Video produced from images only plays in VLC but no other players

Within my folder with bunch of 13MP bmp images named 0001.bmp, 0002.bmp,... I run the following commands from command line.

Crop images to 4K

ffmpeg -i %4d.bmp -vf "crop=3840:2160:184:240" croped%4d.bmp

Scale images

ffmpeg -i croped%4d.bmp -vf scale=1920:1080 scaled%4d.bmp

Compress images to video

ffmpeg -r 25 -i scaled%4d.bmp -c:v libx264 -b:v 25000k -minrate 25000k -r 25 -s 1920x1080 -c:v libx264 -qp 20 -preset medium output.mp4

But the produced video can only be played in VLC, every other player fails.

Can anyone with more experience in ffmpeg suggest where I'm making a mistake?

This is the ffmpeg console output after the last command:

Solution 1:

When you convert from BMP, JPG or PNG files, ffmpeg will try to preserve as much detail as possible and encode the video with the best matching color space. Your resulting file uses the yuv444p non-subsampled colorspace. JPGs use yuv422p. Many players cannot show video in this format, such as Windows Media Player, QuickTime and others.

To get a video supported in non-FFmpeg-based players, use this command, with the most important thing being the -pix_fmt yuv420p option.

Note that I removed your other options for the sake of brevity.

ffmpeg … -i scaled%4d.bmp -c:v libx264 … -pix_fmt yuv420p output.mp4

By the way, your ffmpeg is rather old. Please update to a new version. Recent versions warn you of the color space being YUV 4:4:4 and that incompatible players might not show the video or even crash.
