Even with the beta there's still the "bug" with subtitles appearing 370ms or so too soon, as if the video is delayed. Same as previous versions.

So the new optimizations give ~10% better performance.
how much w/ the DivX decoder?

and that'd be interesting to measure the electricity consumption w/ a wattmeter...so we'd see if CUDA really has an edge over software decoding.

Is Graphstudio ok to measure performance? View -> Decoder Performance

With a 1080p clip at L5.1 on a Core 2 Duo E8400:
DiAVC beta: 81.3 FPS
DiAVC alpha: 72.6 FPS
CoreAVC 2: 63.0 FPS

Athlon 64 3500+:
DiAVC beta: crashes!
DiAVC alpha: 24.6 FPS
CoreAVC 2: 22.3 FPS

But on the Athlon 64 the actual use shows a very slightly lower CPU usage fore CoreAVC and it seems to behave better overall, so I don't know.

I have a very strange result:
Code:
coreavc 2.0
User: 2s, kernel: 0s, total: 2s, real: 3s, fps: 577.1, dfps: 415.0
User: 2s, kernel: 0s, total: 2s, real: 3s, fps: 563.8, dfps: 413.3

diavc
User: 2s, kernel: 0s, total: 2s, real: 4s, fps: 533.0, dfps: 356.0
User: 2s, kernel: 0s, total: 2s, real: 4s, fps: 573.7, dfps: 358.6

ffmpeg-mt
User: 24s, kernel: 0s, total: 24s, real: 24s, fps: 62.8, dfps: 62.5
User: 24s, kernel: 0s, total: 24s, real: 24s, fps: 63.1, dfps: 62.7

divx
User: 3s, kernel: 0s, total: 3s, real: 4s, fps: 482.9, dfps: 343.4
User: 3s, kernel: 0s, total: 3s, real: 4s, fps: 462.3, dfps: 344.6
Look at the ffmpeg-mt section.
ffdshow is the svn version from xvidvideo.ru. H264 decoder is ffmpeg-mt. Why the performace is so weak?

Edit:
system is hp 380G5, 2003 ent 32bit.

Maybe multithreading isn't being activated?

Is it an interlaced sample? ffmpeg-mt won't work on PAFF H.264.

DiAVC still seems to have a lot of problem with lower level (L1.1 Baseline/Main) AVCs. Such videos in FLV give green bars/corrupted videos. But after I extracted the streams and remuxed them in MKV it was fine, however, the extraced elementary H.264 stream run through Elecard Demuxer freezes on DiAVC. DivX doesn't have such issues.

Thanks. FFDshow's default threads is set to 1.

When set it to 8, the result is:
Code:
User: 2s, kernel: 0s, total: 2s, real: 4s, fps: 518.8, dfps: 332.9
User: 2s, kernel: 0s, total: 3s, real: 4s, fps: 508.0, dfps: 332.9
FFDshow prevents me to set thread to 0.

The crashing on athlon64 is perhaps due to the wrong use for SSSE3.

No AMD CPUs support SSSE3. Athlon64 3500+ supports upto SSE3. If some function in DiAVC relies strictly on SSSE3 code with no fallback, it'll fail on AMD CPUs.

A new beta version is available:
changes:
Fix the bug related to low-resolution videoes
correct code for judge SSSE3
Fix a bug on parsing prefix-length sps

The beta in your link (I suppose it's the lastest) is crashing here with a Pentium M and WinXP.

Looks that there is a bug related to the single-thread. I will fix it as soon as possible.

Re-download it now, I added a protection to prevent the pentiumM from using SSSE3.

@schweinsz: Wouldn't the correct way to handle this be to check the CPUFLAGS for the SSSE3 flag and only enable the code if it is present?

Previously I do this at the first release of the DiAVC beta, but two guys reports error, so I changed the code. I am not sure if the old cpu set that bit correctly.

I added a protection as follows:
__cpuid(nBuff, 0);
nHighestFeature = (u32)nBuff[0];
......
__cpuid(CPUInfo, 1);
nLogicalProcessors = ((CPUInfo[1] >> 16) & 0xff);
isSSSE3 = (CPUInfo[2]&0x200);
if(nProcessorType==AMD_CPU || nHighestFeature<=6) isSSSE3 = 0;

Redone tests. With a 1080p clip at L5.1 on a Core 2 Duo E8400.

DiAVC beta:
User: 2s, kernel: 0s, total: 2s, real: 18s, fps: 637.4, dfps: 79.7
User: 2s, kernel: 0s, total: 2s, real: 18s, fps: 604.0, dfps: 80.2
User: 2s, kernel: 0s, total: 2s, real: 18s, fps: 655.4, dfps: 79.7

CoreAVC2
User: 1s, kernel: 0s, total: 1s, real: 22s, fps: 770.1, dfps: 63.1
User: 1s, kernel: 0s, total: 1s, real: 23s, fps: 733.5, dfps: 62.7
User: 2s, kernel: 0s, total: 2s, real: 22s, fps: 655.4, dfps: 63.1

Still crashes on Athlon 64. And still problem with subtitles appearing too soon.

A new version is uploaded.
The implementation of the single-thread decoding for old cpu is modified.

It still crashes here. It's curious though, MPC loads the file, starts playing it and the crash report appears instantaneously. However MPC shows "Playing" and the time counter increases normally until you accept the crash popup. Black screen in the whole process.
