I had to make a few changes mainly to support the meta data extration otherwise I would have imported the project directly. The core of this project is based on the FFmpeg.AutoGen wrapper by Ruslan-B on GitHub ( ).
NET library to map ffpmeg DLLs and use them to extract frame images from a multimedia file and an application to easily create thumbnail sheets using the library.
NET and after many disappointing projects which I coulnd't get to work I found FFmpeg.AutoGen which worked from the start with the example. So I started some research for possibilities to pinvoke FFmpeg DLLs directly in. But that method didn't satisfy me because it's everything but a clean way. I've already published the article " Another FFmpeg.exe C# Wrapper" using FFmpeg.exe via commandline parameters to extract frame images. For longer videos you will need to use a higher number ( %08d.png).įfmpeg -i input.mp4 -pix_fmt rgba64be output_%04d.pngįfmpeg -i input.mp4 -pix_fmt rgb24 output_%04d.pngįfmpeg -i input.mp4 -pix_fmt rgb48be output_%04d.pngįfmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgba output_%04d.tiffįfmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgba64le output_%04d.tiffįfmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgb24 output_%04d.tiffįfmpeg -i input.mp4 -compression_algo lzw -pix_fmt rgb48le output_%04d.Download FFmpegWorker (Source only).zip Introduction Using the above example the output files will be called output_0001.png, output_0002.png, output_0002.png and so on. %04d specifies the position of the characters representing a sequential number in each file name matched by the pattern.
Replace input.mp4 with the name of your video and output_ with the name your output image files. Use this command to extract the video to a png image sequence:įfmpeg -i input.mp4 -pix_fmt rgba output_%04d.png.Open a terminal and navigate to the folder containing the video.FFmpeg provides a convenient command-line solution for converting video to images.
