Michael Niedermayer	9f50d3b944	avcodec/rv34: Fix () in GET_PTS_DIFF() macro Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
wm4	f6774f905f	mpegvideo: operate with pointers to AVFrames instead of whole structs The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	11 years ago
Vittorio Giovara	e0c16e4e32	mpegvideo: move mpegvideo formats-related defines to mpegutils.h	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
Michael Niedermayer	ea1e630c47	vcodec/rv34: use av_mallocz() to allocate tables Fixes use of uninitialized memory Fixes: msan_uninit-mem_7f75e2a55b88_4146_brokenaudio.rmvb Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Anton Khirnov	1d389e2a80	rv34: stop using deprecated avcodec_set_dimensions	11 years ago
Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago

Diego Biurrun	82bd04b170	rv34: Drop now unnecessary dsputil dependencies	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Ronald S. Bultje	8c53d39e7f	lavc: introduce VideoDSPContext Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch().

Clément Bœsch	8b63744f48	Fix "bistream" typo and add a check in tools/patcheck.	12 years ago

Janne Grunau	b16d001b62	rv34: use ff_MPV_common_frame_size_change() Specialised functionality for size changes with the advantage of supporting frame size changes during frame-based multithreading.	12 years ago

Ronald S. Bultje	774b681b80	rv34: remove inline keyword from rv34_decode_block(). Force-inlining increases object size by 8kB and causes a 2% slowdown.	13 years ago
Christophe Gisquet	0195ab5f5f	rv40: change a logical test into a bitwise one. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe Gisquet	8802799991	rv34: remove constant parameter is_block2 was always 0, so just remove it, and change accordingly the code. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	272b252c01	rv40dsp: implement prescaled versions for biweight. Quite often, the original weights are multiple of 512. By prescaling them by 1/512 when they are computed (once per frame), no intermediate shifting is needed, and no prescaling on each call either. The x86 code already used that trick.

Michael Niedermayer	2d0b4bc4cf	rv34: Fix check_slice_end() handling of 0 bits left case Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Diego Biurrun	a92be9b856	Replace memset(0) by zero initializations. Also remove one pointless zero initialization in rangecoder.c.	13 years ago
Ronald S. Bultje	5484170ac7	rv34: set mb_num_left to 0 after finishing a frame Prevents running error resilience on a previous frame which will write to the pic->mb_type[] array of the previous image. The array might already be re-used for a new image in a subsequent thread, thus cause two threads to write to the same pic->mb_type[] array, causing a race condition which can crash in rv34_decode_cbp(), called by rv34_decode_inter_mb_header() (which accesses mb_type[] twice, assuming values are maintained, which the race condition breaks).

Janne Grunau	cb7190cd2c	rv34: error out on size changes with frame threading	13 years ago
Janne Grunau	73ad4471a4	rv34: Handle only complete frames in frame-mt. Correct handling of errors to prevent hags or crashes is very complex otherwise. The frame initializing is also moved from decode_slice() to decode_frame() for clarity.	13 years ago
Christophe GISQUET	294c05ce8a	rv34: remove dead code in intra availability check This was an incorrect copy-and-paste to a code not needing the original code. Spotted by Jason in a previous review but forgotten in the commit. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	7104c23bd1	rv34: clean a bit availability checks. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Janne Grunau	2bd730010d	rv34: handle size changes during frame multithreading Factors all context dynamic memory handling to its own functions. Fixes bug 220.	13 years ago
Janne Grunau	29330721b0	rv34: use AVERROR return values in ff_rv34_decode_frame() Also adds an error message.	13 years ago
Christophe GISQUET	9ba9c34024	rv34: 1-pass inter MB reconstruction Implement 1-pass inverse transform and reconstruction for inter blocks.	13 years ago
Christophe GISQUET	d78062386e	rv34: Intra 16x16 handling Extract processing of intra 16x16 blocks from intra macroblock processing. Also implement a function performing inverse transform and block reconstruction for DC-only blocks in 1 pass instead of 2.	13 years ago
Christophe GISQUET	3eeb755763	rv34: Inter/intra MB code split Split inter/intra macroblock handling code. This will allow further optimizations such as performing inverse transform and block reconstruction in a single pass as well as specialize code. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Janne Grunau	3547f8e8f8	rv34: fix and optimise frame dependency checking The sporadic threading errors during fate-rv30 were caused by calling ff_thread_await_progress with mb row -1 as argument. That returns immediately since progress is initialized to -1. Not yet computed motion vectors from the reference could be used for the first macroblocks.	13 years ago
Christophe GISQUET	3faa303a47	rv34: DC-only inverse transform When decoding coefficients, detect whether the block is DC-only, and take advantage of this knowledge to perform DC-only inverse transform. This is achieved by: - first, changing the 108x4 element modulo_three_table into a 108 element table (kind of base4), and accessing each value using mask and shifts. - then, checking low bits for 0 (as they represent the presence of higher frequency coefficients) Also provide x86 SIMD code for the DC-only inverse transform.
