• A good Library for video processing

  24 février 2015, par user3397178

  I am going to work on videos. Different kind of processing, detection and recognition can be involved. I already know about some of the famous libraries such as OpenCV, ffmpeg, moviepy. The language programming is not a big deal. I am really thankful if you introduce me a fast, efficient and convenient library which you have already used for video processing and object detection from video.

  Any suggestion would be appreciated.

• How to get frames from rtsp in c#

  27 février 2023, par JOJODA

  I want to play multiple videos for face recognition at the same time.

  


  I'm having a lot of problems trying to read frames from rtsp for processing.

  


  Is there a good way to do this ?

  


  I started using emgucv, opencv, vlc and found that they all have high delay.

  


  Then use FFmpeg.autogen, the delay is reduced, but it does not support multithreading.

  


• Improved thumbnail extraction from videos

  21 janvier 2014, par Tommy Ng

  I have been using FFmpeg to find the middle frame of a h264 video file, and extract the jpg thumbnail for use on a streaming portal. This is done automatically for each uploaded video.

  Sometimes the frame happens to be a black frame or just semantically bad i.e. a background or blurry shot which doesn't relate well to the video content.

  I wonder if I can use openCV or some other method/library to programmatically find better thumbnails through facial recognition or frame analysis.
