(copy lion macports > snow leopard) dyld: Library not loaded: /System/Library/Frameworks/CoreMedia.framework/Versions/A/CoreMedia

[mrkapqa]

Hello ,

i do use Firefox ESR (45 - 52 ) as browser and use quite some extensions. For Youtube i do use "Watch with MPV" , and on OSX , i had a working mpv version 0.26 that enabled the firefox extension to access properly the mpv client.

However, lately, whenever i tried to install mpv with macports (on Lion, or Mavericks, or other OSX) it would not function anymore.

As i could not localize the error, i resorted to copying the working /opt/local/ directory from the functioning partition over to the other partition, where i would like enable the same functionality.

This works well when i go "upstream" , eg. from Lion upwards (at least tried with Mavericks);

i do have several SL partition where i would like to "implement" this feature aswell, however when i copy over the /opt/local/ and /Macports (Programs) directory , afterwards, upon evoking "mpv" command, i get the following error

dyld: Library not loaded: /System/Library/Frameworks/CoreMedia.framework/Versions/A/CoreMedia

Referenced from: /opt/local/lib/libavcodec.58.dylib Reason: image not found

Trace/BPT trap

i do understand that this CoreMedia.framework is not present in the Frameworks on Snow Leopard. Can i just copy it over from the Lion partition (which i would rather avoid) or is there another way to please this libavcodec.58.dylib?

Thank you very much.
