gst_element_seek() is failing !!
Locked

Hello All,
I am trying play a mp3 from constructing a pipeline using an application. It works fine as expected on my desktop. when I cross compile for ARM v7 , the seek is not happening. I am constructing pipeline using filesrc ! decodebin2 ! autoaudiosink my code snippet for seek is like this.. --------------------------------------------------------------------------------------- if (!(gst_element_query_position (pipeline, &fmt, &cur_pos))) printf("[player] : gst_element_query_position failed \n"); printf("current position before seek = %u\n", cur_pos); printf("GST_SECOND = %u\n", GST_SECOND); double new_pos_sec = cur_pos * (1.0 / GST_SECOND) + 10; // seek for 10 sec gint64 new_pos = new_pos_sec * GST_SECOND ; if(!(gst_element_seek (pipeline, 1.0, GST_FORMAT_TIME, GST_SEEK_FLAG_FLUSH, GST_SEEK_TYPE_SET, new_pos , GST_SEEK_TYPE_NONE, GST_CLOCK_TIME_NONE))) printf("[player] Seek failed!! \n"); -------------------------------------------------------------------------------- output is : current position before seek = 0 GST_SECOND = 0 [player] Seek failed!! --------------------------------------------------------- What could be the reason for GST_SECOND = 0 , on my desktop I am getting this value as 1000000000 & seek is happening as expected. -- Thanks & Regards, Satish Pattar _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Check the type of the cur_pos variable and also the printf format specifiers, they are likely wrong.

Hello Wim/ Stephan,
I was using incorrect format specifier , then I used the appropriate format specifier for printing gint64 , it printed correct value for GST_SECOND, however my current position i.e., cur_pos is still showing zero. Also I observed that call to "gst_element_query_duration" is always failing !!. This could be the reason for gst_element_seek() getting failed. I have no clue why it is failing. I checked the gst version on both my desktop as well as my ARM target & both are same (0.10.28). I wonder why it would be failing only in the target. Your inputs are appreciated.

I have also tried with playbin2 instead of pipeline, still the results are same.
Appreciate your inputs. Thanks , Satish P On Fri, Apr 29, 2011 at 7:33 PM, Wim Taymans <[hidden email]> wrote:
