From 5403dd4b6869cabcb8e2a0ed4d4f278983d1a15c Mon Sep 17 00:00:00 2001 From: Grigori Goronzy Date: Wed, 9 Oct 2013 02:23:48 +0200 Subject: [PATCH] radeon/uvd: try to fix VC-1 decoding MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The DPB size calculations seem to be off; there is various random corruption happening, even with advanced profile. Always assuming a minimum number of references appears to fix it, similarly to H.264. This might overallocate the DPB. Also clean up the SPS/PPS field setup so that it matches VC-1 specifications better. With these changes, all advanced profile VC-1 files I could get my hand on work fine.
