HOWTO video stream from webcam through internet with ffmpeg(우분투 웹캠서버 만들기)

1)First we have to install ffmpeg (http://ffmpeg.mplayerhq.hu/)(ffmpeg 설치)

Code:

sudo apt-get install ffmpeg

2)Back up ffserver config file.(안전을 위해 백업)

Code:

3)Begin new ffserver config file. (this config was taken from http://www.webmasterworld.com/video/3514671.htm and edited by me)(설정파일만들기)

Code:

sudo gedit /etc/ffserver.conf

paste into file lines below.(아래코드를 붙여 넣고)

Code:

Port 8090
# bind to all IPs aliased or not
BindAddress 0.0.0.0
# max number of simultaneous clients
MaxClients 1000
# max bandwidth per-client (kb/s)
MaxBandwidth 10000
# Suppress that if you want to launch ffserver as a daemon.
NoDaemon 

<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 5M
</Feed> 

# FLV output - good for streaming
<Stream test.flv>
# the source feed
Feed feed1.ffm
# the output stream format - FLV = FLash Video
Format flv
VideoCodec flv
# this must match the ffmpeg -r argument
VideoFrameRate 15
# generally leave this is a large number
VideoBufferSize 80000
# another quality tweak
VideoBitRate 200
# quality ranges - 1-31 (1 = best, 31 = worst)
VideoQMin 1
VideoQMax 5
VideoSize 352x288
# this sets how many seconds in past to start
PreRoll 0
# wecams don't have audio
Noaudio
</Stream> 

# ASF output - for windows media player
<Stream test.asf>
# the source feed
Feed feed1.ffm
# the output stream format - ASF
Format asf
VideoCodec msmpeg4
# this must match the ffmpeg -r argument
VideoFrameRate 15
# generally leave this is a large number
VideoBufferSize 80000
# another quality tweak
VideoBitRate 200
# quality ranges - 1-31 (1 = best, 31 = worst)
VideoQMin 1
VideoQMax 5
VideoSize 352x288
# this sets how many seconds in past to start
PreRoll 0
# wecams don't have audio
Noaudio
</Stream>

4)Start ffserver. Open terminal.

Code:

ffserver

in ffserver config file you can delete line “NoDaemon” to run ffserver as daemon.

5)Start ffmpeg video stream.

Code:

ffmpeg -r 15 -s 352x288 -f video4linux -i /dev/video0 http://localhost:8090/feed1.ffm

If there is no any errors. its done )

Now you can watch the video.
Open your favorite player and open url http://localhost:8090/test.flv or http://localhost:8090/test.asf.

If you whant to watch your stream from another computer with windows media player:
type mms://<ip adress of ffserver machine>:8090/test.asf in IE

Also you can encode video to swf, mpeg and other formats . Read ffmpeg documentation.

If your internet connection is slow, you have make VideoFrameRate lower(1-5).

For streaming to flash player (swf)(플래쉬 플레이어로 보기위해)

add this lines to the end of ffserver.conf

Code:

<Stream test.swf>
Feed feed1.ffm
Format swf
VideoCodec flv
VideoFrameRate 2
VideoBufferSize 80000
VideoBitRate 100
VideoQMin 1
VideoQMax 5
VideoSize 352x288
PreRoll 0
Noaudio
</Stream>

Now you have another stream to test.sfw file then create <any name>.html file
Add this lines to it

Code:

<EMBED src="http://<ip adress of ffserver machine>:8090/test.swf" width=640 height=480 type="application/x-shockwave-flash"></EMBED>
