I know this should work since the exact line does work for other files. But the result with these is a silent video.
I checked the audio file being used and it seemed fine when played. but I did get a weird warning when creating it. Basically I have 2 audio tracks, one is overlay music and the other is talking. I create the combined audio with this command.
ffmpeg -y -i /var/www/temp/audioTrack.mp3 -i /var/www/temp/musicTrack.mp3 -filter_complex amerge -c:a libmp3lame -q:a 4 /var/www/temp/combined.mp3Here is the output from the second command.

[libmp3lame @ 0x1601000] Trying to remove 1152 samples, but the queue is emptyAs I said the output audio file sounds correct.
The Music and Audio tracks are created with AudioSegment in python from the pydub library. I’ve used this before with no issues. The code for this is as follows.
sound = AudioSegment.from_mp3(audio)
introSilence = AudioSegment.silent(duration=introLength)
creditsSilence = AudioSegment.silent(duration=creditsLength)
increasedAudio = sound + 12
talking = introSilence + increasedAudio + creditsSilence
talking.export(audioTrack, format="mp3")
mus = AudioSegment.from_mp3(music)
introMusic = mus[ : introLength]
videoMusic = mus[introLength - crossFade : introLength + videoLength + crossFade]
creditsMusic = mus[totalLength - creditsLength : totalLength]
lowerMusic = videoMusic - 6
totalMusic = introMusic.append(lowerMusic, crossfade=crossFade).append(creditsMusic, crossfade=crossFade).fade_out(fadeOut)
totalMusic.export(musicTrack, format="mp3")Here is the output of
