우분투 8.04에서 Logitech Quickcam Pro 4000으로 스트리밍 서버 만드는 방법이다.
머.. ffmpeg 홈페이지의 ffserver 문서와 다를 내용은 그리 없지만
아무튼.. wmv 중요한건 저게 아니라 /etc/ffserver.conf 파일의 내용일 듯 하다.
ffmpeg 홈페이지의 ffserver.conf 예제파일
아무튼 적절한 코덱을 지원하는 동영상을 찾아서 테스트 해봐야 하겠지만,
해상도는 16의 배수, 프레임은 1이상 이어야 하는 것으로 보인다.

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 & 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.

| # 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.
