[FFmpeg-user] MP4s for music

[Mark Filipak]

I ask for advice from the learned folk of FFmpeg. The following script works. The mp4 plays -- even 
PowerDVD plays it. Song selection is available via chapters. However, I wonder about the wisdom of 
my approach and whether there's a better, more comprehensive method.

ffmpeg^
  -i "c:\Ashra, Correlations [1979] chapters.txt"^
  -i c:\01.WAV^
  -i c:\02.WAV^
  -i c:\03.WAV^
  -i c:\04.WAV^
  -i c:\05.WAV^
  -i c:\06.WAV^
  -i c:\07.WAV^
  -filter_complex "[1:0][2:0][3:0][4:0][5:0][6:0][7:0]concat=n=7:v=0:a=1[out]"^
  -map_metadata 0 -map "[out]"^
  -c libmp3lame -compression_level 0^
  "c:\Ashra, Correlations [1979].mp4"

Issue #1: I doubt my car's stereo will play mp4s.

Issue #2: I'm aware of *.m3u playlists however many players insert brief silence between songs. 
That's a non-starter for much of my music.

Suggestions will be gratefully accepted.
