  • How to generate a variable framerate video with sync'd audio from a bunch of images and an audio file ?

    28 avril 2014, par Michael Kohout

    I’ve got a series of images captured using a motion activated camera-right now, I’m doing a bit of processing on them and each image is stored as a PNM/PBM file but I can easily convert them back to PNGs. I have a unix timestamp of when each were first created. I’ve also got an audio file (where I know the starting time), recorded over the same period.

    Is there any way I can construct a lossless video that should be playable from VLC from these images ? Ideally, I’d like the audio to sync.

  • Error when using path with consecutive dots in concat file of ffmpeg

    22 décembre 2020, par Kajuna

    A user of my software encountered a crash when trying to concatenate files that were in a directory with triple dots in its name. I can also reproduce the problem with double dots. Lines in the concat file look something like :

    


    


    file 'C :\a...b\video.MP4'

    


    


    ffmpeg crashes with

    


    


    [concat @ 0000025dbde52e00] Impossible to open 'b\video.MP4'

    


    


    So it seems like consecutive dots break the path in some way. I could not find info on them being a special character.

    


    I tried escaping the dots in different ways, and the one I expected to work was

    


    


    file 'C :\a'\.\.\.'b\video.MP4'

    


    


    But made no progress.

    


    What am I missing ?

    


    Edit : I wonder if it's interpreting the dots as part of a relative path

    


    Thank you

    


  • FFmpeg leaves green pixels in a simple video [closed]

    19 septembre 2024, par Patola

    I use this command to remove the green screen and overlay another video as background. However, green screen removal leaves green pixels all around a stick figure carton character. My video is a cartoon so there are no lighting issues. Is there a way to improve this behavior ?

    


    ffmpeg -y -i looped.mp4 -i green.mp4 -filter_complex "amix;[1:v]chromakey=0x00FF00:0.18:0.01 [ckout];[0:v][ckout]overlay=eof_action=pass[out]" -map [out] output.mp4
