Mans Rullgard	b6ae086682	dv: simplify bitstream splicing in dv_decode_ac() This is simpler and fixes some overflow checker warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	f7f892e4d5	svq1enc: fix signed multiplication overflow This multiplication can overflow the signed range but not the unsigned. After right-shifting it will thus fit in the signed range again. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Reimar Döffinger	f6afacdb3b	nuv: check per-frame header for validity. Since it contains dimensions parsing an invalid one has rather annoying effects. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Martin Storsjö	f32dfad9dc	swscale: Readd #define _SVID_SOURCE This was removed erroneously in `046f081b46`. This define still is necessary for getting MAP_ANONYMOUS defined on linux/glibc, despite the define reshuffling done in that commit. Without MAP_ANONYMOUS defined, the mprotect calls for setting the generated mmx2 scaler code pages executable are left out, causing crashes if that codepath is chosen. This patch fixes scaling from 192x144 to 320x240 with -sws_flags fast_bilinear, which crashes on linux at the moment. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Mans Rullgard	019dd23657	Fix av_get_channel_layout_string() for positions >31 A value shifted left by >31 needs to have a 64-bit type. As there are no defined channels in this range, the fix is purely theoretical at this point, although it does avoid some invalid shifts triggering the overflow checker.

Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	00a856e3f9	dca: ARMv6 optimised decode_blockcode() This is a hand-tuned version of the code with impossible parts of the FASTDIV function ommitted. 2-5% faster overall on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Janne Grunau	d14d4d982c	aacdec: add more fate tests covering SBR and PS Add all seven test bitstreams of Coding Technologies "aacPlus Decoder Check Package". The streams cover different ways to signal SBR and PS in different formats.	13 years ago
