• StdioURLProtocolHandlerTest failed while Xuggler build under Windows

  26 mars 2012, par Dims

  Trying to build Xuggler under Windows. My Windows is x64 Win 7 prof, but all used libraries are 32bit. I am running build procedure under MinGW/MSys, from under Msys shell with the followinf script :

  #!/bin/sh
  
  export JAVA_HOME=/C/Program\ Files\ \(x86\)/Java/jdk1.6.0_25
  
  export XUGGLE_HOME=/C/Xuggler
  
  
  
  PATH=$XUGGLE_HOME/bin:/C/Program\ Files\ \(x86\)/Java/jdk1.6.0_25/bin:/d/APPS/msysgit/msysgit/bin/git:/D/APPS/MinGW/bin:/bin:/D/APPS/apa    che-ant-1.8.2/bin:/D/Users/Dims/Design/MinGW/Util:$PATH
  
  ant -Dbuild.m64=no run-tests

  The error follows

   [exec] Running 6 tests..
  
   [exec] In StdioURLProtocolHandlerTest::testRead:
  
   [exec] ../../../../../../../../../test/csrc/com/xuggle/xuggler/io/StdioURLProtocolHandlerTest.cpp:108: Error: Expected (4546420 == totalBytes), found (4546420 != 1042)

   [exec] Failed 3 of 6 tests
  
   [exec] Success rate: 50%
  
   [exec] FAIL: xugglerioTestStdioURLProtocolHandler.exe

  My questions is : did anybody did this on Windows and did he/she have this test passed ? :)

  UPDATE 1

  The test code is follows :

  int32_t totalBytes = 0;
  
  do {
  
      unsigned char buf[2048];
  
      retval = handler->url_read(buf, (int)sizeof(buf));
  
      if (retval > 0)
  
           totalBytes+= retval;
  
  } while (retval > 0);
  
  VS_TUT_ENSURE_EQUALS("", 4546420, totalBytes);

  While the url_read code is follows :

  int
  
  StdioURLProtocolHandler :: url_read(unsigned char* buf, int size)
  
  {
  
      if (!mFile)
  
          return -1;
  
      return (int) fread(buf, 1, size, mFile);
  
  }

  I don't understand, under what circumstances it can return 1042 ??? May be 64 bits play here somehow ?

  UPDATE 2

  I printed out filename used and it was

  d:/......./../../../test/fixtures/testfile.flv

  the path is correct, but started with d:/ not with /d/

  Can this play a role under Msys ?

• extract audio with youtube-dl on windows

  12 mars 2017, par FlyingNimbus

  I want to extract audio from a video downloaded with youtube-dl on windows. I got youtube-dl working, but am unable to extract the audio. This problem is caused due to not having the correct audio codes installed. When i try to extract audio it tells me the following :

  ’WARNING : unable to obtain file audio codes with ffprobe’

  youtube-dl man sais the following :
   x -extract-audio convert video files to audio-only files (requires ffmpeg or avconv and ffprobe or avprobe)

  How do I install ffprobe or ffmpeg ? Do I install this on windows, or do I install this as a python extension ? I have no idea, can someone point me in the right direction ?

  OS : windows 7
