progressreport: Progress report message is not reporting percent-double and percentage for some files

Submitted by Vinod Kesti @vinodkesti

Link to original bug (#795003)

Description

progressreport message pattern is inconsistent with some file
Below are the behaviour.

1. When file processing start progressreport message contains percent-double and percentage
2. After some time percentage details are missing in the message.
3. This issue is observed when system is loaded with multiple file processing.

Further analyses and found that issue comes when gst_pad_peer_query_duration (sink_pad, format, &total) function returns total = -1

I tried debugging but not able to figure out which element responds to the query.

Can some one help me to give pointer where the problem is
