[FFmpeg-user] Problem with ffmpeg frames

[Stefan Kruse]

Hi, i try to use ffmpeg to make thumbnails from images. I try it on server
with:

 

shell_exec( 'ffmpeg -i '.$inputVideoPath.' -ss 00:00:00.00 -f image2
-vframes 1 '.$outputVideoImage );

 

But then comes the error:

 

Ff_frame_encoder_init failed

 

What does this mean.

 

Thanks for helping.

Stefan
