FFmpeg streaming stuck few minutes after start [closed]
19 février, par josue ramirezSorry for my english ! :D


I'm trying to make a live video stream from my webcam with ffmpeg using Node.


I get the images or frames from ffmpeg via pipe1 on the stdout event and send them via a socket-io client to my angular app to play the stream.


So far the stream starts fine and my angular app can play it fine, but after a certain time (8 minutes or so) ffmpeg stops sending data and the stream in my angular app stops and if I want to start the webcam again it's not possible anymore because it's apparently occupied by another process. I've been trying to figure out what's going on and what I've noticed is that the ffmpeg process just stops and the process is no longer visible with the
topcommand (ubuntu), but the child process in node still shows a ffmpeg process as if it were a zombie process.

I've tried running ffmpeg from the terminal to save an mp4 file with the stream and in that case there is no problem, the recording doesn't stop even using pipe1. Only when I run ffmpeg from my Node app, the error occurs.


Does anyone have any idea what could be going on ?


This command is the one that is executed to send the data through pipe1 both from node and from the terminal but it only stops in Node


ffmpeg -f v4l2 -input_format mjpeg -video_size 800x600 -i /dev/video0 -q:v 4 -f image2pipe pipe1


The same thing happens when saving an mp4 video only in Node it fails


ffmpeg -f v4l2 -input_format mjpeg -video_size 800x600 -i /dev/video0 -q:v 4 video.mp4


This is my function that starts the streaming


export const startCamera = () => {
 logger.info('Starting camera ', cameraName);

 const inputFormat = process.platform === 'win32' ? 'dshow' : 'v4l2';

 const ffmpegArgs = [
 '-f', inputFormat, // Formato de entrada según la plataforma
 ];

 if (process.platform === 'linux') {
 ffmpegArgs.push(
 '-input_format', 'mjpeg', // Especificar el formato antes de video_size
 '-video_size', '800x600', // Tamaño de la imagen
 );
 }
 
 ffmpegArgs.push(
 '-i', cameraName, // Dispositivo de entrada
 '-vf', 'fps=15', // Fotogramas por segundo
 '-q:v', '10', // Calidad de video
 '-f', 'image2pipe', // Formato de salida
 'pipe:1' // Salida por stdout
 );

 try {
 logger.info('FFmpeg command: ffmpeg', ffmpegArgs.join(' '));
 ffmpeg = spawn('ffmpeg', ffmpegArgs);
 let cameraOpen = false;
 // Enviar los datos del fotograma a través del WebSocket
 ffmpeg.stdout.on('data', (chunk) => {
 logger.debug(`Sending chunk of ${chunk.length} bytes`);
 if (!cameraOpen) {
 cameraOpen = true;
 serialConnection.connect();
 logger.info('Camera started!!');
 }

 if (streamWS.isActive()) {
 streamWS.send(chunk);
 }
 });
 // Manejo de errores
 ffmpeg.stderr.on('error', (data) => {
 logger.error('FFmpeg Error:', data.toString());
 });

 ffmpeg.on('close', async () => {
 logger.info('Camera closed....', cameraName);
 if (!cameraOpen) {
 await commandWS.send(
 {
 command: COMMANDS.START_STREAM,
 isError: true,
 response: `Error al intentar iniciar la camara ${cameraName}, verificar que la camara se encuentre bien conectada.`,
 },
 COMMANDS_EVENTS.ROBOT_RESPONSE
 );
 }
 cameraOpen = false;
 await serialConnection.close();
 stopCamera();
 await streamWS.disconnectWS();
 });
 } catch (e) {
 logger.error('Error tryng to start the camera...', e);
 }
