• Online timelapse creation with ffmpeg

  27 mai 2016, par Michael

  I would like to create a timelapse using a command line tool like ffmpeg. The usual way is to prepare a series of images first. In my case it is not possible, because discrete images would take too much space, and there is nearly no difference between subsequent images so they compress extremely well as a video.

  So I’m looking for a way to create a video file, keep it opened and then just append successive images to it without intermediate files.

  This file does indeed no longer exist.

  


  Our app heavily relies on ffmpeg_kit_flutter_full_gpl. What should we do now.

  


  Please help me, everyone

  


  I also tried pulling the source code locally, but it still reported the same error

  


• (FFmpeg) VP9 Vaapi encoding to a .mp4 or .webm container from given official ffmpeg example

  13 mai 2021, par User800222

  I'm trying to implement vp9 hardware acceleration encoding process. I followed ffmpeg offical github's example (Here -> vaapi_encode.c).

  



  But given example only save a .yuv file to .h264 file, I would like to save the frames to either .mp4 or .webm container. And having the ability to control the quality, and etc.

  



  I'm not reading frames from a file, I'm collecting frames from a live feed. When having full 5 secs of frames from the live feed, encode those frames using vp9_vaapi to a 5 secs .mp4 file.

  



  I'm able to save all the 5 secs frames from my live feed to a .mp4 or .webm file, but they couldn't be played correctly (more precisely : keep loading, and I open).

  



  The result from the official site's example :

  



  

  



  The cpu encoded vp9 .mp4 file result :

  



  

  



  Edit :
