ffmpeg mp4 video funktioniert nicht auf dem iphone

Ich habe ffmpeg auf meiner Website, damit Benutzer verschiedene mp4-Dateien erstellen können, und sie funktionieren auf allen Geräten gut, mit Ausnahme einer meiner Konvertierungsfunktionen, bei der das Video nicht auf meinem iPhone abgespielt werden kann. Das gleiche genaue Video funktioniert gut in Chrom auf meinem Laptop.

Dies ist der Code, der Im verwendet -

// first we merge the audio file with the concat file for images ffmpeg -i '.$thepath .'/audio.mp3 \ -safe 0 -f concat -i '.$thepath .'/paths.txt \ -af "volume=-1dB" -c:v libx264 -vprofile baseline \ -vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2" -t 180 -pix_fmt yuv420p -movflags +faststart -y '.$output.' 2>&1  // now add background music ffmpeg \ -i '.$output.' -i '.$musicpath .'/'.$music.'.mp3 \ -filter_complex "[1:a]volume=-25dB,apad[A];[0:a][A]amerge[out]" \ -c:v copy -map 0:v -map [out] -vprofile baseline -level 3.0 \ -pix_fmt yuv420p -movflags +faststart -shortest \ -y '.$thepath.'/output-'.$v_Id.'.mp4 2>&1 

Da dies auf dem iPhone geschieht und ich keinen Mac habe, kann ich die Ausgabe nicht sehen. Wenn ich den gleichen Code auf meinem Laptop laufe, erhalte ich diese Ausgabe ---
