• How can I record audio from output device using ffmpeg ?

  17 mai 2020, par Nimeth

  I'm building an app (Android and iOS) that user could sing MV Karaoke over HLS video streaming. To produce a final recording for a user, I use ffmpeg to mix the audio stream taken directly from the song with user's recorded vocal and video. But the big challenge is when there are silence periods during recording due to low internet bandwidth, there would be a significant lag time in the final mixed output which is not acceptable for users. How can I use ffmpeg to live record audio being played by another player and use it to mix with user's vocal ?

  I am merging an mp3 audio file with mp4 video file using this command.

   exec("ffmpeg -i 1.mp3 -i 1.mp4 -acodec copy -vcodec copy -shortest final.mp4")

  Final video is fine. Mp3 audio file sound is merge successfully with mp4 video. Video is being play on all browsers but on firefox it is not playing. It is giving error that 'Video cant be played because the file is currupted'. Can you please tell me what's the issue.
