Sorry to add my question to this, but what actually is the -activation_bytes string. Where do I find that? My file is recognised with ffmpeg -i example.ax But, trying this command ffmpeg -activation_bytes 62689101 -i Volume1.aax -vn -c:a copy -v \ debug output2.mp4 results in this error Opening an input file: Volume1.aax.
