Live stream doesn't seem to be passed to AWS correctly
12 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 sendDataToIvs(channelArn: string, payload: any): Promise<void> {
 const injestServer = '***.global-contribute.live-video.net';
 const streamKey = 'sk_us-east-1_*****';
 
 const ffmpeg = spawn('ffmpeg', [
 '-re', // Read input at native frame rate
 '-i', '-', // Input from stdin (live stream data)
 '-r', '30', // Frame rate
 '-c:v', 'libx264', // Video codec - H.264
 '-pix_fmt', 'yuv420p', // Pixel format
 '-profile:v', 'main', // H.264 profile
 '-preset', 'veryfast', // Encoder quality setting
 '-x264opts', 'nal-hrd=cbr:no-scenecut', // Additional x264 options
 '-minrate', '3000', // Minimum bitrate
 '-maxrate', '3000', // Maximum bitrate
 '-g', '60', // GOP size
 '-c:a', 'aac', // Audio codec
 '-b:a', '160k', // Audio bitrate
 '-ac', '2', // Audio channels
 '-ar', '44100', // Audio sample rate
 '-f', 'flv', // Output format
 `rtmps://${injestServer}:443/app/${streamKey}` // Output destination
 ]);
 
 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}`);

flv live stream audio delay with ffmpeg refresh rate option
15 janvier 2018, par albert200000I have problem with live http flv stream. I’m using the following command and it works great except for the audio. Audio has delay that increasing over time. I can fix the this by removing refresh rate option on the output (-r 30) but then stream latency goes higher for about half second.
ffmpeg -f v4l2 -threads 0 -video_size 672X420 -i /dev/video1 -f alsa -thread_queue_size 512 -i hw:1,0 -c:a aac -ar 44100 -b:a 128k -c:v libx264 -s 672x420 -r 30 -g 60 -preset superfast -tune zerolatency -strict -2 -f flv rtmp://localhost/live/primaryCan someone explain why this happening and what possible fixes are ?
On the client I’m using Chrome with flv.js library.
On the server Node-Media-Server.
