• Combine multiple images to form a strip of images ffmpeg

  10 décembre 2019, par phuong do

  I wish to combine multiple images into a single strip of images, using FFMPEG.

  I have been trying to search this thing on google, but unable to find anything useful. All links take me to places where multiple images are combined to give a video output.

  Assuming that all the files are of the same width and height, how can I join them to get a single strip of images. Can anybody help me ?

• How do I make a C# win form program that breaks a video down to frames, then put those frames back together to make a video ?

  30 juillet 2015, par Atom Scott

  First, I’m fairly new to C sharp so I’m looking for a thorough and easy to understand answer.

  How do I make a C# win form program that breaks a video down to frames, then puts those frames back together to make a video ?
  I also want to be able to select which frames to extract by setting an interval time. For example, extract frames that are one second apart.
  Is this possible, I have done some research but I don’t understand how to use the codes displayed on the following websites.

  Supposedly code to breakdown video into frames. However I do not know where to put it. Do I make it the event for a button or something. From my own research I am guessing this uses ffmpeg. But I’m not exactly sure how to use ffmpeg, I have tried downloading Aforge, and use Aforge.Video.ffmpeg. But I’m stuck there.

  Code for making a video from images, it looked promising so i tried to copy and paste it visual studio. However the line using BytescoutImageToVideoLib ; has an error asking me whether I am missing a reference. What reference am I missing ?

  I also noticed that there was a page on code project for something similar to this, but the downloadable demo project didn’t work at all. I didnt see the point in spending time on something where the end product is broken.

  Any help is greatly appreciated.

  dds : Write the palette in the native endian form
  This fixes the palette on big endian, broken (or, differing from
  
  little endian) since 57214b2f7.
