  • live video streaming not playing on dash.js player using ffmpeg, nginx-rtmp in raspberry pi

    15 août 2016, par sparks

    I am trying to stream a live video from raspberry pi & pi camera module to web browser.But the video doesn’t play.I am using Nginx-rtmp and ffmpeg to process the video. On the client side i use dash js player trying to play the video but no luck.I see the warning on the terminal

    [flv @ 0x2c3b950] Failed to update header with correct duration.

  • Fluent-ffmpeg "not a suitable output format"

    5 septembre 2015, par J4G

    I’m using the fluent-ffmpeg module for Node.js to convert audio files. I have a .mp3 file that I’d like to convert to .wma

    Here’s what that looks like :

    var proc = new ffmpeg({
    
   source: 'file.mp3',
    
   nolog: false
    
}).toFormat('wma')                                                
    
  .saveToFile('file.wma', function(stdout, stderr)
    
{                                                 
    
    console.log(stderr);
    
});

    Unfortunately, I get the error :

    Requested output format 'wma' is not a suitable output format

    This is the entire error log :

    I know this isn’t an ffmpeg issue because

    ffmpeg -i file.mp3 file.wma

    Works fine. Any ideas ?

  • node js (or other) as streaming server

    20 décembre 2013, par Abdul Ali

    Apologies if a simple question but cannot find anything helpful . Am also new to the streaming concept.

    Goal is to set up a server which keeps on listening for data on a speific port. The user will be sending sequence of images from their iphone (# of images unknown).

    when the data is receieved, ffmpeg should start to get data from that port (as input) and send those images to ffserver to be streamed as a live video.

    did try Nginx-Rtmp module but the iphone developer have informed that in iphone, only ip and port can be given to open a stream (and no other part of the url can be given e.g. streamname and application name in case of nginx-rtmp)

    Any help and guide will be appreciatd that what can be used to set up a free and very simple sever that simply receives the images which ffmpeg can capture and send to ffserver .
