  • Animated line chart with pandas, matplotlib and ffmpeg

  • Create HLS streamable audio file from mp3

    15 août 2023, par isADon

    I am using following command to create a hls aac audio file for web streaming

    



    ffmpeg -y -i song.mp3 -c:a aac -b:a 128k -f hls -hls_time 7 -hls_list_size 0 -hls_segment_filename file%d.m4a playlist.m3u8


    



    This command works only with some audio files. With many mp3 files I receive following output :

    Notice the "mp3float overread" message.

    



    It results in a single file0.m4a file without splitting it up after every 7 seconds as specified.
This is an example audio file I am trying to convert to a aac hls stream that results the mentioned problem : https://incompetech.com/music/royalty-free/index.html?isrc=USUAN1100474

    



    How can I convert an audio file to a web friendly hls stream with ffmpeg ?
