  • ffmpeg - How to set MIME-type ? [migrated]

    22 octobre 2012, par sasa

    I'm trying to set the proper MIME-type for an AAC file, but this command does not work :

    ffmpeg -i rain.mp3 -metadata mime-type="audio/aac" rainmp3toaac.aac

    but, actualy audio/x-hx-aac-adts is set.

    So, how I can force another MIME-type ?

  • ffmpeg Videos Won't Play Centos

    17 mai 2016, par Dan

    My exported videos from ffmpeg won’t play on anything. I am trying to create a simple slideshow type video from images. It will create the video, the video will add 5 seconds in duration for each image I add but it just doesn’t play on anything. It’s driving me crazy.

    /usr/local/bin/ffmpeg -y -f image2 -r 1/5 -i uploads/img%03d.jpg vid/video.mp4

    And here is the output :
