  • Should a long Running video processing task to be done client side or server side

    27 avril 2021, par Ritwiz Sinha

    I was creating an application in react for uploading video and using a REST API to send that to the server and store in S3. I also wanted the simple audio version of the video for some other tasks and I am confused as to what might be the better way :

    &#xA;

      &#xA;
    1. Creating audio file on the fly when it is needed using node-ffmpeg package and not store it anywhere

      2. &#xA;

    2. Start converting the video file to audio on the browser client only, and posting that to the server for storage along with the video.

      3. &#xA;

    3. Just post the video to the server and use queue system for creating a new task for video conversion to audio and then save that to the S3 storage.&#xA;The second method seems to be saving some compute power on the server but it might be a problem if the video upload completes, audio conversion is still going on and the client disconnects.&#xA;Would appreciate some help, thanks.

  • Change bitrate of USB camera

    12 décembre 2018, par Nick Saw

    I use ELP USB camera with h264-codec output.

    Ffmpeg-command to take the video stream :

    ffmpeg -i /dev/video1 -c:v copy output.ts

    As result I have a video with 4Mb bitrate - this value is too high for my task.

    There is the same situation when I use GSTreamer :

    gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-h264,width=1280,height=720,framerate=30/1 ! mpegtsmux ! filesink location=output.ts

    I know that it’s possible to change the bitrate if we decode h264 the stream firstly and then encode it to h264 again. This operation requires too much CPU-power of my NanoPI device.

    The main question is :
    Is it possible to change a USB-camera’s bitrate without decoding ?

    Thanks in advance !
