RE: [vdr] Improving DXR3 OSD

So > it never got beyond polling and experimental guessing :-( Yes... But what I was really after was to do the same thing for the OSD data. The amount of OSD data is a lot less then for the video, and you could make assumptions (like 10x) for the time it will take to transfer it, and it still wouldn't be a problem. But, as far as I know, this hasn't been tested, and I don't know if it's possible (depends on the internal method dxr3 uses to create the osd). Teemu

Now that I re-read what you wrote... I'm still using 0.7.2 (networked) so the cause for this must be something else. My guess is it is a xine dxr3 output module related problem. I don't remember it when I first experimented with software decoding to X11... Teemu

OSD sometimes (usually) disappears on video stream change (e.g. when aborting record playback back to recordings list), and only comes back after a change in OSD (e.g. move cursor up/down in listing). Would it be possible to send OSD e.g. every 1 second (behind configuration option perhaps) even if it not changed, and would it help in this case? This may be a problem related to xine dxr3 output only. Teemu

Improving DXR3 OSD
by Rantanen Teemu 18 Apr '05

18 Apr '05

I've been thinking about the following idea for few weeks now. I'm not sure if it's possible to implement, but it's interesting thought though. The idea is: is there an OSD frame buffer somewhere inside the DXR3, and would it be possible to write OSD data directly into it (without constructing dvd-compatible "osd-stream", which is the cause of all problems as far as I can see). I really don't know if this is technically possible at all, but I saw at some page (which I cannot find anymore) a program, which wrote pictures (=video) directly into DXR3 frame buffer (i.e. decoded video outside of DXR3 and wrote rgb or yu12 (or whatever format was required) directly into the frame buffer inside DXR3).

If you can find the program *with* source It must have been here: http://www-c.informatik.uni-hannover.de/~hunold1/linux/dxr3/ but nothing is there anymore, or at least not right now. I could still find this on the google cache, and stored a copy to my homepage: http://tvr.dy.fi/dxr3fb_readme_txt.htm And, this only mentions about writing to video frame buffer. I don't know if OSD frame buffer exists. Teemu

Hi, has anyone got a working vdr compatible channels.conf file they could share with me for uk-PontoPike? I'd be very grateful if anyone would be kind enough to help me find such a configuration file - as my old xine one doesn't work in VDR. Best regards, GJ

Patch: dxr3plugin OSD don't turn pink
by Martin Cap 18 Apr '05

18 Apr '05

Hi ML, Hi dxr3plugin lovers, Attached to this posting is a patch which fixes the odd problem making the osd turn pink after returning from mplayer or after hardware-reset of the dxr3-card. I posted this fix in a german-vdr-forum a couple of months ago and it works for other users there, too. I haven't found the time to post it here (other users hadn't either:) )... so, here it is. Now what this patch does is it changes some behavior of cDxr3PaletteManager. It seems, that after returning from pmExtern_THIS_SHOULD_BE_AVOIDED, palette-data in cDxr3PaletteManager is somehow broken after resuscitation (whatever happens there, the code is a total mess). I avoid this by *not* converting the whole data allover again in cDxr3PaletteManager::GetPalette() through Tools::Rgb2YCrCb() and copy it to m_pal (only when palette-data has changed, indicated by member m_changed, should speed up the whole process a bit additionally). This patch may be applied to current CVS (HEAD or MAIN, also vdr-dxr3-0-2). Give it a shot !

cvs dxr3 and ac3?
by Prakash Punnoor 18 Apr '05

18 Apr '05

Just a quick q: Does current cvs dxr3 plugin support ac3 output with vdr-1.3.23? In doesn't work in my case. :-( dxr 0.2.2 and vdr 1.3.6 works with ac3. -- Prakash Punnoor

I've been working on enigma to adapt it to the limited capabilities of the dxr3 (it's not possible to display the channel logo, so I used all the area for the channel info). The problem is I didn't remember this thread so I made by myself the fixes already made by C.Y.M.. Probably because the latest version I could find at vdrskins.org is 0.1 :-( BTW, I don't know if it's a text2skin problem or an Enigma one solved in 0.2, but I get no icons[*] for the plugins in the main menu if they're not in the position 1..9 (e.g, if there isn't a number the vdr-logo is shown instead of the plugin logo, if I change the ordering to put a plugin in position 1..9 I can see its logo). [*]note that for the icons to show with a dxr3 you'll have to reduce the colors to 6 *and* wait for a patch to the dxr3 plugin I'm working on -- a patch that's not included in the patch Ville is (hopefully) going to commit to cvs today or tomorrow.
