  • FFmpeg produces empty file sometimes

    30 avril 2024, par Matan Malka

    I am currently using ffmpeg and attempting to convert multiple PNG files to MP4 video.

    


    My command is :

    


    ffmpeg -y -r 10 -i "videos-reporter/MC4xMzg3NDI1MTY2Mjg1MTk=/b8a7ee17d8ecfd199edbc5edc9691698/screenshots/%04d.png" -vcodec libx264 -pix_fmt yuv420p -vf "scale=1200:trunc(ow/a/2)*2","setpts=3.0*PTS" "videos-reporter/MC4xMzg3NDI1MTY2Mjg1MTk=/b8a7ee17d8ecfd199edbc5edc9691698/video.mp4"


    


    Sometimes, I'm unsure when the ffmpeg creates a 1kb empty video file that cannot be played.

  • FFmpeg converting image sequence to video results in blank video [closed]

    11 juillet 2019, par Brandon Durham

    I’ve got a series of 361 .png files that I’m trying to convert to video, and for whatever reason the resulting video is just black. Here is the FFmpeg code I’m using :

    ffmpeg -f image2 -i "FeatureTour_%05d.png" -r 30 -vcodec libx264 -b:v 9600k "FeatureTour.mp4"

    The files are formatted correctly (FeatureTour_00001.png) and no errors are thrown. It just results in a 160kb mp4 files that’s black.

    Any idea what I’m doing wrong ?

    EDIT

    Here is my output after using the above code :
