Laurent Fasnacht	b48a687d3c	Restored parallelism, but it will be done in another way... OpenMP is not very efficient in these kind of dynamic situation	2014-05-07 11:55:56 +02:00
Laurent Fasnacht	0e6f1c99fc	Refactor picture to remove hidden dependency between slice and tiles picture.type -> encoder_state->global->pictype picture.slicetype -> encoder_state->global->slicetype picture.slice_sao_luma_flag -> 1 (was constant) picture.slice_sao_chroma_flag -> 1 (was constant) This may be changed later. For now it's better to avoid having slice related stuff in picture.	2014-05-07 11:55:48 +02:00

Ari Koivula	eaf8835bda	Add some comments and const qualifiers.	2014-05-06 19:20:38 +03:00
Ari Koivula	3910b7989a	Clear old cbf data before recursion in encode_transform_tree. - Because encode_transform_tree also maintains the CBF data and assumes that the CBFs are initially zeroed, calling the function more than once would result in incorrect CBF data.	2014-05-06 19:03:29 +03:00
Ari Koivula	bdc16d2612	Improve cu_info coded block flag data structure a bit. - It works just like the old structure except that the flags are checked with bitmasks instead of having the flag value be propagated upwards. There isn't really any benefit to this because the flags still have to be propagated to parent CUs. - Wrapped them inside a struct to make copying them easier. (Just need to copy the struct instead of making individual copies)	2014-05-06 18:28:04 +03:00
Ari Koivula	d123b98aea	Remove unnecessary tertiary expressions from usages of CABAC_BIN.	2014-05-06 17:39:25 +03:00
Ari Koivula	380401b2eb	Have CABAC_BIN accept any >0 as binary 1. It used to treat odd numbers as false.	2014-05-06 17:39:10 +03:00
Marko Viitanen	bf2c2a1330	Small changes to fix compiling on VS - Added threads.h to VS project - Included Windows.h in threads.h	2014-05-05 11:18:43 +03:00
Laurent Fasnacht	f3d4e6eb09	Move bitstream write to a separate function, and add assertions about the part which should not write to bitstream.	2014-05-05 09:24:57 +02:00

Ari Koivula	42295d3cb9	Pass preprocessor defines for supported intrinsics in VS2010 explicitly. - _M_IX86_FP defines whether VS should generate code using SSE or SSE2 instructions. It isn't correct to use it to check whether optional runtime optimizations should be compiled in. It's also not defined at all in 64-bit mode. - So let's just keep it simple and give a list of everything that is supported as release optimizations. It's not clear from the documentation if all of these are really supported. It just list a bunch of intrinsics from these that are.	2014-04-30 17:41:15 +03:00
Ari Koivula	d1fbc6dc80	Fix a small memory leak. - Malloced pointer returned by alloc_yuv_t was not being freed in substream_encode. - Remove use of yuv_t from encode_one_frame, as it's not used there anymore.	2014-04-30 11:15:34 +03:00
Ari Koivula	d808fe3b02	Merge branch 'strategy_selector'	2014-04-29 15:36:48 +03:00
Ari Koivula	bd7e021742	Modify strategyselector to work with VS2010. - VS doesn't have snprintf. - VS doesn't support GCC attributes. - Add defines for __SSE__ and __SSE2__ on VS.	2014-04-29 15:29:06 +03:00

Ari Koivula	2a17e9a7aa	Merge branch 'sse_intrinsics'	2014-04-28 19:38:08 +03:00
Ari Koivula	cecf4b0b4e	Move __USE_MINGW_ANSI_STDIO to Makefile. - I'm not too clear on how this should be used, but having it in the source file after mingw stuff was included caused a warning about redefinition of __USE_MINGW_ANSI_STDIO.	2014-04-28 19:37:37 +03:00
Ari Koivula	4e7e40054f	Move picture-sse2.c to src/inline-optimizations/. - Having it in the src dir even though it's not a module on it's own breaks the scons build script. It's probably better to have these a little bit separated from the normal code anyway.	2014-04-28 19:36:40 +03:00
Laurent Fasnacht	d66f809734	reg_sad implementation using SSE2/SSE4.1 intrinsics	2014-04-28 15:36:58 +02:00
Ari Koivula	4490e8afd6	Remove depth dimension from picture->cu_array. - It isn't used for anything anymore. - It was used in the past to hold information during search, but now that information is held in lcu_t structs.	2014-04-28 10:18:22 +03:00
Laurent Fasnacht	76ec605b72	SAO works with tiles now	2014-04-28 06:29:21 +02:00

