Description
FFmpeg version: N-79585-g268b5ae
Summary of the bug:
When remuxing the audio file, it creates an empty mov_text stream that wasn't present in the original file. The issue persists when muxed into an mp4 file, and I've tried nothing else.
How to reproduce:
Mux the audio file (https://www.datafilehost.com/d/f857df5c) back into a new m4a file or mp4 file. Below is my sample, remuxing to m4a. Not sure if it's useful, but that audio file was generated by re-encoding a flac file I had handy using foobar2000's free encoder pack.
