483: Fix FFmpeg 6.0 crashes when loading 50+ clips and stressing the timeline
Linked issues
Fixes #483
Summarize your change.
No longer using the MovieFFMpeg global context pool (since FFmpeg 6.0)
Describe the reason for the change.
Rationale: The global context pool was based on the premise that a context could be opened and closed multiple times.
However, with FFmpeg 6.0, this premise is no longer valid and was causing crashes.
As per the FFmpeg 6 documentation: https://ffmpeg.org/doxygen/trunk/deprecated.html:
"Opening and closing a codec context multiple times is not supported anymore – use multiple codec contexts instead."
Describe what you have tested and on which operating system.
