  • Using ffmpeg to overlay black line or add border to two side by side videos

    14 février 2020, par user3135427

    I am using the following to generate a video that is side by side.

    ffmpeg -i left.mp4 -i right.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS, pad=iw*2:ih[bg]; [1:v]setpts=PTS-STARTPTS[fg]; [bg][fg]overlay=w" -y final.mp4

    It looks like this.

    http://www.mo-de.net/d/partnerAcrobatics.mp4

    I would like to place a vertical black line on top right in the middle or add a black border to the video on the left. If I add a border to the left video I would like to maintain the original sum dimension of the original videos. This solution would require subtracting the border width from the left videos width. I will take either solution.

    Thanks

  • FPV-Camera Input in Black and White / losses Color on conversion with FFMPEG [closed]

    22 décembre 2023, par LyffLyff

    so we're working on our end-of-school project and it's an FPV-Drone with an Analogue Camera on it. Plan is to send the video feed to a Raspberry Pi running an RTMP-Server from where a Phone-Application can view the live Video of the camera.

    


    To convert this analogue Data from the camera we use a USB2.0 Grabber (this one).

    


    To create the RTMP Stream from the converted USB-Input we use FFMPEG with the following command :

    


    


    fmpeg -f v4l2 -input_format yuyv422 -i /dev/video0 -c:v libx264 -crf 20 -preset ultrafast -b:v 2000k -fflags nobuffer -rtmp_live live -f flv rtmp ://192.168.8.107:554/live/stream

    


    


    It works fine, but the main problems at the moment are :

    


      

    • the video is in Black and White
B&W Image Stream

      • 


    • the stream has a delay of 10-20s depending on the network

      • 


    


    When I'm using the official Software provided by the Reseller I had the same problem, but as soon as it set PAL/BDGHI in the Settings the colour was shown correctly :

    


    Settings and Color Image in official software

    


    the video is in Black and White

    


    Does anyone know what settings there are to correctly decode the feed from the Camera and send the video with the colour over RTMP ? I don't know if this is the right place to ask this question, but I'm running out of ideas and every single decoder I have tried apart from the ones I'm currently using does not work.

    


    Any help is greatly appreciated :)
