I'd like to know how could I add an
.assformatted subtitle and render it in the FFME control withvsfilterorvsfiltermod. -
If I modified the
.asssubtitle file, could FFME automatically using the modified subtitle ? -

FFMPEG on AWS Lambda Only outputs half a second of video when converting video from mobile safari
18 août 2023, par user1825257I am running FFMPEG on AWS Lambda using nodejs and fluent-ffmpeg. I am able to convert videos recorded on most devices / browsers, but when I attempt to convert videos recorded on Mobile Safari, the length of the output video is 1/2 a second regardless of the input length.


My Typescript code is :


import * as ffmpeg from 'fluent-ffmpeg';
 public static StandardizeVideoFormat(
 inputSignedUrl: string,
 filename: string,
 ): Promise<string> {
 const localFilePath = `/tmp/${Date.now()}_${filename}.mp4`;
 
 return new Promise((resolve, reject) => {
 ffmpeg(inputSignedUrl)
 .outputOptions([
 '-crf',
 '18',
 '-vcodec',
 'libx264',
 '-codec:a',
 'aac',
 '-preset',
 'medium',
 ])
 .output(localFilePath)
 .on('start', function (commandLine) {
 console.log('Spawned Ffmpeg with command: ' + commandLine);
 })
 .on('error', function (err) {
 reject(err);
 })
 .on('progress', function (progress) {
 console.log('progress', progress);
 })
 .on('end', function () {
 resolve(localFilePath);
 })
 .run();
 });
 }
</string>

Using FFprobe, The metadata of the input file is :

Any ideas on why the output of my command on this file always results in a 0.5 second long output ?
