  • Azure Media service live streaming using raspberry pi 2

    29 juillet 2015, par emy virk

    I have tried to stream a video from my raspberry pi 2 using a webcam using the tutorial here http://gtrifonov.com/2015/07/02/streaming-live-video-from-raspberrypi-to-azure-media-services/.
    Using ffmpeg, I am running this in Ubuntu mate terminal :

    ffmpeg -framerate 30 -r 30 -s 640×480 -i /dev/video0 -vcodec libx264 -preset ultrafast -acodec libfaac -ab 48k -b:v 500k -maxrate 500k -bufsize 500k -r 30 -g 60 -keyint_min 60 -sc_threshold 0 -f flv $INGESTURI

    Now, to see the video is streaming I am using PLAY PREVIEW URL from the azure portal. It works, interrupted, at a very fast speed for about 5 second and than it stops with an error
    After that I try to play the video again and I can see the one that was streaming before the error and than it breaks again.
    From the Ubuntu mate I can tell the streaming is working fine : connection established and I can see the frames being sent.

    fps=7.9 q=28 bitrate = 500 kbits

    any idea why this is happening ?

  • Dynamically Extending FFMPEG Playlist for Continuous Video Streaming

    3 août 2023, par dumbQuestions

    I am trying to create a seamless FFMPEG playlist so I can add new videos without interrupting the stream. Currently, I'm using the following command :

    


    ffmpeg -re -f concat -safe 0 -i playlist.txt -c copy -f flv "${INPUT_URL}"

    


    The initial playlist works fine, but when I try to append new files to it, the streaming stops and the newly added files don't seem to affect the output.

    


    I've tried manually editing the playlist.txt file and adding new video files to it while streaming, but it seems like FFMPEG doesn't automatically detect the changes and continues the streaming seamlessly. I also attempted using the -concat option, but it didn't work as expected.

    


    Is there a proper way to dynamically extend the FFMPEG playlist while maintaining continuous video streaming, or a way to continuously stream new clips one after the other without interruptions ? Any insights or suggestions on how to achieve this would be greatly appreciated. Thanks in advance !

    


  • A delay on streaming the video in some ANDROID device

    15 juillet 2017, par Alwin Varghese

    i have an application used for streaming and recording videos from an external device and i have a
    customized tablet with the following specifications :

    1) Android OS 4.2

    2) Processor : Freescale iMX6 Quad

    On running the application on this tablet, there is a delay in streaming the video.

    i.e for example : The video is being streamed to the application and we move our hand over the camera, the hand appears inside application after some delay, say 2seconds.App is working fine with other devices.My assumption is that cause of lower hardware specification.

    My android application is using ffmpeg library for streaming the video.
    The video received from the external camera is MPEG encoded
    The Bosch tablet decoder is h.254

    is there any way to stream without delay on above mentioned device ?
