• How to convert video to .ico files sequence using ffmpeg ?

  3 août 2019, par marto55555

  I cannot successfully convert an .mp4 video to a sequence of .ico files.

  I tried using the same command as for converting to a sequence of .jpg/.png/.bmp files :

  ffmpeg -i video.mp4 %05d.png

  Unfortunately, when I try with :

  ffmpeg -i video.mp4 %05d.ico

  I get only a single .ico file and the following output error :

  Output #0, ico, to '%05d.ico':

  Conversion failed!

  I have also tried using the image2 muxer through -f image2. This time, the sequence will be generated. However, the images will not be actual ICO files, but JPEGs ending in .ico instead.

• FFmpeg Convert to JPEG works in VLC but not in Mac Preview ?

  24 juillet 2019, par Evan Keeton

  I’m trying to convert a PNG image to a JPEG image using ffmpeg. As far as I can tell, it’s working fine, but it doesn’t display properly in Mac Preview.

  I’m running the following :

  $ ffmpeg -i foo.png foo.jpg

  And it produces the following output :

  When I open foo.jpg in most applications, such as VLC or Google Chrome, I get exactly what I expected : an image that looks exactly the same as foo.png, the input.

  
  

  However, this is what is displayed in the Finder preview, and the same this is displayed when I open up the file in "Preview."

  

   I wonder if this has something to do with the deprecated pixel format used, make sure you did set range correctly error, but I’m not sure, especially since the image is fine, the problem seems to be elsewhere. 

  It seems the deprecated pixel format error is not the issue (that’s an internal thing), so I guess I just need to specify pixel formats properly.

• FFmpeg is dropping a frame when converting MP4 to image sequence

  24 juillet 2019, par Phillip Dodson

  I have an MP4 file that’s encoded at 12fps that I’m trying to convert to an image sequence using FFmpeg. The issue is that there is one frame missing. I’ve used the solutions here to confirm that the number of frames are 195 but when I run the following ffmpeg -i video.mp4 frames_%04d.png, I only get 194 PNGs. I’ve tried using the -r 12 and -framerate 12 flags but they do not change the output.

  I’ve also run the MP4 through Adobe Media Encoder to create an image sequence and that produces 195 frames. Any thoughts on to why I’m losing a frame ?
