From ce083282f0a8b7d63c4047c30b7bac498f9806dd Mon Sep 17 00:00:00 2001 From: Rémi Denis-Courmont Date: Sat, 4 Oct 2014 16:55:04 +0300 Subject: vdpau: common support for managing the VdpDecoder in avcodec Using the not so new init and uninit callbacks, avcodec can now take care of creating and destroying the VDPAU decoder instance. The application is still responsible for creating the VDPAU device and allocating video surfaces - this is necessary to keep video surfaces on the GPU all the way to the output. But the application will no longer needs to care about any codec-specific aspects.
