• Downloading and Uploading FFmpeg [closed]

  24 décembre 2011, par user705339

  I have a Windows OS for development, and a Linux server. I downloaded ffmpeg on my Windows, configured everything, and uploaded the application. The video conversion didn't work. After extensive hours figuring out the culprit, I realized that I downloaded the ffmpeg for Windows, and need to download the Linux version. That seemed harder than downloading the Windows version. I have scoured the net, and have come up with squat

  So, my 2 questions are :

  1. Is there an easy way to download/install the linux version of ffmpeg ? OR
  2. Is there an easier way to install it straight on the server ?

  If it matters, I also have a Linux OS development, but found it hard to install ffmpeg on it anyway.

  Update : After trying apt-get install ffmpeg on my Ubuntu Linux OS, it says it has already been installed. How do I locate what folder it's located ?

• Code library for image processing [on hold]

  1er septembre 2014, par user3928079

  Dear Stack Overflow Users,

  I am looking to create my programming portfolio as a graduate of Kennesaw State University by July 2015, when I graduate. I want to create at least 3 cross platform programs related to video or animation. In the package there will be a program for playing video and music files, a program for converting video and music files, and either a program upscaling video and image files or a program that helps animators create animation like Flipbook Pro. Since Java is cross platform, and Java is the language I’m more comfortable with, I’ll develop the software in Java, unless of course Python is cross platform as well. May you please recommend me some image processing libraries that will help me accomplish the development of these types of software programs. For the upscaling program, an upscaling algorithm from BenVista called S-Spline Max is needed, especially since I want to preserve the detail of the image, because in upscaling, you are unable to gain new information from the original information. What are some good image processing libraries I can use. I know of OpenCV, but what do a lot of programs use, high profile or low profile, like Adobe Premiere Pro or Davinci Resolve. FFMPEG is a good video library, but can it easily accomplish what I need ? What are some others that can help me in my 11 month long quest ?

  Regards,

  Jordan White

• ffmpeg : sliding overlay for filter comparison

  8 octobre 2020, par cduguet

  I am trying to get the effect demonstrated in this video : https://www.youtube.com/watch?v=xrMZSLb_gPs

  


  Most of the sliding overlay solutions I've seen are for a sliding fixed image, but not for a progressive crop of each part of the video.

  


  I've tried doing :

  


  ffmpeg -i video1.mp4 -i video2.mp4 \
 -filter_complex "[0]crop='min(iw*(1+n)/100,iw)':ih:0:0[left];[1]crop='max((1-n/100)*iw,1)':ih:1-'max((1-n/100)*iw,1)':0[right];[left][right]hstack[out]" -map '[out]' -y out.mp4


  


  But it still does not work. Is there a way ?

  


  Thank you !
