From 5c6a2d9878f12da2730e06fbcc79f35d82f906cf Mon Sep 17 00:00:00 2001 From: Michael Niedermayer Date: Thu, 17 Nov 2011 19:38:47 +0100 Subject: [PATCH] ac3probe: Detect Sonic Foundry Soft Encode AC3 as raw AC3. Our ac3 code chain can handle it fine. More ideal would be to write a demuxer that actually extracts what can be from the additional headers and uses it for whatever it can be used for.
