Vittorio Giovara	67fc8a15e4	theora: support different visible and coded frame size Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Anton Khirnov	7ea1b3472a	lavc: deprecate the use of AVCodecContext.time_base for decoding When decoding, this field holds the inverse of the framerate that can be written in the headers for some codecs. Using a field called 'time_base' for this is very misleading, as there are no timestamps associated with it. Furthermore, this field is used for a very different purpose during encoding. Add a new field, called 'framerate', to replace the use of time_base for decoding.	10 years ago
Gabriel Dume	f929ab0569	cosmetics: Write NULL pointer equality checks more compactly Signed-off-by: Diego Biurrun <diego@biurrun.de>	10 years ago
Justin Ruggles	9e500efdbe	Add av_image_check_sar() and use it to validate SAR	11 years ago
Vittorio Giovara	d2264740e6	VP3: K&R formatting cosmetics	11 years ago
Diego Biurrun	f9279ee749	dsputil: Move ff_zigzag_direct and ff_crop_tab declarations to mathops.h	11 years ago
Diego Biurrun	f2408ec9d7	Give IDCT matrix transpose macro a more descriptive name This also avoids a macro name clash and related warning on ARM.	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	b53febc1c0	vp3: stop using deprecated avcodec_set_dimensions	11 years ago
Ronald S. Bultje	93f305473f	lavc: Convert some remaining strides to ptrdiff_t	11 years ago
Diego Biurrun	b2bed9325d	cosmetics: Group .name and .long_name together in codec/format declarations	11 years ago
Martin Storsjö	6fc8226e29	vp3: Check the framerate for validity Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Ronald S. Bultje	3bd062bf7f	vp3: Use hpeldsp instead of dsputil for half-pel functions This makes vp3 independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	015821229f	vp3: Use full transpose for all IDCTs This way, the special IDCT permutations are no longer needed. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Also remove the unused type == 0 cases from the plain C version of the idct. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Ronald S. Bultje	18df366a18	vp3: Embed idct_permutation array directly in VP3DecoderContext This makes the vp3 decoder less dependent on dsputil, and will aid in making it (eventually) dsputil-independent. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	759001c534	lavc decoders: work with refcounted frames.	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	4a73fbd9c5	vp3/5: move put_no_rnd_pixels_l2 from dsputil to VP3DSPContext. The function is only used in VP3 and VP5, so no need to have it in DSPContext.	12 years ago
Ronald S. Bultje	0e02b381b4	Remove put_no_rnd_pixels_l2 function pointer for w=16 from dsputil. The function is never used.	12 years ago
Ronald S. Bultje	aeaf268e52	vp3: integrate clear_blocks with idct of previous block. This is identical to what e.g. vp8 does, and prevents the function call overhead (plus dependency on dsputil for this particular function). Arm asm updated by Janne Grunau <janne-libav@jannau.net>.

Martin Storsjö	e33db35b4a	theora: Skip zero-sized headers This fixes a regression since `d9cf5f51` with theora over RTP (possibly with other variants of theora as well). In theora over RTP, the second of the 3 headers turns out to be 0 bytes long, which prior to `d9cf5f51` worked just fine. After `d9cf5f51`, reading from the bitstream reader fails (since the reader wasn't initialized but returned an error if initialized with 0 bits).

Ronald Bultje	ec86ba5731	vp3: Fix double free in vp3_decode_end() Signed-off-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	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(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	12 years ago
Luca Barbato	c1a02e884a	pixdesc: add av_pix_fmt_get_chroma_sub_sample Deprecate avcodec_get_chroma_sub_sample.	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Diego Biurrun	1218777ffd	avcodec: Convert some commented-out printf/av_log instances to av_dlog	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Mans Rullgard	28f9ab7029	vp3: move idct and loop filter pointers to new vp3dsp context This moves all VP3-specific function pointers from dsputil to a new vp3dsp context. There is no reason to ever use the VP3 IDCT where an MPEG2 IDCT is expected or vice versa. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Dale Curtis	27c2fb0f72	vp3: Assert on invalid filter_limit values. Signed-off-by: Dale Curtis <dalecurtis@chromium.org> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	e96b4a53df	vlc/rl: Add ff_ prefix to the nonstatic symbols Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Janne Grunau	9b4767e478	vp3: fix streams with non-zero last coefficient Fixes a regression introduced in `8b94df0f20`.	13 years ago
Reinhard Tartler	8b94df0f20	vp3dec: Check coefficient index in vp3_dequant() Based on a patch by Michael Niedermayer <michaelni@gmx.at> Fixes NGS00145, CVE-2011-4352 Found-by: Phillip Langlois Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Diego Biurrun	bc4d156140	vp3: Reorder some functions to fix VP3 build with Theora disabled.	13 years ago
Justin Ruggles	560f773c7d	avcodec: change number of plane pointers from 4 to 8 at next major bump. Add AV_NUM_DATA_POINTERS to simplify the bump transition. This will allow for supporting more planar audio channels without having to allocate separate pointer arrays.	13 years ago
Justin Ruggles	f3a29b750a	avcodec: move some AVCodecContext fields to an internal struct. A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.	13 years ago
Diego Biurrun	d1dfcb0829	vp3: remove some pointless comments	13 years ago
Ronald S. Bultje	8370e426e4	vp3: fix oob read for negative tokens and memleaks on error.	13 years ago
Anton Khirnov	357db4c263	lavc: use avpriv_ prefix for ff_split_xiph_headers. It's used in lavf.	13 years ago
Steven Walters	27237d524e	w32threads: support for frame multithreading Replace our incomplete w32threads implementation with x264's pthreads w32threads wrapper. Relicensed to LGPL with kind permission by Pegasys Inc. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago

Ronald S. Bultje	8cf9a09d40	vp3-mt: fix deadlock when first frame is not a keyframe.	14 years ago
David Conrad	a89f4ca005	Fix VP3 edge emulation With negative stride, the start of the edge_emu buffer should be pointing to the last line, not the end of the buffer. With positive stride, pointing to the end of the buffer was completely wrong.	14 years ago
Jason Garrett-Glaser	902685b8ab	VP3: fix decoding of videos with stride > 2048 Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't use an MPEG-like quantizer scale.	14 years ago
