Kostya Shishkov	f399e406af	altivec: perform an explicit unaligned load Implicit vector loads on POWER7 hardware can use the VSX instruction set instead of classic Altivec/VMX. Let's force a VMX load in this case. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Luca Barbato	62cc7a9108	rtjpeg: return meaningful error codes	12 years ago
Luca Barbato	2df0776c22	nuv: Use av_fast_realloc The decompressed buffer can be used after codec_reinit, so it must be preserved. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Luca Barbato	feaaf5f7f0	nuv: Reset the frame on resize Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago

Luca Barbato	aae159a7cc	nuv: Do not ignore lzo decompression failures Update the fate reference since the last broken frame is not decoded anymore. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago

Martin Storsjö	e743e7ae6e	libavutil: Make avpriv_open a library-internal function on msvcrt Add one copy of the function into each of the libraries, similarly to what we do for log2_tab. When using static libs, only one copy of the file_open.o object file gets included, while when using shared libraries, each of them get a copy of its own. This fixes DLL builds with a statically linked C runtime, where each DLL effectively has got its own instance of the C runtime, where file descriptors can't be shared across runtimes. On systems not using msvcrt, the function is not duplicated. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ben Avison	45e10e5c8d	arm: Add assembly version of h264_find_start_code_candidate Before After Mean StdDev Mean StdDev Change This function 508.8 23.4 185.4 9.0 +174.4% Overall 3068.5 31.7 2752.1 29.4 +11.5% In combination with the preceding patch: Before After Mean StdDev Mean StdDev Change Overall 2925.6 26.2 2752.1 29.4 +6.3% Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ben Avison	218d6844b3	h264dsp: Factorize code into a new function, h264_find_start_code_candidate This performs the start code search which was previously part of h264_find_frame_end() - the most CPU intensive part of the function. By itself, this results in a performance regression: Before After Mean StdDev Mean StdDev Change Overall time 2925.6 26.2 3068.5 31.7 -4.7% but this can more than be made up for by platform-optimised implementations of the function. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ben Avison	7a82022ee2	h264_parser: Initialize the h264dsp context in the parser as well Each AVStream struct for an H.264 elementary stream actually has two copies of the H264DSPContext struct (and in fact all the other members of H264Context as well): ((H264Context ) ((AVStream )st)->codec->priv_data)->h264dsp ((H264Context ) ((AVStream )st)->parser->priv_data)->h264dsp but only the first of these was actually being initialised. This prevented the addition of platform-specific implementations of parser-related functions. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Kostya Shishkov	f544c58636	deprecate AV_CODEC_ID_VOXWARE and introduce AV_CODEC_ID_METASOUND instead Voxware is the name of company, it has produced several audio codecs e.g. MetaVoice family and MetaSound.	12 years ago

Diego Biurrun	0ba4ea312b	avcodec/options: Drop deprecation warning suppression macros The options table is used in tools built by the host compiler and the deprecation macros pull in bits that are not safe to use if host and target compiler differ.	12 years ago

Kostya Shishkov	bc909626b0	twinvq: move all bitstream reading into single place This is required for the future addition of VoxWare MetaSound decoder, for its functions are mostly the same but bitstream reader is completely different and bitstream format is slightly different too. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago
Ben Avison	a22ae9f0c5	mpegts: Remove one 64-bit integer modulus operation per packet The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms. Before After Mean StdDev Mean StdDev Change Divisions 248.3 8.8 51.5 7.4 +381.7% Overall 2773.2 25.6 2372.5 43.1 +16.9% Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Rémi Denis-Courmont	f824535a4a	vdpau: deprecate bitstream buffers within the hardware context The bitstream buffers are now private and freed by libavcodec. For backward compatibility, the hold bitstream buffer pointer is left NULL (applications were supposed to av_freep() it). Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
