    Le lecteur ne fonctionne pas sur Internet Explorer

  • Join videos command line debian [on hold]

    2 avril 2014, par Roman

    Good evening

    I'm looking for a solution for the following problem :
    I have to join multiple video files (webM-format) with different settings (resolution, fps, ...) into one final file. I should also add an additional audio-track who's exactly as long as all video files together (wav-format).

    I've tried it with ffmpeg and concat like this :
    ffmpeg -i "concat:file1.webm|file2.webm|file3.webm" -vcodec libvpx -s 1280x720 -i track.wav -acodec libfaac -ab 128k -async 10 final.webm

    Result : Worked fine, but just with the first video file. All the others were ignored by ffmpeg.

    Have you any other solution for this problem ?

    Best Regards,
    Roman Ackermann

  • How to start live streaming on Mac using FFMPEG ?

    3 août 2014, par Alexandra Chis

    I am working on a MAC OS X Lion 10.7.5.

    How to properly install FFMPEG ?

    What I did :

    ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
    
brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

    and even (I think this should work, but it doesn’t)

    brew install ffmpeg

    Nothing works...I can’t list the inputs, I can’t start the streaming from the USB camera, I can’t do anything.

    ffmpeg -f video4linux2 -s 320x240 -i video="USB cam":audio="USB mic" -f oss -acodec libvorbis -vcodec libvpx -f webm http://localhost:1234/streaming

    The errors I get look like this :

    unknown input format 'video4linux'

    and the same happens for alsa, openal, vfwcap etc.

    So did anyone try live streaming with FFMPEG from MAC ?
    How to install FFMPEG so that is supports video4linux2 or v4l2 or any input format at all ? How to list the devices (USB webcams or integrated webcams) ?

  • Convert and stream videos [on hold]

    26 septembre 2013, par user969068

    I am going to develop a php script on linux based server which will be used to upload videos on server and stream to users. I have seen many open source free/paid libraries available with flash,html5 etc players. After research I have decided to go with ffmpeg to convert videos and use jwPlayer with RTMP protocol to stream videos.

    I am not much familiar with streaming concept but I have researched a lot on this subject since few days, so last I thought to ask here if I am going the correct way to achieve my goals, which are listed below :

    1. My main concern is to start streaming videos as soon page is loaded.
    2. Convert videos after upload ( Found ffmpeg for this purpose is well suited )
    3. Seeking video should be faster (which after searching I found is good with RTMP protocol)

    Please can someone guide me if I am going in the right direction by choosing ffmpeg, jwplayer with RTMP protocol. Thanks a lot for any guidance.
