    I have an invalid format file (showing .mp3) , I want to convert it into a different format

    enter image description here

    


    And I want to convert it into exactly like this .wav format

    


    enter image description here

    


    If I am using simply ffmpeg -i input.mp3 out.wav it's not giving exact same .wav as the second file. What config I should use in FFmpeg to convert first audio same like second audio ?

    


  • Use FFmpeg to rotate the video based on it’s metadata ? Why Android put the wrong metadata ?

    27 août 2014, par Mauro Valvano

    Hi have a website where the user upload a video.
    For my website i have also the Android application.
    The website create a thumbnail of each uploaded video (from browser or Android).

    The problem is that for normal videos its all OK, but for android my videos are rotated of 90°.

    I think that android have a bug, because when i see with FFmpeg the video’s metadata, for a normal recorded video i got a rotate=90 value, and for a 90° rotated video i don’t have nothing in the metadata (and the thumbnail is correct).

    Why ?

    This is an image of a normal recorded video (with the phone in portrait mode).

    FFmpeg showing the rotate metadata in a normal recorded video

    Anyways, i have the metadata in the video, can i create it’s thumbnail based on it’s metadata’s rotate value without extracting the metadata and then use ffmpeg to rotate the video on this value ?

    Thank you in advance.

  • FFmpeg YouTube live streaming automatically stopped after some time (6- 9 min) RTMP node js

    30 juin 2020, par Avneesh Singh

    I am developing a feature where I am capturing the desktop screen and live streaming on YouTube by using the FFmpeg module. The streaming is working fine but the problem is it stopped automatically after some time like 6-9 min and YouTube is showing "no data" receiving.
Below I attached the code.
const process = spawn(pathToFfmpeg,["-probesize", "10M", "-f", "gdigrab", "-i", "desktop", "-framerate", "30", "-f", "dshow", "-i", "audio= Microphone (2 - USB audio device)", "-filter_complex", "amix=inputs=1", "-preset", "fast", "-g", "60", "-tune", "zerolatency", "-c:v", "libx264", "-crf", "10", "-pix_fmt", "yuv420p", "-map", "0", "-maxrate", "1M", "-bufsize", "2M", "-vsync", "vfr", "-acodec", "pcm_s16le", "-b:v", "4500k", "-b:a", "128k", "-f", "flv", "-", ], 
stdio : "pipe"

) ;

    


    after that, I am encoding it by using FFmpeg path.
let proc = ffmpeg(stream).size('1920x1080').videoBitrate('4500k').videoCodec('libx264').fps(30).audioBitrate('128k').audioCodec('aac').audioFrequency(22050).audioChannels(2).toFormat('flv').on('end', () => console.log('file has been converted succesfully') ;).on('error', (err) => console.log('an error happened : ' + err) ;).save(publish) ;
