v4l2rtspserver
This is an streamer feed from :
- an Video4Linux device that support H264, HEVC, JPEG, VP8 or VP9 capture.
- an ALSA device that support PCM S16_BE, S16_LE, S32_BE or S32_LE
The RTSP server support :
- RTP/UDP unicast
- RTP/UDP multicast
- RTP/TCP
- RTP/RTSP/HTTP
The HTTP server support (available using -S option for capture format that could be muxed in Transport Stream):

Dependencies
- liblivemedia-dev License LGPL > live.2012.01.07 (need StreamReplicator)
- libv4l2cpp Unlicense
- liblog4cpp5-dev License LGPL (optional)
If liblog4cpp5-dev is not present, a simple log using std::cout is used.
- libasound2-dev Licence LGPL (optional)
If libasound2-dev is not present in the build environment, there will have no audio support.
- libssl-dev (optional)
If libssl-dev is not present rtsps/srtp will not be available
Usage
./v4l2rtspserver [-v[v]] [-Q queueSize] [-O file] \
[-I interface] [-P RTSP port] [-p RTSP/HTTP port] [-m multicast url] [-u unicast url] [-M multicast addr] [-c] [-t timeout] \
[-r] [-s] [-W width] [-H height] [-F fps] [device1] [device2]
-v : verbose
-vv : very verbose
-Q length: Number of frame queue (default 10)
-O output: Copy captured frame to a file or a V4L2 device
RTSP options :
-I addr : RTSP interface (default autodetect)
-P port : RTSP port (default 8554)
-p port : RTSP over HTTP port (default 0)
-U user:password : RTSP user and password
-R realm : use md5 password 'md5(<username>:<realm>:<password>')
-u url : unicast url (default unicast)
-m url : multicast url (default multicast)
-M addr : multicast group:port (default is random_address:20000)
-c : don't repeat config (default repeat config before IDR frame)
-t secs : RTCP expiration timeout (default 65)
-S[secs] : HTTP segment duration (enable HLS & MPEG-DASH)
-x <sslkeycert> : enable SRTP
-X : enable RSTPS
V4L2 options :
-r : V4L2 capture using read interface (default use memory mapped buffers)
-w : V4L2 capture using write interface (default use memory mapped buffers)
-B : V4L2 capture using blocking mode (default use non-blocking mode)
-s : V4L2 capture using live555 mainloop (default use a separated reading thread)
-f : V4L2 capture using current capture format (-W,-H are ignored)
-fformat : V4L2 capture using format (-W,-H are used)
-W width : V4L2 capture width (default 640)
-H height: V4L2 capture height (default 480)
-F fps : V4L2 capture framerate (default 25, 0 disable setting framerate)
-G <w>x<h>[x<f>] : V4L2 capture format (default 0x0x25)
ALSA options :
-A freq : ALSA capture frequency and channel (default 44100)
-C channels: ALSA capture channels (default 2)
-a fmt : ALSA capture audio format (default S16_LE)
device : V4L2 capture device and/or ALSA device (default /dev/video0)
When audio support is not present, ALSA options are not printed running with -h argument.
Authentification is enable when almost one user is defined. You can configure credentials :
-
using plain text password:
-U foo:bar -U admin:admin
-
using md5 password:
-R myrealm -U foo:$(echo -n foo:myrealm:bar | md5sum | cut -d- -f1) -U admin:$(echo -n admin:myrealm:admin | md5sum | cut -d- -f1)
It is possible to compose the RTSP session is different ways :
- v4l2rtspserver /dev/video0 : one RTSP session with RTP video capturing V4L2 device /dev/video0
- v4l2rtspserver ,default : one RTSP session with RTP audio capturing ALSA device default
- v4l2rtspserver /dev/video0,default : one RTSP session with RTP audio and RTP video
- v4l2rtspserver /dev/video0 ,default : two RTSP sessions first one with RTP video and second one with RTP audio
- v4l2rtspserver /dev/video0 /dev/video1 : two RTSP sessions with an RTP video
- v4l2rtspserver /dev/video0,/dev/video0 : one RTSP session with RTP audio and RTP video (ALSA device associatd with the V4L2 device)
Build
Using Raspberry Pi Camera
This RTSP server works with Raspberry Pi camera using :
Using v4l2loopback
For camera providing uncompress format v4l2tools can compress the video to an intermediate virtual V4L2 device v4l2loopback:
/dev/video0 (camera device)-> v4l2compress -> /dev/video10 (v4l2loopback device) -> v4l2rtspserver
This workflow could be set using :
modprobe v4l2loopback video_nr=10
v4l2compress -fH264 /dev/video0 /dev/video10 &
v4l2rtspserver /dev/video10 &
Playing HTTP streams
When v4l2rtspserver is started with ‘-S’ arguments it also give access to streams through HTTP.
These streams could be played :
* for MPEG-DASH with :
MP4Client http://..../unicast.mpd
* for HLS with :
vlc http://..../unicast.m3u8
gstreamer-launch-1.0 playbin uri=http://.../unicast.m3u8
It is now possible to play HLS url directly from browser :
There is also a small HTML page that use hls.js.
Using Docker image
You can start the application using the docker image :
docker run -p 8554:8554 -it mpromonet/v4l2rtspserver
You can expose V4L2 devices from your host using :
docker run --device=/dev/video0 -p 8554:8554 -it mpromonet/v4l2rtspserver
The container entry point is the v4l2rtspserver application, then you can :
-
get the help using :
docker run -it mpromonet/v4l2rtspserver -h
-
run the container specifying some paramters :
docker run --device=/dev/video0 -p 8554:8554 -it mpromonet/v4l2rtspserver -u "" -H640 -W480
