问题
I need to be able to at very least read and preferably write id3 tags connected to an mp4 video file.
I've looked into using getId3() but it's got so many functions that finding those applicable to mp4 video files is difficult and the write demo files don't work on mp4 files
回答1:
ID3 tags, as such, are only generally used on MP3 streams. I believe that MPEG 4 uses its own metadata format (within the meta atom). For details, see http://atomicparsley.sourceforge.net/mpeg-4files.html.
