• Connecting ffmpeg java module to named pipe

  27 novembre 2019, par Ehsan5

  I want to extract the output of folowing ffmpeg Module with the help of Named pipe. I am currently having problems with communication of ffmpeg and named pipe, but thank you for explaining how to extract stream bytes from output named pipe and convert it to images.

  My code gives socket connection error when using named pipe. I have used method that suggested in ffmpeg main page (pipe:0 for input and pipe:1 for output) but because it is not named pipe I cannot use it in the client side. It should be noted that named pipe is opened successfully with jna win32 module.

  This is server side code(but i tested it with \\.\pipe\PIPE also) :

  FFmpegBuilder builder = new FFmpegBuilder()
  
  .setInput(input.getPath())
  
  .addOutput(" -f avi pipe:1 ")
  
  .addExtraArgs(videoFilterStr)
  
  .done();
  
  UUID caller = UUID.randomUUID();
  
  try {FFmpegHelper.builder().progressListener().build().run(builder, caller)...

• react-native-ffmpeg : Native module cannot be null (ios) and null is not an object (evaluating 'RNFFmpegModule.enableLogEvents') (android)

  4 mars 2020, par foxtrotuniform6969

  I have a basic expo project that I’ve eject as expokit, and proceeded to run expo install react-native-ffmpeg. When then running expo start I was greeted with Native module cannot be null on my iOS device and null is not an object (evaluating  'RNFFmpegModule.enableLogEvents').

  After that, I re-read the react-native-ffmpeg documentation and added pod 'react-native-ffmpeg', :podspec => '../node_modules/react-native-ffmpeg/ios/react-native-ffmpeg.podspec' to my ios/Podfile and ran pod install. Still no luck.

  After that, I deleted the node_modules folder and yarn.lock file, re-ran yarn, went into the ios directory, deleted the Pods folder and Podfile.lock file and re-ran pod install and still had no luck !

  The error is less than helpful. Any ideas where to look ?
