Subject: streamsynchronizer: reset eos on STREAM_START
X-Git-Tag: 1.22.7~246
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dd6e889073003105796890385308c727d5ecbc37;p=platform%2Fupstream%2Fgstreamer.git

streamsynchronizer: reset eos on STREAM_START

self->eos was never reset after streamsynchronizer has sent EOS
(except on explicit flush or switching back to PAUSED).
As a result, synchronization was broken if new streams were pushed later
as gst_stream_synchronizer_wait() does not wait if self->eos is set.

Fix this by reseting self->eos on STREAM_START as that means a new
stream is being sent upstream and so a new EOS will follow later on.
