[MEncoder-users] Xvid bff/tff field order issue

[Jarek Czekalski]

I posted a patch that inserts tff flag into xvid. I posted even a patch 
showing tff/bff flag while playing videos. The crew was not interested 
in fixing this entry. Generally they don't care about interlacing videos.

Although I was not satisfied with ignoring my work, I finally decided to 
switch to non-interlaced archives. They convinced me to do so and now I 
have better quality movies than before. Still I have my mplayer 
corrected to be able to encode tff xvid.

Now I noticed gmane search engine doesn't work well and even it ignores 
my posts. This problem is reported in another mail.

You can see my 4 posts regarding xvid interlacing on archive of Sep 2010.

> H_.mpg 		(7.14MB) is the original tff PAL input file. It plays fine on my computer as well as on my TV.
> H_fd0.avi 	(2.99MB) is bff encoded with mencoder -ovc xvid -xvidencopts profile=asp5:.... without -vf phase=t
> H_new.avi 	(2.99MB) is tff encoded with the patched mencoder.
