Subject: concat: Reset segment base offset after FLUSH_STOP with reset_time = TRUE
X-Git-Tag: 1.6.1~248
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=25c66e60045e44d50a591f5d62706f6f243bb9ca;p=platform%2Fupstream%2Fgstreamer.git

concat: Reset segment base offset after FLUSH_STOP with reset_time = TRUE

If the reset_time value of a FLUSH_STOP event is set to TRUE, the pipeline
will have the base_time of its elements reset. This means that the concat
element's current_start_offset has to be reset to 0, since it was
calculated with the old base-time in mind.

Only FLUSH_STOP events coming from the active pad are looked at.
