>h.264< ?

Hi, yesterday I read a newsline called "h.264" in a magazine. I`ve wondered me because they said, it makes mpeg1+mpeg2 files only a half/quarter of the size it would produce today. But only the hardware today is to slow. Anybody heard something else about? Or can somebody correct me if I`m wrong. [Update] For all who want to test the interesting new codec and maybe the future of MPEG goto Rarewares under the mpeg section The source can be found at The project is still in very early development. So all who don`t want to test the codec may waste time because even with the fastest settings it still takes some minutes to encode a single frame. Also decoding is very buggy. But the result is amazing. All people should hope that this project gets continued because the potential is huge. good settings for the encoder.cfg: (from Tommy Carrot, Selur) -reference frames=1 -searchrange=8 (instead of 16) -RDOptimization=0 -AdaptiveBlockTransforms = 0 (may result in crash, I have to set it to 2) -NumberBFrames = 0 (disable) decoder.cfg: -move the file to C:\ or maybe the codec won`t find it -set: 0 ........NAL mode If your are still not able to decode the avi, use to convert the yuv file to avi. Use a low res to speed up the encoding! @developers Please continue the good work! It`s worth doing so!

If you searching for "H.26L", you will find more matches. It's the old/development name of H.264.

Yes, but at least the author seems to be alive.

ok, I tried to download the source and compile it, but I`m not so familar with sourceforge`s system. is there a tool to download the source easily? (I tried WINCVS, but I had many problems with this tool) would be cool if someone answers...

@IBJr sorry i forgot to mention the old name H26L @Shootist there you can find the newest unofficial Reference Code by one of the VCEG Memberst he is the Software Maintainer and as you can see long time no update has been done on the Reference Code it looks like their almost finish and the new Spec is going to be released soon only speculations but the evidence speaks for itsself :) Mpeg-4 V10 AVC lays in Santas christmas bag ;)

Be warned: The reference software is VERY slow. It ain't good for anything else than short (~100 frames long) tests. But after the h.264 is standardized, i guess we shall see several project based upon it. Maybe Xvid2 too? :D

h.264 is going to be adopted to the mpeg4 standard as "Advanced Video Coding" AVC profile. So no need for xvid to split up - or did we call it xvid1 vs xvid0 when we started implementing Advance Simple Profile (vs. Simple Profile)? We'll modify the GUI so you can choose the profile you want to use for encoding which enables/disables xvid's vfw controls accordingly. But let's wait for the integration/presentation of h.264 into mpeg4 first - and let's make ASP stable. Regards Koepi
