<p>vdr2qiv documented</p> <p><b>New page</b></p><div>==Description==<br /> <br /> This plugin has been written for the following scenario: The VDR is connected in the &quot;usual&quot; way to a TV, but<br /> the TV also has a VGA input to which the videocard of the VDR is connected, running an X server.<br /> <br /> One would like to display images using the X server, but keeping all the other functionality the old way.<br /> The idea of this plugin is to act as a gateway: When loaded, the plugin starts an external image viewer<br /> and forwards commands received from the remote to the viewer.<br /> <br /> Warning: This plugin is a total hack. I only document it here in the hope that it will be useful for someone<br /> anyway. To get it running some tinkering is required.<br /> <br /> ==Download==<br /> <br /> All required files can be found in this archive: http://www.jan.vornberger.net/sonstiges/vdr2qiv.tar.gz<br /> <br /> ==Installation==<br /> <br /> It should be possible to compile and load the plugin like every VDR plugin. The plugin expects to find<br /> a wrapper script called vdr2qiv.sh in /usr/local/bin/. If you don't like that path, you can change it in<br /> vdr2qiv.c. Once the plugin is loaded, it starts this wrapper script which in turn starts the external<br /> image viewer.<br /> <br /> For the external image viewer Qiv is used, which the wrapper script expects to find in /usr/local/bin<br /> under the name &quot;qiv_vdr&quot;.<br /> <br /> The image viewer has been patched by me as well (as I said, quite a hack *g*) to be able to receive the<br /> commands from the plugin. To make this possible the process signal USR2 is used, as well as a pipe in<br /> /video/vdr2qiv.pipe. This pipe has to be created with &quot;mkfifo /video/vdr2qiv.pipe&quot;. Should you want to change<br /> these paths as well, changes in the plugin as well as the qiv patch are needed.<br /> <br /> The Qiv version I used can be download here: http://www.klografx.net/qiv/download/qiv-2.0-src.tgz<br /> The archive contains a patch that can be applied with &quot;patch &lt; qiv-2.0_vdr.patch&quot;. Qiv can then be compiled<br /> and the binary copied over to /usr/local/bin/qiv_vdr.<br /> <br /> To be able to open the image viewer an X servers needs to be running and the wrapper script<br /> needs to have the required rights to start and display Qiv.<br /> <br /> After loading the plugin it displays a small help site which documents how to control qiv from the remote.<br /> <br /> ==Conclusion==<br /> <br /> Yes, it's a total hack and absolutely tailored to my system (hardcoded paths and the like). But maybe someone<br /> wants to realize a similar project and this can be a starting point. I'd be glad to hear from someone, so maybe<br /> you could drop me a quick line at jan@uos.de. That way I'd also know if I should document future hacks or if<br /> they are just to much focused on my specific situation to be of any use for someone else.</div>
