• wav oggenc html audio -> why it deosn't work in firefox

  19 avril 2016, par ghi

  I have very strange issue. I want to play ogg files on firefox using audio tag. But when I try to run this audio, firebug reporting this error :

  Media resource http://127.0.0.1/packhorse/src/sounds/558143.ogg could not be decoded.
  
  
  
  
  
  xhr.send( ( s.hasContent && s.data ) || null );
  
  
  
  jquery-1.8.2.js (wiersz 8416)
  
  All candidate resources failed to load. Media load paused.

  I creating this ogg files from wav files generated by timidity++ using oggenc command.
  When I’m trying to open this file directly in firefox, I get black screen with grey box and the following error :

  Video can't be played becouse the file is corrupt.

  But I don’t want to play video - it’s the audio file.

  I was thought that is some mime issue as long as I realized that on chrome everything work correctly. Have you know what can couse that problems ?

  You can download audio file which I want to play on firefox from here :

  avformat/dash : move reused API to common file and header file
  move from dashenc, move DASHTmplId and dash_fill_tmpl_params to
  
  dash.c, they will be used by dash demuxer and dash muxer.
  v2 fixed :
  
  1. rename common file from dashcomm.* to dash.*
  
  Suggested-by : Hendrik Leppkes <h.leppkes@gmail.com>
  v3 fixed :
  
  1. rename header file pre defined
  
  2. add ff_ prefix for the internal API

• Mingw-w64 - printf does not work

  27 décembre 2013, par Gosha U.

  First I wanted to modificate ffplay according to my requirments. Then I noticed that original ffplay from my build can't play some video files, but it didn't write any message to console. Then I noticed that ffmpeg also don't write any usage message when I run it without params. But it works. If I run it from terminal it's like running asynchronously ! The terminal just shows next row. I mean it asks for a next command. But the ffmpeg process is visible in task manager and it writes the output video file what I had requested !

  I created following souce file. I have modified the Makefile. So it have built the exe-file works just the same way. I have no idea how it can be.

  #include 
  
  #include "cmdutils.h"
  
  
  
  const char program_name[] = "hello";
  
  const int program_birth_year = 2013;
  
  
  
  void show_help_default(const char *opt, const char *arg)
  
  {
  
      printf("zxcvbnm\n");
  
  }
  
  
  
  int main(int argc, char **argv)
  
  {
  
      printf("1234567890\n");
  
      return 0;
  
  }

  And after that I created real hello world app with MinGW-w64 and qmake without eny extra libs. And its printf does not work.

  I want to prevent this behavior.

  I want to make printf working in traditional manner.

  How I build FFmpeg :
