#7245 closed feature request
Gzip cutscene-files/LEC-style talkies
|Reported by:||SF/thanius||Owned by:||fingolfin|
You should implent gzip (or compression) support for cutscene-files as in The Dig and Full Throttle. As for the moment, the game takes a total of 421 MB with compressed audio and speech. It would be great if it were possible if we could reduce this size to about half, at least.
Another thing, one thing I've hated with the Simon talkies is that you can't display text and speech at the same time as in the LEC-talkies. This would be great, because the speech's got low volume and sometimes you can't hear what they say. This could be really annoying, specially when you've got stuck somewhere.

I think bzip2 is the best free data compressor. I dont like if somthing is compressed with bad compression factor (like gzip/zlib?) because you cant compress something twince.

It's not as simple as that.
First off, of course you can compress stuff twice, and if it was really badly compressed the first time, you will even save space (but that largely depends on the data and the algorithms used).
Secondly, gzip/zlib is certainly not bad! In many areas, bzip2 beats it, true, but it's not true that it is always better.
Furthermore, compression ration is not the only factor. Other factors include license of the lib, portability, speed of decryption (bzip2 is much slower than gzip), memory usage (bzip2 needs memory buffers, and the better the compression ratio you want, the higher the buffer and the more time used).
In any case, don't get me wrong, neither am I suggestion we will use zlib nor bzip2. We might not do this *at all* in fact. Or if we do it, might use a 3rd library or even our own compression code.

I don't think combined subtitles and voices will be possible in the Simon the Sorercer games for several reasons: Simon the Sorcerer 1 talkie/win don't include full text for the game. The subtitles in Simon the Sorcerer 2 don't match the voices exactly. It seems impossible to get the timing correct in all cases, with subtitles showing up too late and disappearing too quickly. Since many of the voice files contain multiple sentances.

Closing this two-part FR (please in the future file on request per suggestion :-).
Regarding the compression, this is covered by FR #663772, and the subtitle part is apparently not really possible (see comments).

This would require us to add in compression code. Either zlib (what you call gzip) or something else. Since ender expressed his dislike for zlib, that seems to be unlikely. Maybe we will use LZO for save game compressions, but we need permission from the author for that and we haven't yet heard from him.
Assigning this to ender so that he may comment.
