• How to do FFMPEG live transcoding to HTML5 video from file(.MP4, .MKV) in PHP ?

  12 octobre 2014, par user3534650

  I’m using windows, tried to follow this tutorial and downloaded the code : blog page is http://sixserv.org/2010/11/30/live-transcoding-for-video-and-audio-streaming/ and the github https://github.com/4poc/php-live-transcode. It doesn’t work, I’m getting some errors in mplayer saying "MPlayer has not identified the file you provided".

  I just need a simple working live media transcoder that can work on most browsers even in mobile devices (HTML5) using FFMPEG in PHP. I’ve been searching this the entire time, I found nothing.

• About ffmepg. Some puzzles about using user defined filter

  12 novembre 2014, par Tian Gao

  All.

  I am just a starter in ffmpeg.

  I just downloaded it, and want to define the filter by myself. But, I met some problem, The filter I am to write is sure to be very complex, so I need use some class, which is define in cplusplus, to help me finish the task. So, I just created two files, .h file and .cpp file. And I want to define one specific class in these two files. And the class defined before, will be used in the filter file defined by my self. I know that the filter defined by users should be wrote as the strict formats. But, it always give out this wrong information,

  error: unknown type name 'class'

  And if i add some related lines, to command it compile the program by cplusplus, like this,

  #ifndef GY_FILTER_BLEND_H_
  
  #define GY_FILTER_BLEND_H_
  
  
  
  #include 
  
  #ifdef __cplusplus
  
  
  
  class testgy
  
  {
  
  public:
  
      int xx;
  
      testgy();
  
      ~testgy();
  
      void initial();
  
  
  
  };
  
  #endif
  
  
  
  #endif /* GY_FILTER_BLEND_H_ */

  This error info is to be shown,

  libavfilter/vf_gpu_scroll_left_right.c:64:5: error: unknown type name 'testgy'

  in vf_gpu_scroll_left_right.c , the related lines are as follows,

  #include "gy_filter_blend.h"
  
  
  
  AVFILTER_DEFINE_CLASS(tp_scroll_left_right);
  
  static av_cold int init(AVFilterContext *ctx)
  
  {
  
  
  
      TpScrollLeftDownContext *ctx_ptr = ctx->priv;
  
  
  
      testgy testGY;
  
      testGY.initial();
  
  
  
      __android_log_print(4 ,"gyy_1112" ,"testGY   = %d", testGY.xx);
  
      __android_log_print(4 ,"gyy_1112" ,"str   = %s", ctx_ptr->synthesisCmd0);
  
  
  
      tt  = gpu_filter_new(FILTER_TYPE_SCROLL_LEFT);
  
  
  
      gl_program_object_id_scroll_horizontal = -1;
  
      video_width = -1;
  
      video_height =-1;
  
  
  
      return 0;
  
  }

  So, The question is that I don’t know how to use the class defined by cplusplus, in c file. Anyone has some related experience before ?

  Thanks a lot !
