From 82ecae8a7069104698d491000b37629cd8d96fd8 Mon Sep 17 00:00:00 2001 From: Steven Robertson Date: Tue, 10 Jul 2012 22:14:57 -0700 Subject: lavfi: add alphaextract and alphamerge filters These filters are designed for storing and transmitting video sequences with alpha using higher-efficiency codecs such as x264 which don't natively support an alpha channel. 'alphaextract' takes an input stream with an alpha channel and returns a video containing just the alpha component as a grayscale value; 'alphamerge' takes an RGB or YUV stream and adds an alpha channel recovered from a second grayscale stream.
