meta-agl-bsp: backport: gstreamer1.0 v1.4.5 recipes
This is a backport from Jethro as meta-rcar-gen3 append on following: - gstreamer1.0-libav_1.4.5 - gstreamer1.0-omx_1.2.0 - gstreamer1.0-plugins-bad_1.4.5 - gstreamer1.0-plugins-good_1.4.5 v2 (jsmoeller): Move into meta-rcar-gen3 subfolder as it only affects that layer.

+Subject: [PATCH] basesink: Fix QoS/lateness checking if subclass implements
+ prepare/prepare_list vfuncs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In basesink functions gst_base_sink_chain_unlocked(), below code is used to
+checking if buffer is late before doing prepare call to save some effort:
+ if (syncable && do_sync)
+ late =
+ gst_base_sink_is_too_late (basesink, obj, rstart, rstop,
+ GST_CLOCK_EARLY, 0, FALSE);
+
+ if (G_UNLIKELY (late))
+ goto dropped;
+
+But this code has problem, it should calculate jitter based on current media
+clock, rather than just passing 0. I found it will drop all the frames when
+rewind in slow speed, such as -2X.
