Better Deinterlacing

[ripa]

I use VLC for watching IPTV (multicast MPEG2), which means practically all the material is interlaced. The only full frame rate deinterlacer VLC currently offers is the bobbing deinterlacer, meaning the vertical resolution is halved. The "X" deinterlacer seems to be the only adaptive one, however, it is too aggressive (stationary parts get deinterlaced as if they were moving very easily) and it only produces half the possible frame rate.

MPlayer currently has an awesome deinterlacer called yadif. I've tried it on material recorded with VLC (from IPTV) and I've yet to see any deinterlacing artifacts. It works in real-time (on standard definition MPEG-2 decoded by a 2400+ AMD Athlon CPU) and seems to work great on pure interlaced as well as hybrid or film-based material.

Could it be ported to VLC?

Sounds like a good idea. I'll give it a try. (Feel free to ask for updates if i don't reply to this thread in like 1 week)

How's it going? I'm looking forward to trying it out.

Please please port it! VLC desperately needs better deinterlacing.

My experience with mpeg2 multicast is that you have to check the "interlaced encoding" checkbox at the "ffmpeg" settings in order to get a decent picture out of it. This is, offcourse, assuming you also use VLC to stream it, not only to play the stream.

any updates

I would also be interested in Yadif porting to VLC, any development around this?

Might better to ask this in mailing list or in IRC. Most devs don't follow the forum.

The latest VLC (at least 1.0.5) has Yadif deinterlacing (use the 2x option for fluid video). Works great!
