so if im getting this right, Jrch2k8 has made or ported someones existing IDCT sse2, and he likes and understands x86 assembly ?
i also seem to get the impression (reading some post or other from him here) that he also knows TGSI assembly and will be writing that too ?
so, your at a very early stage and are basicly wanting to use any and all the other missing parts MC,CABAC , CAVLC etc for your Decoder from elsewhere or new wrapper code etc where needed Yes?
hmmm, Yet it appears Jrch2k8, you and whoever have not actually appeared and asked questions where your most likely to get in-depth help, feedback and actual working code to look at and learn from.
that being the codebase and IRC dev channels for x264 and FFmpeg or Doom10
Dark Shikari and team are VERY helpful (but will call you on stupid if you say you actually get something explained then turns out you dont lol )and encourages all new devs to ask video Encode/Decode and related code questions as soon as possible, preferably before they make to many 101's or waste time working out problems that dont exist, they dont care who you are, as high ranking intel guy found out until he got on IRC and finally understood their working practice .
for instance see http://doom10.org/index.php?topic=658.0
for the x264 openCL code some non x264 dev's patched http://www.gpucomputing.net/?q=node/1143
http://li5.ziti.uni-heidelberg.de/x264gpu/ but no one seems to know if it even runs, never mind might give you hints and in your DEcode project but worth a look perhaps, but apparently they never did talk to DS Etc to get it submitted, submitting easy
theres also http://x264dev.multimedia.cx/archives/157 search on x264 IDCT or whatever video related term you like and the chances are Dark Shikari or a related x264 dev has made an indepth block about it.
for instance the x264 dev's helped make the FFmpeg VP8 Decoded the worlds fastest LOL.http://x264dev.multimedia.cx/
adjusting and expanding the x264 code framework to help, and some of the x264 dev's are right now working on x262 the Mpeg2 Encoder using this same x264 framework remember also, ffmpeg being their preferred input/decode code base and they hack that too, DS etc having rights there to post patches and new code etc with write access to the repo.
all told you and indeed any dev's wanting to know Detailed inner working of video are well advised to go over to freenode.net/ and Actually talk to Dark Shikari and the other x264/FFmpeg dev's in #x264dev and #ffmpeg-devel as that is where actual development happens.
you can even use any part of their code and get algorithm advice and details...
