  • Concat different video file types with different fps and resolutions using FFmpeg

    10 juillet 2018, par 1234567

    This is the command I am using :

    {"-y", "-i", file1.toString(), "-i", file2.toString(), "-strict", "experimental", "-filter_complex",
                   "[0:v]scale=480x640,setsar=1:1[v0];[1:v]scale=480x640,setsar=1:1[v1];[v0][0:a][v1][1:a] concat=n=2:v=1:a=1",
                   "-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "480x640", "-vcodec", "libx264","-crf","27","-q","4","-preset", "ultrafast", rootPath + "/output.mp4"};

    When file types are similar, in my case mp4, and with same fps 30 and same resolution, 720 x 980, they do merge properly. But when I try different file types, say AVI, 3gp, mp4, then all with different fps and resolution and the AVI file with no audio, I get following error :

    FFmpeg creates empty palette, for better quality GIF conversion

    I have referred to

    https://ffmpeg.org/ffmpeg-filters.html#palettegen-1

    https://superuser.com/a/556031/724432

    but it creates an empty pallete file

    I am trying it on android

    the command used is

    {"-y", "-i", j, "-ss", 10, "-t",3,"-vf","fps=15,scale=300:-1:flags=lanczos,palettegen", palette};

    and the error that is shown is

  • Create a video with timestamp from multiple images with "picture taken date/time" in the meta data with ffmpeg or similar ?

    16 mars 2018, par m4D_guY

    I have two time lapse videos with a rate of 1 fps. The camera took 1 Image every minute. Unfortunately it was missed to set the camera to burn/print on every image the time and date. I am trying to burn the time and date afterwards into the video.

    I decoded with ffmpeg the two .avi files into  7000 single images each and wrote a R script that renamed the files into their "creation" date (the time and date the pictures where taken). Then i used exiftoolto write those information "into" the file, into their exif data or meta data or whatever this is called.

    The final images in the folder are looking like this :

    2018-03-12 17_36_40.png

    2018-03-12 17_35_40.png

    2018-03-12 17_34_40.png

    ...

    Is it possible to create a Video from these images again with ffmpeg or similiar with a "timestamp" in the video so you can see while watching a time and date stamp in the video ?
