M4Bs modified by Tone 0.1.6+ will not show when played in mpv #79

I'm going to take a look. Could you provide a non copyrighted example file and the commands to reproduce this, would save me a lot of time. |

Hello,
Thank you for your reply!
I checked, but all my m4b contain copyrighted or private materials. I tested on my system with 3 different m4b from different sources, and the problem persisted. I could maybe send you an m4b I create myself, but I am unsure whether that would be useful.
Here is the steps I followed for each test:
- create copy of file
`cp linux_org.m4b linux.m4b`
- - check tone version
`tone -v`
- - change metadata w. tone 0.1.5
`tone tag linux.m4b --meta-genre=Audiobook`
- - open file in player -> plays with window
`mpv linux.m4b --force-window=yes`
- change version, curl, tar, mv, check tone version, repeat
- - open file -> plays without window (unexpected)
- - "fix" file with ffmpeg, removes some metadata and a lot of new streams
`ffmpeg -i linux.m4b -map 0:0 -c copy linux_fix.m4b`
- - open file in player -> plays with window
- change version, repeat, results for all tested same as before

Ok, I reproduced it with one file, but it's not that easy. Usually I use the following commands to reproduce it on a non-copyrighted file: # create a 5 seconds sample silence
ffmpeg -ar 48000 -ac 1 -f s16le -i /dev/zero -t 5 -y sample.wav
# convert wav to m4b
ffmpeg -i sample.wav -f mp4 sample.m4b
# download a sample cover
wget -c https://picsum.photos/id/237/500/500 -O cover.jpg
# embed the cover into the sample
ffmpeg -i sample.m4b -i cover.jpg -map 0 -map 1 -c copy -disposition:v:1 attached_pic -f mp4 ready.m4bNow, if I use tone to tag this file, everything works flawless. |

Hello, thank you for your reply. I used it as a base and created a non-copyright file. Important: skipping the embed cover step seems key! Github does not support m4b attachments, so I attached two silent m4b files as zip.
Here are my steps for creating the m4b, I wanted to get as close to my copyrighted file in terms of metadata as possible, so there are likely some unnecessary steps. click to show

Hello. I am not very familiar with audio formats, so please bear with me. If this is a bug in mpv and not tone, please close the ticket.
I use debian based. x64.
mpv:
Tone version works with mpv:
Tone version does not work with mpv:
I did not test 0.1.7, 0.1.9, and 0.2.0.
I use tone to add metadata to my m4b files. Today, I checked if there is a new version as I had been using v1.4 for some time. I used 2.3 to modify my audio. Afterwards, it would still play in mpv but the window would be hidden/cannot be seen/there is no GUI.
ffprobe shows this:
If I do this, the file opens as expected again:
ffmpeg -i "linux.m4b" -map 0:0 -c copy "linux_fix.m4b"But it removes some of the metadata.
If I use tone 0.1.4 or 0.1.5, no new stream is created when changing the metadata:
As tone 0.1.5 does everything I need, I will just use the old version for now, but I am curious what the issue is.
If you need more data, I am happy to provide. Thank you for developing this amazing tool!
