  • mpeg-2 ts video audio skipping - HTTP Live Streaming

    15 août 2012, par Kami Shangool

    I have multiple mp4 streams that I take and convert into mpeg-2 ts format using ffmpeg

    ffmpeg -i 0.mp4 -vcodec libx264 -sameq -acodec libfaac -fflags +genpts -coder 0 -f mpegts 0.ts

    The mp4s range from 1 to n. After converting all of them, I create a manifest file similar to :

    #EXTM3U
    
#EXT-X-TARGETDURATION:4
    
#EXT-X-VERSION:4
    
#EXT-X-MEDIA-SEQUENCE:0
    
#EXT-X-PLAYLIST-TYPE:EVENT
    
#EXTINF:4.000,
    
http://localhost/Nick2/0.ts
    
#EXT-X-DISCONTINUITY
    
#EXTINF:3.97,
    
http://localhost/Nick2/1.ts
    
#EXT-X-DISCONTINUITY
    
#EXTINF:3.97,
    
http://localhost/Nick2/2.ts
    
#EXT-X-DISCONTINUITY
    
#EXTINF:3.97,
    
http://localhost/Nick2/3.ts
    
#EXT-X-DISCONTINUITY
    
#EXTINF:3.97,
    
http://localhost/Nick2/4.ts
    
#EXT-X-ENDLIST

    I've added the #EXT-X-DISCONTINUITY since the I'm trying to get back to back playback of the converted mp4's. The problem is that if I try to use HTTP live streaming, there is a noticeable pop in the audio between files. But that isn't apparent if playing the segments in QT.
    Any thoughts on how I can fix this ?

  • How to write live audio to a file using ffmpeg ?

    29 mai 2013, par user1595858

    What is the command to convert the live audio stream, basically rtmp stream, to a mp3 file ? I am trying this so later I can get audio bytes output which is needed by xuggler to make a video file.
