Thanks! I hoped there still was something that could be done about the 2GB Urban Runner data files but it's also good to know that theres no room left for savings. For Toonstruck, however, it should be different I think. Half of the data is in *.SMK video files, which should be compressible by conve...

Squeezing some MBs out of Toonstruck & Urban Runner data

I wondered, is it possible to save a few additional MBs on the data files for Toonstruck and Urban Runner? Both are pretty big, even when reducing the installation to just the data files (Toonstruck: 1GB, Urban Runner: 2GB). Here's my findings so far: Urban Runner: The compress_gob.exe tool (at leas...

I thought I've seen some minor jerking in "The 7th Guest" on my 2,6GHZ dual core, 1GB RAM, GeForce 6600GT desktop PC, but that might be just my imagination :-). Just to be sure, even with games like 7th Guest or (in a future release) 11th Guest, there won't be any problems on a PC this old...

Minimum system specs for SCUMMVM (all games playable)

I'm going to buy a used labtop (mainly for mobile work). I'm not that much of a 'gaming person' (at least when it comes to recent games), but theres one thing that has to be perfectly playable on it: SCUMMVM :-). I think that system specs are quite different for different games in SCUMMVM. I'm plann...

Yes, this might be the case. By resizing the image to half width/height, four pixels become one, and the average of the four is used for that one pixel. It becomes even worse as I used the Lanczos filter (I don't know what this actually does). This way new colors are introduced. Palette changes wors...

I just tried to reencode the DXA videos from Feeble Files. I extracted the PNGs, and modified them to keep only 1/4 of the information while maintaining the dimensions. I did so by resizing the PNGs from BincConv to 50% width/height first (using the lanczos filter), then sizing them back to their or...

Thanks for your help! As far as I understand (hopefully) now, a dxa file consists of a DXA header (starting with Byte sequence 'DEXA'), followed by a sequence of images (each starting with 'FRAM'). Each of these images is XORed against it's predecessor (this makes for better compression, as only the...

Sorry, I don't want to clutter the forum. It just seemed that this matter went a bit down in the other thread.

Also, the topic changed a bit from the initial topic of the other thread.

Standalone DXA Encoder

I want to do some experiments on the Feeble Files videos like leaving out frames or changing the dimensions. Is there any stand alone DXA encoder which is able to encode SCUMMVM compatible DXAs (from PNGs(?))? I already had a look at the encode_dxa (from SCUMMVM tools) source code and I think that i...

I've just checked, and you're right about that - ffmpeg only supports decoding a DXA file.

Is there any other (command line) tool which supports encoding of DXA besides encode_dxa from the SCUMMVM tools? I want to do some modifications to image quality/size.

Just a quick question:

Is the DXA format used in SCUMMVM different from the DXA format implemented in ffmpeg? I.e. could I also use ffmpeg to recode video files for SCUMMVM?

I once tried "Zak McKracken - Between Time and Space". I didn't get it to work, it crashed right after the beginning and no solution helped. This problem persists with many different configurations... Also, as far as I know, there's no english translation yet. It's a pity, as the game itse...

Another possibility would be resizing the images to half of their size, then resizing them back to their original size. The resulting images would be the right size, but would actually contain only a quarter of the information. As far as I know, DXA uses the same algorithm as ZIP to compress the ima...

I read a bit about how the DXA format works, and, in theory, it should be possible to resize the images from the SMK files to a smaller size and encode them to DXA then. F.e. if you half each dimension (width/height) of the images, the encoded DXAs should 1/4 in size. But how would this play out in ...

Of course, formerly commercial titles are allowed, too.
