Ciao Nico,

Two gdb logs, at:

http://www.bqbsoftware.ie/mplayer_logs/audio_usage/

(1) 2106_audio_usage_gdb

     Trace just confirming that audio_time_usage is high.

(2) 2106_audio_usage_gdb1

     This trace allows 100 video frames to display and
     then prints out audio_time_usage and sh_video->timer.


There is something wrong with the jumps in audio_time_usage.

I will keep tracing but wanted to let you know how far I've
gotten.

   // Fill buffer if needed:
   current_module="decode_audio";   // Enter AUDIO decoder module
   t=GetTimer();
   while(sh_audio->a_out_buffer_len<playsize && !d_audio->eof){
     int  
ret=decode_audio(sh_audio,&sh_audio->a_out_buffer[sh_audio->a_out_buffer_len],
         playsize-sh_audio->a_out_buffer_len,sh_audio->a_out_buffer_size-sh_audio->a_out_buffer_len);
     if(ret<=0) break; // EOF?
     sh_audio->a_out_buffer_len+=ret;
   }
   t=GetTimer()-t;
   tt = t*0.000001f; audio_time_usage+=tt;


What could cause decode_audio() to take longer than it
really should?

Why is 't' multiplied by 0.000001f?


Dermot.
