Mp4ReaderSource filesystem_error due to canonical error

[palak-ckar]

Describe the bug
Calling boost::filesystem::canonical(path) on a non-existent path causes a crash with the following error:

what(): boost::filesystem::canonical: No such file or directory: "some/nonexistent/path"

Since canonical requires the path to exist, it throws a boost::filesystem::filesystem_error, leading to an unexpected crash instead of providing a fallback or error-handling mechanism.

Steps to reproduce the behavior

• Pass a non-existent path to boost::filesystem::canonical, e.g., "/some/nonexistent/path".
• Run the application.
• Observe that the program throws an exception and crashes.

Expected behavior
Instead of crashing, canonical should provide a way to handle non-existent paths gracefully. A better approach would be:

• Returning an error code or exception (try catch) that can be caught without a crash.
