• I'm getting error while building the project in vue for ffmpeg.wasm

  2 avril, par EaBengaluru

  Hi i'm getting below error when i build the project with $npm run build command

  


  

  


  I'm using vuetify "vuetify": "^2.4.0" still because 3.0 is still in beta so i'm using "vue": "^2.6.11",

  


  Here is my package.json

  


  {
   ....
   "dependencies": {
      "@ffmpeg/core": "^0.11.5",
      "@ffmpeg/ffmpeg": "^0.11.0",
      "core-js": "^3.6.5",
      "vue": "^2.6.11",

  in my vue.config.js there is nothing much , except transpileDependencies

  


  module.exports = {
  transpileDependencies: [
    'vuetify'
  ]
}

  Note : i want to use vuetify

  


  Question : i want to build with "@ffmpeg/core": "^0.11.0", "@ffmpeg/ffmpeg": "^0.11.5" and vuetify

• Can not Record screen with headless chrome and FFmpeg

  26 janvier 2018, par Bill.Zhuang

  Before i used xvfb to render chrome, use selenium do button clicks, and use FFmpeg to capture it with -f x11grab.

  Now i want to use headless chrome to render my target site, i found i can not record the screen as before, seems FFmpeg not support yet.

  I have tried an idea like generate lots of screenshots and pipe to FFmpeg -f image2pipe, but it looks bit weird. I’m looking for more "native" way to do that.

  what’s the correct way in do that ? or i still need go back to xvfb solution ?

• exception on ffmpeg dll from a c++ visual studio 2015 project

  1er juillet 2017, par user1019140

  I want to use ffmpeg library in a Visual Studio project.
  I want to build an app for WIN32, so I downloaded :

  C:\Users\exa\Downloads\ffmpeg-3.3.2-win32-shared.zip
  
  C:\Users\exa\Downloads\ffmpeg-3.3.2-win32-dev.zip

  I copied the dlls from the shared zip to the same directory as my generated exe file. And I unzipped the dev zip into a directory of a different project of the same solution called MEDIA_IO.

  Then in the project properties , I added "additional include directories" :

  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\include

  and under the linker, I added "Link library dependencies" :

  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib

  and "Additional dependencies" :

  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\swscale.lib
  
  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\avutil.lib
  
  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\avcodec.lib
  
  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\avformat.lib
  
  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\avfilter.lib
  
  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\postproc.lib
  
  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\swresample.lib
  
  ..\MEDIA_IO\ffmpeg-3.3.2-win32-dev\lib\avdevice.lib

  I include the headers using :

  extern "C"
  
  {
  
  #include <libavcodec></libavcodec>avcodec.h>
  
  #include <libavformat></libavformat>avformat.h>
  
  #include <libavutil></libavutil>imgutils.h>
  
  #include <libavutil></libavutil>samplefmt.h>
  
  #include <libswscale></libswscale>swscale.h>
  
  #include <libavutil></libavutil>avstring.h>
  
  #include <libavutil></libavutil>intreadwrite.h>
  
  }

  The app compiles fine, but when running it, I’m getting exceptions on many different ffmpeg functions.

  For examples, when running :

  SwsContext * ctx = sws_getContext(560, 320, AV_PIX_FMT_YUV420P, 560,320, AV_PIX_FMT_RGB24, 0, NULL, NULL, NULL);

  I get exception :

  Exception thrown at 0x57E05140 (swscale-4.dll) in UnitTest1.exe: 0xC0000006: In page error executing location 0x57E05140 (status code 0xC0000008).
  
  Unhandled exception at 0x57E05140 (swscale-4.dll) in UnitTest1.exe: 0xC0000006: In page error executing location 0x57E05140 (status code 0xC0000008).

  It does not tell what are status codes 0xC0000006 and 0xC0000008.
  I dug a lot and could not find the source of the problem.
