34 <p>Recently I have spent some time evaluating the multimedia browser
35 plugins available in Debian Lenny, to see which one we should use by
36 default in Debian Edu. We need an embedded video playing plugin with
37 control buttons to pause or stop the video, and capable of streaming
38 all the multimedia content available on the web. The test results and
39 notes are available on
40 <a href="http://wiki.debian.org/DebianEdu/BrowserMultimedia">the
41 Debian wiki</a>. I was surprised how few of the plugins are able to
42 fill this need. My personal video player favorite, VLC, has a really
43 bad plugin which fail on a lot of the test pages. A lot of the MIME
44 types I would expect to work with any free software player (like
45 video/ogg), just do not work. And simple formats like the
46 audio/x-mplegurl format (m3u playlists), just isn't supported by the
47 totem and vlc plugins. I hope the situation will improve soon. No
48 wonder sites use the proprietary Adobe flash to play video.</p>
49
50 <p>For Lenny, we seem to end up with the mplayer plugin. It seem to
51 be the only one fitting our needs. :/</p>

74 <p>This weekend we had a small developer gathering for Debian Edu in
75 Oslo. Most of Saturday was used for the general assemly for the
76 member organization, but the rest of the weekend I used to tune the
77 LTSP installation. LTSP now work out of the box on the 10-network.
78 Acer Aspire One proved to be a very nice thin client, with both
79 screen, mouse and keybard in a small box. Was working on getting the
80 diskless workstation setup configured out of the box, but did not
81 finish it before the weekend was up.</p>
82
83 <p>Did not find time to look at the 4 VGA cards in one box we got from
84 the Brazilian group, so that will have to wait for the next
85 development gathering. Would love to have the Debian Edu installer
86 automatically detect and configure a multiseat setup when it find one
87 of these cards.</p>

110 <p>The <a href="http://www.nuug.no/">Norwegian Unix User Group</a> is
111 recording our montly presentation on video, and recently we have
112 worked on improving the quality of the recordings by mixing the slides
113 directly with the video stream. For this, we use the
114 <a href="http://dvswitch.alioth.debian.org/">dvswitch</a> package from
115 the Debian video team. As this require quite one computer per video
116 source, and NUUG do not have enough laptops available, we need to
117 borrow laptops. And to avoid having to install extra software on
118 these borrwed laptops, I have wrapped up all the programs needed on a
119 bootable USB stick. The software required is dvswitch with assosiated
120 source, sink and mixer applications and
121 <a href="http://www.kinodv.org/">dvgrab</a>. To allow this setup to
122 work without any configuration, I've patched dvswitch to use
123 <a href="http://www.avahi.org/">avahi</a> to connect the various parts
124 together. And to allow us to use laptops without firewire plugs, I
125 upgraded dvgrab to the one from Debian/unstable to get one that work
126 with USB sources. We have not yet tested this setup in a production
127 setup, but I hope it will work properly, and allow us to set up a
128 video mixer in a very short time frame. We will need it for
129 <a href="http://www.goopen.no/">Go Open 2009</a>.</p>
130
131 <p><a href="http://www.nuug.no/pub/video/bin/usbstick-dvswitch.img.gz">The
132 USB image</a> is for a 1 GB memory stick, but can be used on any
133 larger stick as well.</p>

156 <p>As part of the work we do in <a href="http://www.nuug.no">NUUG</a>
157 to publish video recordings of our monthly presentations, we provide a
158 page with embedded video for easy access to the recording. Putting a
159 good set of HTML tags together to get working embedded video in all
160 browsers and across all operating systems is not easy. I hope this
161 will become easier when the &lt;video&gt; tag is implemented in all
162 browsers, but I am not sure. We provide the recordings in several
163 formats, MPEG1, Ogg Theora, H.264 and Quicktime, and want the
164 browser/media plugin to pick one it support and use it to play the
165 recording, using whatever embed mechanism the browser understand.
166 There is at least four different tags to use for this, the new HTML5
167 &lt;video&gt; tag, the &lt;object&gt; tag, the &lt;embed&gt; tag and
168 the &lt;applet&gt; tag. All of these take a lot of options, and
169 finding the best options is a major challenge.</p>
170
171 <p>I just tested the experimental Opera browser available from <a
172 href="http://labs.opera.com">labs.opera.com</a>, to see how it handled
173 a &lt;video&gt; tag with a few video sources and no extra attributes.
174 I was not very impressed. The browser start by fetching a picture
175 from the video stream. Not sure if it is the first frame, but it is
176 definitely very early in the recording. So far, so good. Next,
177 instead of streaming the 76 MiB video file, it start to download all
178 of it, but do not start to play the video. This mean I have to wait
179 for several minutes for the downloading to finish. When the download
180 is done, the playing of the video do not start! Waiting for the
181 download, but I do not get to see the video? Some testing later, I
182 discover that I have to add the controls="true" attribute to be able
183 to get a play button to pres to start the video. Adding
184 autoplay="true" did not help. I sure hope this is a misfeature of the
185 test version of Opera, and that future implementations of the
186 &lt;video&gt; tag will stream recordings by default, or at least start
187 playing when the download is done.</p>
188
189 <p>The test page I used (since changed to add more attributes) is
190 <a href="http://www.nuug.no/aktiviteter/20090113-foredrag-om-foredrag/">available
191 from the nuug site</a>. Will have to test it with the new Firefox
192 too.</p>
193
194 <p>In the test process, I discovered a missing feature. I was unable
195 to find a way to get the URL of the playing video out of Opera, so I
196 am not quite sure it picked the Ogg Theora version of the video. I
197 sure hope it was using the announced Ogg Theora support. :)</p>
