• How can I split an RTSP stream so that I can both save it to files and apply a motion detection client ? (e.g. ffmpeg, motion)

  1er septembre 2022, par Pat Niemeyer

  I’ve been using "motion" successfully to read an rtsp stream and save motion triggered events.

  


  motion -c motion.conf # config file has the rtsp url and other params


  


  However I’d like to both save the full stream and analyze for motion in this way. I know that I can capture the stream to files with ffmpeg something like this :

  


  ffmpeg -i rtsp://mystream -vcodec copy -acodec copy -map 0 -f segment -segment_time 300 -segment_format mp4 "ffmpeg_capture-%03d.mp4"


  


  Is there is a way to split / duplicate the rtsp stream (perhaps using ffmpeg again) so that I can have both motion and ffmpeg processes looking at it simultaneously ? Alternately is there some option on motion that I’m missing that would automatically save both the raw video and the motion segments ?

  This makes the code a bit more readable.

• Decoding h.264 in node.js without ffmpeg and send it to front or save it in fs

  5 mars 2019, par JT.v26

  I’m doing the final project of a bootcamp.

  The project consists of controlling a drone (Tello) with a mobile phone. So for this project I’m using react native. In which I insert a node.js inside the application (Node.js for Mobile Apps React Native) since the drone creates a wifi and I lose internet access to connect to a remote server.

  All right so far, the drone has three udp ports enabled on the sdk to receive instructions, send status and send video.
  The video gives it to me in raw.

  I did a test on the computer, downloading ffmpeg and converting that data and I could effectively have the video retransmission.

  My questions are :

  Is there any way I can use the same technique on the mobile without needing ffmpeg ?

  Is there any way to import ffmpeg into android and communicate with nodejs ?

  Is there any other solution where I can use another node that doesn’t have to be on the phone ?

  Or you may even find some other solution to address this problem.

  Thank you very much in advance
