  • Reading file stream from Google Cloud Storage to ffmpeg (using fluent-ffmpeg)

    27 juillet 2018, par ekuusi

    I’m trying to run ffmpeg on a NodeJS backend with fluent-ffmpeg, reading input files from Google Cloud Storage. Everything works fine if I download the file first :

    const file = storage
    
    .bucket('example_bucket')
    
    .file('examplefile.mp4');
    

    
file.download({destination: 'test.mp4'}, (err) => {
    

    
    let command = ffmpeg()
    
    .input('test.mp4')
    
    .duration(10)
    
    .format('mp4');
    

    
    command.save('test_out.mp4');
    

    
});
    

    
res.json([{
    
    message: 'Command sent!'
    
}]);

    But if I try to use a readable stream as the input, it fails :

    const file = storage
    
    .bucket('example_bucket')
    
    .file('examplefile.mp4');
    

    

    
var filestream = file.createReadStream()
    

    
let command = ffmpeg()
    
    .input(filestream)
    
    .duration(10)
    
    .format('mp4');
    

    

    
command.save('test_out.mp4');
    
});
    

    
res.json([{
    
    message: 'Command sent!'
    
}]);

    Here is the full output of ffmpeg when trying to do the conversion. It seems to read the details of the file fine but for some reason it fails, saying "Cannot process video : ffmpeg exited with code 1 : pipe:0 : Invalid data found when processing input"

  • Mpeg Dash code having compilation issues and want to know what to do after the code is built and how to play the .mpd file generated

    11 avril 2013, par niuuuu

    I'm trying to build the DashEncoder code which I downloaded from github https://github.com/slederer/DASHEncoder. Well, I followed all the instructions given in the how to compile dash file. installed Gpac n X264 and compiled both successfully. Then did make of Dashencoder and ran it as ./Dashencoder. But I found some issues in it. Got this log :

    Why is this error at the end ?
    and also one folder got created in my /opt/lampp/htdocs/tests_updates/sintel_300kbit.
    which has two types of files :
    27 files of .m4s extension
    1 file -sintelinit.mp4
    1 file- sintel_trailer_2k_480p24_300kbit.mp4 , which when played in vlc player played the video bt no audio ! &

    1 file- sintel_trailer_2k_480p24_300kbit.h264 which cannot be opened.

    No .mpd file was created.

    Also I want to know aft creating that .mpd file how will i be able to test it on my android client say media player.

    I am damn confused with all this happening. Please help.
