Does he know about the crash when the sequence of uncompressed pngs is used? Was it fixed in 1.6.3?

Some users may want to use uncompressed pngs via -moviecompression 0 -movievideo 0 to generate the highest quality video possible, then compress it themselves later on. As of version 1.6.2, Vdub crashes when this is selected.

Hi,

1.6.3 still crashes with uncompressed pngs. I've emailed him explaining the error, as well as sending a compressed/uncompressed sample.

Interestingly uncompressing crashtests MNG's to uncompressed pngs (which is an option in advmng.exe advancetool) and using those png's does not cause Vdub to crash).

Buddabing:
Okay, I have implemented the -movieaudio 2 change (custom) and uploaded a new binary.

To use -movieaudio 2, you need a file called acodec.dat. Put the SetConversion and SetCompression statements in there and have fun. I included the SetConversion because IIRC we were having a bit of trouble getting that to work so Silver hacked that parameter. This way he can experiment with changing the MP3 encoding.

I've also changed -movievideo 4 to use a file named vcodec.dat instead of just codec.dat.

After much wailing and gnashing of teeth, I've finally gotten the basic 0.91 MAME to compile. All I need to do is make sure all my changed code compiles.

Regards,
Buddabing

Incidentally, if anyone is wondering how to setup these dat files correctly, here's how:

Open Virtualdub manually, open any movie file or png/wav combo (doesn't matter what).

Then make sure you select "Full processing" mode for both audio and video in the menus, then select "Compression" for both. This will pop up a menu  where you can select which codec you want to use, and you will also be able to configure this codec in its own menus exactly how you want it.

Once ready, select "Save avi" from the File menu, and make sure you tick the box "Save this as a job to run later" (or similar). Instead of processing, Virtualdub will save a file called "Virtualdub.jobs" in its home folder. Open this with notepad or similar, and then copy out just the lines that Buddabing mentioned:

VirtualDub.video.SetCompression...
VirtualDub.video.SetCompData...

and paste these into a blank txt file and save it as "codec.dat" and place it in you BuddaMame directory. Exactly the same for the audio, except copy out the lines:

VirtualDub.audio.SetConversion...
VirtualDub.audio.SetCompression...

and save them in acodec.dat.


Hope that helps.

How's the update to .91 going?  Anything I can do to help?

Howard_Casto:
Just something I wanted to suggest....

I've noticed that even with compression the bitrate is suprisingly high.  You would be suprised how low you can knock down the bitrate and still have identical picture quality.  Even my near lossless captures I did for the old 3darcade videos had 1/3 the bitrate of the vids the mm makes with any of the compressors.  The reason I mention it is the bitrate acounts for a lot of the file size.  It may be possible to make these vids much smaller without any noticable difference.
