection timed out' on the server.
For me, I found that I had an other process listened on the same port that ffmpeg was configured to used on the client.
to check used ports command:
(windows) netstat -a -b
(ubuntu) netstat -a -p
I used a custom ffmpeg inside a folder. The command used 'ffmpeg' used the wrong ffmpeg. Then I change it to './ffmpeg'.
