No audio track in exported movies
Posted: 25 Oct 2019 02:43
I'm trying to export a movie of a recording in heli-x v8, and the resulting .mp4 file never has any audio. I've tried various video players/utilities and all of them agree that the .mp4 file simply has no audio track:
I've tried installing heli-x on multiple Linux machines, and they all act the same: the audio plays though the speakers during the export operation, but there's no audio in the .mp4 file. How do I enable exporting of audio in the .mp4 file?
I also tried exporting to .avi, but that doesn't work at all. It only generates ~1400 bytes in the output file, and none of the video players I've tried think it's a valid avi file.
Code: Select all
$ ffmpeg -i movie_001.mp4 -hide_banner
