* hevc: Conceal zero tdLuca Barbato2014-02-09
| | | | | | | | | It was done only in check_mvset(), while mv_scale() is called also by dist_scale(). Sample-Id: 00001579-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* mlp_parser: fix request_channel_layout behavior.Tim Walker2014-02-08
| | | | | | | | | | | When request_channel_layout is 0, all substreams should be decoded. Thanks to Michael Niedermayer for spotting. Also fix a mismatch between the parser and decoder when request_channel_layout is a subset of Stereo.

* Mirillis FIC video decoderKostya Shishkov2014-02-08
| | | | | | Does not contain cursor rendering yet. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
* mlp: improve request_channel_layout behavior.Tim Walker2014-02-08
| | | | | | | | | | Don't decode further substreams if request_channel_layout is a subset of the current substream's channel_layout. Before, we would only discard further substreams if request_channel_layout matched the substream's channel_layout extactly, thus decoding additional channels which the caller would probably end up downmixing.

* x86: use the inline int8x8_fmul_int32 only if inline SSE2 is availbaleJanne Grunau2014-02-08
| | | | | Fixes compilation with MSVC. Also does not rely on on earlier config.h include but include it directly.
* dcadsp: split lfe_dir casesChristophe Gisquet2014-02-07
| | | | | | | | | The x86 runs short on registers because numerous elements are not static. In addition, splitting them allows more optimized code, at least for x86. Arm asm changes by Janne Grunau. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* x86: dcadsp: implement int8x8_fmul_int32Christophe Gisquet2014-02-07
| | | | | | | | | | | For the callable function (as opposed to the inline one): C SSE SSE2 SSE4 Win32: 47 42 29 26 Win64: 30 33 25 23 The SSE version is neither compiled nor set for ARCH_X86_64, as the inlinable function takes over. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* dcadsp: add int8x8_fmul_int32 to dsp contextChristophe Gisquet2014-02-07
| | | | | | | | | | | | | | It is currently declared as a macro who is set to inlinable functions, among which a Neon and a default C implementations. Add a DSP parameter to each inline function, unused except by the default C implementation which calls a function from the DSP context. On an Arrandale CPU, gain for an inlined SSE2 function vs. a call: - Win32: 29 to 26 cycles - Win64: 25 to 23 cycles Signed-off-by: Janne Grunau <janne-libav@jannau.net>

* vp8: use a fixed-size edge emu bufferAnton Khirnov2014-02-04

* utvideoenc: Add support for the new BT.709 FourCCs for YCbCrJan Ekström2014-02-04
| | | | | | | | With cli usage the decoder might have not set the colorspace during encoder init, manual colorspace override might be needed in such cases. Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | | | The idct implementation cannot be changed after the quantization matrices are read since it use a different permutaion. Bug-Id: videolan/7411
* atrac3plus: Make initialization dependant on channel count rather than ↵Jan Ekström2014-01-31
| | | | | | | | channel map Makes it easier to recreate an AVCodecContext for ATRAC3+ decoding, which is needed in multimedia frameworks, as well as in general cases where demuxing and decoding are separate entities.

| | | | | | | | Should fix crashes or corrupt output on pre-SSE2 CPUs when they were using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in hfix or hvar single-edge (left/right) extension functions. Signed-off-by: Janne Grunau <janne-libav@jannau.net>

| | | | | | | | | Add checks to the fast functions used with CODEC_FLAGS2_FAST and move the check for all other functions to before the invalid memory is accessed. Fixes https://trac.videolan.org/vlc/ticket/9713 with CODEC_FLAGS2_FAST. CC: libav-stable@libav.org
* avutil: remove timer.h include from internal.hJanne Grunau2014-01-25

* vp9: fix bugs in updating coef probabilities with parallelmode=1Guillaume Martres2014-01-24
| | | | | | | | | - The memcpy was completely wrong because s->prob_ctx[s->framectxid].coef is a [4][2][2][6][6][3] array, whereas s->prob.coef is a [4][2][2][6][6][11] array. - The additional check was committed to ffmpeg by Ronald S. Bultje. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* h264: skip chroma edges at the picture boundary while deblocking 4:4:4Janne Grunau2014-01-22
| | | | | | | | | This handles macroblock edges for the chroma components in the same way as for the luma compoment for 4:4:4 streams. The Spec explicitly states that the deblocking filter is not applied to edges at the boundary of the picture. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
* lavc: do not force the emu edge flagAnton Khirnov2014-01-21
| | | | | | | The default get_buffer2() implementation (and possibly some user ones) does not allocate edges when this flag is set, which may expose bugs in some decoders. Until the 10 release is out, it is safer to remove this part.
