Description

Hi, apologies if this has been asked before but I couldn't find any info about this, as the title suggests, I'm trying to edit metadata for existing videos (MKV container, H264) I was under the impression that I can use FFmpegFrameRecorder object to open and edit metadata of any videos, yet this doesn't seem to work for me.

Here's the sample code:

FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("absolute-path-to-video", 0, 0, 0); recorder.setVideoMetadata("ARTIST", "ARTIST_TEST");

I was wondering if someone can give me some insights of why this doesn't working.

Thanks in advance!

Research direction
Investigate how FFmpegFrameRecorder handles metadata for existing files. Check the source code of the setVideoMetadata method and see if opening an existing file for reading metadata is supported. Look for documentation or examples of editing metadata in place versus transcode.
