Librairies et logiciels spécifiques aux médias
10 décembre 2010, parPour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.

Tried some different options like
-c:v libx265or-c:v libx264but it does not works the output is a little different. But the main error is the same :

UPD : Tried the next command :


ffmpeg -rtsp_transport tcp \

 -c copy \
 -map 0 \
 -f segment \
 -segment_time 60 \

It started to record video but with errors :

NodeJS : Fail to write byte array input from webcam to ffmpeg spawn process
23 mai 2024, par Thanesh PrabaghanI'm using NodeJS server to display an HTML page which has webcam option. Once user visited to my NodeJS server, it will serve html page. User can allow webcam option and see webcam view on the page.


In the backend, I send webcam stream (byte array) using
socket.io. I receive byte array successfully in backend with the help ofsocket.io. BUT MY PROBLEM IS, I can't pipe this byte array to theffmpegspawn process. I don't know how to properly pipe this data to theffmpeg. Once it done, all my problem will be solved.

On the other side, I have
node-media-serveras RTMP server to publish this stream to VLC player and other devices. Kindly help me to complete this task. I will attach all my code to this question. Kindly run this in your environment and answer the question.
