From 9765ec18f65b8ae147660e0d71bfa80293e57f56 Mon Sep 17 00:00:00 2001 From: Ammon Riley Date: Wed, 26 Apr 2023 18:26:35 -0700 Subject: [PATCH] avcodec/mxfdec: Recognize AAC per SMPTE ST 381-4 This patch simply recognizes the AAC audio track during decode -- it does not add functionality to encode AAC in MXF.
