  • Convert mp3 -> Video with static image ( ffmpeg/libav & BASH )

    17 avril 2022, par Max

    Some years ago I used the following bash script to get a video out of mp3's and one image (so the image in the video was freezed over the length of the mp3), which worked out fine.

    



    i=0;
for file in *.mp3; 
do 
i=$((i+1));
ffmpeg -loop 1 -shortest -y -i image.jpg -i $file -acodec copy -vcodec libx264 $file.flv;
done


    



    Now I wanted to use this again for doing the same.

    



    Problem :

    



    It does not stop converting at the end of the mp3. Means the current mp3 file eg. has a length of 3 minutes and the script converts until forever or I stop it, so the length of the flv is much bigger than 3 minutes.

    



    (ffmpeg is installed, but with libav the same happens)

    



    Output :

  • capture DV video and audio with ffmpeg and dshow

    18 novembre 2016, par andrixnet

    Trying to capture video and audio from a DV camera, using ffmpeg, I got into a problem.
    Before anything, I first tried to see (and hear) with ffplay.

    I can use VLC with "Capture device" as input, selecting "Microsoft DV Camera and VCR" as video device and leaving "Default" as audio device and I get both video and audio.

    With ffmpeg I get only video stream, no audio.

    C:\>ffplay -hide_banner -f dshow -i video="Microsoft DV Camera and VCR"

    I don’t know how to tell ffmpeg the equivalent of "Default" audio device as VLC recognizes it.

    Device options show there are 2 pins for video device (DV device has both video and audio) but how can I tell ffmpeg such that it captures both video and audio ?