Ari Koivula	a539ae7e08	Address clang-analyzer warning. - The assert needs to be before the initialization.	2014-04-22 11:55:28 +03:00
Laurent Fasnacht	5fea5875a5	Huge refactoring Split some parts of encoder_control into encoder_state (idea: encoder_control is immutable) Goal is to allow multiple substreams in the future.	2014-04-22 10:39:12 +02:00
Ari Koivula	88a67a4e49	Fix faulty assert that stops the program from working with inter frames. - The assert would be true after the next if block, but in it's current place it's false.	2014-04-22 10:57:38 +03:00
Ari Koivula	54270f271d	Fix c89 problem to allow compilation with VS2010.	2014-04-17 19:12:39 +03:00
Ari Koivula	1b437a5989	Address clang-analyzer warnings about garbage values. - False alarm, but surprisingly difficult to convince clang of that. It doesn't seem to understand bit shifts very well. - Only assert and changing LCU_WIDTH>>depth to width was necessary to satisfy clang. - Closes #35.	2014-04-17 18:43:09 +03:00
Ari Koivula	11509c68dc	Address clang-analyzer warnings about unused values. - Related to issue #35.	2014-04-17 18:43:08 +03:00
Ari Koivula	0704c43836	Address clang-analyzer warning about undefined behavior in intra. - Related to issue #35.	2014-04-17 18:43:08 +03:00
Ari Koivula	32da12f653	Address a clang-analyzer warning about undefined behavior in filter. - Analyzer didn't see that code is never called with MAX_DEPTH as it doesn't know the properties of width, height, x and y. Following would also silence the error: assert(cur_pic->width > 0 && cur_pic->height > 0); assert(cur_pic->width % 8 == 8 && cur_pic->height % 8 == 0); assert(x > 0 && y > 0); assert(x % 8 == 0 && y % 8 == 0); - Related to issue #35.	2014-04-17 18:43:08 +03:00

Ari Koivula	51ba80513b	Centralize resource deallocation for encmain. - CppCheck was complaining about unreleased resources for FILE*. They weren't really because they get flushed and closed when program exits normally, but let's close them anyway.	2014-04-17 11:58:03 +03:00
Ari Koivula	b35f33b3da	Address warnings about unused values. - Related to issue #35.	2014-04-16 18:05:03 +03:00
Ari Koivula	9229e5d11b	Fix undefined behavior of EO_IDX. - Move the whole eo_cat thing to it's own function. - Casting pixel values to int should solve issues with SIGN3. Not casting them was detected as undefined behavior by CLANG. Probably because the result of two unsigned might be treated as unsigned (but isn't on VS2010).	2014-04-16 14:50:19 +03:00

Ari Koivula	880d09b27a	Add sao_type_idx to SAO mode cost estimation.	2014-04-15 21:29:09 +03:00
Ari Koivula	280a946269	Apply bit cost fixes to edge band band sao search. - Increases bdrate slightly. It's still a cleaner solution though and further improvements to bit cost estimation might improve things.	2014-04-15 21:28:16 +03:00
Ari Koivula	c968253eb3	Estimate SAO merge coding costs better. - This doesn't seem to have very much of an effect. I guess the difference between 1 and 2 bits isn't that important.	2014-04-15 21:27:16 +03:00
Ari Koivula	ef7840c623	Add SAO coding costs for sao_eo_class, band position and offset sign. - This reduces bdrate a little bit. - It seems like increasing the bit cost of using SAO in general increases bdrate.	2014-04-15 21:24:44 +03:00
Ari Koivula	9ff32c566c	Adjust SAO mode coding cost for zero offsets. - Coding zero with TR only takes one bit. - Even though offset 0 should be fairly common, this doesn't seem to help very much and actually increases bdrate on some sequences.	2014-04-15 21:21:31 +03:00
Ari Koivula	67a3d5542c	Add better delta distortion calculation to sao.	2014-04-15 21:17:29 +03:00

