Implementation details about mp4decrypt

[tra4less]

In an environment where disk usage is simulated using memory, I am using mp4decrypt. I attempted to delete the portions of the original file that have already been read during the execution of mp4decrypt. However, I encountered errors in doing so, as some blocks were being read twice. Can you provide some insights into the patterns, such as whether there is an initial random reading of fixed-sized blocks followed by sequential reading of other blocks?
