Deblock

Fizick · 23rd April 2006, 08:58

Some info about DeBlock function.
It was developed by Manao, and was present in old MVTools (up to v 1.1).
And the same function is in DGdecode plugin.
Recently I remove it from MVtools to separate plugin dll.
(with small additions - large limits, and YUY2 support).

I wonder, why in Dgdecode it has parameters "mmx", "sse"?
Really there are no any assembler code in its source.

Those are just vestigial remnants. Nothing to see. Move right along.

Sounds like good work on the filter! Thanks for sharing it. Shall I remove Manao's filter from my package or should I update it with your version?

From dgdecode manual:
Deblock() should not be used with MPEG-2 video sources.
Typically this means opening the video with AviSynth's AviSource() or DirectShowSource().

So, my suggestion is to remove it.

hi,

does anyone get problems by using deblock with mpeg2 sources?

I use Deblock and often prefer it over BlindPP. I never noticed a problem.

What is the reason why it is not supposed to be used?

It's not that it shouldn't be used or causes any problems. Rather, it's just that a deblocker with access to the MPEG2 syntax can do a theoretically better job.

Deblock() should not be used with MPEG-2 video sources.

And what about MPEG-1 ?
