Description Thiago Sousa Santos 2007-06-08 14:07:42 UTC 
Please describe the problem:
oggdemux is not able to work on pull mode with queue2 because the duration query it sends upstream doesn't get answered.

Steps to reproduce:
1. use a pipeline that links queue2 to oggdemux and set temp-location property on queue2
2. 
3. 


Actual results:
The application quits.

Expected results:
The application should play the stream.

Does this happen every time?
Yes

Fixes the problem

This patch will make queue2 block the query until it receives the first buffer (meaning that the upstream elements are at least paused). The query is then passed upstream and oggdemux can get the stream length.

        Based on patch by: Thiago Sousa Santos <thiagossantos at gmail dot com>

        * gst/playback/gstqueue2.c: (gst_queue_peer_query),
        (gst_queue_handle_src_query):
        Wait for preroll before attempting to forward a duration query upstream.
        Fixes #445505.
