From 84fce203bdfa39bfaa55571ac6627aa2320e646d Mon Sep 17 00:00:00 2001 From: John Stebbins Date: Mon, 4 Jul 2011 09:55:19 -0700 Subject: [PATCH] dca: set AVCodecContext frame_size for DTS audio Set the frame size when decoding DTS audio. This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields. Since frame_size is not currently set, the duration of a frame is being guessed based on the streams bitrate. But for DTS-HD, the bitrate currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly inaccurate frame duration estimate.
