+
+ * Add subtitle view.
+
+ 2014-06-03 Carl Hetherington <cth@carlh.net>
+
+ * Fix bad resampling of separate sound file sources that
+ have specified video frame rates.
+
+ * Version 1.69.20 released.
+
+ 2014-06-03 Carl Hetherington <cth@carlh.net>
+
+ * Re-calculate and update audio plots when the mapping is changed.
+
+ * Change the -3dB preset to -6dB since we are talking about
+ amplitude, not power.
+
+ * Version 1.69.19 released.
+
+ 2014-06-02 Carl Hetherington <cth@carlh.net>
+
+ * Empirical hack to prevent over-read of array
+ by libswscale; may fix crashes at the start of
+ DCP encodes.
+
2014-05-29 Carl Hetherington <cth@carlh.net>
* Version 1.69.18 released.
