|
24 |
- |
|
25 |
-WARNING: avserver is unmaintained, largely broken and in need of a |
|
26 |
-complete rewrite. It probably won't work for you. Use at your own |
|
27 |
-risk. |
|
28 |
- |
|
29 |
-avserver is a streaming server for both audio and video. It supports |
|
30 |
-several live feeds, streaming from files and time shifting on live feeds |
|
31 |
-(you can seek to positions in the past on each live feed, provided you |
|
32 |
-specify a big enough feed storage in avserver.conf). |
|
33 |
- |
|
34 |
-This documentation covers only the streaming aspects of avserver / |
|
35 |
-avconv. All questions about parameters for avconv, codec questions, |
|
36 |
-etc. are not covered here. Read @file{avconv.html} for more |
|
37 |
-information. |
|
38 |
- |
|
39 |
-@section How does it work? |
|
40 |
- |
|
41 |
-avserver receives prerecorded files or FFM streams from some avconv |
|
42 |
-instance as input, then streams them over RTP/RTSP/HTTP. |
|
43 |
- |
|
44 |
-An avserver instance will listen on some port as specified in the |
|
45 |
-configuration file. You can launch one or more instances of avconv and |
|
46 |
-send one or more FFM streams to the port where avserver is expecting |
|
47 |
-to receive them. Alternately, you can make avserver launch such avconv |
|
48 |
-instances at startup. |
|
49 |
- |
|
50 |
-Input streams are called feeds, and each one is specified by a <Feed> |
|
51 |
-section in the configuration file. |
|
52 |
- |
|
53 |
-For each feed you can have different output streams in various |
|
54 |
-formats, each one specified by a <Stream> section in the configuration |
|
55 |
-file. |
|
56 |
- |
|
57 |
-@section Status stream |
|
58 |
- |
|
59 |
-avserver supports an HTTP interface which exposes the current status |
|
60 |
-of the server. |
|
61 |
- |
|
62 |
-Simply point your browser to the address of the special status stream |
|
63 |
-specified in the configuration file. |
|
64 |
- |
|
65 |
-For example if you have: |
|
66 |
-@example |
|
67 |
-<Stream status.html> |
|
68 |
-Format status |
|
69 |
- |
|
70 |
-# Only allow local people to get the status |
|
71 |
-ACL allow localhost |
|
72 |
-ACL allow 192.168.0.0 192.168.255.255 |
|
73 |
-</Stream> |
|
74 |
-@end example |
|
75 |
- |
|
76 |
-then the server will post a page with the status information when |
|
77 |
-the special stream @file{status.html} is requested. |
|
78 |
- |
|
79 |
-@section What can this do? |
|
80 |
- |
|
81 |
-When properly configured and running, you can capture video and audio in real |
|
82 |
-time from a suitable capture card, and stream it out over the Internet to |
|
83 |
-either Windows Media Player or RealAudio player (with some restrictions). |
|
84 |
- |
|
85 |
-It can also stream from files, though that is currently broken. Very often, a |
|
86 |
-web server can be used to serve up the files just as well. |
|
87 |
- |
|
88 |
-It can stream prerecorded video from .ffm files, though it is somewhat tricky |
|
89 |
-to make it work correctly. |
|
90 |
- |
|
91 |
-@section What do I need? |
|
92 |
- |
|
93 |
-I use Linux on a 900 MHz Duron with a cheapo Bt848 based TV capture card. I'm |
|
94 |
-using stock Linux 2.4.17 with the stock drivers. [Actually that isn't true, |
|
95 |
-I needed some special drivers for my motherboard-based sound card.] |
|
96 |
- |
|
97 |
-I understand that FreeBSD systems work just fine as well. |
|
98 |
- |
|
99 |
-@section How do I make it work? |
|
100 |
- |
|
101 |
-First, build the kit. It *really* helps to have installed LAME first. Then when |
|
102 |
-you run the avserver ./configure, make sure that you have the |
|
103 |
-@code{--enable-libmp3lame} flag turned on. |
|
104 |
- |
|
105 |
-LAME is important as it allows for streaming audio to Windows Media Player. |
|
106 |
-Don't ask why the other audio types do not work. |
|
107 |
- |
|
108 |
-As a simple test, just run the following two command lines where INPUTFILE |
|
109 |
-is some file which you can decode with avconv: |
|
110 |
- |
|
111 |
-@example |
|
112 |
-./avserver -f doc/avserver.conf & |
|
113 |
-./avconv -i INPUTFILE http://localhost:8090/feed1.ffm |
|
114 |
-@end example |
|
115 |
- |
|
116 |
-At this point you should be able to go to your Windows machine and fire up |
|
117 |
-Windows Media Player (WMP). Go to Open URL and enter |
|
118 |
- |
|
119 |
-@example |
|
120 |
- http://<linuxbox>:8090/test.asf |
|
121 |
-@end example |
|
122 |
- |
|
123 |
-You should (after a short delay) see video and hear audio. |
|
124 |
- |
|
125 |
-WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to |
|
126 |
-transfer the entire file before starting to play. |
|
127 |
-The same is true of AVI files. |
|
128 |
- |
|
129 |
-@section What happens next? |
|
130 |
- |
|
131 |
-You should edit the avserver.conf file to suit your needs (in terms of |
|
132 |
-frame rates etc). Then install avserver and avconv, write a script to start |
|
133 |
-them up, and off you go. |
|
134 |
- |
|
135 |
-@section Troubleshooting |
|
136 |
- |
|
137 |
-@subsection I don't hear any audio, but video is fine. |
|
138 |
- |
|
139 |
-Maybe you didn't install LAME, or got your ./configure statement wrong. Check |
|
140 |
-the avconv output to see if a line referring to MP3 is present. If not, then |
|
141 |
-your configuration was incorrect. If it is, then maybe your wiring is not |
|
142 |
