Tim Walker	149438cfe5	dca: improve default stereo downmix coefficients. Previous coefficients were producing a non-normalized, incorrect Lt/Rt downmix. The new coefficients produce a standard Lo/Ro downmix with 3dB attenuation. This should match the typical default coefficients used by DTS encoders. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	44b17d794a	dca: extract core substream's embedded downmix coeffcient codes, if present. As per ETSI TS 102 114 V1.4.1 specification. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	27245b4e1b	dca: remove embedded downmix coefficient extraction. It was based on an old, seemingly incorrect specification, so default coefficients were always used anyway. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	b6d5e6aa10	dca: convert dca_default_coeffs to float. Easier to read, modify, and avoids relying on an outdated table. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Tim Walker	25609b63d2	dcadec: store the stereo downmix coefficients as float in the DCAContext. The 7-bit codes previously used are absent from the ETSI 102 114 V1.4.1 spec. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Vittorio Giovara	0673ede985	configure: add strip flags checks This will check if -wN '..@*' is available and fall back on -x if not; when none are available, do not run strip at all to prevent removing functions that might be actually needed.	11 years ago
Anton Khirnov	8733799392	h263dec: sanitize a condition. Call ff_mpeg4_decode_picture_header() only when the decoder has the MPEG4 codec id, not based on a vaguely related value of h263_pred.	11 years ago
Anton Khirnov	4d388c0cd0	h264_refs: make sure not to write over the bounds of the default ref list Fixes invalid writes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	11 years ago

Martin Storsjö	dc80e2f7a5	Makefile: Fix building programs on systems with a nonempty executable suffix This fixes leftover issues from `14abeaa4` which caused make rules for programs to not match up properly when the executable suffix was nonempty. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Anton Khirnov	c6080d8900	lavc: remove mp3_header_(de)compress bitstream filters They mangle the mp3 header in a non-standard way to save a few bytes. People who care about space so much should just use a more efficient codec.	11 years ago
