-vframes is deprecated, use -frames:v instead

@NickeManarin Oops, sorry, I misread that you just wanted a PNG instead of JPG version of what's shown in this answer. To output entire file as PNG to stdout, use this: ffmpeg -i video.mp4 -c:v png -f image2pipe - (notice the bare hyphen at the end). I believe -f rawvideo - might work instead of image2pipe also.

@NickeManarin Yes.. ffmpeg -ss 01:23:45 -i video.mp4 -c:v png -frames:v 1 image.jpg. Notice that I also put the -ss "seek" option before the input file on the command line, as others have recommended.

| Dec 19, 2014 at 20:07 | comment | added | SirDarius | try using the -ss option before -i since it will skip the decoding part of the pipeline. This might speedup the process. | |
| Dec 19, 2014 at 20:02 | comment | added | Peter Bengtsson | Yeah, this approach is super slow. See peterbe.com/plog/fastest-way-to-take-screencaps-out-of-videos | |
