Diego Biurrun	f61bece684	ppc: Add and use convenience macro to check for AltiVec availability	12 years ago
Rafaël Carré	91d4cfb812	apedec: do not buffer decoded samples over AVPackets Only consume an AVPacket when all the samples have been read. When the rate of samples output is limited (by the default value of max_samples), consuming the first packet immediately will cause timing problems: - The first packet with PTS 0 will output 4608 samples and be consumed entirely - The second packet with PTS 64 will output the remaining samples (typically, a lot, that's why max_samples exist) until the decoded samples of the first packet have been exhausted, at which point the samples of the second packet will be decoded and output when av_decode_frame is called with the next packet). That means there's a PTS jump since the first packet is 'decoded' immediately, which can be seen with avplay or mplayer: the timing jumps immediately to 6.2s (which is the size of a packet).

Kostya Shishkov	4eb4bb3a02	imc: support mode 1	12 years ago
Kostya Shishkov	9e7b62f0fb	twinvq: set block align for codecs and use it in size checks This both allows factoring out size check for both MetaSound and TwinVQ-VQF decoders and fixes the situation when there are several MetaSound frames stuffed together (that happens in 8kHz @ 8kbps MetaSound in ASF for example).	12 years ago
Diego Biurrun	ff9d57e7df	h264_cabac: Mark functions calling decode_cabac_residual_internal as noinline This ensures that decode_cabac_residual_internal actually does get inlined, which it otherwise does not, even though it is marked as always_inline.	12 years ago
Diego Biurrun	f407856968	arm: h264chroma: Do not compile h264_chroma_mc* dependent on h264 decoder The functions are used by all codecs that enable the h264chroma component and the file is already compiled conditional on h264chroma being enabled.	12 years ago
Diego Biurrun	84784c297f	libfdk-aacdec: formatting cosmetics	12 years ago
Diego Biurrun	8506ff97c9	vp56: Mark VP6-only optimizations as such. Most of our VP56 optimizations are VP6-only and will stay that way. So avoid compiling them for VP5-only builds.	12 years ago

Janne Grunau	c34a96a5dd	dxa: fix decoding of first I-frame by separating I/P-frame decoding `5ef7c84` broke decoding for the first keyframe due to an unnecessary check for a reference frame. 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
