mjpg-streamer input plugin: input_raspicam
MJPEG Streamer with raspicam input plugin (based on raspistill mmal source code)
Discussion / Questions / Help
Probably best in this thread http://www.raspberrypi.org/phpBB3/viewtopic.php?f=43&t=45178
Instructions
If you ran the basic build, you can run from the mjpeg streamer experimental folder with:
export LD_LIBRARY_PATH=.
./mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so"
You can specify options, like in raspivid:
export LD_LIBRARY_PATH=.
./mjpg_streamer -o "output_http.so -w ./www" -i "input_raspicam.so -x 1280 -y 720 -fps 15 -ex night"
It does support upto 1080p 30fps, but the bandwidth produced would be more than the usb bus (and therefore ethernet port / wifi dongle) can provide. 720p 15fps is a good compromise.
Here's some help for this input plugin:

The following parameters can be passed to this plugin:
[-fps | --framerate]...: set video framerate, default 5 frame/sec
[-x | --width ]........: width of frame capture, default 640
[-y | --height]........: height of frame capture, default 480
[-quality].............: set JPEG quality 0-100, default 85
[-usestills]...........: uses stills mode instead of video mode
[-preview].............: enable full screen preview
-sh : Set image sharpness (-100 to 100)
-co : Set image contrast (-100 to 100)
-br : Set image brightness (0 to 100)
-sa : Set image saturation (-100 to 100)
-ISO : Set capture ISO
-vs : Turn on video stabilisation
-ev : Set EV compensation
-ex : Set exposure mode (see raspistill notes)
-awb : Set AWB mode (see raspistill notes)
-ifx : Set image effect (see raspistill notes)
-cfx : Set colour effect (U:V)
-mm : Set metering mode (see raspistill notes)
-rot : Set image rotation (0-359)
-stats : Compute image stats for each picture (reduces noise)
-drc : Dynamic range compensation level (see raspistill notes)
-hf : Set horizontal flip
-vf : Set vertical flip
---------------------------------------------------------------
Some of the camera options like ISO may not work due to it not working in the mmal-libs.
Video mode is the default as it allows much smoother video (higher framerates). Stills mode allows you to use the full-frame of the sensor, but has a max framerate of around 8fps, probably less. Use stills mode with low FPS (e.g. 1 or 2).
In order to have preview output shown on the raspi screen add the -preview option.
This should run indefinitely. ctrl-c closes mjpeg streamer and raspicam gracefully.
