There's a reason DigitAl said he didn't want comparisons... you can tell where this thread is going to head if you keep using them.

The DivX encoder isn't competitive yet--that's why its an alpha

I just sent my sample to a fried and he liked the "DivX" version more, because it looks softer

Liar!

WhisX.exe generates a WhisX.bat and executes it. Open the generated WhisX.bat, quote the content.

Update:

WhisX now quotes filenames (hopefully) as necessary; and a few cosmetics (command line copyable; pyramide checkbox with optical feedback to B-reference checkbox).

No version tracking. Just download (again).

Update:

Settings management via INI files; an INI file with the same name as the application (e.g. "WhisX.ini") in the application folder is used as default settings during startup.

Why you don't run the encoder directly and redirect the console output to the GUI application? Is that planned?

I create the batch file on purpose: On one hand, both CLI and GUI are expected to be buggy; on the other, it is not yet worth the efforts, the next encoder may have a remarkably different set of options; and finally, you don't really need a GUI, do you?

Also it is not easy anymore to find out how to redirect console outputs to Delphi... most Delphi websites are already dead...

I can send you my code, in case you are interested

Basically I ported the code from this article to Delphi and added a few things I needed for LameXP:

LigH, here is a simple Demo application I just hacked together:
http://www.mediafire.com/?mamwiyubawt

(Sources included, the EXE was compiled with Delphi 7.0 Professional)


EDIT: Re-uploaded an improved version. Link has been updated!

EDIT2: Re-uploaded an improved version - again. Link has been updated!

Great.

Not sure if I will use it already for DivX264 CLI alpha 1, but maybe some day...

It already works with my simplistic Demo application and this commandline:
cmd.exe /c "C:\Program Files (x86)\DivX\DivX H.264 Codec CLI\bin\WhisX.bat"

(But the log filter would need some adjustment for divx264.exe -- done, see post above)


@ DivX developers:

It seems the DivX CLI encoder is missing to call fflush() after writing the progress line to STDOUT/STDERR.
This will cause a nasty delay when redirecting the console output...

x264 does do it the following way:
Code:
            if( i_frame_total )
            {
                int eta = i_elapsed * (i_frame_total - i_frame) / ((int64_t)i_frame * 1000000);
                i_progress = i_frame * 1000 / i_frame_total;
                fprintf( stderr, "encoded frames: %d/%d (%.1f%%), %.2f fps, eta %d:%02d:%02d  \r",
                         i_frame, i_frame_total, (float)i_progress / 10, fps,
                         eta/3600, (eta/60)%60, eta%60 );
            }
            else
                fprintf( stderr, "encoded frames: %d, %.2f fps   \r", i_frame, fps );
            fflush( stderr ); // needed in windows

LoRd_MuldeR & LigH: Wow, you guys are on fire today!

LoRd_MuldeR: I'll log the fflush() issue. Side: I already have an issue logged where some of the -help is written to stderr instead of stdout.

LigH: I have a suggestion for your app!

You could support a wider range of inputs by doing this:
  • If the input is AVI or AVS, write an intermediary AVS script that loads the input file via AVISource
  • If the input is another type, write an intermediary AVS script that loads the input via DirectShowSource
  • You could use Don's command-line guide for DGMPGDec to handle MPEG formats if it's available on the system.

After writing these intermediary files you can open them with the windows AVIFile APIs and check the rate/scale of the video stream to make sure it's valid and if not automatically apply something like ConvertFPS with the nearest allowed rate/scale. You could also check the width and height and apply AddBorders and/or a resize if necessary, then finally pass this AVS file to the encoder. If you want to get really fancy you could add ConvertToYV12 to the AVS script and get the picture in a known format through the AVIFile interfaces, then apply a routine to determine a crop window to remove borders, checking various frames throughout the file. I think you can also get PCM samples easily this way so you could write a WAV file then pass it through an audio encoder and hook up mkvmerge to bring everything together.

buzzqw: I sent you an e-mail, I'd love to see AutoMKV support this!

LoRd_MuldeR & Dark Shikari: Thanks for the comparison vid, and for keeping the conversation on track! I haven't had time to thoroughly investigate it yet but x264's new psy does seem impressive I did notice that the clip is rather low motion and x264's settings were quite extreme - e.g. 16 refs, 15 consecutive b's, ~20s IDR interval, so I'm wondering if this is somewhat special case. Anyway, I'll look into it further I think we also have that clip so I can recreate it with more comparable settings.

I'm disappointed that there is no constant quality mode, which is a necessity for my purposes. Did I just miss a commandline option or something?

DeathTheSheep:

Constant quality is not available because it doesn't allow management of rate spikes. Keep in mind that the encoder is designed to create CE-friendly streams. 1-Pass target-quality on the other hand is one of the most requested features at present.

Isn't that the entire point of "constant quality" mode? Use as many bitrate as needed and don't care about the final size or bitrate spikes?

Obviously 1-Pass makes it hard to implement VBV restrictions, but it should be possible to run a simple 1-Pass CQ encode without any VBV restrictions at least...

Yes, that is the entire point of it and the entire problem! The encoder, at least in this early version, is designed to implement the draft profile. Modes that would typically be part of unconstrained operation aren't available because currently this isn't the intended purpose of the release.

However, we are taking feedback about all requested future options. How important to you is constant quality mode and what are the situation under which you'd want to use it?

Latest StaxRip beta has DivX H.264 support. Compressibility check is missing because there is no constant quality mode. I use crf 22 so not having a constant quality mode is a show stopper for me. Since the encoder is privat + alpha it will only show up if the encoder is installed. GUI looks as follows:



For those who wonder why I often use the TreeView instead of real controls, reasons are: Every option requires a single line code only so it helps to fight bloat, it's quick and easy to code, easy to maintain, easy to change, easy to extend and automatically clean and polished.
