* avpacket: fix size check in packet_allocAndreas Cadhalpun2016-01-07
| | | | | | | | | | | The previous check only caught sizes from -AV_INPUT_BUFFER_PADDING_SIZE to -1. This fixes ubsan runtime error: signed integer overflow: 2147483647 + 32 cannot be represented in type 'int' Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

* h264: improve behaviour with invalid reference listsAnton Khirnov2016-01-01
| | | | | | | | | | | | | Before 741b494fa8cd28a7d096349bac183893c236e3f9, when the reference list modification description was invalid, the code would substitute the corresponding reference from the initial ("default") reference list. After that commit, it will just return an error. Since there are apparently invalid samples in the wild that used to play fine with the old code, it is a good idea to re-add some sort of error resilience here. So, when the reference list modification results in a missing frame, substitute a previous reference frame for it. The relevant sample again decodes fine with the same output as previously.

* x86: use emms after ff_int32_to_float_fmul_scalar_sseJanne Grunau2015-12-30
| | | | | | | | | | | | | | | | | | | | | Intel's Instruction Set Reference (as of September 2015) clearly states that cvtpi2ps switches to MMX state. Actual CPUs do not switch if the source is a memory location. The Instruction Set Reference from 1999 (Order Number 243191) describes this behaviour but all later versions I've seen have make no distinction whether MMX registers or memory is used as source. The documentation for the matching SSE2 instruction to convert to double (cvtpi2pd) was fixed (see the valgrind bug https://bugs.kde.org/show_bug.cgi?id=210264). It will take time to get a clarification and fixes in place. In the meantime it makes sense to change ff_int32_to_float_fmul_scalar_sse to be correct according to the documentation. The vast majority of users will have SSE2 so a change to the SSE version has little effect. Fixes fate-checkasm on x86 valgrind targets. Valgrind 'bug' reported as https://bugs.kde.org/show_bug.cgi?id=357059

* dca: remove unused decode_hf function and quant_d tablesAlexandra Hájková2015-12-24
| | | | | They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.
* dca: change the core to work with integer coefficients.Alexandra Hájková2015-12-23
| | | | | | | | | | | | The DCA core decoder converts integer coefficients read from the bitstream to floats just after reading them (along with dequantization). All the other steps of the audio reconstruction are done with floats which makes the output for the DTS lossless extension (XLL) actually lossy. This patch changes the DCA core to work with integer coefficients until QMF. At this point the integer coefficients are converted to floats. The coefficients for the LFE channel (lfe_data) are not touched. This is the first step for the really lossless XLL decoding.
* dca: Add math helpers.Alexandra Hájková2015-12-23
| | | | They will be used by the integer core decoder.

* exr: fix out of bounds read in get_codeAndreas Cadhalpun2015-12-16
| | | | | | | | This macro unconditionally used out[-1], which causes an out of bounds read, if out is the very beginning of the buffer. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* opus: Fix typo causing overflow in silk_stabilize_lsfAndreas Cadhalpun2015-12-16
| | | | | | | | | | Due to this typo max_center can be too large, causing nlsf to be set to too large values, which in turn can cause nlsf[i - 1] + min_delta[i] to overflow to a negative value, which is not allowed for nlsf and can cause an out of bounds read in silk_lsf2lpc.

* arm: add ff_int32_to_float_fmul_array8_neonJanne Grunau2015-12-14
| | | | | | | | | | | | | | | | | | | | | | | Quite a bit faster than int32_to_float_fmul_array8_c calling ff_int32_to_float_fmul_scalar_neon through FmtConvertContext. Number of cycles per int32_to_float_fmul_array8 call while decoding padded.dts on exynos5422: before after change cortex-a7: 1270 951 -25% cortex-a15: 434 285 -34% checkasm --bench cycle counts: cortex-a15 cortex-a7 int32_to_float_fmul_array8_c: 1730.4 4384.5 int32_to_float_fmul_array8_neon_c: 571.5 1694.3 int32_to_float_fmul_array8_neon: 374.0 1448.8 Interesting are the differences between int32_to_float_fmul_array8_neon_c and int32_to_float_fmul_array8_neon. The former is current behaviour of calling ff_int32_to_float_fmul_scalar_neon repeatedly from the c function, The raw numbers differ since checkasm uses different lengths than the dca decoder.

* arm64: port synth_filter_float_neon from armJanne Grunau2015-12-14
| | | | | | | | | | | | | | ~25% faster dts decoding overall. The checkasm CPU cycles numbers are not that useful since synth_filter_float() calls FFTContext.imdct_half(). cortex-a57 cortex-a53 synth_filter_float_c: 1866.2 3490.9 synth_filter_float_neon: 915.0 1531.5 With fftc.imdct_half forced to imdct_half_neon: cortex-a57 cortex-a53 synth_filter_float_c: 1718.4 3025.3 synth_filter_float_neon: 926.2 1530.1

* arm: add a cpu flag for the VFPv2 vector modeJanne Grunau2015-12-14
| | | | | | | | | | | | | | The vector mode was deprecated in ARMv7-A/VFPv3 and various cpu implementations do not support it in hardware. Vector mode code will depending the OS either be emulated in software or result in an illegal instruction on cpus which does not support it. This was not really problem in practice since NEON implementations of the same functions are preferred. It will however become a problem for checkasm which tests every cpu flag separately. Since this is a cpu feature newer cpu do not support anymore the behaviour of this flag differs from the other flags. It can be only activated by runtime cpu feature selection.

* lavc: Drop exporting 2-pass encoding statsVittorio Giovara2015-12-07
| | | | | | | | | | | | | | These variables are coming from mpegvideoenc where are supposedly used as bit counters on various frame properties. However their use is unclear as they lack documentation, are available only from a very small subset of encoders, and they are hardly used in the wild. Also frame_bits in aacenc is employed in a similar way. Remove this functionality from AVCodecContex, these variable are mostly frame properties, and too few encoders support setting them with anything useful.

* lavc: Deprecate coder_type and its symbolsVittorio Giovara2015-12-07
| | | | | | | | | | Most option values are simply unused or ignored and in practice the majory of codecs only need to check whether to enable rle or not. Add appropriate codec private options which better expose the allowed features. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
* h264: do not call frame_start() for missing framesAnton Khirnov2015-12-07
