• Running FFMPEGJS in a React Project

  23 mars 2020, par beek

  I’m trying to get https://github.com/ffmpegjs/ffmpeg.js/ running in a Create React App build project.

  import {createWorker} from '@ffmpeg/ffmpeg';

  When I import the library the build fails with

  ./node_modules/@ffmpeg/ffmpeg/src/createWorker.js
  
  Module parse failed: Unexpected token (21:4)
  
  You may need an appropriate loader to handle this file type.
  
  |     logger,
  
  |     progress,
  
  |     ...options
  
  |   } = resolvePaths({
  
  |     ...defaultOptions,

  I’m not sure how to handle this, or where the problem might be. Is this a Webpack issue ?

• Keep getting WIN32Exception when running FFMPEG in ASP.NET project

  23 octobre 2014, par Lance Bloom

  I have an ASP.NET project and I want to use FFMPEG to help create thumbails for my videos. I’ve loaded FFMPEG into the project, and whenever I run my code I get the same error :

  ’ffmpeg.MainModule’ threw an exception of type ’System.ComponentModel.Win32Exception’
  "A 32 bit processes cannot access modules of a 64 bit process."

  I’m using VS 2013, and I’ve set my target platform to x86, and made 100% sure I am using the 32bit version of ffmpeg. I’m using the static libraries from this site (http://ffmpeg.zeranoe.com/builds/) I also tried to change the target platform to All CPUs or x64, and tried with both 32 and 64 bit versions of FFMPEG. Always the same error. I am running IIS Express when I test in my local environment.

  Here is my code. Would appreciate any help !

  String vSource = "http://example.com/myvideo.mp4";
  
  String path1 = HttpContext.Current.Request.PhysicalApplicationPath;
  
  
  
  Process ffmpeg = new Process();
  
  ProcessStartInfo startinfo = new ProcessStartInfo(HostingEnvironment.MapPath("~/App_Data/exe/ffmpeg.exe"), "-i " + vSource + "-ss 00:00:05.000 -f image2 -vframes 1 " + path1 +"thumbnail1.jpg");
  
  
  
  startinfo.RedirectStandardError = true;
  
  startinfo.RedirectStandardOutput = true;
  
  startinfo.RedirectStandardInput = true;
  
  startinfo.UseShellExecute = false;
  
  startinfo.CreateNoWindow = true;
  
  ffmpeg.StartInfo = startinfo;
  
  
  
  ffmpeg.Start();

• Android NDK w/ ffmpeg library - error running project

  11 novembre 2014, par ynnadkrap

  Using this guide, http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/, I successfully compiled ffmpeg-2.4.2 with Android NDK 10, but now I’m having issues using it in my eclipse project.

  The error I’m getting :

  *** Android NDK: Aborting    .  Stop.

  which points to this in prebuilt-library.mk :

  ifndef prebuilt
  
  $(call __ndk_info,ERROR:$(LOCAL_MAKEFILE):$(LOCAL_MODULE): LOCAL_SRC_FILES points to a missing file)
  
  $(call __ndk_info,Check that $(prebuilt_path) exists, or that its path is correct)
  
  $(call __ndk_error,Aborting) <----- ***** This line is specifically pointed out by the error log
  
  endif

  Here’s my ...jni/Android.mk :

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  
  
  LOCAL_MODULE    := VideoTest
  
  LOCAL_SRC_FILES := videotest.c
  
  LOCAL_LDLIBS := -llog -ljnigraphics -lz -landroid
  
  LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil
  
  
  
  include $(BUILD_SHARED_LIBRARY)
  
  $(call import-module,ffmpeg-2.4.2/android/arm)

  Here’s my android-ndk/sources/ffmpeg-2.4.2/android/arm/Android.mk :

  LOCAL_PATH:= $(call my-dir)
  
  
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE:= libavcodec
  
  LOCAL_SRC_FILES:= lib/libavcodec-55.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
  
  include $(PREBUILT_SHARED_LIBRARY)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE:= libavformat
  
  LOCAL_SRC_FILES:= lib/libavformat-55.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
  
  include $(PREBUILT_SHARED_LIBRARY)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE:= libswscale
  
  LOCAL_SRC_FILES:= lib/libswscale-2.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
  
  include $(PREBUILT_SHARED_LIBRARY)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE:= libavutil
  
  LOCAL_SRC_FILES:= lib/libavutil-52.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
  
  include $(PREBUILT_SHARED_LIBRARY)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE:= libavfilter
  
  LOCAL_SRC_FILES:= lib/libavfilter-3.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
  
  include $(PREBUILT_SHARED_LIBRARY)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE:= libwsresample
  
  LOCAL_SRC_FILES:= lib/libswresample-0.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
  
  include $(PREBUILT_SHARED_LIBRARY)

  Here’s my project structure :

  So it seems to me that the project isn’t building because the LOCAL_SRC_FILES doesn’t point to anything, but is it referring to LOCAL_SRC_FILES in jni/Android.mk or the one in ...ffmpeg-2.4.2/android/arm/Android.mk ? Either way, it seems like they are actually pointing to something. I’ve also tried looking at this solution, Android NDK : Aborting stop ?, but I’m having a hard time understanding it. Which Android.mk file needs changing ?
