• vaapi_encode : Support configurable slices

  vaapi_encode : Support configurable slices
  This adds common code to query driver support and set appropriate
  
  address/size information for each slice.  It only supports rectangular
  
  slices for now, since that is the most common use-case.

• Set path while installing [duplicate]

  12 janvier 2021, par Education 4Fun

  My requirement is to set a path(C :/ffmpeg) while installing the software itself for my application(which I made)
  
A reference that it's possible(While installing python 3.8.0 we have check box by ticking it we can add the path of python automatically)
  
This is the main requirement which I wanna do with my application

  


  

  


  About My application :
  
My application is a simple video editing application that runs on cmd as it uses FFmpeg its path should be set only then the application will work
The application is coded in python and the GUI is made using pyqt5 The application runs on cmd like the commands and all here is a reference image for observation enter image description here

  


  

  


  So it's mandatory to add the path else FFmpeg will not recognize. If there is any way to do in building setup like how python can add the path as per user requirement refer to the image (1st image)

  


  About Files in C :/ffmpeg
Files in FFmpeg folder refer to image for that info

  


  

  


  Hope the query is a bit clear.
Thanks a lot

  


• Can I stream a static image feed into a video with Node.js ?

  5 juillet 2022, par Quentin Lamotte

  I want to create a small PoC where I can stream a static image source into a video. The idea behind that is that I have an (old) IP camera that only serves snapshots on an HTTP endpoint. When calling that endpoint, you get a static JPEG picture. Let's say, the URL I want to "convert" is : http://mycamera.local/live.jpg

  


  Now, I want to create a script using Node.js to quickly call that URL over and over in order to form some sort of video stream. I'm not an expert into media encoding and stuff, but I guess that the variable refresh rate induced by HTTP latency, the camera's FPS... would make it a bit trickier to pipe images into a video response ?

  


  I thought I'd go with Express and Axios to serve and query HTTP content. I've also read that FFmpeg could play a role in there. But, I am open to any suggestion. I could even switch languages if that's required. This question is so specific I think, that any response would do.

  


  A couple of requirements I cannot change :

  


  

  • The camera can only serve static pictures on a single endpoint.

  


  • I have no other protocol than HTTP on the camera.

  


  • I am not buying or modifying the existing hardware, even though I know there are very cheap units out there.

  


  • My server must serve a live video that could be streamed by VLC for instance.
