From 58b7677db01585736d2175f385dcfcc313aed3de Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 23 Jul 2014 12:28:43 -0300 Subject: [PATCH] [media] coda: move per-instance buffer allocation and cleanup This patch moves the context buffer allocation into the context start_streaming callbacks. The context buffer and internal framebuffer cleanup is moved into the context release callback.
