Livestream not reaching AWS endpoint
13 août 2024, par NoobAmII'm trying to stream my live video into Amazon IVS and I don't see it on the live channels.


Is it possible I have a mistake in my FFMPEG configuration ?
I'm expecting to see this in my playback url or on the console screen for playback but I see nothing at the moment.


As I understand it, shouldn't I see some kind of playback in the live channels if a stream is being sent that channel ?


async ivsStreamingService(payload: any): Promise<void> {
 const injestServer = '***.global-contribute.live-video.net:443/app/';
 const streamKey = 'sk_us-east-1_*****';
 const ffmpeg = spawn('ffmpeg', [
 '-re',
 '-i', '-',
 '-r', '30',
 '-c:v', 'libx264',
 '-pix_fmt', 'yuv420p',
 '-profile:v', 'main',
 '-preset', 'veryfast',
 '-x264opts', 'nal-hrd=cbr:no-scenecut',
 '-minrate', '3000k',
 '-maxrate', '3000k',
 '-g', '60',
 '-c:a', 'aac',
 '-b:a', '160k',
 '-ac', '2',
 '-ar', '44100',
 '-f', 'flv',
 `rtmps://${ingestServer}${streamKey}`
 ]);
 
 ffmpeg.stdin.write(payload, (err) => {
 console.log(payload)
 if (err) console.error('Error writing payload to FFmpeg stdin:', err);
 });
 
 ffmpeg.on('close', (code) => {
 console.log(`FFmpeg process exited with code ${code}`);
 });
 
 ffmpeg.stdin.on('error', (err) => {
 console.error('Error writing to FFmpeg stdin:', err);
 });
 
 ffmpeg.stderr.on('data', (data) => {
 console.error(`FFmpeg error: ${data}`);
 });
 }
</void>



I'm not quite sure why it wouldn't receive the stream, as it would appear everything is correct.

24kHz audio file problem : unsupported bitrate 64000
28 novembre 2018, par R. VaitI use alexa audio tags a lot. I know that now audio tags support 24kHz audio files so tried converting my audio files from 16kHz. I used the provided command in the docs to do so :
ffmpeg -i -ac 2 -codec:a libmp3lame -b:a 48k -ar 24000But when I try to play this file, I get an invalid response error, saying :
Error: The audio is of an unsupported bitrate 64000. By looking into file details I clearly see, that bitrate is 48kbps and sample rate is 24kHz. I don’t see any value where it would say 64 or anything close to it.If I encode my file back to 16kHz it plays fine again.
It seems that there is a problem with this command, because if I encode my files using audacity, they work with 24kHz. I still would prefer to use ffmpeg, because I need to encode a lot of files.
I am asking, not about file format, format is correct. I need files in 24kHz sample rate and that is what causes issues. I saw another question about similar problem and others having the discussion there about sample rates, but no one was able to encode file to be 24kHz using ffmpeg.
Did anyone had any luck on encoding files to 24kHz using ffmpeg ?

Transcode video with php ffmpeg library
27 juin 2019, par devI need to upload video in 3 formate/resolution as 360p, 480p, 720p.
After some research i got to know that some paid service are there like Amazone Elastic Transcoder . But i want to do with open source so i found FFMPEG.
Also i want to upload video on Amazon s3 after transcode and video are in big size like video may contain 1GB size.
I got php library for FFMPEG Library Link
I have installed ffmpeg and it successfully generate new video. But i cannot figure out that how can i generate different formate/resolution as 360p, 480p, 720p.
My sample Code is
error_reporting(E_ALL);
ini_set('display_errors', 1);
require 'vendor/autoload.php';
//$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open('assets/small.mp4');
$video
->filters()
->resize(new FFMpeg\Coordinate\Dimension(320, 240))
->synchronize();
$video
->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(2))
->save('assets/frame.jpg');
$format = new FFMpeg\Format\Video\X264();
$format->setAudioCodec("libmp3lame");
$video->save($format, 'assets/new.mp4');Can anyone suggest me any way that how can i achieve this ??
