Why is the MPEG4 Part 2 ASP encoded file always smaller than the H.264 encodec one(and which profile is used in the H.264 encodes)?

On the same clip, using the same filters (except for ffdshow which is 20051124). I got those figures on my P4 3 GHz with HT :

36.9 fps with nero
24.4 fps with ateme
22.7 fps with ffdshow

I did the measurements using Haali timeCodec application. The difference compared to CruNCher's results are due to multi-thread optimization of nero.

interesting, can you also test it without multithread?

and do you know what nero "multithreads" during decoding?

Well, since the clip in question has only one slice, it's the decoding process itself that is threaded. I would say that one thread decode the cabac and another make the MC / deblocking.

nero's codec is multithreaded? i'm trying it now to play back a clip i've made (1080p) and one core is maxed out on my 4400+ - i'm getting around 16fps on it. my 3800+ overclocked plays it fine (barely). same with ffdshow and libavcodec

indeed, nero limits their decoder to only work in nero showtime

shame, its not a bad player, but mpC is better.

hopefully libavcodec will be multithreaded some day may keep on using x264 from now on, i found it nicer on hdtv material than divx - although a lot slower

Just for the record this nero result is probably false (see http://forum.doom9.org/showthread.ph...588#post764588 ).

Unlikely. Such huge inter communication between threads would be more pain. But non reference b-frames can be decoded in a different thread.

@Bond: Perhaps CoreAVC should be added to this, bearing in mind it can be played on your machine now.

First legend : "MPEG4 AVC is slow" ... and at this time MPEG4 AVC is faster than all the other codec with better quality.

Second legend : "MPEG4 AVC is hard to play".

why not general comparison with other codec:

MPEG4 ASP + FFDShow dec PP0 (default) and PP4
MPEG4 ASP + XviD dec PP0 (Default) and PP4
MPEG4 ASP + DivX dec PP0 and PP4 (Default)
VP7 + VP7 dec PP0 and PP2 (default)
VC-1 + DMO dec PP0 and PP4 (default)

IMO MPEG4 AVC + CoreAVC dec is faster than MPEG4 ASP + PP4 dec or VC-1 + PP4 dec

You mean AVC with super-fast options, and ASP with slow options, like your other test? Sounds good.

... lol

1) My speed encoding test all possible encoding setting for all codec (fastest and slowest setting for all codec) and fast encoding setting for AVC are by far very better for quality and speed than MPEG4 ASP slow setting. "Slow setting" for MPEG4 ASP here are not extreme setting but usual setting for all XviD/DivX user like default setting for XviD (ME6, VHQ1, Chroma, Trelli)

2) Use CoreAVC dec is not an "super-fast options" but just decoder choice and PP4 is default setting for DivX dec for example. Doom9 in this test use PP4 for all MPEG4 ASP dec ...

3)

Quote:
MPEG4 ASP + FFDShow dec PP0 (default) and PP4
MPEG4 ASP + XviD dec PP0 (Default) and PP4
MPEG4 ASP + DivX dec PP0 and PP4 (Default)
VP7 + VP7 dec PP0 and PP2 (default)
VC-1 + DMO dec PP0 and PP4 (default)
MPEG4 ASP + FFDShow dec PP0 are slow options ?
VP7 + VP7 dec PP0 are slow options ?
VC-1 + DMO dec PP0 are slow options ?


For my Sempron MPEG4 AVC + CoreAVC (CABAC, High Profil, 16 ref and bref ... aka hardest setting for AVC decoding) is better for speed decoding than MPEG4 ASP (and without QPel or GMC ... aka not hardest option for ASP decoding) + PP4 ...

actually i think i indeed will add an asp sample to the comparison, encoded with slowest settings possible and decoded with the fastest asp decoder (which is ffdshow afaik)
