  4 novembre 2013, par helloworld

  I am trying to run this code (It did work on my previously server, but now i keep getting this annoying error) :

  ffmpeg -loop 1 -r 25 -t 322 -i /home/kampmann/public_html/m/xxx/movie_10262.jpg -q:v 1 -an /home/kampmann/public_html/m/xxxs/573240.mp4 2>&1

  Error :
  Invalid value '1' for option 'loop'

  Here is my output.

• Unable to link with libx264.lib static library

  3 novembre 2013, par dtumaykin

  I’m building custom video encoder using x264 as a static library. I’ve followed this guide in order to build static library. Trying to compile this :

  x264_t * setup_encoder(int width, int height){
  
      x264_param_t param;
  
      x264_param_default_preset(&param, "veryfast", "zerolatency");
  
      param.i_threads = 1;
  
      param.i_width = width;
  
      param.i_height = height;
  
      param.i_fps_num = 26;
  
      param.i_fps_den = 1;
  
      // Intra refres:
  
      param.i_keyint_max = 26;
  
      param.b_intra_refresh = 1;
  
      //Rate control:
  
      param.rc.i_rc_method = X264_RC_CRF;
  
      param.rc.f_rf_constant = 25;
  
      param.rc.f_rf_constant = 25;
  
      param.rc.f_rf_constant_max = 35;
  
      //For streaming:
  
      param.b_repeat_headers = 1;
  
      param.b_annexb = 1;
  
      x264_param_apply_profile(&param, "baseline");
  
  
  
      return x264_encoder_open(&param);
  
  }

  Results in :

  main.obj : error LNK2019 : unresolved external symbol "int __cdecl x264_param_default_preset(struct x264_param_t *,char const *,char const *)"

  main.obj : error LNK2019 : unresolved external symbol "int __cdecl x264_param_apply_profile(struct x264_param_t *,char const *)"

  main.obj : error LNK2019 : unresolved external symbol "struct x264_t * __cdecl x264_encoder_open_136(struct x264_param_t *)"

  %PROJECT_DIR% : fatal error LNK1120 : 3 unresolved externals

  Linker scans libx264.lib, but can’t find anything inside.

  Searching .\lib\libx264.lib:

  With dumpbin /HEADERS I can actually find the declaration I need, but linker is unable to do it.

• FFMPEG Detect volume of streaming (PHP)

  22 septembre 2013, par Mohamed Mostafa

  I spent last 4 days trying to acheive that but with no luck,

  I am trying to detect volume of streaming link or save audio file, using the FFmpeg I tried every single command line.

  ffmpeg -f lavfi -i amovie=sample1.aac,volumedetect -f null -y test.txt

  Output

  Basically my problem now is :

  Any help please
