Hi @carlos,
I also encountered the “too many open files” bug with MovieStim3 lately.
After digging through the source, I used the following hack to ensure that my movie stimuli were deleted from memory after use.
After playing a movie, I call the following on my MovieStim3 object, called “encode” in my case:
del encode._mov.reader
del encode._mov
encode._unload()
Maybe this also helps in your situation?
All the best,
Frank.
