@ Neuron2, I am mostly a reader this is why I have just a few post due to my long time membership.

I do want to say that this is an impressive software, yes it is alpha but works excellent. DGMPGIndex is not just a tool is a masterpiece.

I see this DGAVCIndex becoming another masterpiece. Although, I don't place many comments I do use and wait in anticipation for every release of yours.

Thanks, for the great programs.

I've got the feeling that Alpha 5 is slower than Alpha 4, or are those feelings just figments of my imagination ?

Can't you time it for the same stream with both versions?

I can't think of any change that would have affected the speed.

Just started an x264 encode with 1.0.0 Alpha 5 and I saw this in the console

Code:
Compiler did not align stack variables. Libavcodec has been miscompiled
and may be very slow or crash. This is not a bug in libavcodec,
but in the compiler. Do not report crashes to FFmpeg developers.
It's encoding and i'll leave it on, hope nothing's wrong. Thanks for this great prog!

Oops, forgot to zap that message.

It's a big can of worms. Search for it on Google for details.

Anyway, it'll disappear when I get the native Windows compilation done for the DLLs.

I'm curious about your application. You're transcoding H264 to H264. What is the origin of the source material and why are you transcoding it?

In general 3 things:
1: H.264 HDDVD
2: H.264 BLURAY
3: H.264 (MBAFF/PAFF) Satellite streams

Mostly transcoded to fit on dvd5 or dvd9, for your burning pleassures.

Welll; Got the results in .... the difference between Alpha-3 and newer versions was indeed remarkable. The difference between Alpha-4 and 5 was negible.

Test was done on my "used to be über machine", dual Xeon 3.06 / 2 Gb registered, HT swithed on.

Test file used was 151604 frames@23.976fps, approx. 1hrs, 45mins, 23secs.

Code:
avis [info]: 1920x800 @ 23.98 fps (151604 frames)
x264 [info]: slice I:1955  Avg QP:17.72  size:156220a 0:00:00
x264 [info]: slice P:89115 Avg QP:19.57  size: 67233
x264 [info]: slice B:60534 Avg QP:20.51  size: 28493
x264 [info]: mb I  I16..4:  1.8% 97.4%  0.8%
x264 [info]: mb P  I16..4:  0.0%  7.5%  0.1%  P16..4: 46.5% 24.9% 13.6%  0.2%  0.1%

x264 [info]: ref B  53.3% 30.2%  6.9%  6.4%  3.3%
x264 [info]: kb/s:10149.0
Indexed this same file 2 times per alpha-version, and took average on the time needed. Rebooted in between runs, and disconnected network/killed firewalls and virus-scanners.

Indexing on:
- Alpha-3 took approx. 300 seconds
- Alpha-4 took approx.1530 seconds
- Alpha-5 took approx 1530 seconds.

Also observed that the programm used 1 tread, out of max. of 4 possible threads.

My conclusions, based on the huge difference between A3 and A4 and the reported errors in previous posts, is that it looks like something went wrong when AVformat-51.dll was eliminated/build into the package. But thats only a guess; It could also be that integrating/switching to the new GUI is somehow involved.

Hope this helps Neuron2.

But anyway, taking long or not, it's s
till looking out to be a very good tool

I think inline asm code of ffmpeg is skipped during the compilation with visual c++

The indexing does not use libavcodec, it uses code from the reference decoder only. I will investigate. My tests show just under a factor of two, though.

Anyway, libavcodec is still being compiled with mingw/msys.

Oops forgot to note that I observed that 1 thread was used bij de programm, out of max 4 possible threads. But i knew that it isnt multi-threaded yet. Edited my post to include this info, so it's easier to read back.

I finally managed to get DGAVCDec to work with the libavcodec from ffdshow_tryouts. That means I am now able to trace and debug the decoder DLL seamlessly with my application. Another step towards PAFF.

Performance seems no worse than with the mingw/msys build.

The errors that i mentioned earlier didn't have any influance on the encode. Everythin went fine.

Something new has come up, when I load a h.264 file thats in a directory with a long name (48chars) DGAVCIndex crashes.

You said DGAVCIndex crashes. When does it crash? When you open the file (then give me the path and file name for the input file)? When you Save Project?

Or did you mean the crash occurs when you load the AVS into something?

Please be precise. There's no point to give me the script if DGAVCIndex is crashing! You're just confusing me.

Oh yeah that's right. Sowwy for the mixup, stupid me. DGAVCIndex is indeed crashing when opening C:\MPG\DVDSource\Romeo.and.Juliet.1996.DVD5.720p.HDTV.x264.PROPER\romeo.and.juliet.1080p.h264.dd51_video1.h264

Doesn't crash when opening C:\MPG\DVDSource\Romeo\romeo.and.juliet.1080p.h264.dd51_video1.h264 or My Documents\romeo.and.juliet.1080p.h264.dd51_video1.h264
