From 2b3d041cdc88fe556e61f70130a3a7eb024e0958 Mon Sep 17 00:00:00 2001 From: "Panagiotis H.M. Issaris" Date: Tue, 10 Jan 2012 14:48:57 +0100 Subject: [PATCH 01/36] applehttp: Do seeking within segments, too MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enhance seeking by demuxing until the requested timestamp is reached within the segment selected by the seek code using the playlist info. Some mpegts streams don't have dts set for all packets though, this seeking method doesn't work well for that case.

(commit a95e3fa90b4190381b65d180eec5a4027075e2da) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit 9d03cb9fc5ddf914920ab0dbe13f19a34c754966).
