  FFmpeg lavfutils.h seems to be missing - Collin Newest 'ffmpeg' Questions - Stack Overflow
  The lavfutils.h file is missing from the include folder where the ffmpeg library was put. I installed the ffmpeg library to load an image in c++. I installed it using ./vcpkg ffmpeg. The ff_load_image function is in lavfutils.h, but that file is missing from the ffmpeg_x64-windows folder where vcpkg put the rest of the library. Has the way you load images changed? Or have I installed ffmpeg incorrectly?

  Google Lato Font Display discrepancies between platforms/software [closed] - CRAIG Newest 'ffmpeg' Questions - Stack Overflow
  Using Google's Lato font with 400 weight, is giving me some inconsistent results between Photoshop/Web on MacOS and Linux Imagemagick & Linux ffmpeg.

  Slow frame copy from d3d11va to CPU memory in LibAV - Igor Newest 'ffmpeg' Questions - Stack Overflow
  I'm using LibAV to decode video (H.264) using dxva2 or d3d11va hardware decoder. I then copy the decoded video frame from the GPU memory to system memory by calling av_hwframe_transfer_data(). I noticed that when using the modern d3d11va hardware decoder, the CPU load is twice as much as when using the old dxva2 hardware decoder. I checked with LibAV 6.1 and with the old version V4.4 - the same result.

  How to save last 30 seconds of video in py - Mateus Coelho Newest 'ffmpeg' Questions - Stack Overflow
  I want the last 30 seconds to be recorded every time I click enter and sent to the cloud. for example, if I click at 00:10:30, I want a video that records from 00:10:00 to 00:10:30 and if I click in sequence at 00:10:32, I need another different video that in its content is recorded from 00:10:02 to 00:10:32. I think I have a problem where I will always end up recovering from the same buffer in the last 30 seconds. Is there any approach so that whenever I click enter I retrieve a unique video? Is my current approach the best for the problem? Or should I use something else? import (...)
