From 8df8a9299364016027825a67534b93cd2b6af473 Mon Sep 17 00:00:00 2001 From: Hendrik Leppkes Date: Thu, 5 Apr 2018 17:09:35 +0200 Subject: avcodec/aac_ac3_parser: account for data already in the parsing buffer If a frame starts very close to a packet boundary, the start code may already have been added to the parsing buffer, indicated by a small negative value of "i", while the header is still being tracked in the "state" variable. Reduce the remaining size accordingly, otherwise trying to find the next frame could skip over the frame header and lump two frames together as one. --- libavcodec/aac_ac3_parser.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'libavcodec/aac_ac3_parser.c') diff --git a/libavcodec/aac_ac3_parser.c b/libavcodec/aac_ac3_parser.c index 019074b0dd..54e459844f 100644 --- a/libavcodec/aac_ac3_parser.c +++ b/libavcodec/aac_ac3_parser.c @@ -60,6 +60,9 @@ get_next: s->remaining_size += i; goto get_next; } + else if (i < 0) { + s->remaining_size += i; + } } } } -- cgit v1.2.3
