• AFTER PHP-FFMpeg not converting (error with ffmpeg)

  15 juin 2018, par Magurean Dan Sergiu

  I have installed ffmpeg server side with all the dependencies, updated it. And then installed PHP-FFMpeg with Composer. Tested that ffmpeg is instaled with a ssh conexion.

  root@host [/opt/ffmpeg]# ffmpeg

  $format = new FFMpeg\Format\Video\X264();
  
  $format->on('progress', function ($video, $format, $percentage) {

  $video

  ?>

  Error displayed :

  Unknown encoder 'libx264'

  My question is what to do next ? I have wasted 3 days to make this work and this is the furthest I have come. How can I test if libx264 is installed corectly ? And if it is not installed corectly how cand I reinstal or make it work ?

  After a few modifications

  I have used an already installed ffmpeg, and removed a few commands (that were by default the same) and this time I used only the command line.

  11 juillet, par Zac Chan

  I am a novice at ffmpeg and have recently taken over a code base built by a previous engineer. The FFmpeg code is on an app engine that will edit the videos when they are uploaded.

  


  This code generated a title animation that will later be used as an overlay.

  


  exports.generateTitleAnimation = function(metadata, destPath, options = {}) {
const peeqLogoPath = "/app/assets/peeq-logo.png";
const whiteBarMovPath = "/app/assets/whiteBar.mov";
const titleFontPath = "/app/assets/Sofia-Pro-Black.otf";
const dateStrFontPath = "/app/assets/Sofia-Pro-Medium.otf";
const outputDuration = 5.52;
const src01 = "color=c=white:s=1920x1080:duration=" + outputDuration;
const src02 = "color=c=white@0.0:s=1920x1080:r=120:duration=" + outputDuration;

var dateStrXOffset = "(92";
var filterComplexStr = "[1]";

if (metadata.title) {
    const title = metadata.title.toUpperCase();
    filterComplexStr += "drawtext=fontfile=" + titleFontPath + ":text='" + title + "':x='floor(92*(min((t-1.75)^29,0)+max((t-3.75)^29,0)+1))':y=622+30+2:fontsize=70:fontcolor=black:ft_load_flags=render,";
}
if (metadata.subTitle) {
    const subTitle = metadata.subTitle.toUpperCase();
    filterComplexStr += "drawtext=fontfile=" + titleFontPath + ":text='" + subTitle + "':x='floor(92*(min((t-2.0)^29,0.0)+max((t-3.8)^29,0.0)+1.0))':y=622+184-20-60+9:fontsize=46:fontcolor=black:ft_load_flags=render,";

    dateStrXOffset += "+30*" + (subTitle.length + 1);
}
if (metadata.dateStr) {
    filterComplexStr += "drawtext=fontfile=" + dateStrFontPath + ":text='" + metadata.dateStr + "':x='floor(" + dateStrXOffset + ")*(min((t-2.0)^29,0.0)+max((t-3.8)^29,0.0)+1.0))':y=622+184-20-60+9:fontsize=46:fontcolor=black:ft_load_flags=render,";
}
console.log("generateTitleAnimation generating")
filterComplexStr += "split=10[t01][t02][t03][t04][t05][t06][t07][t08][t09][t10];[t02]setpts=PTS+0.0166/TB[d02];[t03]setpts=PTS+0.033/TB[d03];[t04]setpts=PTS+0.05/TB[d04];[t05]setpts=PTS+0.0666/TB[d05];[t06]setpts=PTS+0.083/TB[d06];[t07]setpts=PTS+0.1/TB[d07];[t08]setpts=PTS+0.1166/TB[d08];[t09]setpts=PTS+0.133/TB[d09];[t10]setpts=PTS+0.15/TB[d10];[d10][d09]blend=average,[d08]blend=darken,[d07]blend=average,[d06]blend=darken,[d05]blend=average,[d04]blend=darken,[d03]blend= average,[d02]blend=darken,[t01]blend=average,colorkey=white:0.2:0.0,perspective=y1=W*0.176327:y3=H+W*0.176327[text01];[2][3]overlay=x=(W-w)*0.5:y=(H-h)*0.5:enable='between(t,0,3.0)'[logo01];[logo01][text01]overlay[outv]";

var args = ["-y", "-f", "lavfi", "-i", src01, "-f", "lavfi", "-i", src02, "-i", whiteBarMovPath, "-i", peeqLogoPath, "-filter_complex", filterComplexStr, "-vcodec", "qtrle", "-crf:v", "28", "-codec:a", "aac", "-ac", "2", "-ar", "44100", "-ab", "128k", "-map", "[outv]", destPath];

//console.log("args", args);
return childProcess.spawn('ffmpeg', args).then((ffResult) => {
    return destPath;
}, (err) => {
    //console.error(new Error("generateTitleAnimation:" + err));
    console.error(err);
    return Promise.reject(err);
});};


  


  destPath is a .mov file

  


  Up till a few days ago, the backend started throwing up this error

  However, this error only occurs on the app engine. Running nom test on my Mac generates the title perfectly.

  


• FFmpeg error : Output file is empty, nothing was encoded

  25 mai 2018, par Morteza M

  I am using the following command ffmpeg command and execute it in Python. It used to work for at least a month finely. However, its two days it stopped working and generates different errors. The most important one is "Output file is empty, nothing was encoded"

  PS : I checked the connectivity to Camera and is healthy. I am able to see the Camera output on my screen using its software.

  The Command :

  ffmpeg -i rtsp ://username:pass@ip_add:port/videoMain -b 1920k -f image2 -r fps -strftime 1 %Y-%m-%d_%H-%M-%S.jpg

  PS : fps is taken from input. I mainly used 1 for that.

  I would be gratfful if anyone can help with this. Thank you.
