FFmpeg can't access file in Dropbox on Ubuntu 12.04
30 juin 2015, par afterglowleeI have installed FFmpeg on Ubuntu 12.04. When I use
ffmpeg -i
command to check some video file online, it works :ffmpeg -i http://techslides.com/demos/sample-videos/small.mp4
However, when I check a public file hosted in my Dropbox it gives ’No such file or directory error’ :
ffmpeg -i https://dl.dropboxusercontent.com/u/51617581/bigbuck.webm
and the error is :
https://dl.dropboxusercontent.com/u/51617581/bigbuck.webm : No such
file or directoryand here is the version info of the ffmpeg installation :
ffmpeg version 0.8.17-4:0.8.17-0ubuntu0.12.04.1, Copyright (c)
2000-2014 the Libav developers built on Mar 16 2015 13:26:50 with
gcc 4.6.3I have also tried both files on my Mac 10.10 laptop, and both of them work fine. Could anyone suggest where is the problem ? Many thanks.

How can I compress and create mp4 video file from batch of images on hard disk using ffmpeg ?
29 juin 2015, par Brubaker HaimIn my directory I copied ffmpeg.exe to the same directory where all the images are.
All images are bitmaps.Then in the command prompt windows I typed :
ffmpeg -f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v mpeg4 -r out.mp4
But I get error that there is no a directory name :
\.\pipe\mytestpipe
So I removed it and typed the same line without the pipe part.
ffmpeg -f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i -map 0 -c:v mpeg4 -r out.mp4
Now there is no a directory name -map
So I moved the
-map 0
ffmpeg -f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i -c:v mpeg4 -r out.mp4
Now I’m getting error :
-c:v : Protocol not found
I used this line with the pipe in my c# program as arguments to ffmpeg using
ProcessStartInfo
but now I don’t want to use pipes only in the command prompt to type it and compress and create mp4 video file.Edit I tried this now :
ffmpeg -framerate 1/5 -i screenshot%06d.bmp -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4
And what I get is some errors :
E:\screenshots>ffmpeg -framerate 1/5 -i screenshot%06d.bmp -c:v libx264 -r 30 -p
ix_fmt yuv420p out.mp4

orscreenshot000003.bmp
orscreenshot000122.bmp
it will work fine and create the video file. But when i’m doing this for all images i’m getting all the errors :ffmpeg -framerate 1/5 -i screenshot%06d.bmp -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4
here is the results when i did onscreenshot000002.bmp
and it worked fine.When i’m doing it on a single image file it’s working fine like
screenshot000002.bmp
but when doing it on all the imagesscreenshot%06d.bmp
it’s giving me all the errors i mentioned above.
