  • USB webcam streaming in ARM board (i.MX6)

    5 septembre 2017, par Titus

    I want to streaming the camera via NETWORK. I have connected the USB webcam to i.MX6 board and want to stream in Ubuntu14.04/16.04 via network.

    Incidentally, I have installed the gstreamer and ffmpeg tools for this in i.MX6 board.

    Also I am able to stream USB webcam within Ubuntu14.04 PC using the following ffmpeg commands. But it’s also not working if I use ffplay in other Ubuntu16.04 and I am not sure why (both are same ffmpeg versions).

    ffmpeg -f v4l2 -i /dev/video0 -preset ultrafast -vcodec libx264 -tune zerolatency -b 900k -f mpegts udp://192.168.0.37:1234

    Finally I want to stream with different ARM boards. Am also not able to build ffplay command. Same issue with raspberry pi too. I am doing something wrong or misunderstood something here ?

  • ffmpeg : simple RTMP streaming over LAN

    30 mars 2013, par sajad

    I am trying to launch up a rtmp transcoder server using ffmpeg ; that receives udp MPEG-TS streams as input, transcodes it ; and generates an rtmp output to a URL, that can be accessed by users to receive and play the rtmp stream. All these are expected to be performed in a LAN and the output be accessed by all users.

    1) First I don't know where the URL should point to. Is it enought to specify the IP of the system and some optional port ? Is it neccessary that a program should be listening on that port ?

    2) How I can play the stream on the URL ?

    I use a linux ubuntu machine whith IP=10.1.1.229 and I want to transcode multicast stream on this URL : udp://@224.10.1.1:2001.

    here is the command used to transcode input stream and generate rtmp url "rtmp ://10.1.1.229:2020".

    ffmpeg -y -f mpegts -i "udp://@224.10.1.1:2001" -re -vcodec libx264 -maxrate 700k -r 25 -s 640x360 -deinterlace -acodec libfaac -ab 64k -ac 1 -ar 44100 -f flv "rtmp://10.1.1.229:2020"

    and here is the command by which I am trying to play rtmp stream :

    ffplay rtmp://10.1.1.229:2020

    Any guidance would be helpfull. Thank you.
