mlt @6.4.1_2 error: use of undeclared identifier 'ReSampleContext'

After a general upgrade, ports attempts to rebuild mlt (and 2 others) but fails. Please see the attached main.log

See #56414

looks like another port that fails to build due to the ffmpeg upgrade.

[tehcog (tehcog)]

This patch works, but similare may be needed for: transcode @1.1.7+x11 & strigi @0.7.8

[ddennedy (Dan Dennedy)]

More than likely the ffmpeg upgrade broke transcode like it did MLT, but not sure about strigi. This was already anticipated and addressed in MLT upstream several months ago; however, the mlt port was not updated for the last release. The resolution for macports then was simply to upgrade MLT. However, I do not believe transcode upstream is maintained any longer; so, getting that fixed is likely a big job to patch the source. Sorry, I am not volunteering to do that; I have my own projects to maintain.

In 745ebf602ab8d2b02ccb4eb5fef8b5580f62dca9/macports-ports (master):

mlt: update to 6.8.0

• convert to github PortGroup
• add my github handle
• build only against sdl2 (not 1.2) if not disable_sdl variant
• add dependencies on fftw-3 and libebur120 for new filters
• supersedes patch in #56414
• resolves ffmpeg compile error reported in #56412

[tehcog (tehcog)]

I may be mistaken, but this looks like it is fixed (transcode as well)

The git commit message is supposed to have the complete URL to the Trac ticket in order to close the ticket.
