Hi.
I'm splitting a .wav file into a set of chainable .ogg files all having 1
second duration.
I'm using input flags: "-ss n -t 1"
When I concatenate these ogg files, the resulting clip is slightly longer than
the original. Is it because the minimal nb_sambles in ogg frame is 128 and a
set of ogg
frames cannot contain exactly 44100 samples?
</dev/null ffmpeg -y -ss 0 -t 1 -i test.wav -af "ashowinfo" test1.ogg
# pts:44032 nb_samples:68
</dev/null ffmpeg -y -ss 1 -t 1 -i test.wav -af "ashowinfo" test2.ogg
# pts:44032 nb_samples:68
</dev/null ffmpeg -y -i "concat:test1.ogg|test2.ogg" -af "ashowinfo"
test5.wav
# pts:88132 nb_samples:128
88132 + 128 != 88200
ffprobe test5.wav
# Duration: 00:00:02.01
