  • linking libavcodec os x ffmpeg ApplicationServices.framework

    30 décembre 2015, par Grady Player

    Here is my error : (newer version of ffmpeg)

    dyld: Library not loaded: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices
    
  Referenced from: /Users/me/path/to/lib/libavcodec.dylib
    
  Reason: Incompatible library version: libavcodec.dylib requires version 64.0.0 or later, but ApplicationServices provides version 1.0.0

    I have read the questions on SO that say you need to link ApplicationServices.framework... which I have done, it makes no difference...

    I have searched for other versions of that framework :

    $ mdfind ApplicationServices.framework
    
/System/Library/Frameworks/ApplicationServices.framework

    just one...

    so then inspecting frameworks...

    $ otool -L /System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices 
    
/System/Library/Frameworks/ApplicationServices.framework/Versions/A/ApplicationServices:

    and libavcodec

    I am compiling everything with -mmacosx-version-min=10.7

    so maybe a bug in the toolchain ?

  • ffmpeg concatenate clips with broken timecode

    19 septembre 2018, par Linus679

    I’ve just received some Blackmagic footage and some of the clips are separated into chunks because of dropped frames. So let’s say I have a set of clips that looks like below for a Clip 12.

    0100_C0012_001,
    0100_C0012_002,
    0100_C0012_003,

    Is there a way to create new clip from the 3 with the name 0100_C0012 ? Also, I have to actually concatenate the clips via timecode rather then the name as the numbers seems to break at points for some reason.

    Thanks for any help.

    The info about one of the clips is as follows :
