I just found that, if I have an AAC audio file (technically M4A), and if I added the ID3 tag 2 (aka ID3v2), then the audio file will failed to be converted by ffmpeg.
It can be either converted to mp3
- using DeadBeef audio player, or
- remove the ID3v2 tag then convert
So, how to add the metadata like ID3 tag? Use the Kid3 and add the Tag 3 (aka APE tag). This will not affect how ffmpeg to read the file.
In the previous post (1 year ago), I mentioned the hibernation issue. I believed that it was related to the NVidia graphic card. Related forum can be found here.
But these few days, I notice that whenever I shut down the laptop, it will show the systemd messages. Previously, if I did suspend my laptop, then resume, then shut down will show only black blank screen, until the power off. I believe that the graphic card issue is being fixed with the recent update.
I am now using linux-lts 4.9.13-1 and nvidia-dkms 378.13-2
