From 631b89ddde44dfc8b72b904d8c41368b2c02d037 Mon Sep 17 00:00:00 2001 From: Yoann Lopes Date: Fri, 29 Jan 2016 15:18:33 +0100 Subject: DirectShow: refactor custom renderer filter Refactor out some of the filter and pin logic into the DirectShowBaseFilter and DirectShowPin abstract classes. This will avoid code duplication when implementing the probe filter. The existing source filter (for qrc files) can also be refactored to use these abstract classes.
