Subject: - if you don't know the timestamp, don't try to guess. Send an invalid one.
X-Git-Tag: 1.19.3~505^2~4570
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c19744b41991eec8c5e27d68194e2b88e285eff7;p=platform%2Fupstream%2Fgstreamer.git

- if you don't know the timestamp, don't try to guess. Send an invalid one.

Original commit message from CVS:
- if you don't know the timestamp, don't try to guess. Send an invalid one.
- use new macro GST_CLOCK_TIME_IS_VALID
- send the first buffer, too (funny that nobody noticed for ages, that we don't send the first audio buffer ever, no?)
