======= Media Handling =======

Handling media files such as pictures and videos is a task that pops up often
and Linux has a host of great CLI tools for doing so very quickly and easily.
Mastering these tools will allow you to do things like, flipping an ''%%.MOV%%''
video or scrubbing the exif data of a photo, or resizing a photo to the best
resultion under a set size in seconds without interrupting what you were
actually trying to accomplish.

The following are commands for tasks I have ran into.

===== Flipping Videos =====

To vertically flip a video and retain its stream settings use a view filter in
ffmpeg by doing the following:

<code bash>
ffmpeg -i in.MOV -vf "vflip" -c:a copy out.MOV
</code>

To flip a video file that has been flipped to the correct orientation by use of
the exif orientation value, run the command twice.

<code bash>
ffmpeg -i in.MOV -vf "vflip" -c:a copy out1.MOV
ffmpeg -i out1.MOV -vf "vflip" -c:a copy out.MOV
rm out1.mov
</code>

===== Rotating Photos =====

When rotating photos its also usually desirable to dump the exif orientation
tag. To do this:

<code bash>
exiftool -Orientation= /path/to/file/or/dirs -overwrite_original
convert file.jpg -rotate -90 out.jpg
