FFMPEG : Extracting 20 images from a video of variable length
12 novembre 2013, par VapireI've browsed the internet for this very intensively, but I didn't find what I needed, only variations of it which are not quite the thing I want to use.
I've got several videos in different lengths and I want to extract 20 images out of every video from start to the end, to show the broadest impression of the video.
So one video is 16m 47s long => 1007s in total => I have to make one snapshot of the video every 50 seconds.
So I figured using the -r switch of ffmpeg with the value of 0.019860973 (eq 20/1007) but ffmpeg tells me that the framerate is too small for it...
The only way I figured out to do it would be to write a script which calls ffmpeg with a manipulated -ss switch and using -vframes 1 but this is quite slow and a little bit off for me since ffmpegs numerates the images itself...
Any suggestions or directions ?
Thanks,

5 décembre 2015, par user176455If I don’t make a mistake, Safari currently need MP4 (H.264/AAC) video encoded for the HTML5
<video></video>
element.So I tried to convert a video to this format with
ffmpeg
. However when I enter the shell commandffmpeg -i video.flv video.mp4
, the returned error is :Seems stream 0 codec frame rate
differs from container frame rate :

for output stream #0.1An AAC codec is required but I’m quite newbie with ubuntu and I dont really now how to fix this problem. I’m using Ubuntu 9.10 Karmik Koala (for amd64).
Thank you very much. :)
