• Installing gifify on Windows

  12 octobre 2017, par Robert Wojciechowski

  So gifify is a pretty awesome script that converts videos to gifs via command line : https://github.com/vvo/gifify

  I’m keen to get this working on my Windows 10 machine. I’m pretty new to windows and relatively new to coding, but I was able to get a few things working, but ran into a problem.

  Here is what I did :

  1. Installed node.js + npm
  2. Installed FFmpeg using npm
  3. Installed ImageMagick using npm (i think i did this wrong, might have only installed the wrapper).
  4. Downloaded giflossy. It needed to be built (?)
  5. Installed Visual Studio 2015, tried to build it using nmake and got this error :

  NMAKE : fatal error U1073: don't know how to make 'win32cfg.h'

  The command I used was :

  PS C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin> .\nmake -f "C:\Users\Robert's Workstation\.npm-global\node_modules\giflossy-lossy-1.82.1\src\Makefile.w32"

  Would really appreciate some help with this :D

• Streaming android to windows

  13 juin 2017, par iYehuda

  I’m writing an app that enables controlling android devices from windows machines.
  Major part of controlling the device is viewing it’s screen. Currently, my android app (Java code) captures the screen on a fixed rate, compresses it (JPEG) and sends it, while the windows side (C# code) receives buffers of data, each for frame, decompresses them and displays the last decompressed frame.

  Two issues came up from this solution :

  1. Compression of a single image takes 0.3 seconds, which limits me to low FPS streaming with single thread for compressing. I made a thread pool for compressing captured frames, and it damages the app performance.

  2. The compression is not optimal. The screen can be idle for a while and a continuous transmission of the same frame would be done. Usage of streaming/encoding format would be handful and can ease the network traffic.

  I searched for encoding APIs such as MediaCodec and third party libraries such as ffmpeg. All those libraries encode videos and write them to files (maybe I misunderstood them ?).

  What API can I use for streaming my screen and follow these requirements :

  • Fast encoding / non blocking API
  • Outputs raw binary data for each frame. The data must be sent immediately
  • Can be embedded into my existing applicative protocol (protocol buffers based)
  • Available on C# (Windows) and Java or C++ (Android)
