From 2d31d890bfce103512dca34e35815762eb61b5da Mon Sep 17 00:00:00 2001 From: Martin Storsjö Date: Wed, 30 Nov 2011 22:03:43 +0200 Subject: rtpenc: Cast a rescaling parameter to int64_t MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This avoids overflow if frame_size is over 2147, since both frame_size and AV_TIME_BASE are plain integers.
