推荐答案

那么标签是指标题、艺术家、专辑等内容吗?在这种情况下，您可以尝试 JCodec 中提供的新 API (org.jcodec.movtool.MetadataEditor).它还有一个 CLI (org.jcodec.movtool.MetadataEditorMain).

So by tags you mean things like title, artist, album etc? In this case you can try the new API available in JCodec (org.jcodec.movtool.MetadataEditor). It also has a CLI (org.jcodec.movtool.MetadataEditorMain).

以下是基本用法:

# Changes the author of the movie
./metaedit -f -si ©ART=New\ value file.mov

或通过 Java API 做同样的事情:

or the same thing via the Java API:

MetadataEditor mediaMeta = MetadataEditor.createFrom(new
    File("file.mp4"));
Map<Integer, MetaValue> meta = mediaMeta.getItunesMeta();
meta.put(0xa9415254, MetaValue.createString("New value")); // fourcc for '©ART'
mediaMeta.save(false); // fast mode is off
