2020-01-15 Thread Andrew Brezovsky
I have been trying to modify the handler_name metadata field of an audio stream in a video file within an mp4 container. However, ffmpeg seems to be discarding the handler_name field and replacing it with a generic "SoundHandler" value. While the values in the input and output read-outs are correct
