Hey, I have a use case where I’d like to encrypt the output of MediaMuxer in memory before writing to disk. The general approach is:

• Create a MemoryFile
• Create a CipherInputStream from the `MemoryFile`’s InputStream
• Give the `MemoryFile`’s FileDescriptor to the MediaMuxer constructor
• Create a FileOutputStream from the CipherInputStream
Right now I’m having to use reflection to get the file descriptor from MemoryFile and I’m curious why the getter is unsupported for app usage https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/os/MemoryFile.java#230.

I guess this is the reason (commit where @hide as added) https://android.googlesource.com/platform/frameworks/base/+/e4f60cce8552a565efacf4907242574b9e00492d still makes my use case impossible without reflection though 🤔
