make video from image file using ffmpeg
4 août 2014, par Roylisto Putra Pradanai have 64 images sequence and i want to make a video using that images.
you can download the images here
i use ffmpeg in ubuntu.
here’s my commandffmpeg -r 60 -f image2 -s 1360x768 -i "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/tmp/result%d.png" -vcodec libx264 -crf 20 "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/render/test.mp4"
it works but only 39 images has generated to a video. My question is why ffmpeg not render all images in that folder into a video, what is my mistake and how to solve it ?

ffmpeg only processes first image
8 septembre 2020, par Michael PriceI have a directory of .png images (I had previously tried .jpg until I read somewhere ffmpeg prefers .png).


The images share a file numbering format cof000.png - cof358.png.


I want to convert those images into a moving picture format. MPG or MP4 will be fine.


The command I have tried is


ffmpeg.exe -framerate 25 -i cof%03d.png -r 6 output.mp4



I adapted the command from this post, here :


https://stackoverflow.com/questions/53778503/ffmpeg-video-slideshow-only-takes-first-image



Even after trying numerous different permutations of the command the final file only has the first image in it. I am using windows.


What ffmpeg command do I need to use on Windows to compile all 180 image files into a single moving image ?


Here is the output from using the command :

Popen.write - operation on closed file | images to video using FFmpeg
10 juin 2014, par f.rodriguesI’m trying to create a video file from images from my webcam(using SimpleCV), the images are converted to PIL format and then tostring() [rawformat]
I’m using python subprocess and Popen to create the video using the FFmpeg.
I can pipe the one image to the FFmpeg and make a video out of it
But when I try to do a bunch of them I get a error :ValueError: I/O operation on closed file
here’s my code.
import subprocess as sp
from SimpleCV import *
from Image import Image
FFMPEG_BIN = "ffmpeg.exe"
img = Camera().getImage().toRGB()
command = [FFMPEG_BIN, '-y', # (optional) overwrite output file if it exists
'-f', 'rawvideo', '-vcodec', 'rawvideo', '-s', '%sx%s'%(img.width,img.height), # size of one frame
'-pix_fmt', 'rgb24', '-r', '24', # frames per second
'-i', '-', # The imput comes from a pipe
'-an', # Tells FFMPEG not to expect any audio
'-vcodec', 'libx264rgb',
'my_output_videofile.mp4']
pipe = sp.Popen(command, stdin=sp.PIPE)#, stderr=sp.PIPE)
for n in xrange(10):
img = Camera().getImage().toRGB().getPIL().tostring()
pipe.stdin.write(img)
pipe.terminate()It’s wierd because the pipe.terminate() is in the end of the code, and it should close the file right away.
