  • IP-Cam / CCTV-Cam Live Streaming on iPhone/iPad

    19 mai 2013, par user1744691

    I want to get stream of an ip-cam on my iPhone/iPad and want to display it on screen. By R&D i found that ffmpeg is the only way to achieve it but i found nothing on ffmpeg. Is there any other way to achieve it or a confirmed way to get compiled ffmpeg on mac please mention that. Material regarding how to use ffmepg or source code example will be highly appreciated.

    Is there nothing built-in framework to achieve it if not then please mention if there is any free framework/sdk to achieve this functionality.

    Thanks

  • 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 ?
