+*************** FFserver live broadcast server *****************
+
+0) Introduction
+
+ffserver is a streaming server for both audio and video. It supports
+several live feeds, streaming from files and time shifting on live
+feeds (you can seek to positions in the past on each live feed,
+provided you specify a big enough feed storage in ffserver.conf).
+
+1) Quick help
+
+- First you must ensure that your grab system is OK. Verify with
+ 'xawtv' that your TV card is tuned on a correct video source.
+
+- Try with ffmpeg that you can record correctly. For example:
+
+ ffmpeg /tmp/a.mpg
+
+will record a ten seconds mpeg file from your TV card and audio
+card. Use for example the mpegtv player or MPlayer to view the created
+MPEG file.
+
+- Launch ffserver on your PC with the sample config file:
+
+ ffserver -f doc/ffserver.conf
+
+- Verify with your browser that ffserver is working correctly. For
+ that purpose, explore: http://localhost:8090/stat.html .
+
+- Now launch ffmpeg to do real time encoding :
+
+ ffmpeg http://localhost:8090/feed1.ffm
+
+- Then, use your favorite players to see each generated stream:
+
+ mtvp http://localhost:8090/test1.mpg
+
+ mpg123 http://localhost:8090/test.mp2
+
+ netscape http://localhost:8090/test.swf
+
+ realplayer http://localhost:8090/test.rm
+
+ etc...
+
+ Note that ffserver generate multiple streams in multiple formats AT
+ THE SAME TIME. It should be able to handle hundreds of users at the
+ same time if you internet connection is fast enough.
+
+- Now you can configure ffserver for your real needs. Edit the
+ ffserver.conf file to use only the formats you want. Read the ffmpeg
+ documentation (ffmpeg.txt) to learn more about the codec and format
+ stuff.
+
+- Report any bug you find (and the fix if you have it!).
+
+2) URL Format
+
+ ffserver supports that you seek in some formats. The syntax is to
+ add a '?' option to the URL. Only the 'date' option is supported.
+
+ The date format is [YYYY-MM-DDT][[HH:]MM:]SS[.m...] (clost to ISO
+ date format). For live streams, the date is absolute and give in
+ GMT. If the day is not specified, the current day is used.
+
+ example:
+
+ mpg123 http://localhost:8090/test.mp2?date=10:00
+
+ play the stream starting at 10:00 AM GMT today.
+
+ mpg123 http://localhost:8090/test.mp2?date=2001-06-23T23:00
+
+ is also a valid date.
+
+ For file streams, the date is relative to the start of the file. No
+ day can be specified.
+
