  • Directly response video to the client for download when ffmpeg cutting the video

    7 mars 2023, par web disiner

    I am bulding a web application using Node.js with Express framework. That simply cut the video and send to the client browser as a response for download. For cutting a video i use FFmpeg tool.
all things working fine but ffmpeg cutted video save to working directory.

    


    Below is my code..

    


    const child_process= require("child_process")

const cutting =async()=>{
    ffmpeg = child_process.spawn('ffmpeg', [

        "-i", /video.mp4,
         "-ss", "00:02:20",
         "-to","00:02:50",
         "-c:v", "copy", 
         "-c:a", "copy", 
         "output3.mp4"






    ])
    ffmpeg.stderr.on('data', function(data) {
            console.log('ffmpeg stderr data = '+data );
      });

}


    


    This is image of working directory

    


    Now i want when **ffmpeg cutting the video it directly send chunks of video to the client for download **without saving it in working directory or server where my code is hosted.

    


    How can i do this ? which approch will useful for this ?
Anyone help me. much appreciated
Thanks

    


  • How to include both audios when overlay video on video with FFMPEG

    28 septembre 2021, par Yogas

    I have 2 inputs : video.mp4 (with audio) and notif.mov (with audio). I want to overlay notif.mov on video.mp4. I tried this code :

    


    ffmpeg -y -i video.mp4  -i "notif.mov" -filter_complex "[0:v][1:v]overlay=0:0" output.mp4


    


    Both videos playing simultaneously, but sound missing from second input (notif.mov).

    


  • Cropping black bars in video with ffmpeg on ubuntu changes video size

    9 décembre 2013, par pramod

    I have a source video size that's 720x576 with black rectangles on the top and bottom.

    I want to remove the black rectangles and set the output video size to 640x352.

    I tried -vf cropdetect and the value it gave was 640:192:0:80.

    However, putting that same value in crop=<parameter></parameter> changes the output video size.

    How can I fix this ?

    E.g. :

    ffmpeg -i all_the_best_test.mpg -s 640x352 -deinterlace -b 500k -minrate 500k \
    
-maxrate 500k -aspect 1.82 -force_fps -vcodec libx264 -me_method 10 \
    
-vf crop=640:192:0:80 -r 25 -acodec libfaac -ac 2 -ar 44100 -ab 96k -subq 6 \
    
-vpre medium /vod/Movies/final/allthebest-crop-2.mp4
