ffmpeg thumbnails : Every 2 seconds, generated at 0, 1, 3, 5 seconds
30 janvier 2014, par Jim MillerI'm using ffmpeg to generate thumbnails from a piece of .mov video. I want to get thumbnails every two seconds, and so, copying almost directly from https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video, I'm doing :
ffmpeg -i test.mov -f image2 -vf fps=fps=1/2 thumb%04d.jpg
This works, and gives me thumbnails, but they correspond to the images from the video at 0, 1, 3, 5, ... seconds. I was expecting 0, 2, 4, 6, ... seconds ; I'm not sure why there's an initial one second gap between thumbnails before it settles into making them every two seconds.
Is there a way to get them to come out at 0, 2, 4, 6... seconds, or is this just "how it works" ? Thanks !

How to extract image frames from a bagfile ?
12 mars 2014, par LeyonceI am using ROS hydro on Ubuntu 12.04. After using the command "rosrun image_view extract_images _sec_per_frame :=0.01 image :=IMAGE_TOPIC_IN_BAGFILE" I'm having an error when executing"ffmpeg -r -b -i frame%04d.jpg .avi" The thing is I am not seeing the sequence of images after I play the bagfile.I ran "rosbag info" to obtain the topic in the bag file but when I run "rosrun rqtgraph rqtgraph" the /extract_image frame node is there all by itself.
When I follow the tutorials on http://wiki.ros.org/rosbag/Tutorials/... I get an error " [FATAL] [1394583654.335465840] : Error opening file : play".After replacing play by "--clock" everything seemed to go just fine but there are no frames*.jpg in /home/.ros hence the sequence of images are still missing. I feel like I'm lacking something.Can anyone help ?

6 octobre 2019, par toutou0091I installed ffmpeg using the instructions of the web site ffmpeg : http://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide, compilation works fine, they generates a file "ffmpeg_201207131721-git-1_amd64.deb " then, I excute
sudo dpkg-i ffmpeg_201207131721-git-1_amd64.deb
When I excute the command
ffmpeg -i -f toto.flv mp3-vn-acodec copy new_video.mp3
file "new_video. mp3" is well established. I would like to know what is the command "gdb" that I could use to find the file that have been consulted when i run the command
ffmpeg -i -f toto.flv mp3-vn-acodec copy new_video.mp3
Thank you in advance
