ffmpeg 으로 스트리밍 서버만들기(링크)

우분투 8.04에서 Logitech Quickcam Pro 4000으로 스트리밍 서버 만드는 방법이다.

$ ffserver -f ./ffserver.conf $ ffmpeg -y -f video4linux -r 30 -s 160x120 -i /dev/video0 http://localhost:8090/feed1.ffm 웹브라우저 http://xxx.xxx.xxx.xxx:8090/stream.asf [링크 : http://sound79.tistory.com/105]

머.. ffmpeg 홈페이지의 ffserver 문서와 다를 내용은 그리 없지만

As a simple test, just run the following two command lines where INPUTFILE is some file which you can decode with ffmpeg: ./ffserver -f doc/ffserver.conf & ./ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm At this point you should be able to go to your Windows machine and fire up Windows Media Player (WMP). Go to Open URL and enter http://<linuxbox>:8090/test.asf

아무튼.. wmv 중요한건 저게 아니라 /etc/ffserver.conf 파일의 내용일 듯 하다.


ffmpeg 홈페이지의 ffserver.conf 예제파일

# Port on which the server is listening. You must select a different # port from your standard HTTP web server if it is running on the same # computer. Port 8090 # Address on which the server is bound. Only useful if you have # several network interfaces. BindAddress 0.0.0.0 # Number of simultaneous HTTP connections that can be handled. It has # to be defined *before* the MaxClients parameter, since it defines the # MaxClients maximum limit. MaxHTTPConnections 2000 # Number of simultaneous requests that can be handled. Since FFServer # is very fast, it is more likely that you will want to leave this high # and use MaxBandwidth, below. MaxClients 1000 # This the maximum amount of kbit/sec that you are prepared to # consume when streaming to clients. MaxBandwidth 1000 # Access log file (uses standard Apache log file format) # '-' is the standard output. CustomLog - # Suppress that if you want to launch ffserver as a daemon. NoDaemon ################################################################## # Definition of the live feeds. Each live feed contains one video # and/or audio sequence coming from an ffmpeg encoder or another # ffserver. This sequence may be encoded simultaneously with several # codecs at several resolutions. <Feed feed1.ffm> # You must use 'ffmpeg' to send a live feed to ffserver. In this # example, you can type: # # ffmpeg http://localhost:8090/feed1.ffm # ffserver can also do time shifting. It means that it can stream any # previously recorded live stream. The request should contain: # "http://xxxx?date=[YYYY-MM-DDT][[HH:]MM:]SS[.m...]".You must specify # a path where the feed is stored on disk. You also specify the # maximum size of the feed, where zero means unlimited. Default: # File=/tmp/feed_name.ffm FileMaxSize=5M File /tmp/feed1.ffm FileMaxSize 200K # You could specify # ReadOnlyFile /saved/specialvideo.ffm # This marks the file as readonly and it will not be deleted or updated. # Specify launch in order to start ffmpeg automatically. # First ffmpeg must be defined with an appropriate path if needed, # after that options can follow, but avoid adding the http:// field #Launch ffmpeg # Only allow connections from localhost to the feed. ACL allow 127.0.0.1 </Feed> ################################################################## # Now you can define each stream which will be generated from the # original audio and video stream. Each format has a filename (here # 'test1.mpg'). FFServer will send this stream when answering a # request containing this filename. <Stream test1.mpg> # coming from live feed 'feed1' Feed feed1.ffm # Format of the stream : you can choose among: # mpeg       : MPEG-1 multiplexed video and audio # mpegvideo  : only MPEG-1 video # mp2        : MPEG-2 audio (use AudioCodec to select layer 2 and 3 codec) # ogg        : Ogg format (Vorbis audio codec) # rm         : RealNetworks-compatible stream. Multiplexed audio and video. # ra         : RealNetworks-compatible stream. Audio only. # mpjpeg     : Multipart JPEG (works with Netscape without any plugin) # jpeg       : Generate a single JPEG image. # asf        : ASF compatible streaming (Windows Media Player format). # swf        : Macromedia Flash compatible stream # avi        : AVI format (MPEG-4 video, MPEG audio sound) Format mpeg # Bitrate for the audio stream. Codecs usually support only a few # different bitrates. AudioBitRate 32 # Number of audio channels: 1 = mono, 2 = stereo AudioChannels 1 # Sampling frequency for audio. When using low bitrates, you should # lower this frequency to 22050 or 11025. The supported frequencies # depend on the selected audio codec. AudioSampleRate 44100 # Bitrate for the video stream VideoBitRate 64 # Ratecontrol buffer size VideoBufferSize 40 # Number of frames per second VideoFrameRate 3 # Size of the video frame: WxH (default: 160x128) # The following abbreviations are defined: sqcif, qcif, cif, 4cif, qqvga, # qvga, vga, svga, xga, uxga, qxga, sxga, qsxga, hsxga, wvga, wxga, wsxga, # wuxga, woxga, wqsxga, wquxga, whsxga, whuxga, cga, ega, hd480, hd720, # hd1080 VideoSize 160x128 # Transmit only intra frames (useful for low bitrates, but kills frame rate). #VideoIntraOnly # If non-intra only, an intra frame is transmitted every VideoGopSize # frames. Video synchronization can only begin at an intra frame. VideoGopSize 12 # More MPEG-4 parameters # VideoHighQuality # Video4MotionVector # Choose your codecs: #AudioCodec mp2 #VideoCodec mpeg1video # Suppress audio #NoAudio # Suppress video #NoVideo #VideoQMin 3 #VideoQMax 31 # Set this to the number of seconds backwards in time to start. Note that # most players will buffer 5-10 seconds of video, and also you need to allow # for a keyframe to appear in the data stream. #Preroll 15 # ACL: # You can allow ranges of addresses (or single addresses) #ACL ALLOW <first address> # You can deny ranges of addresses (or single addresses) #ACL DENY <first address> # You can repeat the ACL allow/deny as often as you like. It is on a per # stream basis. The first match defines the action. If there are no matches, # then the default is the inverse of the last ACL statement. # # Thus 'ACL allow localhost' only allows access from localhost. # 'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and # allow everybody else. </Stream> ################################################################## # Example streams # Multipart JPEG #<Stream test.mjpg> #Feed feed1.ffm #Format mpjpeg #VideoFrameRate 2 #VideoIntraOnly #NoAudio #Strict -1 #</Stream> # Single JPEG #<Stream test.jpg> #Feed feed1.ffm #Format jpeg #VideoFrameRate 2 #VideoIntraOnly ##VideoSize 352x240 #NoAudio #Strict -1 #</Stream> # Flash #<Stream test.swf> #Feed feed1.ffm #Format swf #VideoFrameRate 2 #VideoIntraOnly #NoAudio #</Stream> # ASF compatible <Stream test.asf> Feed feed1.ffm Format asf VideoFrameRate 15 VideoSize 352x240 VideoBitRate 256 VideoBufferSize 40 VideoGopSize 30 AudioBitRate 64 StartSendOnKey </Stream> # MP3 audio #<Stream test.mp3> #Feed feed1.ffm #Format mp2 #AudioCodec mp3 #AudioBitRate 64 #AudioChannels 1 #AudioSampleRate 44100 #NoVideo #</Stream> # Ogg Vorbis audio #<Stream test.ogg> #Feed feed1.ffm #Title "Stream title" #AudioBitRate 64 #AudioChannels 2 #AudioSampleRate 44100 #NoVideo #</Stream> # Real with audio only at 32 kbits #<Stream test.ra> #Feed feed1.ffm #Format rm #AudioBitRate 32 #NoVideo #NoAudio #</Stream> # Real with audio and video at 64 kbits #<Stream test.rm> #Feed feed1.ffm #Format rm #AudioBitRate 32 #VideoBitRate 128 #VideoFrameRate 25 #VideoGopSize 25 #NoAudio #</Stream> ################################################################## # A stream coming from a file: you only need to set the input # filename and optionally a new format.

아무튼 적절한 코덱을 지원하는 동영상을 찾아서 테스트 해봐야 하겠지만,
해상도는 16의 배수, 프레임은 1이상 이어야 하는 것으로 보인다.
