  • Replace part of a video (without replacing the audio) in ffmpeg [closed]

    13 février 2021, par Real Noob

    I have a video file that is divided into three different sections. I want to replace the middle part of this video with another clip. However, I still want to keep the audio of the original video. Can I do that in ffmpeg ?

    


    Here are my requirements :

    


      

    1. Original Video is 60 seconds long.

      2. 


    2. The part I want to replace is from 25 to 45 seconds.

      3. 


    3. I want to keep the original audio from 25 to 45 seconds and just replace the visual part with some other clip.

      4. 


    4. The generated video will also be 60 seconds long. However, it will have the new video from 25 to 45 seconds.

      5. 


    


    Thanks.

    


  • Stream part of the screen on linux

    1er juin 2014, par Boris Brodski

    How can I stream part of my screen using ffmpeg (avconv) on Linux ?

    I can record part of my screen :

    ffmpeg -f alsa -ac 1 -i pulse -acodec pcm_s16le -f x11grab -r 24 -s 100x200 -i :0.0+20,30 ...

    But trying to stream it adding

    -f rtp rtp://127.0.0.1:1234

    doesn’t work. ffmpeg starts to stream, but ffplay complains

    $ ffplay rtp://127.0.0.1:1234
    
[rtp @ 0xaf8026a0] Unable to receive RTP payload type 96 without an SDP file describing it

  • How to show part of a frame from a 4k IP cam

    15 avril 2022, par BrP

    I'm working with andoroid.js framework to create a simple app that will show the video that is streamed from some IP cam.

    


    I want to add the ability for the user to see only a part of the full video frame that have a resolution of 4k, so for example, if the user want to see the upper left corner of the frame, he can see it like the image is magnified. I'm not sure if this is possible.

    


    Is there any ffmpeg or any way to accomplish this with a library for node ? Can I include ffmpeg with node_modules when I build my app ?
