Seek With Alaw pipeline

[Anuroop Jesu]

Hi,

Does any one tried the seek on alaw pipeline.

I could able to record and playback the alaw file but seek forward and
backward on the

pipeline is failing.

Below is the code for seek which works perfectly fine for the mp3 playback
pipeline.


static void seekMediaTime (int ff, int time_seconds)
{
   gint64 start_pos, stop_pos, rate;
   gint64 start_flag, stop_flag;
   gint64 pos, len, tmp = 0;
   gint64 timeFf = FF_SPEED_BASE;
   GstFormat fmt = GST_FORMAT_TIME;

   /* If media is not playing */
   if (recordEng.recStatus != REC_PAUSE)
         return;

   gst_element_query_duration (recordEng.recPipeline, &fmt, &len);
   gst_element_query_position (recordEng.recPipeline, &fmt, &pos);

   if (ff == 0)
   {
         timeFf = ((gint64)FF_SPEED_BASE * time_seconds);

         if ((len <= (pos + timeFf)) || (len == pos))
               timeFf = 0;
         else
               tmp = pos + timeFf;
         printf ("FORWARDWORD BY:%llu\r\n",timeFf);
   }
   else
   {
         timeFf = ((gint64)FF_SPEED_BASE * time_seconds);

         if ((pos <= timeFf) || (len == pos))
               timeFf = 0;
         else
               tmp = (pos - timeFf);
         printf ("BACKWORD BY:%llu\r\n",timeFf);
   }
   g_print ("Current Pos Time: %llu %llu\r\n",pos,len);
   g_print ("Set Pos Time: %llu\r\n",tmp);
   timeFf = tmp;
   rate = 1.0;
   start_pos = timeFf;
   start_flag = GST_SEEK_TYPE_SET;
   stop_flag = GST_SEEK_TYPE_NONE;
   stop_pos = GST_CLOCK_TIME_NONE;

   if (recordEng.recStatus == REC_PLAYING)
      gst_element_set_state(GST_ELEMENT(recordEng.recPipeline),
                GST_STATE_PAUSED);

   if (!gst_element_seek (recordEng.recPipeline, rate,
          GST_FORMAT_TIME, GST_SEEK_FLAG_FLUSH,
          start_flag, start_pos,
          stop_flag, stop_pos))
   {
           g_print ("Seek failed!\r\n");
   }
   else
   {
           g_print ("Time: %" GST_TIME_FORMAT " / %"
              GST_TIME_FORMAT "\r\n",
              GST_TIME_ARGS (pos), GST_TIME_ARGS (len));

           /* We will wait til it is running or failed */
           if (gst_element_get_state (recordEng.recPipeline,
                NULL, NULL, -1) == GST_STATE_CHANGE_FAILURE)
           {
                 g_print ("Failed to go into PLAYING state\r\n");
           }
   }

   if (recordEng.recStatus == REC_PLAYING)
           gst_element_set_state(GST_ELEMENT(recordEng.recPipeline),
           GST_STATE_PLAYING);
}
