Ronald S. Bultje	46b3fbc30b	golomb: use HAVE_BITS_REMAINING() macro to prevent infloop on EOF. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	b44b41633f	get_bits: add HAVE_BITS_REMAINING macro.	13 years ago
Alex Converse	447363870f	tiff: Prevent overreads in the type_sizes array. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Alex Converse	e32548d133	tiff: Make the TIFF_LONG and TIFF_SHORT types unsigned. TIFF v6.0 (unimplemented) adds signed equivalents.	13 years ago
Christophe GISQUET	2784d18791	SBR DSP x86: implement SSE sbr_hf_g_filt Unrolling the main loop to process, instead of 4 elements: - 8: minor gain of 2 cycles (not worth the extra object size) - 2: loss of 8 cycles. Assigning STEP to a register is a loss. Output address (Y) is almost always unaligned. Timings: - C (32/64 bits): 117/109 cycles - SSE: 57 cycles Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	34454c761f	SBR DSP x86: implement SSE sbr_sum_square_sse The 32bits targets have been compiled with -mfpmath=sse for proper reference. sbr_sum_square C /32bits: 82c (unrolled)/102c C /64bits: 69c (unrolled)/82c SSE/32bits: 42c SSE/64bits: 31c Use of SSE4.1 dpps to perform the final sum is slower. Not unrolling to perform 8 operations in a loop yields 10 more cycles. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	2e74a5abc2	SBR DSP: use intptr_t for the ixh parameter. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Derek Buitenhuis	480b133e6f	wavpack: Don't shift minclip/maxclip Since we are clipping before we shift the values to 16 or 32 bits, we should not shift the min/max clip values to compensate. Fixes 8 and 24 bit lossy decoding. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Anton Khirnov	ff311c0918	lavc: drop encode() support for video. All video encoders have been converted to encode2(), all new encoders should also use only encode2().	13 years ago
Anton Khirnov	171273fec8	snowenc: switch to encode2().	13 years ago
Anton Khirnov	8d3348c2c4	snowenc: don't abuse input picture for storing information.	13 years ago
Anton Khirnov	7340008f18	a64multienc: switch to encode2(). We have no decoder, so cannot test if the output is decodable.	13 years ago
Anton Khirnov	cfc6ab3199	a64multienc: don't write into output buffer when there's no output.	13 years ago
Anton Khirnov	4da6d194e5	libxvid: switch to encode2().	13 years ago
Anton Khirnov	760b004086	tiffenc: switch to encode2().	13 years ago
Anton Khirnov	62acb4937e	tiffenc: properly forward error codes in encode_frame().	13 years ago
Anton Khirnov	2257f66ec5	lavc: drop libdirac encoder. Libschroedinger is the preferred way to encode dirac video now, it produces better output and has a nicer API.	13 years ago
Anton Khirnov	577fed3b7c	gifenc: switch to encode2().	13 years ago
Anton Khirnov	d8f3365fb0	libvpxenc: switch to encode2().	13 years ago
Anton Khirnov	0ecf54f9dc	flashsvenc: switch to encode2().	13 years ago
Ronald S. Bultje	01cb62aba2	lcl: don't overwrite input memory. If the PNG filter is enabled, a PNG-style filter will run over the input buffer, writing into the buffer. Therefore, if no zlib compression was used, ensure that we copy into a temporary buffer, otherwise we overwrite user-provided input data.	13 years ago
Anton Khirnov	84db922bf9	libxavs: switch to encode2().	13 years ago
Anton Khirnov	d3b577f00d	libxavs: add an AVClass at the beginning of XavsContext.	13 years ago
Anton Khirnov	a5f848c86d	libxavs: split extradata writing out of encode_nals(). This is done in preparation for the following patch implementing encode2(). This commit is analogous to `05d699222d` for libx264.	13 years ago
Anton Khirnov	8e8124e173	ljpegenc: switch to encode2().	13 years ago
Ronald S. Bultje	2b83e8b700	truemotion2: error out if the huffman tree has no nodes. This prevents crashers and errors further down when reading nodes in the empty tree. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Christophe GISQUET	b5696ff2b8	prores: use natural integer type for the codebook index The operations that use it require it to be promoted to a larger (natural) type and thus perform sign extension on it. While an optimal compiler may account for this, gcc 4.6 (for x86 Windows) fails. Using the natural integer type provides a 2% speedup for Win64 and 1% for Win32.

Justin Ruggles	70749c483c	avcodec: do not override pts or duration from the audio encoder This allows encoders to set pts and/or duration even if they do not use CODEC_CAP_DELAY.	13 years ago

Ronald S. Bultje	3ab9a2a557	rv34: change most "int stride" into "ptrdiff_t stride". This prevents having to sign-extend on 64-bit systems with 32-bit ints, such as x86-64. Also fixes crashes on systems where we don't do it and arguments are not in registers, such as Win64 for all weight functions.	13 years ago
Justin Ruggles	770a5c6d02	adpcmenc: Use correct frame_size for Yamaha ADPCM. Output packet size should match avctx->block_align. The target output packet size is 1024 bytes. Before: mono - 1024 samples -> 512 bytes stereo - 2048 samples -> 2048 bytes After: mono - 2048 samples -> 1024 bytes stereo - 1024 samples -> 1024 bytes	13 years ago
