  • How to open a HEIF (.heic) image ?

    14 décembre 2022, par Jean-Milost Reymond

    For a c++ project, I need to open and show a HEIF (.heic) image. What I know (if I'm right) is that the HEIF images are based on the ffmpeg standard, and requires a H265 codec to be read.

    



    I found several open-source H265 codecs :

    



    



    I can open and show H265 encoded video files with each of them, but I'm unable to simply open, show or convert a .heic image. All of them return an error, or just do nothing.

    



    To be honest I'm a little puzzled, because the HEIF standard seem to be a well kept secret. I'm unable to find a relevant info that could allow me to walk to a solution. Those I found are just tricks and workarounds, like e.g. forcing the device (I'm speaking here about the Apple iPhone using the new iOS11) to generate a jpg image instead of a heic, or using a third party application like dr.fone. Of course these solutions are irrelevant for me.

    



    So, somebody can tell me which codec I should use with a .heif image, and how I can use it to open it ? Or are there open source libraries or examples that allow to manipulate this type of image file ? Somebody can point me to the good direction ?

    


  • Prevent libavformat (FFmpeg) from adding "ENCODER" tag to output / stripping tags

    1er mars 2014, par Wyatt8740

    I made a bash script that transfers audio or video metadata from one file to another, regardless of media container format, via FFMpeg. My problem is that FFMpeg consistently adds a 'ENCODER' tag.

    Example :

    Before running through FFMpeg :

     File : track01.cdda.flac

      Metadata:
    
    ALBUM           : Wish You Were Here
    
    ARTIST          : Pink Floyd
    
    COPYRIGHT       : 1975 Harvest Records
    
    DATE            : 1975
    
    GENRE           : Experimental Rock
    
    TITLE           : Shine On You Crazy Diamond
    
    track           : 1

    After running through FFMpeg :

     File : track01-iphone-alac.m4a

      Metadata:
    
    ALBUM=Wish You Were Here
    
    ARTIST=Pink Floyd
    
    COPYRIGHT=1975 Harvest Records
    
    DATE=1975
    
    GENRE=Experimental Rock
    
    TITLE=Shine On You Crazy Diamond
    
    track=1
    
    ENCODER=Lavf55.12.100

    So really, I want to either force FFMpeg to not add the 'ENCODER' tag, or I want to strip that tag off afterwards. Is there a way to do this ? I really don't want to spend hours trying to compile FFMpeg again on my Pentium 4 HT - the only working computer I have at the moment. I'd prefer not to have to use another program unless it's related enough to FFMpeg or MPlayer/Mencoder that I won't have to install anything new if I have those installed.
