• Customizing HomeKit (using HomeBridge plug-in or building custom app ?)

  5 mai 2019, par Fréderic Cox

  I am running HomeBridge on a RBPi3 and displaying my home accessories through an iPad hub running the Home app.

  I really like it but I’m missing some things like a big clock (The iPad is hanging on my kitchen wall with screen-on display most of the day), a summary of my Google Calendar and some other nice widgets. It is not possible to add those widgets to the Home app (typically so with Apple software .. :-)) but I’m looking for a solution to achieve this.

  I have two options (at least that’s what I think) :

  1) Build my own iPad using the HomeKit API where I can then customize the app appearance and add the widgets the way I want.

  2) Using HomeBridge FFMpeg camera plugin and creating a video stream containing a big clock and some calendar item titles.

  Option 1 is the most work but also provides the flexibility. Option 2 is easier but limited in functionality. Option 2 might also be a performance overkill to have a video stream ? The video stream would provide me with the advantage that the camera widget in HomeKit is pretty big and clearly visible from distance (the clock at least).

  What do you think is the best option and how would option 2 be achieved ? How can I set up a video stream from for example a SWF file created in Adobe Animate ? Or how to achieve this dynamic info inside a video stream ?

  Any tips are most welcome ! Thanks

• FFMpeg with PHP-7.0 on Ubuntu

  25 octobre 2018, par Gabriel Bueno Lemes da Silva

  I have a NGINX server with PHP-7.0 and I would like to install the ffmpeg-php extension. I’ve been trying for a few days now and in many ways.

  The method that worked so far was compiling ffmpeg (https://ffmpeg.org/releases/ffmpeg-4.0.2.tar.bz2) manually, but when trying to compile ffmpeg-php (https: // sourceforge. net / projects / ffmpeg-php / files / ffmpeg-php / 0.6.0 / ffmpeg-php-0.6.0.tbz2 / download) I am encountering the following error message :

  Can someone give me a light ? I do not know what else to do !

• Making use of -w option in pyinstaller does not start/create the subprocess in python

  15 novembre 2018, par User

  I am making use of python to invoke ffmpeg to start and stop video capturing. I do not want to the console window appear when my python exe starts. The code I have currently to start and stop video recording is below,

  cmd = '\\ffmpeg\\bin\\ffmpeg.exe -loglevel quiet -f gdigrab -framerate 30 -i desktop -vcodec libx264 -pix_fmt yuv420p -preset slow -crf 0 -threads 0 ' + '"' + final_file_for_video_processing + '"'
  
  
  
  def stop_screen_recording():
  
      sub_process.stdin.write("q".encode())
  
      stdOutput, stdError = sub_process.communicate()
  
  
  
  
  
  def stop_screen_recording(cmd):
  
      startupinfo = subprocess.STARTUPINFO()
  
      startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
  
      global sub_process
  
      sub_process = subprocess.Popen(cmd, startupinfo=startupinfo, 
  
      stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=None)
  
      sub_process.wait()

  The challenge faced is, when I build the exe using
  pyinstaller -w —onefile python_file_name.py the recording does not begin. Note : The -w is to not show the console window.

  If I were to make use of pyinstaller and build the exe in the following way,
  pyinstaller —onefile python_file_name.py then recording of the video begins.
  Note : Without the -w command it works perfectly fine.

  I want to make use of the -w command since I do not want to show the console window of my python exe. Any insights will help.
