• FFMpeg Can't find libvorbis under Windows

  27 février 2014, par Water Lin

  I try to use FFMpeg to generate MKV video format. By default, FFMpeg will using h264 & libvorbis. But when I using the doc/examples/muxing.c under ffmpeg source file folder, there is always an error :

  [libvorbis @ 002e52a0] Specified sample format s16 is invalid or not supported
  
  Could not open audio codec: Error number -22 occurred

  I used Zeranoe FFmpeg and showed this error. I also tried to compile the ffmpeg from source under MinGW, and I also enable the libvorbis by following comfiguration :

  $ ./configure --prefix=/mingw --enable-libvpx --enable-libvorbis --enable-shared --enable-static

  Before I make, I also install libvorbis, libogg, yasm etc. But the error is still there.

  If I use the ffmpeg.exe to convert video to webm format, it works. The command is like following :

  ffmpeg -i test.h264 -vcodec libvpx -acodec libvorbis output.webm

  The generated output.webm can be played by Firefox or something else. So I think the compiled ffmpeg library is OK. But why I can't generate webm file in muxing.c code ?

• Ffmpeg headers do not compile in windows

  30 mai 2013, par Srv19

  I am trying to link to ffmpeg under windows, but have run into difficulties. Inclusion of ffmpeg headers causes hundreds of compilation errors which i can't easily fix.

  1) timestamp.h uses snprintf instead of _snprintf. I have tried to add it as a macro, like this :

  #ifdef Q_OS_WIN
  
  #define snprintf _snprintf
  
  #endif
  
  
  
  #define __STDC_CONSTANT_MACROS 
  
  namespace ffmpeg { 
  
  extern "C" {
  
  #include <libavutil></libavutil>imgutils.h>
  
  #include <libavutil></libavutil>samplefmt.h>
  
  #include <libavutil></libavutil>timestamp.h>
  
  #include <libavformat></libavformat>avformat.h>
  
  #include <libswscale></libswscale>swscale.h> 
  
  } }

  but it didn't help. Why would the macro not propagate inside ?

  2) There again, PRId64 isn't defined. I have defined __STDC_CONSTANT_MACROS before inclusion of timestamp.h, but definition isn't retrieved from inttypes.h

  In compiler output, it looks like :

  ffmpeg\include\libavutil/timestamp.h(42) : error C3861: 'snprintf': identifier not found
  
  
  
  ffmpeg\include\libavutil/timestamp.h(42) : error C2146: syntax error : missing ')' before 

  identifier 'PRId64'
