Hi Tim,

As Jim was saying it's unfortunately a little difficult from what we can
see if it's ffmpeg causing you this trouble.

The stack trace seems to point at a dynamic library called DiskUtil and an
ext4 device. It's all a guess but I think the best starting point may be
the software developers over there, as this seems to me like the
application is trying to mount the RAW file you mentioned.

Best of luck.
