    <p>We are trying to get Gstreamer working on a DM368 Leopardboard*, we've successfully persuaded it to create a test video (videotestsrc), encode it, and dump it into a file.</p> <p>The pipe that worked is:</p> <pre><code>gst-launch -v videotestsrc num-buffers=100 ! queue ! ffenc_mpeg4 bitrate=800000 ! ffmux_mp4 ! filesink location=video_test.mp4 </code></pre> <p>The next step is to modify the pipe to stream the testcard over the network, to be viewed on a PC with VLC using something like <strong>rtsp://ip_addr:port/streamname</strong> but the documentation on how to do this seems quite thin on the ground (and often outdated), and the examples seem to blur source code and command line ways of doing it.</p> <p>I'll freely admit that >50% of the problem is our lack of familiarity with Gstreamer &amp; its various parts, I've always found that if I have a working example to start from I can poke it with sticks and work out the rest from there.</p> <p>I've got this far:</p> <pre><code>gst-launch -v videotestsrc ! queue ! ffenc_mpeg4 bitrate=800000 ! rtpmp4vpay ! tcpserversink host=&lt;PC_ip&gt; port=5000 </code></pre> <p>Which seems to make <em>something</em> happen in VLC (using <strong>tcp://board_ip:port</strong>)- it seems to think there's something going on (doesn't throw an error) but doesn't play/show anything. When I break (^C) the gst process, VLC notices.</p> <p>So, basically - any guidance/feedback would be great, a working one-liner would be fantastic.</p> <p><em>Edited to add:</em> Yes I see the test_video.c example, but that's compiling a special program to do something which looks like it should be possible to just invoke from the command line to prove the concept.</p> <pre><code>* = Linux version 2.6.32-17-ridgerun /CPU: ARM926EJ-S </code></pre>

    1. COThere is a c example that seems to do it here, but doesn't really explain how it's used: http://cgit.freedesktop.org/gstreamer/gst-rtsp-server/tree/examples/test-video.c

    2. COgst-rtsp-server has test-launch example, you can specify the encoding pipeline. The server code is very small since it uses most of the gstreamer's rtsp implementation.

    3. COYes, I'm looking at the gst example code, but it seems to me there should be some way of invoking gstreamer from the command line to stream a video just to prove that it's possible & working.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
