    dashenc: set DASH related options for the subsequent matroska muxer when using webm

    This patch is inspired by the ffmpeg webm_chunk muxer and fixes that all resulting
    
tracks have the same track number.

  • Video - extract image from DASH m4s file using ffmpeg

    6 July 2017, by Yogevnn

    I’m trying to create a thumbnail from a dash stream m4s file.

    I have the mpd, init.mp4 file and the m4s files.

    I have the code using nodeJS ffmpeg package that extracts image from an mp4 file:

    try {
    
var process = new ffmpeg('video.mp4');
    
process.then(function (video) {
    
    // Callback mode
    
    video.fnExtractFrameToJPG('C:\\files\\nodejs', {
    
        start_time: `1:50:30`,
    
        frame_rate : 1,
    
        file_name : 'my_frame_%t_%s'
    
    }, function (error, files) {
    
        if (!error)
    
            console.log('Frames: ' + files);
    
    });
    
}, function (err) {
    
    console.log('Error: ' + err);
    
});
    
} catch (e) {
    
console.log(e.code);
    
console.log(e.msg);
    
}

    But because i’m reading my files from a dash-stream i’m getting an m4s files.

    I’ve tried to convert the m4s format into mp4 and then use the code above, but the ffmpeg( fluent-ffmpeg to be exact) is returning an error message

    an error occured: ffmpeg exited with code 1:
    C:\files\nodejs\testFiles\000000.m4s: Invalid data found when
    processing input

    The code i used to convert is:

    var proc = new fluent({source: "C:\\files\\nodejs\\testFiles\\000000.m4s", 
    
nolog: true})
    

    
//useless i think - not working
    
//proc.setFfmpegPath("C:\\files\\ffmpeg-20170620-ae6f6d4-win64-static\\bin")
    

    
proc.withSize('50%').withFps(24).toFormat('mp4')
    

    
.on('end', function(){
    
console.log('file has been converted successfully');
    
})
    
.on('error', function(err){
    
    console.log('an error occured: ' + err.message);
    

    
})
    

    
.saveToFile("C:\\files\\nodejs\\new.mp4");

    Is it possible to convert a single m4s file to mp4?

    If not, what is the right way of converting m4s to mp4 using ffmpeg with nodejs?

    I couldn’t find any reference for that, but if it is possible to extract an image directly from the m4s file i think it will solve the problem faster.

    It is possible to use this site to download all the *.m4s files, mpd and init.mp4 files using the network section (f12 in Chrome browser) and check the code.

  • Dash timestamp: 41390056 is out of range for mov/mp4 format

    26 October 2017, by mike

    I’m trying to convert a aac stream to dash. The issue is that I get a lot of errors as below(though it seems to segment it into multiple files but I get errors on the player too). The question is why do I get these errors and how can I fix it? If I simply convert "copy" it into to a single mp4 file it works without error.

        ffmpeg -i  "a.mkv" -y -map  0:1 -c:0 copy -min_seg_duration 1000000 
    
-use_timeline 1 -use_template 1 -init_seg_name init.mp4s 
    
-media_seg_name  "\$Number\$.mp4s" -adaptation_sets "id=1,streams=0"
    
-remove_at_exit 0  -f dash -dash 1 
    
"out/stream.mpd" -loglevel error

    Output

    [mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40475608 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40764376 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 40860664 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41149432 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41390056 is out of range for mov/mp4 format
    
[mp4 @ 0x7fbb70819600] Application provided duration: -32 / timestamp: 41823208 is out of range for mov/mp4 format

    Copy to a single MP4 works just fine
    ffmpeg -i "a.mkv" -y -map 0:1 -c:0 copy -f mp4 -dash 1 "out/out.mp4" -loglevel error
