There's a big "Note" in <a href="https://www.mythtv.org/wiki/Osd_subtitle.xml" target="_blank">https://www.mythtv.org/wiki/Osd_subtitle.xml</a> that for the "teletext" family, the only part of osd_subtitle.xml currently used is the font name. This restriction (or more accurately, why it's not yet implemented) is for a few reasons:</div><div><br></div><div>1. The teletext commands are pretty specific about setting foreground and background colors (and whether the background is transparent), making it hard to devise a way to selectively control some of the attributes.</div><div><br></div><div>2. Teletext has this interactive feature that other subtitle families lack.</div><div><br></div><div>3. Teletext has non-textual "mosaics" which are like low-res graphics.</div><div><br></div><div>That said, if the only customization you want (other than font choice) is to change the transparency level of subtitles marked as non-transparent, that would be much easier to fit into the existing model. To hack it in the source code by hand, look in teletextscreen.cpp in TeletextScreen::SetBackgroundColor() for this line:</div><div> m_bgColor.setAlpha((ttcolor & kTTColorTransparent) ? 0x00 : 0xff);<br></div><div>and change the 0xff value to 128 or whatever you like.</div><div><br></div><div>Going forward, it seems like background alpha, text shadow, and text outline may be properties that would make total sense to draw overrides from osd_subtitle.xml. Maybe other properties as well.</div><span><font color="#888888"><div><br></div><div>Jim</div></font></span></div></div></div>
