  • FFmpeg - Buffer queue overflow, dropping - when combining 2 videos and using concat, hstack and trim

    23 août 2018, par Mayank

    I am trying to merge two videos using concat and hstack but getting buffer overflow error resulting in the one of the video getting paused for few seconds.

    I tried adding fifo and h264 video codec as suggested on this forum but the issue persists.

    Can someone please let me know the issue in this command ? Many thanks in advance.

    ffmpeg -i 1_a.opus -i 2_a.opus -i 1_v.mp4 -i 2_v_bars.mp4 -filter_complex "[1:a]adelay=15720|15720[a1]; [0:a][a1]amix; [3:v]trim=0:15.81,geq=0:128:128,fifo [silence]; [silence][3:v]concat,fifo [3_v_silence]; [3_v_silence][2:v]hstack,fifo" -vcodec libx264 -strict experimental -y out_fifo_h264_2.mp4

  • FFMPEG for aws s3 bucket signed url not working in node js

    21 août 2018, par ahmed sharief

    I am trying to create thumbnails from an amazon s3 bucket signed url. I am able to generate thumbnails when i run the command in terminal

    ffmpeg -ss 00:00:02 -i "https://test-s3-bucket.s3.ap-south-1.amazonaws.com/user_gallery_assets/5b6936069ac2bf0602085367/gallery/images/5b7be08527641dee8c1f8134.mp4?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=xxxxxxxxx%2F20180821%2Fap-south-1%2Fs3%2Faws4_request&X-Amz-Date=20180821T095101Z&X-Amz-Expires=900&X-Amz-Signature=d7f81f4eed3d6c87c04dc1b0ad06beeb946afa33d417585f57fad72aeadb3ac0&X-Amz-SignedHeaders=host" -vframes 1 -q:v 2 -f image2 output.jpg

    I am running the above command in terminal and its working fine but when i try to implement the same in node js its showing "no such file or directory error". Though i am encoding the url with double quotes then also its showign same error. Here is my node js code....

    function uploadThumbNailForVideo(obj,url, thumb_url){
       return new Promise((resolve, reject) => resolve(url))
       .then((url) => awsHelper.getImage(url))
       .then((result) => {

           var resUrl = "\""+result+"\"";

           var args = [
               '-i', resUrl,
               '-ss', '00:00:02',
               '-vframes', '1',
               '-f','image2',
               'output.jpg'
           ]
           //console.log(args)
           var ffmpeg = require('child_process').spawn('ffmpeg', args);

           ffmpeg.on('error', function (err) {
               console.log(err);
           });

           ffmpeg.on('close', function (code) {

           });

           ffmpeg.stderr.on('data', function (data) {
               var tData = data.toString('utf8');
               var a = tData.split('\n');
               console.log("A",a);
           });

           ffmpeg.stdout.on('data', function (data) {
