From 11618110c2e17d6018ad5ec71ec0f357e900034d Mon Sep 17 00:00:00 2001 From: Yuqing Zhu Date: Mon, 4 Jul 2016 13:46:29 +0800 Subject: gstreamer1.0-plugins-bad: Implement multiple render targets for GLES3 There are numerous slight differences required between Desktop GL and GLES3 for multiple render targets. Need to realize it.
