Hi JB,
Just to clarify; a memory leak means that memory consumption keeps increasing because data that is no longer required to be in RAM is not being released.
Judging from your description, it sounds like the files you are loading in Simpler are consuming more RAM than you’d like to expect, but the consumption doesn’t increase further once all intended frames are loaded. Let me know if this isn’t the case.
This is simply the result of decompressing long duration/high resolution H264 encoded videos. Please see this thread for more context, and let us know if you have any further questions!
