Justin Ruggles	0354fb7ebe	dpcm: use smaller data types for static tables	14 years ago
Justin Ruggles	5a54d51017	dpcm: use sol_table_16 directly instead of through the DPCMContext.	14 years ago

Justin Ruggles	1de8401c56	dpcm: remove unnecessary variable by using bytestream functions. Uses 'buf' directly instead of a separate iterator variable 'in'.	14 years ago

Justin Ruggles	989bb7bd04	dpcm: consistently use the variable name 'n' for the next input byte.	14 years ago
Justin Ruggles	04b24cf94b	dpcm: output AV_SAMPLE_FMT_U8 for Sol DPCM subcodecs 1 and 2. Uses the native sample format for the codec instead of left-shifting all samples by 8.	14 years ago

Carl Eugen Hoyos	bcb1555489	dxva2_h264: pass the correct 8x8 scaling lists Copy the Inter 8x8 scaling list as second 8x8 matrix into DXVA2's quantization matrix data structure instead of a potentially unset Intra chroma scaling matrix. Fix dxva2 decoding for some H264 samples. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	14 years ago
Mans Rullgard	bf5d46d8e6	dca: NEON optimised high freq VQ decoding Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	6326afd5e9	avcodec: reject audio packets with NULL data and non-zero size There is no valid reason the user should ever send such packets in the first place, but the documentation for CODEC_CAP_DELAY states that the codec is guaranteed not to get a NULL packet unless that capability is set. That isn't true without preventing this case.	14 years ago
Joakim Plate	dcce09d64b	dxva: Add ability to enable workaround for older ATI cards The workaround needs to be enabled per PCI ID which cannot be detected inside libavcodec. So add a flag to manually enable the alternate behavior. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	14 years ago
Justin Ruggles	e562fbd003	adpcm: move codec-specific variable declarations to the sections for the corresponding codecs.	14 years ago
Justin Ruggles	9662539c10	adpcm: check buffer size in Funcom ISS decoder before reading header. Also use the post-header data size to control termination of the main decoding loop.	14 years ago
Justin Ruggles	ba5d2890d7	adpcm: simplify reading of Funcom ISS frame header.	14 years ago
Justin Ruggles	5c9eb4fabb	adpcm: check buffer size in IMA DK4 decoder before reading header. Also use the post-header data size to control termination of the main decoding loop.	14 years ago
Justin Ruggles	a57ea1a87e	adpcm: simplify reading of IMA DK4 frame header.	14 years ago
Justin Ruggles	8114f94ac9	adpcm_ms: clean up reading of predictor coefficients	14 years ago
Justin Ruggles	943f4db552	adpcm_4xm: process planar packets sequentially rather than simultaneously. Also properly clip the right channel step_index.	14 years ago
Justin Ruggles	119974b164	adpcm_ima_wav: process channel-interleaved blocks sequentially rather than simultaneously. Speeds up the ADPCM IMA WAV decoder by 15-20% overall.	14 years ago
Justin Ruggles	7c287b18a0	adpcm: update reference links Add Multimedia Wiki link. Mark dead links with [dead]. Some can still be accessed through archive.org. Update URLs for pages which have moved. Replace duplicated links in adpcmenc.c with a note to see the ADPCM decoder reference documents.	14 years ago
Justin Ruggles	ac94b8bcc6	adpcm: simplify packet size bounds checking in the ADPCM IMA QT decoder. This is easier to understand. It also avoids returning existing samples mixed with new samples when the packet is too small.	14 years ago
Justin Ruggles	de0b586a87	adpcm: simplify and speed up several ADPCM decoders.	14 years ago
Justin Ruggles	5a9ed7c110	adpcm: pretty-print tables	14 years ago
Alex Converse	fcbe421cee	prores: Handle 0 or fewer bits left show_bits() is undefined when the number of bits is less than or equal to zero.	14 years ago
Mans Rullgard	bf00a73ace	dca: clear inactive subbands only once in qmf_32_subbands() Writing zeros to the high entries in the array need only be done once as the cutoff position is constant throughout the loop. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	baf6b738f2	ARM: NEON optimised vector_fmac_scalar() Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	a92a1b93b4	dca: use vector_fmac_scalar from dsputil Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	fcca826a63	dsputil: add vector_fmac_scalar() Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	3d371f417e	ws_snd: misc cosmetic clean-ups	14 years ago
Justin Ruggles	659c719bc7	ws_snd: remove the 2-bit ADPCM table and just subtract 2 instead.	14 years ago
Justin Ruggles	618b067d21	ws_snd: use memcpy() and memset() instead of loops	14 years ago
Justin Ruggles	6896aa7a38	ws_snd: use samples pointer for loop termination instead of a separate iterator variable.	14 years ago
Justin Ruggles	6a818cb3ff	ws_snd: make sure number of channels is 1	14 years ago
Justin Ruggles	417364ce1f	ws_snd: add some checks to prevent buffer overread or overwrite.	14 years ago
Justin Ruggles	2322ced8da	ws_snd: decode to AV_SAMPLE_FMT_U8 instead of S16. 8-bit unsigned is the native sample format.	14 years ago
Justin Ruggles	4c5e7b27d5	flacdec: fix buffer size checking in get_metadata_size() Adds an additional check before reading the next block header and avoids a potential integer overflow when checking the metadata size against the remaining buffer size.	14 years ago
Nicolas George	4ca59d1948	oggdec: add support for Xiph's CELT codec This patch also introduces CODEC_ID_CELT. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Justin Ruggles	88f908fbdc	cosmetics: reindent and pretty-print	14 years ago
Justin Ruggles	8febd6afbc	libgsm: split init and close fuctions for encoder and decoder. The decoder shouldn't be allocating coded_frame. It's also cleaner to split them than to check avctx->codec->encode and avctx->codec->decode.	14 years ago
Mans Rullgard	6e4a35ced9	ppc: fix 32-bit PIC build On 32-bit ppc, the GOT pointer must be loaded manually. This adds a "get_got" assembler macro to compute the GOT address. The "movrel" macro is updated to take an additional parameter containing the GOT address since no register is reserved for this purpose on ppc32. These changes have no effect on ppc64 builds. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	4568c2bf97	vmdaudio: fix decoding of 16-bit audio format. The initial sample of each block is raw 16-bit PCM, not DPCM. Fixes decoding of all samples in: http://streams.videolan.org/samples/game-formats/sierra-vmd/Lighthouse/	14 years ago
