 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.
