• ffmpeg.a : No such file or directory while running ccViewer iOS Swift [closed]

  22 janvier 2023, par Sarwat

  I am running a build which is available in in GitHub (https://github.com/lithium0003/ccViewer/tree/v1.4.3) to connect direct storages through RCLONE (Google Drive, OneDrive etc.)

  


  I am following steps to compile which provided GitHub ccViewer readme
how to compile :

  


  if you did not set up, run these commands.

  


  sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/
brew install nasm
brew install yasm
prepare depencency

./chromecast.sh
cd work
./clone.sh
./build.sh
open with Xcode and compile

open workspace "ccViewer.xcworkspace"
select scheme "CryptCloudViewer" and build


  


  but I am getting ffmpeg.a not found. Please check attached images of Xcode and Command prompt.

• react cant find ffmpegwasm

  18 septembre 2024, par Martin

  I am trying to create a working example for ffmpeg wasm with react js in my browser.

  


  I have been following this very simple example :
https://www.youtube.com/watch?v=-OTc0Ki7Sv0&ab_channel=Fireship

  


  installed ffmpeg locally inside my react repo node_modules as seen here :


  


  And followed to tutorial video to edit the App.jsx so it looks like this :

  


  import React, { useState, useEffect } from &#x27;react&#x27;;&#xA;import &#x27;./App.css&#x27;;&#xA;&#xA;import { createFFmpeg, fetchFile } from &#x27;@ffmpeg/ffmpeg&#x27;;&#xA;const ffmpeg = createFFmpeg({&#xA;  log: true,&#xA;});&#xA;function App() {&#xA;  &#xA;  const [ready, setReady] = useState(false);&#xA;&#xA;  const load = async () => {&#xA;      console.log(&#x27;load()&#x27;)&#xA;      await ffmpeg.load();&#xA;      setReady(true);&#xA;  }&#xA;&#xA;  useEffect(()=>{&#xA;    load();&#xA;  }, [])&#xA;&#xA;  return (&#xA;    <div classname="App">&#xA;      content&#xA;    </div>&#xA;  );&#xA;}&#xA;&#xA;export default App;&#xA;&#xA;

  


  But this leads to error messages in my win10 command prompt terminal saying it cant find the ffmpeg files :

  


  [16:07:47] [snowpack] [404] Not Found (/node_modules/@ffmpeg/core/dist/ffmpeg-core.js)
[16:07:47] [snowpack] [404] Not Found (/node_modules/@ffmpeg/core/dist/ffmpeg-core.wasm)
[16:07:47] [snowpack] [404] Not Found (/node_modules/@ffmpeg/core/dist/ffmpeg-core.worker.js)


  


  I've even tried moving the ffmpeg files to my public folder and editing the code to find them like so :

  


  const ffmpeg = createFFmpeg({
  log: true,
  corePath: '../public/@ffmpeg/core/dist/ffmpeg-core.js',
});


  


  But the same error occured. Why doesn't my react App.jsx file correctly find the ffmpeg files in my node_modules folder ?

  


• Can't save matplotlib animation

  19 novembre 2014, par renger

  I am trying to get a simple animation saved using ffmpeg. I followed a tutorial to install ffmpeg, and I can now access it from the command prompt.

  Now I run this piece of code :

  import numpy as np
  
  from matplotlib import pyplot as plt
  
  from matplotlib import animation
  
  
  
  fig = plt.figure()
  
  ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
  
  line, = ax.plot([], [], lw=2)
  
  
  
  def init():
  
      line.set_data([], [])
  
      return line,
  
  
  
  def animate(i):
  
      x = np.linspace(0, 2, 1000)
  
      y = np.sin(2 * np.pi * (x - 0.01 * i))
  
      line.set_data(x, y)
  
      return line,
  
  
  
  anim = animation.FuncAnimation(fig, animate, init_func=init,
  
                                 frames=200, interval=20, blit=True)
  
  
  
  mywriter = animation.FFMpegWriter()
  
  anim.save('mymovie.mp4',writer=mywriter)
  
  
  
  plt.show()

  I get this error :

  Traceback (most recent call last):

  WindowsError: [Error 2] Het systeem kan het opgegeven bestand niet vinden
  
  </module></module></stdin>

  The last dutch sentence does mean something like : The system can’t find the specified file.

  What do these errors mean, and how can I solve them ?
