This is now available (https://helixcommunity.org/forum/forum.php?forum_id=666)...

Our Codec and Helix development teams are proud to announce the availability of MPEG-4 AVC/H.264 decoder source code, completing the list of the best of the breed existing video codecs such as RealVideo 9/10, AVC/H.264 and the original MPEG-4 video. Beyond current video codecs, new and exciting work on our Next Generation Video (NGV) technology is already started.

Our new AVC/H.264 decoder is a cross-platform, portable, C/C++ implementation that implements the Baseline and the Main profiles. The code is made available for R&D at no cost (for commercial use contact MPEG-LA or Via Licensing) to all current licensees of the current Real Format Source Code Porting and Optimization License - Decoder (V3.0) and by amendment to older licenses.

wow! i guess this gives the hint that real might go the avc way in the future too (ngv?)

baseline and main profiles... that's not "smart" considering HD-DVDs are encoded in high profile.
probably it is the "basement" from where they will start building their closed source decoder and encoder...
if Real is really intentioned to build and all-in-1 mpeg 4 solution they will have a great product...

OOOH!!!!!It is a reality.

If Real was working hard behind the scenes this whole time, there is not only a chance, but a tangible possiblity. Of course, this is all cheifly speculation...DeathTheSheep

[QUOTE]Real is definitly working on something.
What is what's left to discover...Sirber

I wonder what would say DeathTheSheep? :p
What is the reaction of Sirber? ;)
Then what thinks Karl? :)

Bye.

I envision a day when hard drives will be huge and all CPU's will be powerfull and all video will be lossless. This would be NGV to me.

copy pase of coreavc source code? just a guess...

Guys, if you want to speak about NGV open a new thread please. :sly:

Only a Decoder..
Maybe they will open-source the decoder and sell a pay encoder..

Well done move, the On2 should do this too...

I wonder if there is a download link of binary.
I can't deal with source that is made by others so far.

Appears to be a license/form that you fill out. Then they send you the source.

I do not think we will post the actual DLLs, but we will check .lib files into the build system (probably for Win32, Linux, and OSX at first), such that the DLLs can be built by anyone with a Helix username/account.

Regarding access to the actual source code:
"The code is made available for R&D at no cost (for commercial use contact MPEG-LA or Via Licensing) to all current licensees of the current Real Format Source Code Porting and Optimization License - Decoder (V3.0) and by amendment to older licenses."

heya karl, judging from this (https://helixcommunity.org/viewcvs/cgi/viewcvs.cgi/datatype/h264/codec/decoder/?sortby=date) i suppose you are the author of the decoder? ^^

btw can you tell us whether this decoder will be/is part of "NGV"? ;)

bond: No, but I did the check-in and am responsible for any bug fixes and enhancements. The H.264 decoder has nothing to do with NGV.

Also, I have checked in binary distribution libs for Win32 VC7, such that now anyone with a Helix account, VC7, and the Helix build system setup, can build Win32 DLLs, without signing any license agreement. I will also be checking in for Linux, OS X, and other platforms, when our build farm is back up and running.

thx for the info :)

i hope someone writes a wrapper for the decoder for dshow or mplayer so i can benchmark it against the other decoders ;)
