merge audio and video(having audio) using ffmpeg command I run below command for this question that is working and give output file in mp4 but that file is not open in QuickTime Player but open in VLC Player and not open in other PC also.

Command:

ffmpeg -i EnergyVideo.mp4 -i EnergyAudio.mp3 -filter_complex \
"[1:a]volume=enable='between(t,27,33)':volume=0, volume=enable='between(t,38,42)':volume=0[1a];[0:a][1a]amerge=inputs=2[a]" \
-map 0:v -map "[a]" -c:v copy -c:a libvorbis -ac 2 -shortest energyvideooutput2.mp4
