Hard coded path for mediainfo

[micolous]

There's a hard coded path to /usr/local/bin/mediainfo in autodetect_file.c:

caption-inspector/src/utils/autodetect_file.c

Line 52 in 476326f

char* mediaInfoInvokeStr = "/usr/local/bin/mediainfo";

As a result, if you have installed mediainfo in another directory that is in the PATH (eg: /usr/bin), such as installing it via apt install mediainfo, caption-inspector won't find it.

The Docker build appears to work around this by moving the binary:

caption-inspector/Dockerfile

Line 62 in 476326f

COPY --from=base /usr/bin/mediainfo /usr/local/bin/mediainfo

The easy fix is to change this to:

char* mediaInfoInvokeStr = "mediainfo";

But it may also need a fix-up for the Docker container which puts the binary elsewhere.
