FFmpeg not decreasing
19 avril 2018, par DavidI need
ffmpeg
to transform a video stream into images and reduce their size only if they don’t fit in a 1000x1000 box.My issue is that if the image is smaller, ffmpeg increases the size of the image to 1000 in width or height, whereas I don’t want small images to be upscaled. The
force_original_aspect_ratio=decrease
does not seem to work here. Any ideas why ?Here is my shell command :
ffmpeg -i 'rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov' -r 5 -vf scale=w=1000:h=1000:force_original_aspect_ratio=decrease -f image2 -qscale:v 1 ./output_%01d.jpg

Is it possible to have a progress bar without a loop ?
26 novembre 2017, par KurtI am using FFmpeg to do some video editing. I would like to have a progress bar but there is not a loop in my code. I’ve tried tqdm and putting my code in a loop with a range of 1 but that will only display the progress bar at 100%. Maybe there is another way to accomplish this ? This is the code I’m using :
import subprocess
inmovie=mymovie.mp4
speed=str(4.0)
outmovie=newmovie.mp4
print('Converting file.......')
subprocess.call('ffmpeg -i '+inmovie+' -filter:v "setpts= '+speed+' *PTS" '+outmovie, shell=True)
print('Conversion done') -
Is there a way of using ffmpeg in c# app ?
6 mai 2015, par randomuser1I’m using the ffmpeg.org and when I run
ffmpeg -y -f vfwcap -r 25 -i 0 out.mp4
in command line I can grab the video from my webcam and write it to theout.mp4
file. However, I can’t see that stream anywhere. I thought about writing some simple wrapper in c# that is built on ffmpeg functionality, so far I found post mentioned on Stack before, but there’s nothing about displaying the data live (instead of saving it into the file). Does anyone have any experience with it ? Can I for example ’draw’ the received data from webcam on a picture box or on some other component ?
Thanks !
