From 4f4ee9ee88720e27b2e90e5dc3d9c086b069a316 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Wed, 23 Jul 2014 12:28:44 -0300 Subject: [PATCH] [media] coda: move H.264 helper function into separate file Currently there is only the coda_h264_padding function, but we will have to add more H.264 specific helpers later.
