Re: [mythtv-users] Correcting overscan in MythVideo/mplayer
$ mplayer -version MPlayer 1.0pre7try2-3.2.3 (C) 2000-2005 MPlayer Team Interesting that you can scale to values I can't. Maybe it has something to do with the PVR350 Xdriver. Just for kicks I'm going to test the multiple of 8/16 theory out. I'll give xine a try -- I like the idea of being able to zoom via the remote control vs having to setup config files with mplayer. Thanks for the tuning tip, I'll give it a shot and see if quality improves.

I can play that file without problems using a size of 540 with Mplayer 1.0pre7. It also works with 541, 542 & 543. My own preference is to use xine for playback and map the zoom controls to the remote. That way I can still overscan, but tweak the size to ensure the subs are visible. btw, for fansubs (or any other progressive video) you may find that changing the yuv mode can improve video quality when scaling. You can do that with the following. ivtvctl -d /dev/video16 --set-yuv-mode=mode=1 The default mode is 0 (interlaced), so you'll probably want to reset it after playback. -- Ian ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I'm not sure I really understand resolutions very well. For example, scale=540:-2, along with other resolutions, completely garbled the image. Do you know how to determine "valid" resolutions without having to resort to trial and error? Yes, for mplayer they have to be divisible by 8, it looks like (I thought it was 16, but the fact that 520 works means it must be 8).

Yes, expand creates a black window the size you specify and drops your scaled video into at the coordinates you specify (or centers it if you don't specify).

Re: [mythtv-users] Correcting overscan in MythVideo/mplayer
The trouble seems to be with using the "-fs" option. No matter what I scale the output to, the PVR350 overscan still cuts off the subtitles. Is this just endemic with the PVR350 or am I doing something wrong here? The only thing that doesn't cut off the subtitles that I could get to work was the following: mplayer -quiet -geometry 32%:50% -display :0 \ -vf scale=520:-2 -zoom -vo xv /var/video/mythvideo/Lunar_Bleach_58.avi However, that leaves me with the window frame and a little clutter from fluxbox to look at while I watch my videos.

All the videos I watch happen to be subtitled anime, and the subtitles are being cutoff at the bottom of my screen. Any suggestions on settings for mplayer (or maybe it needs to be somewhere else) to scale the video down some? I use the following in ~/.mplayer/config for my 720p output : vf = scale=1184:-2,expand=1280:720:38::0 You can adjust it for your display size. the scale argument scales the video to 1184 wide and the -2 for vertical tells it to maintain the original aspect ratio. Then the expand argument creates a black window 1280 wide by 720 tall, and places the newly scaled video 38 pixels in from the left, while centering the vertical. Good luck!
