• FFmpeg: Fix possible deadlock leading to producer not being cleaned up correctly

This is the first patch release for 2.3.

Primarily this contains a crtical fix to provide support for flash templates to be used after the flash player EOL at the end of 2020.
For more information on the issue see: #1352

Thanks to @silid for developing the fix and @didikunz for documenting the process and being a key member of chasing for these releases to be made

See the attached PDF, or the copy in the Zip for steps on how to prepare your system.

Producers

Fixes

• Flash: Use proper file urls when loading templates, to allow it to work after Flash Player EOL
• FFmpeg: Various HTTP playback improvements

This is a critical fix for the 2.0.7 release, to provide support for flash templates to be used after the flash player EOL at the end of 2020

For more information on the issue see: #1352

This has been built to be as close as possible to the previous 2.0.7 release, to minimise any risk of deployment.
