Thibault Saunier b46718b1a0 audiotestsrc: Fix the way we compute EOS in reverse playback ... In reverse playback we were not taking into account the current buffer samples to check if we had reached EOS which was leading to a buffer with PTS = CLOCK_TIME_NONE containing too many frames followed by a useless buffer with pts=0 duration=0, and a g_critical issue in gst_object_sync_values. Also add a validate based test case. Without that patch this is how the expectation fails: ``` diff --- log-asink-sink-expected 2020-05-22 23:22:42.654384579 -0400 +++ log-asink-sink-actual 2020-05-22 23:29:35.671586380 -0400 @@ -27,5 +27,6 @@ buffer: pts=0:00:00.058820861, due=0:00:00.023219955, flags=discont buffer: pts=0:00:00.035600907, due=0:00:00.023219954, flags=discont buffer: pts=0:00:00.012380952, due=0:00:00.023219955, flags=discont -buffer: pts=0:00:00.000000000, due=0:00:00.012380952, flags=discont +buffer: due=0:00:00.012380953, flags=discont +buffer: pts=0:00:00.000000000, flags=discont event eos: (no structure) ``` Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/merge_requests/667>		2020-05-25 08:19:02 +00:00
