Hello People !
Well I want to know which companies or opensource developers showcase the fastest H.264/AVC Decoder @ various different Profiles i.e. Baseline, Main, Extended, High, High10, High 4:2:2, High 4:4:4.
Can someone provide the list of the fps at different resolutions of different profiles. :sly:
regards
Saad

You could search, you could precise a little bit what exactly you want ( pure-software or hardware-assisted decoders ? ), neither do you ask the processor used for the test ( some decoders are multithreaded ) and you should know that :
- a profile by itself doesn't tell the options used : a baseline video could be harder to decode than a main profile one
- the bitrate has a very large influence on the decoding speed ( up to 50% of the decoding time )
Now for an unprecise answer :
- CoreAVC is the fastest software decoder, but is payware
- FFDShow is the fastest free software decoder, and is 10 to 20% slower than CoreAVC on single core computer
- Hardware-assisted decoders get a speed on par or a little better than CoreAVC.
- I don't know any usable decoder that actually handle 10 bits/4:2:2/4:4:4. Since there aren't any usable encoders either, that's no big loss.

I just need the rough idea of the current fastest decoders.
well as for "Kurtnoise13" http://forum.doom9.org/showthread.php?t=99402
it doesnt contain CoreAVC. Wonder when it would be updated.

Manao are right :)
for me, the best decoder are Cyberlink h264/AVC with DXVA enable.
if you want i can download somes samples and doing some newer test.
