Prevent output in error log when ffmpeg job is initiated via PHP's shell_exec()

19 janvier 2016, par Jake

I’m getting the entire output of the ffmpeg command printed to my server’s error.log — but as far as I can tell, the jobs complete successfully with no error.

Is there any way to suppress the output ? I have seen people append stuff like >/dev/null 2>/dev/null & to their command, however that forces the command to return immediately and the job runs in the background. Unfortunately, I need the job to run in the foreground, because I need to do stuff with the output once the job is done.

Here’s the command I am running...

shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');

Here’s the output I am seeing...

Final Rendered Video is Sped Up Compared to Animation Played in Processing

15 janvier 2016, par Nightlife

Recently I made an Audio Visualizer in Processing. From there I wanted to render the animation created in Processing into a mp4 file. I am on a windows computer, and am using ffmpeg to convert my TIF files produced in Processing into mp4.

When I do this I am able to render the images into an mp4 file, but when I playback this file the animation is sped up compared to the animation when I play it on Processing. Because of this the animation does not sync with the audio when I combine the mp4 file and audio on a video editing program.

When I set my frame rate to 25 and have the limit on the number of frames to be 250 and render it into a mp4 file it is 10 seconds long like it should be, but it contains more than 10 seconds of the animation when compared to the animation played directly in Processing.

I have no idea why this is so any help will be much appreciated.

My Processing code :

import ddf.minim.*;

import ddf.minim.analysis.*;



Minim minim;

AudioPlayer player;

PImage img;

FFT fft;



void setup() {

  size(728, 546);



  minim = new Minim(this);



  // this loads mysong.wav from the data folder as a stream with a internal buffer of size 1024

  player = minim.loadFile("new_years_good.mp3");

  fft = new FFT(player.bufferSize(), player.sampleRate());

  player.play();

  img= loadImage("cat-in-shades-.jpg");

  frameRate(25);

}



void draw() {





  image(img, 0, 0);

  //tint(0, 100, 150);

  stroke(255);



  strokeWeight(4);

  float a = 0;



  float angle = (2*PI) / 200;





  fft.forward(player.mix);





  for(int i=0; i &lt; player.bufferSize() - 1; i++) {



   //player.mix.get(i) is a value between [-1,1]



    float x = 250 + cos(a) * (20 * player.mix.get(i) + 100);

    float x2 = 540 + cos(a) * (20 * player.mix.get(i) + 100);    



    float y = 230 + sin(a) * (20 * player.mix.get(i) + 100);

    float y2 = 240 + sin(a) * (20 * player.mix.get(i) + 100);





    float xFinal = 250 + cos(a+angle) * (20 * player.mix.get(i+1) + 100);

    float x2Final = 540 + cos(a+angle) * (20 * player.mix.get(i+1) + 100);





    float yFinal = 230 + sin(a+angle) * (20 * player.mix.get(i+1) + 100);    

    float y2Final = 240 + sin(a+angle) * (20 * player.mix.get(i+1) + 100);    





    line(x,y,xFinal,yFinal);

    line(x2,y2,x2Final,y2Final);

    a += angle;  







  }

  noStroke();  

  fill(255, 0, 0, 128);

  for(int i = 0; i &lt; 250; i++)

  {

    float b = fft.getBand(i);

    float yAxis = random(-b, b) + 480;

    float xAxis = i*3;

    ellipse(xAxis, yAxis, b, b);

  }

  saveFrame("frame-####.tif");

  if(frameCount>250)

    {

      noLoop();

      stop();

    }



}



void stop() {

  player.close();

  minim.stop();



  super.stop();

}

ffmpeg video conversion from webm to mp4 is adding lag to the video

21 janvier 2016, par Hemant Kumar

Hi I am trying to convert video from .webm extension to .mp4 extension and it is adding lags to the video, also not showing me the full video.

I am using following video conversion command.

"ffmpeg -i {$input} -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ".fix_video_orientation($input)."' -threads 0 -ab 64k -s {$resolution}  -movflags faststart -metadata:s:v:0 rotate=0 {$output}";

"fix_video_orientation" function is given below. It rotate the resulting video if video while recording is rotated to certain angle.

function fix_video_orientation($input){



$return= ", transpose=1 ";



$dd= exec("ffprobe -of json -show_streams  {$input}   | grep rotate");



if(!empty($dd)){



$dd=explode(":",$dd);

$rotate=str_replace(",","",str_replace('"',"",$dd[1]));



if($rotate=="90")return $return;



else if ($rotate=="180") return ", transpose=2,transpose=2 ";



else if($rotate == "270") return ", transpose=2 ";

}

Currently above script is supporting "flv","avi","mp4","mkv","mpg","wmv","asf","webm","mov","3gp","3gpp" extensions, also the script is supporting the resulting .mp4 file to play on all browsers and devices.

For query :

ffmpeg -i <server path="path">/g9zyy2qg54qp1l5spo2-mergedFile.webm -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 <server path="path">/g9zyy2qg54qp1l5spo2-mergedFile5.mp4
