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 ?

Facing delay in mic audio while using ffmpeg with h264_nvenc encoder [closed]
30 avril 2023, par Aniket BoseI am trying to capture my windows10 desktop with desktop duplication api and on-gpu D3D11 textures, in the form of ffmpeg D3D11VA frames @60 fps. Required command is given here. On top of that I am trying to also intercept my mic audio. For that I am using this command,


ffmpeg -init_hw_device d3d11va -filter_complex ddagrab=framerate=60 -f dshow -i audio="Microphone (High Definition Audio Device)" -c:v h264_nvenc -rc vbr -cq 24 -qmin 24 -qmax 24 -profile:v main -b:v 0K output.mp4


After the desktop capture process when I am watching output.mp4 I am facing an audio delay. More Precisely my mic audio is coming after 28/29 video frames. ie. (28/60)*1000 = 466 ms delay in audio.


I tried to capture @30fps but no improvement. Now I am getting 14 frames delay ie. (14/30)*1000 = 466 ms delay in audio.


After some research I came to know about keyframe intervals. at default h264_nvenc uses 200 sec keyframe interval. So i tried to lower that with the -g option of h264_nvenc encoder. No improvement here too.


One possible solution could be to delay my video using -itsoffset option. These stack overflow and superuser solutions only work with pre-recorded videos,




In ffmpeg, how to delay only the audio of a .mp4 video without converting the audio ?


But I am capturing and encoding on the go (ie. at same time).


I am a novice at video editing and ffmpeg. I am using latest release build from gyan.dev.
