• make video from image file using ffmpeg

  4 août 2014, par Roylisto Putra Pradana

  i have 64 images sequence and i want to make a video using that images.

  you can download the images here

  i use ffmpeg in ubuntu.
  here’s my command

  ffmpeg -r 60 -f image2 -s 1360x768 -i "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/tmp/result%d.png" -vcodec libx264 -crf 20 "/home/roylisto/Documents/Tugas Akhir/JAva version/UAVSystem/UAVSystem/render/test.mp4"

  it works but only 39 images has generated to a video. My question is why ffmpeg not render all images in that folder into a video, what is my mistake and how to solve it ?

• configure : check $as first before using $gas as GNU as

  5 août 2014, par Janne Grunau

  configure : check $as first before using $gas as GNU as
  llvm’s integrated assembler supports the AArch64 asm on darwin since
  
  August 2014. So check $as first before using gas-preprocessor.pl via
  
  $gas. Makes the checks specific for that the architecture specific asm
  
  needs. PPC Altivec and AArch64 needs on ’:vararg’ for macro arguments.
  
  Arm needs in addition the ’.altmacro’ directive.
