852 |

|
|
854 |
+ * segment.
|
|
|
855 |
+ *
|
|
|
856 |
+ * Then, query the running times of the new audio and video pads that you will
|
|
|
857 |
+ * switch to. Naturally, these pads are on separate switch elements. Take the
|
|
|
858 |
+ * minimum running time for those streams and use it for the time at which to
|
|
|
859 |
+ * open the new segment.
