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"
The config file for the ffserver is:
HTTPPort 8080
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 50000

An other streaming format would also be a possibility but I didn't know which are possible for live-streaming.

I want to live stream video from h.264/h.265 IP camera to browser with little to no delay and in decent quality (Full HD). I know there are couple of questions like this one but the answers seem to be either incomplete or outdated. So far I've tried ffmpeg and ffserver and had some success with them, but there are problems:
When I stream to mjpg the quality isn't great, if I use webm quality is better but there is significant delay (aprox. 5 seconds), probably due to transcoding from h264 to vp9. How can I improve it? Is it possible to stream h264 without transcoding it to different format? Are there any better solutions than ffserver and ffmpeg?
Here is the config I've used for mjpg:
ffmpeg -rtsp_transport tcp -i rtsp://rtsp_user:Rtsp_pass#192.168.3.83:554/Streaming/Channels/101 -q:v 3 http://localhost:8090/feed3.ffm
on ffserver:

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 fighting with this thing all day, googling like a madman the entire time. What am I doing wrong? Any help will be welcomed enthusiastically.
These are my notes as I'm currently working through a similar process:

Makesure webcam.sh contains:

Run the following:

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
CustomLog -

File /tmp/feed.ffm # video stream.
FileMaxSize 512K
</Feed>
<Stream test.h264> # Output stream URL definition
Feed feed.ffm # Feed from which to receive video
Format rtp
# Video settings
VideoCodec libvpx
VideoSize 720x576 # Video resolution
VideoFrameRate 60 # Video FPS
AVOptionVideo flags +global_header # Parameters passed to encoder
# (same as ffmpeg command-line parameters)
AVOptionVideo cpu-used 0
AVOptionVideo qmin 10
AVOptionVideo qmax 42
AVOptionVideo quality good
AVOptionAudio flags +global_header
PreRoll 15
StartSendOnKey
VideoBitRate 400 # Video bitrate
NoAudio
</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?
I grab the image from my camera using ffmpeg and the following command:
ffmpeg -y -f vfwcap -r 25 -i 0 http://10.172.180.235:8090/feed2.ffm
and on other machine (with the ip mentioned above) I have the ffserver running with the following config file:
HttpPort 8090
HttpBindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 3000

And that works, I can stream video in flv over http... But now I would like to use rtmp, becase I want to display the live stream on my webpage with some player. I wanted to use the video.js, but it seems like in the latest versions it doesn't support live video any more... I found mediaelement.js, but to stream live content there I need the rtmp protocol, so that's the cause of my question.
Thanks for your help
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

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
