  • Pushing data to web-browser while processing input from ffmpeg

    6 septembre 2013, par Stacked

    I want to push output of this directly to the user using PHP/Python :

    wget -qO- "http://my-video-stream-input.url/here" | ffmpeg -i pipe:0 -ab 192000 -acodec libmp3lame -map_metadata -1 -vn 1378457645_myfile.mp3

    The above command takes the input stream and converts on-the-fly it to audio without waiting for full-file to download, this works perfectly at terminal. Now, I need to push the ffmpeg processed output audio to the web-browser, once again on-the-fly without completing the full transcode, like :

    Wget->ffmpeg->Web-browser in real-time

    I tried the below in PHP but this results in 0 byte file-downloads :

    $cmd = "wget -qO- "http://my-video-stream-input.url/here" | ffmpeg -i pipe:0 -ab 192000 -acodec libmp3lame -map_metadata -1 -vn 1378457645_myfile.mp3";
    
header('Content-type: audio/mpeg');
    
header("Content-Type: application/octet-stream");
    
header("Content-Disposition: attachment; filename=\"1378457645_myfile.mp3\"");
    
passthru($cmd);

    Adding 2>&1 to the $cmd shows downloads a 3.6 KB file with following

  • How to choosing audio stream

    5 septembre 2013, par user2696962

    I want to choose the first audio stream. but for some reason, it's not working. it's always choosing the last audio stream

  • FFMpeg - Merge multiple rtmp stream inputs to a single rtmp output

    5 septembre 2013, par Paulo Miguel Almeida

    I'm trying to combine/merge two rtmp streams and then publish 'em to another stream

    Ex. :

    ffmpeg -i rtmp://ip:1935/live/micMyStream7 -i rtmp://ip:1935/live/MyStream7  -strict -2  -f flv rtmp://ip:1935/live/bcove7

    The scenario is the following, I got a stream which comes from an user's microphone that
    is the first one (micMyStream7) and I also got a stream from another user but this one has audio and video(MyStream7).

    As they are talking to each other when a user is speaking, the other one would only be listening to and vice versa.

    My idea is to set up a third stream called (bcove) which would "merge" both of them so that I could have spectators who would only be listening to the entire conversation between them.

    This is the log that ffmpeg printed although I couldn't recognize any message which helped me out.

    paulo@paulo-desktop:~$ ffmpeg -re -i rtmp://ip:1935/live/micMyStream7 -i rtmp://ip:1935/live/MyStream7  -strict -2  -f flv rtmp://ip:1935/live/bcove7
