Deinterlace-plugins that do not destroy fps?
Hello! Is there any work going on to get better deinterlacing plugins to Mplayer? I'd like to be able to view interlaced material (DVD's, tv-card etc) at the full framerate (50/60fps).. Many of the good deinterlacing techniques are shown at the http://www.100fps.com. With deinterlacing methods like "Combination of Weave+Progressive Scan" you get the full fps and great picture quality.. Quote from 100fps.com: "How can you expect to have excellent results when you convert 50 fields per second (=50 snapshots per second) to 25 snapshots per second?" Good NTSC MPEG-2 clip available for testing is here: http://telija.net/~pk/FlickerBox.zip (originally from ftp.demodvd.org, but it seems to be down now..) When played at 30 fps (like mplayer does) the picture is not correct. Does support of these deinterlacing methods require big changes to mplayer? Please comment.. -- Pasi Kärkkäinen ^ . .

Hmm... Did you check -vop il and dint? Maybe it helps... Regards Jonas

Please comment..
Most of the stuff you've read on 100fps.com sounds like flamebait. Movies are 24fps to begin with (sped up to 25 fps for PAL, or telecined for NTSC), so there's no sense in trying to get 50/60 fps out of them. Methods like this could be good for made-for-television content, but you can have "excellent results" at 25/30 fps as well. For now, try using the various deinterlace filters and see what kinda results you can get. Use pp=md, lb, ci, or fd and see which one does best. Eventually mplayer should support the sort of frame rate doubling you're talking about, but it's difficult to do with the current architecture so don't expect it anytime soon. Rich

Yes, I realize that most movies made for film are shot using pure progressive 24 frames per second.. But, DVB (digital tv & satellite) is using a lot of interlaced 50/60fps material.. because of analog video-cameras. some DVD's are 50/60 fps too (like DemoDVD for example :) Also, stuff coming in from your analog tv-card (hauppauge & friends) is interlaced too.. and at 50/60 fps.
For now, try using the various deinterlace filters and see what kinda results you can get. Use pp=md, lb, ci, or fd and see which one does best. Eventually mplayer should support the sort of frame rate doubling you're talking about, but it's difficult to do with the current architecture so don't expect it anytime soon.
OK. What's the problem with current architecture ? -- Pasi ^ . . Linux / - \ Choice.of.the .Next.Generation.

Yes, but the source material in most cases (dare I call them "quality tv series/movies"? Pretty much everything except soaps) was 24fps film so what you get is two fields/frame that look the same (except for analog noise of course). Or perhaps you really like salatut elämät... :) Anyway, tvtime (tvtime.sf.net) for example does this sort of deinterlacing, pretty neat.

Hmm.. this looks nice! Hopefully someone ports it to mplayer so we can see the difference :) I personally don't have time to do the porting :( -- Pasi Kärkkäinen ^ . . Linux / - \ Choice.of.the .Next.Generation.
Hi,
For now, try using the various deinterlace filters and see what kinda results you can get. Use pp=md, lb, ci, or fd and see which one does best. Eventually mplayer should support the sort of frame rate doubling you're talking about, but it's difficult to do with the current architecture so don't expect it anytime soon.
OK. What's the problem with current architecture ?
while(!eof){ read_frame -> decode_frame -> filter_frame -> display_frame } anyway it's not hard to change/hack, but unless someone writes a high quality fast frame doubling filter it doesn't worth the work.

OK.. tvtime.sf.net seems to be such thing.. maybe dscaler.sf.net also does this? But, someone needs to port those :) -- Pasi Kärkkäinen ^ . . Linux / - \ Choice.of.the .Next.Generation.

In fact tvtime seems to be using mainly dscaler's filters :) -- Pasi Kärkkäinen ^ . . Linux / - \ Choice.of.the .Next.Generation.
