ffmpeg – capture screenshot from a video file
1 | ffmpeg -i /my_video_file_dir/video.flv -y -f image2 -ss 8 -sameq -t 0.001 -s 320*240 /image_dir/screenshot.jpg |
320*240 : image dimension is 320 pixels width and 240 pixels height
-ss 8 : screenshot will be taken at 8 second after video starts.
Big ups, this has helped me!
Wow, thanks!
How can I control the quality of the screenshot image?
Hi Snowcore,
“-sameq” means use the same quality of the source video.
I read the long “man ffmpeg”, I couldn’t find where to adjust the quality other than just “-sameq”
Hello,
Your code does the trick. Thanks. Does ffmpeg allows the user to take a snapshot of a movie directly by accessing a DVD disc or a video_ts folder in a similar way? If yes, how, please?
I’m using this, and is way more efficient:
ffmpeg -ss 00:20:00 -vframes 1 -i file.avi -y -f image2 out.png
I think the ss needs to go before the input so it does a fast skip.
Very Grand!!!
Hi, I have a question.
I want to capture the screenshot at 3.488 second for example
But it does not output screenshot by the above command
In my test, -ss 1 1.5 2 2.5 … works fine and others not
Can you explain why it happens and how can I capture screenshot at x.xxx time
huangyi,
Try ‘-ss 00:00:03.488′ instead
Hi, Thank you for suggestion
I try ‘-ss 00:00:03.488′ but it doesn’t work
And I changed the -t parameter from 0.001 to 0.08 and it can capture picture now. I find the 0.08 from ffmpeg output “frame=1 fps=0 q=0.0 Lsize=-0kB time=0.08 bitrate=-2.1kbits/s video:21kB audio:0kB global headers:0kB muxing overhead -100.100205%”
Do you know the usage of -t parameters when captures image from video and how I input the correct parameter.

Hi,I have a question!
There is a TS file named love.ts(about 1GB) on my SUSE machine, and I use this command to take a snapshot:
./ffmpeg -ss 00:00:18 -vframes 1 -i /home/sxp/love.ts -y -f image2 -s 900×900 sxp.jpg
So it takes a long long time!
But there is also a TS file named gdxw.ts (about 17MB), and I use the same command to take a snapshot. It takes a very short time.
What shall I do?
