* Give IDCT matrix transpose macro a more descriptive nameDiego Biurrun2014-02-27
| | | | This also avoids a macro name clash and related warning on ARM.
* lavc: Edge emulation with dst/src linesizeRonald S. Bultje2013-11-15
| | | | | | 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.
* vp3: stop using deprecated avcodec_set_dimensionsAnton Khirnov2013-10-31

* lavc: Convert some remaining strides to ptrdiff_tRonald S. Bultje2013-10-15

* cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun2013-10-03

* vp3: Check the framerate for validityMartin Storsjö2013-09-16
| | | | | | Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* vp3: Use hpeldsp instead of dsputil for half-pel functionsRonald S. Bultje2013-04-19
| | | | | | This makes vp3 independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>
* vp3: Use full transpose for all IDCTsRonald S. Bultje2013-04-15
| | | | | | | | | | | 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>
* vp3: Embed idct_permutation array directly in VP3DecoderContextRonald S. Bultje2013-04-08
| | | | | | | 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>
* lavc decoders: work with refcounted frames.Anton Khirnov2013-03-08
|
* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* vp3/5: move put_no_rnd_pixels_l2 from dsputil to VP3DSPContext.Ronald S. Bultje2013-01-21
| | | | | The function is only used in VP3 and VP5, so no need to have it in DSPContext.
* Remove put_no_rnd_pixels_l2 function pointer for w=16 from dsputil.Ronald S. Bultje2013-01-19
| | | | The function is never used.
* vp3: integrate clear_blocks with idct of previous block.Ronald S. Bultje2013-01-19
| | | | | | | | | 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>. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* theora: Skip zero-sized headersMartin Storsjö2013-01-17
| | | | | | | | | | | | | 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).

* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | 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>
* lavc: fix decode_frame() third parameter semantics for video decodersAnton Khirnov2012-12-04
| | | | It's got_frame, not data size
* pixdesc: add av_pix_fmt_get_chroma_sub_sampleLuca Barbato2012-11-13
| | | | Deprecate avcodec_get_chroma_sub_sample.
* Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormatAnton Khirnov2012-10-08

* avcodec: Convert some commented-out printf/av_log instances to av_dlogDiego Biurrun2012-10-01

* Replace all CODEC_ID_* with AV_CODEC_ID_*Anton Khirnov2012-08-07

* vp3: move idct and loop filter pointers to new vp3dsp contextMans Rullgard2012-07-18
| | | | | | | | 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>

* vp3: Reorder some functions to fix VP3 build with Theora disabled.Diego Biurrun2011-12-20

* avcodec: change number of plane pointers from 4 to 8 at next major bump.Justin Ruggles2011-12-02
| | | | | | 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.
* avcodec: move some AVCodecContext fields to an internal struct.Justin Ruggles2011-11-19
| | | | | | | | 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.

* Fix VP3 edge emulationDavid Conrad2011-02-19
| | | | | | 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.
* VP3: fix decoding of videos with stride > 2048Jason Garrett-Glaser2011-02-18
| | | | | Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't use an MPEG-like quantizer scale.
* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
