Summary of the bug:
I would like to be able to play all aac audio files (.m4a) gaplessly ,
i.e. without gaps or other interruptions.
Occasionally, the transition from one file to another is not smooth, and I
am supplying sample media where this is the case.
I am submitting the 2 files referenced below, along with more details in
"aacGaplessFail.txt".
Version unknown, because I am experiencing this via mpd which uses an
ffmpeg decoder plugin with unknown origin. Reproducing quote below
supplied by mpd developer.
How to reproduce:
{{{
ffmpeg -f concat -safe 0 -i concat.txt -c copy out.m4a
... where concat.txt contains:
file '01 Track01 aac gapless fail.m4a'
file '02 Track02 aac gapless fail.m4a'
When I played out.m4a, I heard the same glitch as with MPD
}}}