-set up correctly. Maybe the sound card is not getting data from the right |
|
143 |
-input source. Maybe you have a really awful audio interface (like I do) |
|
144 |
-that only captures in stereo and also requires that one channel be flipped. |
|
145 |
-If you are one of these people, then export 'AUDIO_FLIP_LEFT=1' before |
|
146 |
-starting avconv. |
|
147 |
- |
|
148 |
-@subsection The audio and video lose sync after a while. |
|
149 |
- |
|
150 |
-Yes, they do. |
|
151 |
- |
|
152 |
-@subsection After a long while, the video update rate goes way down in WMP. |
|
153 |
- |
|
154 |
-Yes, it does. Who knows why? |
|
155 |
- |
|
156 |
-@subsection WMP 6.4 behaves differently to WMP 7. |
|
157 |
- |
|
158 |
-Yes, it does. Any thoughts on this would be gratefully received. These |
|
159 |
-differences extend to embedding WMP into a web page. [There are two |
|
160 |
-object IDs that you can use: The old one, which does not play well, and |
|
161 |
-the new one, which does (both tested on the same system). However, |
|
162 |
-I suspect that the new one is not available unless you have installed WMP 7]. |
|
163 |
- |
|
164 |
-@section What else can it do? |
|
165 |
- |
|
166 |
-You can replay video from .ffm files that was recorded earlier. |
|
167 |
-However, there are a number of caveats, including the fact that the |
|
168 |
-avserver parameters must match the original parameters used to record the |
|
169 |
-file. If they do not, then avserver deletes the file before recording into it. |
|
170 |
-(Now that I write this, it seems broken). |
|
171 |
- |
|
172 |
-You can fiddle with many of the codec choices and encoding parameters, and |
|
173 |
-there are a bunch more parameters that you cannot control. Post a message |
|
174 |
-to the mailing list if there are some 'must have' parameters. Look in |
|
175 |
-avserver.conf for a list of the currently available controls. |
|
176 |
- |
|
177 |
-It will automatically generate the ASX or RAM files that are often used |
|
178 |
-in browsers. These files are actually redirections to the underlying ASF |
|
179 |
-or RM file. The reason for this is that the browser often fetches the |
|
180 |
-entire file before starting up the external viewer. The redirection files |
|
181 |
-are very small and can be transferred quickly. [The stream itself is |
|
182 |
-often 'infinite' and thus the browser tries to download it and never |
|
183 |
-finishes.] |
|
184 |
- |
|
185 |
-@section Tips |
|
186 |
- |
|
187 |
-* When you connect to a live stream, most players (WMP, RA, etc) want to |
|
188 |
-buffer a certain number of seconds of material so that they can display the |
|
189 |
-signal continuously. However, avserver (by default) starts sending data |
|
190 |
-in realtime. This means that there is a pause of a few seconds while the |
|
191 |
-buffering is being done by the player. The good news is that this can be |
|
192 |
-cured by adding a '?buffer=5' to the end of the URL. This means that the |
|
193 |
-stream should start 5 seconds in the past -- and so the first 5 seconds |
|
194 |
-of the stream are sent as fast as the network will allow. It will then |
|
195 |
-slow down to real time. This noticeably improves the startup experience. |
|
196 |
- |
|
197 |
-You can also add a 'Preroll 15' statement into the avserver.conf that will |
|
198 |
-add the 15 second prebuffering on all requests that do not otherwise |
|
199 |
-specify a time. In addition, avserver will skip frames until a key_frame |
|
200 |
-is found. This further reduces the startup delay by not transferring data |
|
201 |
-that will be discarded. |
|
202 |
- |
|
203 |
-* You may want to adjust the MaxBandwidth in the avserver.conf to limit |
|
204 |
-the amount of bandwidth consumed by live streams. |
|
205 |
- |
|
206 |
-@section Why does the ?buffer / Preroll stop working after a time? |
|
207 |
- |
|
208 |
-It turns out that (on my machine at least) the number of frames successfully |
|
209 |
-grabbed is marginally less than the number that ought to be grabbed. This |
|
210 |
-means that the timestamp in the encoded data stream gets behind realtime. |
|
211 |
-This means that if you say 'Preroll 10', then when the stream gets 10 |
|
212 |
-or more seconds behind, there is no Preroll left. |
|
213 |
- |
|
214 |
-Fixing this requires a change in the internals of how timestamps are |
|
215 |
-handled. |
|
216 |
- |
|
217 |
-@section Does the @code{?date=} stuff work. |
|
218 |
- |
|
219 |
-Yes (subject to the limitation outlined above). Also note that whenever you |
|
220 |
-start avserver, it deletes the ffm file (if any parameters have changed), |
|
221 |
-thus wiping out what you had recorded before. |
|
222 |
- |
|
223 |
-The format of the @code{?date=xxxxxx} is fairly flexible. You should use one |
|
224 |
-of the following formats (the 'T' is literal): |
|
225 |
- |
|
226 |
-@example |
|
227 |
-* YYYY-MM-DDTHH:MM:SS (localtime) |
|
228 |
-* YYYY-MM-DDTHH:MM:SSZ (UTC) |
|
229 |
-@end example |
|
230 |
- |
|
231 |
-You can omit the YYYY-MM-DD, and then it refers to the current day. However |
|
232 |
-note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this |
|
233 |
-may be in the future and so is unlikely to be useful. |
|
234 |
- |
|
235 |
-You use this by adding the ?date= to the end of the URL for the stream. |
|
236 |
-For example: @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}. |
