I’m trying to convert an aax audible file to mp3 or mp4 with not success.
I’ve tried this command, and it fails. ffmpeg -activation_bytes 1CEB00DA -i test.aax -vn -c:a copy output.mp4 and this one ffmpeg -activation_bytes 62689101 -i Volume1.aax -vsync 2 -c:a copy output.mp4 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f8f3c808600] [aax] file checksum == d72f1f04e3c73d0bc68e742db1bc69b58dc3a500 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f8f3c808600] [aax] mismatch in checksums! [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f8f3c808600] error reading header Volume1.aax: Invalid data found when processing input With the same error. Obviously the trick is the activation_code - where do I get that from ???? Now interestingly, when I try this command. ~/Downloads/ffmpeg -i Volume1.aax -vsync 2 -c:a copy output.mp4 It … almost works … in that it produces a file that also contains the cover art, and loads in to a player - but is silent… The first error/warning is this [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fd3a1000800] [aax] file checksum == d72f1f04e3c73d0bc68e742db1bc69b58dc3a500 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fd3a1000800] [aax] activation_bytes option is missing!
