* nvenc: better error handlingAnton Khirnov2016-01-12
| | | | Return proper error codes and print more descriptive error messages.
* movenc-test: stop setting the GLOBAL_HEADER codec flagAnton Khirnov2016-01-12
| | | | | This test does no encoding, setting the flag was done just to silence the warning removed in the previous commit.
* mux: drop the warning about global headersAnton Khirnov2016-01-12
| | | | | The AVStream codec context is often not (and should not be) the actual encoding context, so this warning will be spurious in many cases.

* arm: Fix vfp dead code elimination with have_vfp_vmMartin Storsjö2016-01-08
| | | | | | | | | This fixes builds with --disable-vfp. Checking for the armv6 cpu flag is incorrect, since vfpv2 isn't armv6 specific. Signed-off-by: Martin Storsjö <martin@martin.st>
* checkasm: Check register clobbering on aarch64Martin Storsjö2016-01-07
| | | | | | | This is disabled on iOS, since iOS uses a slightly different ABI for vararg parameters. Signed-off-by: Martin Storsjö <martin@martin.st>
* checkasm: Check register clobbering on armMartin Storsjö2016-01-07
| | | | | | | | | | | Use two separate functions, depending on whether VFP/NEON is available. This is set to require armv5te - it uses blx, which is only available since armv5t, but we don't have a separate configure item for that. (It also uses ldrd, which requires armv5te, but this could be avoided if necessary.) Signed-off-by: Martin Storsjö <martin@martin.st>

* 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
* checkasm: x86: post commit review fixesJanne Grunau2015-12-29
| | | | | | | Check the full FPU tag word instead of only the lower half and simplify the comparison. Use upper-case function base name as macro name to instantiate both checked_call variants.

* 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.

* x86: checkasm: check for or handle missing cleanup after MMX instructionsJanne Grunau2015-12-21
| | | | | | | | Not every asm routine is expected clear the MMX state after returning. It is however a requisite for testing floating point code in checkasm. Annotate functions requiring cleanup with declare_func_emms() and issue emms after the call. The remaining functions are checked for having a cleared MMX state after return.

* 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.

| | | | | | | | | | | | | | ~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.
