Jérome Eertmans 74ddefe519 chore(deps): remove subprocess calls to FFMPEG with av (#335)
* chore(deps): remove subprocess calls to FFMPEG with `av`

Linked to the progess made in https://github.com/ManimCommunity/manim/pull/3501.

The following PR aims at reducing subprocess calls for security and speed reasons. Also, with https://github.com/ManimCommunity/manim/pull/3501 is merged, FFMPEG should not be needed anymore as it is part of `PyAv`.
