Tim Walker	0d43b114cc	eac3: cosmetics, re-indent.	11 years ago
Tim Walker	ade75fb811	(e)ac3: clip surround mix level indexes. Values 0-2 are reserved, 3 (-1.5dB) should be used instead.	11 years ago
Tim Walker	c229f571fd	(e)ac3: parse and store the Lt/Rt and LFE mix levels.	11 years ago
Tim Walker	1f604f96ea	ac3: set default matrix encoding modes in parse_frame_header. Deduplicates some code.	11 years ago
Anton Khirnov	8b2e5e42bb	h264: check that an IDR NAL only contains I slices Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	9ecabd7892	h264: reset num_reorder_frames if it is invalid An invalid VUI is not considered a fatal error, so the SPS containing it may still be used. Leaving an invalid value of num_reorder_frames there can result in writing over the bounds of H264Context.delayed_pic. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	0652e024c6	h264: reset ref count if decoding the slice header fails Otherwise the ER code might try to use some already freed references. Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	98cc9efc5f	h264: prevent two matching fields from being both a short/long ref combination Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	00dbff4c3e	h264: do not call field_end if we do not have a current picture Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	7f0e81db3c	h264: limit allowed pred modes in ff_h264_check_intra_pred_mode() to 3 Higher modes are not allowed for 16x16/chroma, which is what this function is used for. Otherwise this function would return 0 (vertical prediction) for invalid higher modes, which could result in invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	d1b3fabe69	h264: reset first_field if frame_start() fails for missing refs In this case we may not have a current frame, while first_field being set implies we do. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago

Janne Grunau	71617884a2	aarch64: h264 chroma motion compensation NEON optimizations Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.	11 years ago
Janne Grunau	1e9265cd8f	dct-test: test ff_simple_idct_neon only on ARM for now Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Janne Grunau	8b4119187b	cabac: remove leftovers from the cabac encoder The cabac encoder was only used by the removed cabac test. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago

Martin Storsjö	44a0a98f92	arm: Add an option for making sure NEON registers aren't clobbered This is pretty much based on the same test for XMM registers. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Diego Biurrun	4b48201d4d	ac3tab.h: #include the correct headers	11 years ago
Anton Khirnov	d48132b7de	mjpegdec: apply flipping after decoding, not before This is simpler and removes a silly restriction on edges being present.	11 years ago
Guillaume Martres	e588615d93	hevc: fix decoding of one PU wide files For those the block size may be larger than the source linesize (if the edges are not allocated). Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Anton Khirnov	ca96e33716	vp9: drop support for real (non-emulated) edges They are not measurably faster on x86, they might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough to justify the added complexity.	11 years ago
Anton Khirnov	ef8c93e2f1	vp8: drop support for real (non-emulated) edges They are not measurably faster on x86, they might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough to justify the added complexity.	11 years ago
Anton Khirnov	ebfe622bb1	mpegvideo: drop support for real (non-emulated) edges Several decoders disable those anyway and they are not measurably faster on x86. They might be somewhat faster on other platforms due to missing emu edge SIMD, but the gain is not large enough (and those decoders relevant enough) to justify the added complexity.	11 years ago
Martin Storsjö	952d3187d8	arm: Add a missing # as prefix for an immediate constant Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	5dae487235	arm: Allow overriding the alignment set in the function macro The function macro always sets .align 2 before declaring the function label (since `5c5e1ea3`) and always sets the section to .text (since `278caa6a`). The .align 5 before certain functions, added in `fc252eba`, were added before .text and .align were added to the function macro and thus became useless/unused when the function macro got them. This restores the original intention, to align the loop entry points. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	b7b932f5e3	arm: Remove a leftover define for the pld instruction This file no longer uses the pld instruction at all, all such uses have been split into hpeldsp_arm.S. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	67bb3a4e28	arm: cosmetics: Reindent the h264dsp neon init function Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Diego Biurrun	794fcf79a8	Rename CONFIG_FFT_FLOAT ---> FFT_FLOAT The define does not originate from configure, so it should not have a name that is CONFIG_-prefixed.	11 years ago
Paul B Mahol	63debaa74c	libopusenc: Change default frame duration to 20 ms 20 ms is the default in the libopus encoder, and gives better quality than 10 ms. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Anton Khirnov	9cbf2d78f0	pthread_frame: unref decoded frames on failure This is similar to what the non-threaded code already does. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	a03a642d5c	h264: do not use 422 functions for monochrome Fixes invalid memory access. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	9eef9eb301	h264: check that execute_decode_slices() is not called too many times Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	bfd26b7ce6	h264: reject mismatching luma/chroma bit depths during sps parsing There is no point in delaying the check and it avoids bugs with a half-initialized context. Fixes invalid reads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
Anton Khirnov	9a026c7298	h264: rebuild the default ref list if the reference count changes Fixes possible access to freed memory. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago
