v0.4.1

This is a bug fix release.

Improvement & Fix

• Fix Matroska export requirements check. Matroska export was incorrectly discarded when the micro part of GStreamer version was not 1.
• Add tool tips.

Limitations

• Exporting the TOC to a Matroska container requires gst-plugins-good 1.14 or above.
• Prior to version 1.14, the GStreamer decoding element used for media playback enters a loop after the end of stream which causes high CPU usage.
