But is there anyone willing to take the task to developed either new plugin or update text2skin? Is text2skin even maintained anymore - let alone thought to be updated by the author to vectorized direction?

If support for a high res/color OSD is present in the VDR core, why would you need a plugin to provide anything to any other plugin? Unless you mean a plugin that handles different ways of supplying the OSD such as the different techniques previously mentioned (xml, html, etc etc)? ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Quoting Torgeir Veimo torg...@pobox.com: Why not go all the way and implement an opengl rendered OSD with vdpau? This would of course require information from vdr in a slightly different form; ie. semantically instead of pixels. I'd suggest trying to get the OSD information as HTML from VDR, then allowing the frontend to render it in any way it deems suitable, with fancy animation, transition effects, icons etc. This might also make it easier to implement text-only OSD, eg for terminal connections. I don't think that HTML is a good idea, it should be more general. I would suggest XML with SVG for graphics and animations. Together with XSLT it would be easy to have different themes.

Gerald I second this proposal (esp. SVG for resolution scalability). XML with SVG provides a lot of possibilities. If you want to have animations etc. then PNG-format provides means for this as well. OpenGL does not provide sufficient added value for this type of usage, IMO, but it will make things way more complicated. Full colour OSD with above mentioned means would provide real nice platform for OSD developers. There is at least one drawback with this idea and that's additional CPU power requirements. Maybe simple XML and SVG would not be too CPU hungry after all.. Pasi ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Let's all keep our fingers crossed tight for that.