Ari Koivula	c42b25054a	Modify deblocking to be done per-LCU in the encoding loop. - Intra works. There is still something wrong in inter. - Avoid horizontal deblocking of the rightmost 4 pixels in the LCU. This is because vertical deblocking must be done for all pixels before horizontal, but vertical deblocking can't be done for those pixels before the next LCU is finished. - Add separate deblocking of the rightmost pixels of the last LCU after the LCU edge has been deblocked. - This is a pretty ugly hack but will have to do for now.	2014-03-20 18:14:43 +02:00
Ari Koivula	bbd1202f90	Replace old LCU reference pixels initialization with new ones. In the future we might even have just a const pointer to reference pixels.	2014-03-19 16:01:31 +02:00
Ari Koivula	7328fc2897	Add special handling for bottom right LCU pixel. I didn't take into account that the reference pixel on the top-left of the LCU gets over written if we just replace the top reference pixels for current LCU with the bottom reference pixels after doing the search. To handle this I copy the pixel that gets overwritten to the vertical reference pixels.	2014-03-19 16:01:31 +02:00
Ari Koivula	57ce7e990b	Add new reference pixel buffer management to encoding loop. - This is necessary because after we add in-loop filters to be done per LCU, the reconstruction buffer will have the deblocked pixels. We only need the edge-pixels for intra prediction though so we just save those. - Right now it only copies the pixels and passes them on to search, where the copied pixels are asserted to be the same ones we copy from reconstruction buffer. - New yuv_t struct added for arrays of dynamic length. We might want to change other buffers to use it or something like it in the future.	2014-03-19 16:01:30 +02:00
Ari Koivula	eacad83ff9	Fix encoder reconstruction output for non multiple of 8 sized input. Output changed so that only pixels within the conformance window are output.	2014-03-19 13:24:01 +02:00
Ari Koivula	34e453c880	Clean up encode_one_frame. There is a lot of duplicated code due to handling random access and trailing pictures separately. I merged the code for these two branches so it would be easier to modify.	2014-03-17 18:04:41 +02:00
Ari Koivula	b1596eb76c	Refactor coding of end_of_slice_segment_flag. According to spec the end_of_slice_segment_flag is always coded, but in the code it looked like it was not coded for the last LCU in picture. This was due to the end_of_slice_segment_flag being coded inside cabac_flush, like it is in HM. This is a bit silly so I moved it out of cabac_flush.	2014-03-17 18:04:41 +02:00
Ari Koivula	6a384112cc	Remove old unnecessary functions from search module. - As we move to per-LCU encoding only search_lcu will be necessary. - Function search_best_mode is no longer used.	2014-03-17 18:04:41 +02:00
Marko Viitanen	c7ee176480	Removed unused function search_best_mode()	2014-03-17 12:56:04 +02:00
Ari Koivula	9563b50a34	Refactor coefficient group scan mapping lists. The relation between coefficients positions and coefficient group positions was a big confusing due to the use of 16x16 diagonal coefficient mappings also as coefficient group mappings. - Moved all coefficient group mappings to their own const arrays and added a new array the select the correct coefficient group mapping. This removes special cases for 8x8 and 32x32 transform sizes. - Removed all coefficient group mapping initialization from init_sig_last_scan. - Removed 128x128 and 64x64 from regular coefficient group array as those transform sizes don't exist anymore in HEVC.	2014-03-14 16:56:49 +02:00

