Thanks, I missed the DS filters.

It's only me or everything encoded with this encoder looks like crap?

These patent wars are dissapointing. The people on this forum most certainly can design a codec that outperforms even the hype of the commercial products. Apple, Sorenson, Adobe, etc. win in marketing and legal muscle. x264 wins in actually having a great product.

You must explicitly run the command prompt as administrator when using regsvr32 on Vista/7.

I see the comments on how it compares to X264 but I was wondering on how it compares to XviD. I am not really an expert in video but to me XviD@Q=3 is approx equal the quality of X264@Q=22 (single pass of course); but the XviD video filesize is appox 25-35% larger.

So if VP8 video quality equals X264@Q=22 for 10-20% larger filesize I could live with that.

I guess all the decoder boxes out there (Popcornhour, WD TV Live, Seagate Theater, etc) will never play VP8; right?

There's a "libvpx 0.9.0 visual studio build" here with Windows binaries.
Example encoding parameters are on their website.

I think VP8 is not all too bad on medium and high bitrates. The crew_4cif test sample on low bitrates shows some problems after the flashes, quality drops really down, but that should be fixable with some encoder improvements I hope.

Done,thx!But it seems that MPC can't call VP8 decoder in Win7?WMP is ok though.

A thread title starting with 'WebM' might be better.

Ohh thanks! Somehow I overlooked it...

Works for me on Win7 32bit

The VP8 decoder doesn't work with MPC-hc x64 version on Win7,but both MPC-hc x86 version and WMP are ok.

The filter is 32-bit so it will obviously not work in MPC x64. It will also not work in Media Center on Vista/7 x64.

Adding WebM to StaxRip would even be better.

I just need to add a new encoder, a few tweaks, some updated applications and some new profiles but still it will take time.

Before adding WebM support I have to finish revising the complete UI adding high DPI support.

My initial (non-)impressions about VP8 :

at the moment, NOT supported outside of the WebM «sub-container» Until Google, or someone else, releases a real CLI encoder/muxer, a stable DirectShow decoder, and (seriously!) a VfW .DLL, I will keep having very-little curiosity about it.

P.S.: I did give a try to "ivfenc.exe". What the heck, it's infinitely slower than the VC-1 DMO encoder.
Completely unusable for "obsolete" rigs like mine.

Make no mistake though ... he linked it because it gives his earlier patent arguments a sheen of respectability from an independent source.

Shame that that part of it was entirely build on assumptions (not a patent number to be spotted).

Unfortunately the audio does not decode properly with CoreVorbis or ffdshow.
Same here whatever audio decoder is used, I think the problem comes from the "official" DirectShow filters.

However this build of VLC can play it fine.

Ah finally something that works, thanks for this link.

I couldn't get the DirectShow encoder to work (crashed with assertion failed) and the command line tools are creating raw streams only that nothing can mux.
What a pity, what a bad start for a new standard (?).

Sorry but this Kid stuff doesn't really is the nature of Doom9 (MOD ?)
especially not in the importance of the situation we are facing, something like this doesn't really helps
