• React-Native - Path to local Files

  31 mars 2023, par iSaBo

  my question is about react-native 0.60+ and about local files.

  



  My App has the followed folder structure :

  



  

  • App.js

  


  • android

  


  • ios

  


  • node_modules

  


  • src


    

    • components

    


    • views

    


    • assets

    


    • images


      

      • myImage.png

      


    


  


  



  Now, i want to get the path from myImage.png.
I want to add an Watermark to a Video. The Watermark to add, is the myImage.png. For that issue i use the ffmpeg-Library.

  



  But how can i access to these files ? What is the Path of these files ?
i have tried it with React-Native-Filesystem (RNFS), but with no solutions.

  



  Every time a get : Directory or File not exists

  



  FFMPEG Cmd :

  



  const ffmpegWatermarkCommand = '-i '
+ RNFS.ExternalStorageDirectoryPath+ '/videos/myVideo.mp4 '
+ "-i [Path to Local Watermark]/myImage.jpg '
+ '-filter_complex "overlay=10:10" '
+ RNFS.ExternalStorageDirectoryPath + '/videos/outVideomp4';

  



  I hope someone has an solution for me. Thanks

  


• x86inc : Avoid creating unnecessary local labels

  16 octobre 2015, par Henrik Gramner

  x86inc : Avoid creating unnecessary local labels
  The REP_RET workaround is only needed on old AMD cpus, and the labels clutter
  
  up the symbol table and confuse debugging/profiling tools, so use EQU to
  
  create SHN_ABS symbols instead of creating local labels. Furthermore, skip
  
  the workaround completely in functions that definitely won’t run on such cpus.
  This patch doesn’t modify any emitted instructions, and doesn’t actually affect
  
  x264 at all. It’s only for other projects that use x86inc.asm without an
  
  appropriate `strip` command in their buildsystem.
  Note that EQU is just creating a local label when using nasm instead of yasm.
  
  This is probably a bug, but at least it doesn’t break anything.

• Making half an image transparent from the command line

  14 octobre 2016, par Alex Konetchy

  I don’t really know where to start with this one. I’m trying to do something that I thought would be relatively simple to accomplish with imagemagick, but I don’t know the exact command to start with. I need to draw a line through an image, and then make everything above the line transparent in the image, and make everything below the line, the orignal image. What would be the best way to accomplish this using imagemagick ?

  So what I’ve come up with for now is to crop the image, and then resize it to the original size, but with a transparent background. The command I use is this, but it always comes out black. I’m not understanding why.

  convert -background none -gravity south out.png -resize 400x200 -extent 400x400 result.png

  Thanks for all of the help !