Marko Viitanen	b5756821dd	Tuned cost calculations for "final cost" By adding chroma cost and using 1.5x coeff cost instead of 0.5x, additional 3% (LP) and 1.8% (AI) drop in BD-rate noticed.	2014-03-12 10:35:56 +02:00
Ari Koivula	409b094acf	Try and get NxN to work again. - Moved NxN search to be done on the same level as other searches, as it's really not any different from 2Nx2N. - Produces working bitstream but reconstruction is different.	2014-03-11 19:19:20 +02:00

Ari Koivula	7e507fd615	Add --input-res CLI parameter. - Also set default width and height to 0 because it makes no sense to assume dimensions. It's kind of like defaulting to the most common altitude when the altimeter is broken. - Add config_validate to have a place for checks on overall cfg state.	2014-03-10 16:09:33 +02:00
Ari Koivula	a644848b36	Add --seek CLI parameter. Related to issue #12. Motivation for adding this is that the syntax for frame accurate seeking in ffmpeg is a little cumbersome. Also it's kind of a standard feature I guess.	2014-03-10 15:14:56 +02:00

Ari Koivula	ca51f660d5	Fix fluctuation of coefficients on identical frames when RDOQ is on. Moves CABAC context initialization to take place before search. This fixes an issue with RDOQ returning different coefficients for identical adjacent frames. - This actually probably worsens BD-rate a little for all frames except the first one because we were using last frames final CABAC context for every LCU and now we are using initialized CABAC contexts. The fix is to encode the LCU before we start compressing the next LCU so we can update CABAC contexts.	2014-03-05 17:02:13 +02:00

Ari Koivula	7bb9c25447	Remove duplicate implementation of intra_build_reference_border. The search_buildReferenceBorder was an ugly hack and a place for bugs to hide that should never have existed. Now it doesn't. The change reduces PSNR a little, but also reduces the bitrate, when the expected result was to have no change in either. I'm guessing there was still some bug in the search_buildReferenceBorder, but the bug could also be in intra_build_reference_border. Will have to do more testing to be sure, but having one place to look at will be better than having two.	2014-02-03 18:35:11 +02:00

Marko Viitanen	ac8141b328	Fixed a bug in intra search and some memory leaks, changed version to 0.2.1 Intra search was using faulty border data and selected modes were a bit random. Around -0.5% (LP) and -2% (AI) change in BD-rate was seen in limited testing conditions.	2014-01-31 16:54:43 +02:00
Jan Ekström	f1ff6a8274	encmain: Add rudimentary support for input via stdin	2014-01-31 14:32:41 +02:00

Marko Viitanen	76f24408b6	Included x264asm abstraction layer -library and fixed Makefile Name mangling is causing problems on different platforms (issues #2 and #3) and some of it was solved modifying the Makefile. Separate 32bit and 64bit assembly functions were also causing problems and since we were going to move to x264asm abstraction layer anyway, we decided to do it now before spending time on the old implementation.	2014-01-30 17:59:50 +02:00
Ari Koivula	b93629f26e	Re-enable P frames. It was inadvertently disabled due to an aborted merge.	2014-01-29 17:56:38 +02:00
Gareth Andrew Lloyd	3805483595	Linker's objects/libraries order changed gcc linker needs to parse objects before linking the necessary libraries	2014-01-29 15:34:31 +00:00
Ari Koivula	5d12706510	Merge branch 'intra_NxN' Conflicts: src/encoder.c - Chroma RDOQ changes conflicted because I had moved the chroma quantization/dequantization to it's own function. - Merged to master because I want my code to show up in github. =) All the old stuff still works, even though NxN doesn't work, so there is no reason not to merge anyway.	2014-01-29 17:04:41 +02:00
Ari Koivula	e33655fde5	Remove debug stuff and disable intra NxN in preparation for a merge. - Re-enable intra search based on reconstructed image. - This didn't have as much of an effect as I thought it would. - Re-enable SAO and deblocking. - Disable NxN searching. (4x4 luma coding is still broken)	2014-01-29 16:45:37 +02:00
Ari Koivula	bf80007270	Try to fix 4x4 luma coding. Still doesn't work. I have no idea what the problem is. Probably somehow related to the coefficient coding, since the bitstream seems to work, the prediction is correct and the error is not very severe. - Change scan order selection to be more verbose and based on the correct mode for 4x4. Didn't affect the problem with 4x4 luma in any way although it should have. - Re-enable residual coding as everything seems to work now besides 4x4 luma.	2014-01-29 15:09:41 +02:00
Ari Koivula	de3c58862a	Fix intra NxN chroma coefficients. - The NxN coefficients were being saved to the bottom right PU offset instead of the parent CU offset. - Re-enable coefficient coding for chroma NxN.	2014-01-29 14:22:31 +02:00
Ari Koivula	f1b2e9f603	Fix buggy chroma when NxN is present. - NxN intra prediction seems to work fully now. - Coefficients still don't work for NxN.	2014-01-29 14:22:31 +02:00
Ari Koivula	9f855c16db	Fix building of reference border in the bottom of the frame. - Don't write to the top-left corner during construction of left border, because that is handled later that is handled later.	2014-01-29 14:22:31 +02:00

