#569 Serious design flaws

[Anthony Tsaukpaetra]

Based on how few tickets are handled, I don't expect anything to come from this, but here I go.

First, DVDStyler uses WAY too much memory. It seems to keep raw frames from each loaded video, doubly so if durations are set for items in the menus. This is a serious flaw that could very easily be taken care of through the use of temp files and partial renders. A full menu suite and titlesets should take no more than a few hundred MB in memory at MOST. This problem leads into many of the others.

Second, DVD Styler buffers IN MEMORY the output of most commands. It upsets me greatly when FFMPEG takes up 2 gigs of ram because the last parameter was a dash. This problem exacerbates crashes when using animated menues, as memory used while generating them does not seem to get released and it throws off generation, especially if cancelled and restarted.

Third, animated buttons fail to work properly due to the first and second issues, and this issue gets worse the more animated buttons there are. I'm not sure why a well-known program such as AviSynth isn't being used for this purpose.

This is a wonderful program for the features it has, but it just seems to need a bit more polish.

Do you code? Can you volunteer to do some rewrites?

I think this was supposed to go to anthony. I do code, but not in C++. I
mentioned the help file.

I can code, however I don't have any working development machines at the moment.

Fixed in DVDStyler v2.9 rc 1.
Please test

It does seem to be doing much better, though I don't have the original project files where this issue occurred to test with anymore.
It still seems to chomp away at memory too happily, but at least it doesn't leak anymore. An interesting thing is happening with ffmpeg all of the sudden with buffer underflows, but I will probably put that in another bug report later. http://pastebin.com/Bz3cBdXD
