  I'm trying to record video from my ip camera stream with ffmpeg in command line

  


  fmpeg -rtsp_transport tcp \
>  -i rtsp://192.168.0.250/stream1 \
>  -c copy \
>  -map 0 \
>  -f segment \
>  -segment_time 60 \
>  -segment_format mp4 \
>  "/home/video/stream-%010d.mp4"


  


  and got the next output :

  Tried some different options like -c:v libx265 or -c:v libx264 but it does not works the output is a little different. But the main error is the same :

  


  Could not find tag for codec none in stream #1, codec not currently supported in container

  UPD : Tried the next command :

  


   ffmpeg -rtsp_transport tcp \
 -i rtsp://192.168.0.250/stream1 \
 -c copy \
 -map 0 \
 -f segment \
 -segment_time 60 \
 -segment_format avi \

  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 Prabaghan

  I'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 of socket.io. BUT MY PROBLEM IS, I can't pipe this byte array to the ffmpeg spawn process. I don't know how to properly pipe this data to the ffmpeg. Once it done, all my problem will be solved.

  


  On the other side, I have node-media-server as 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.