Ari Koivula	81b51f17d8	Reimplement intra_build_reference_border to support NxN. New implementation uses precalculated tables to look up number of reference pixels available in coded CUs. Otherwise it works just like the previous version. - NxN mostly works. Prediction appears to be almost correct but there is a slight error in the exact values, probably related to filtering.	2014-01-29 14:22:30 +02:00
Ari Koivula	71a996f50f	Work on reconstruction and searching. - Set part-size for Inter. - Change to Intra Only mode for testing. - Many small changes here and there. Should have been separate commits probably, but too late. - Disable SAO and deblocking to be able to see problems with reconstruction better.	2014-01-29 14:18:01 +02:00
Ari Koivula	5e2f22f447	Try to fix intra prediction mode coding for NxN. - Adjust predictor list to take modes from PUs in addition to 2Nx2N CUs. - Change intra_get_dir_luma_predictor to take PU index instead of CU index. - Comment prediction encoding now that I've had to look it up.	2014-01-29 13:52:17 +02:00

Ari Koivula	a38a5fd647	Improve transform tree coding. - Clean up code and comment. - Change terminology to match H.265 specification where possible. - Move transform splitting for depth==0 out of the coding part. It's not possible to do it here anyway because intra reconstruction is different if the transform is split. - Add checking for transform hierarchy depth when coding split flag. - Fixes bug with cu_data.tr_depth being set. The CU struct was being reused for inter coded CUs, which did not initialize the tr_depth.	2014-01-14 18:39:24 +02:00
Ari Koivula	d5745aa31a	Fix encode_transform_tree to handle 4x4 luma. - Add room to cu_data.coeff_top_yuv arrays for the 4x4 PUs data. Will probably have to do the same to other coeff flags. The flags could also probably be combined as they are a bit redundant.	2014-01-13 18:37:47 +02:00
Ari Koivula	73fdc35c4f	Try to implement 4x4 luma transform coding. - Doesn't work yet so it's disabled. - Change encode_transform_coeff to accept PU (Prediction Unit) coordinates instead of CU coordinates because CUs are 8x8.	2014-01-09 19:30:54 +02:00

Ari Koivula	553bcdc324	Rewrite intra prediction mode coding to be simpler. Should work exactly the same, but with the prediction mode selection done separately from the binarization it's easier to see that the implementation is correct.	2013-12-18 14:16:04 +02:00
Ari Koivula	cf0d314d03	Clean up prediction mode coding. This was done as preparation for adding NxN intra. - Monochrome coding was removed as it's not part of the standard. - No other functional changes.	2013-12-18 11:25:44 +02:00

Ari Koivula	7bd0902727	Implement fast distortion estimation for sao. Add function for blitting pixels from one buffer to another. Several commits have been squashed to this one.	2013-11-04 12:37:37 +02:00
