MPEG-4 AVC/H.264 video codecs list

Well, how % possible it is that Sony placed "mainconcept" id accidentally on it's AVC!?! Let's be reasonable.

i would only say thats for sure if elecards devs confirm that its really that way

Why would devs have any idea about what the sales department is doing?

you are speculating, not more

i can say that a dev told me that elecard wrote their avc and mp4 stuff from scratch and i believe a elecard dev more than i believe in speculation, period

this list should be about facts and not speculation

I'm not speculating, just putting 2 and 2 together.

Now I could say "writting from scratch" fits into my claim "or was rewritten", and I could say "you will not have 4 AVCs out of this 4 companies but ONE"... But I give up because you tend to miss the point in favor of writing another fast reply.

[bond]

you dont seem to get it

eg if elecards decoder would be a continued moonlight decoder, than why is it so clearly damn slower than moonlight?

you are speculating and wrong...

As many of you allready realized moonlights H.264 codec isn't in development any more and should be listed as (abonded) and sure the're encoders/decoders on that list that are based on licenseing the H.264 Sdks from Mainconcept/Elecard out to ISVs that don't wan't to invest the research to implement support in their Products for H.264, testing those again will be mostly a waste of time. For Sony that is bitter and could mean (i don't say it is so) that they don't belive in their own H.264 implementation and if you see the latest task they doing in the Blue-Ray Case moveing back to Mpeg-2 it seems as they don't want to invest much research anymore into H.264 so licensing others High Quality Researched SDKs is easier for them.

For Sony it's easy to forsee what their Strategy in cases of H.264 is Devices that have enough Space as Blue-Ray will use MPeg-2 and Devices that are in the Handheld criteria that run under low bandwith considerations as the PSP will use Mpeg-4 ASP/AVC and to me on a economical standpoint that is a logical stepp, Chips that will allow higher compression of Data will only bee seen on Devices that need them and Blue-Ray isnt such a device Product Costs could be minimized this way tremendously in every class, we mostly will see H.264 in STBs and for HD-DVD and as i said handheld low bandwith devices as Cellphones and Portable Media Stuff. But it would be non logic to use Higher Compression in a Device that has enough Bandwith and Space so it wouldn't need it and im sure Hollywood will see it the same way.

well moonlight is trying to sell their stuff, maybe someone will pick it up and continue developing it (their decoder is definitely very good)

well again, i till now didnt see any proove that sony uses elecard/mainconcept. yes they seem to use "mch264dec.dll 1.1.27.0 H.264 Video Decoder Wrapper Copyright© MainConcept" and "h264vout.dll 1.1.24.0 H264 Video Wrapper Copyright© MainConcept"

now this still doesnt proove they also use the elecard encoder/decoder

I don't agree with your considerations about AVC and Blue Ray disc (or any other large capability device like BD or HD-DVD).
Using AVC can implement very high quality compared to uncompressed source and lossless compression (but I doubt that they have implemented the lossless option in the BD specs, also if it uses HP@L4 and 4.1 if I'm correct).
They want to use MPEG-2 merely because:
1) they are very very stupid.
2) they want to make it backward compatible with the actual DVB broadcasting (allowing direct recording of DVB material on BD) and wi
th the actual DVD standard (and maybe because they aren't ready to use AVC yet).
At least I think so (or we'll use MPEG-2 for the next twenty years???).

Ok, lets stop the rumors - _currently_ Sony uses their own AVC encoder. The binaries in Sony Vegas you are refering to is very old Mainconcept AVC encoder/decoder (before joining of Mainconcept with Elecard) that was released 8-10 month ago. Those binaries aren't used inside Sony Vegas.

Thanks for info! I'l update list soon with removing of products to separate post (this will save place for info about codecs).

What doesn mean company closed? Seems like you want to place this in front of Moonlight, isn't it?
And please remove the comment - MainConcept uses latest MainConcept's encoder, not "Elecard Encoder H.264 from March 2005". Thanks.

well mainconcept uses the encoder developed by elecard, no?

Sorry! Bug in "List of fixes". MainConcept & Moonlight was swapped. Main list was correct.

Fixed!
