一?videolan-howto-en-html?
該文檔完全描述了VideoLAN?"流"的解決方法.?
VideoLAN?項目包括兩個軟件.?
1)?VLC:以前是視頻流接收的客戶端,但是現在也可以作為服務端工作.
?2)?VLS:視頻服務端,能發送?MPEG-1,?MPEG-2?and?MPEG-4?files,?DVDs,?digital?satellite?channels,?digital?terrestial?television?channels?and?live?videos?on?the?network?in?unicast?or?multicast.?
1.VLC?在REDHAT?下的安裝?
從下面的鏈接中下載?vlc的包和包所需要的庫,把他們都放在同一個目錄.?http://www.videolan.org/vlc/download-redhat.html?
源代碼安裝:?源代碼安裝需要的庫如下:?
libdvbpsi?(compulsory)?,?
mpeg2dec?(compulsory)?,?
libdvdcss?if?you?want?to?be?able?to?read?encrypted?DVDs?,?
libdvdplay?if?you?want?to?have?DVD?menu?navigation?,?
a52dec?if?you?want?to?be?able?to?decode?the?AC3?(i.e.?A52)?sound?format?often?used?in?DVDs?,?
ffmpeg,?libmad,?faad2?if?you?want?to?read?MPEG?4?/?DivX?files?,?
libogg?&?libvorbis?if?you?want?to?read?Ogg?Vorbis?files?.?
2.VLC在命令行下接收流?
Receive?an?unicast?stream?
%?vlc?-vvv?udp:?
Receive?a?multicast?stream?
%?vlc?-vvv?udp:@239.255.12.42?
where?239.255.12.42?is?the?multicast?IP?address?you?want?to?join.?
Receive?an?HTTP/FTP/MMS?stream?Use?one?of?the?following?command?lines:?
%?vlc?-vvv?http://example/stream.xyz?
where?http://example/stream.xyz?is?the?HTTP?address?of?the?stream;?
%?vlc?-vvv?[url=ftp://example/stream.xyz]ftp://example/stream.xyz[/url]?
where?[url=ftp://example/stream.xyz]ftp://example/stream.xyz[/url]?is?the?FTP?address?of?the?stream;?
%?vlc?-vvv?ms://viptvr.yacast.fr/encoderfranceinfo
?where?mms://viptvr.yacast.fr/encoderfranceinfo?is?the?MMS?address?of?the?stream.?
Receive?a?RTP?stream?available?through?RTSP
?%?vlc?-vvv?rtsp://www.hardradio.com/tonbeme.mov?
where?rtsp://www.hardradio.com/tonbeme.mov?is?the?address?of?the?stream.?
Receive?a?stream?described?by?an?SDP?file?
%?vlc?-vvv?http://server.example.org/stream.sdp?
3.VLC在命令行下發送流?
%?vlc?-vvv?video1.xyz?--sout?udp:192.168.0.42?--ttl?12?
???where:?*video1.xyz?is?the?file?you?want?to?stream,?
*192.168.0.42?is?either:?
??????the?IP?address?of?the?machine?you?want?to?unicast?to;?
?????or?the?DNS?name?the?machine?you?want?to?unicast?to;?
????or?a?multicast?IP?address.?
*12?is?the?value?of?the?TTL?(Time?To?Live)?of?your?IP?packets?(which?means?that?the?stream?will?be?able?to?cross?11?routers).?If?you?want?to?stream?the?file?continuously,?add?the?--loop?option.?
4.VLC?高級應用(VLC's?stream?output?(transcoding,?multiple?streaming,?etc...))?
語法:?
??Please?refer?to?the"?command?line?interface"?chapter?of?the?"VLC?user?guide?"to?learn?the?syntax?of?VLC's?stream?output.?
例子:?----編碼方面的例子?
