  • Live transcoding and streaming of MP4 works in Android but fails in Flash player with NetStream.Play.FileStructureInvalid error

    23 juillet 2012, par user831052

    Recently I had a task to use ffmpeg as a transcoding as well a streaming tool. The task was to convert the file from a given format to MP4 and immediately stream it, by capturing it from stdout. So far so good. The streaming works well with the native player of android tabs as well as the VLC player. The issue is with the flash player. It gives the following error :

    NetStream.Play.FileStructureInvalid : Adobe Flash cannot import files that have invalid file structures.

    ffmpeg flags used are

    $ ffmpeg -loglevel quiet -i somefile.avi -vbsf h264_mp4toannexb -vcodec libx264 \
    
-acodec aac -f MP4 -movflags frag_keyframe+empty_moov -re - 2>&1

  • 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.
