#29 closed enhancement (invalid)

quicktime codecs on win32 loader will load all *.qtx in PATH(s)

the quicktime codecs (actually, this could be version dependent, but i think it happens with all ver qt5, qt6, qt6.3, qt6.5) will load all of the .qtx files in the windows PATH, which makes them load incredibly slowly, and also loads a good 5mb into memory for codecs that arent being used. verified by sascha. possible that timebomb (reza) was working on patching the codec.

workaround: rename/remove .qtx files until needed. this really only affects people with previous quicktime installations (most .qtx files arent included in quicktime codec pack).

note: not an mplayer bug, but a win32loader/quicktime bug.

I would not count this as bug. It is how quicktime works
it needs to load all plugins first to know what they are doing.
It does this via the windows file search function FindFirstFile/FindNextFile?.
Fixing it would mean adding a hack to the loader. For this hack to work
you need to know every plugin that is needed to decode a certain file.
Moreover this hack won't work for the windows port.
Doing a normal setup quicktimeplayer will workaround this by loading itself at
system start.
Your workaround still seems to be the best solution.
