* avutil/cpu_internal: Fix check for SSE2SLOWAndreas Rheinhardt2022-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For SSE2 and SSE3, there are four states that the two flags involved (AV_CPU_FLAG_SSE[23] and AV_CPU_FLAG_SSE[23]SLOW) can convey. When ordered from worst to best they are: 1. both flags unset (SSE[23] unavailable) 2. the slow flag set, the ordinary flag unset (this is designed for cases where SSE2 is available, but so slow that MMX(EXT)/SSE code is usually faster) 3. both flags set (SSE2 is available, but there might be scenarios where MMX(EXT)/SSE code is faster) 4. the ordinary flag set, the slow flag unset (this is the normal case) The ordinary macros for checking cpuflags return true in the latter two cases; the fast macros only return true for the latter case. Yet the macros to check for slow currently only return true in case three. This seems unintended. In fact, the only uses of the slow macros are all of the form if (EXTERNAL_SSE2(cpu_flags) || EXTERNAL_SSE2_SLOW(cpu_flags)) where the check for EXTERNAL_SSE2_SLOW is completely redundant. Even more importantly, it is not what was intended. Before 6369ba3c9cc74becfaad2a8882dff3dd3e7ae3c0, the checks passed in cases 2 to 4. Said commit changed this to something that only passes for the third case. Commits 7fb758cd8ed08e4a37f10e25003953d13c68b8cd and c1913064e38cb338039f29c280a0dacc3fd1e451 restored the old behaviour, yet merging 4efab89332ea39a77145e8b15562b981d9dbde68 (in commit ac774cfa571734c49c26e2d3387adccff8957ff8) broke this again by changing it to what it is now.* This commit changes the macros to make the slow macros check whether a specific instruction is supported, even if slow. This restores the intended meaning to all uses of the SLOW macros and is generally more natural. *: Libav only checks for EXTERNAL_SSE2_SLOW, i.e. for the third case only.

* avcodec/vlc: Use structure instead of VLC_TYPE array as VLC elementAndreas Rheinhardt2022-06-17
| | | | | | | | | | | | | | | | | | In C, qualifiers for arrays are broken: const VLC_TYPE (*foo)[2] is a pointer to an array of two const VLC_TYPE elements and unfortunately this is not compatible with a pointer to a const array of two VLC_TYPE, because the latter does not exist as array types are never qualified (the qualifier applies to the base type instead). This is the reason why get_vlc2() doesn't accept a const VLC table despite not modifying the table at all, as there is no automatic conversion from VLC_TYPE (*)[2] to const VLC_TYPE (*)[2]. Fix this by using a structure VLCElem for the VLC table. This also has the advantage of making it clear which element is which. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avdevice/pulse_audio_dec: reduce default fragment sizeMarton Balint2022-06-16
| | | | | | | | | | | | | Reduces default fragment size from the pulse audio default of 2 sec to 50 ms. This also has an effect on the size of the returned frames, which will be around 50 ms as well, making timestamps more accurate. This should fix the regression in ticket #9776. Pulseaudio timestamps for monitor sources are still pretty inaccurate for me, but I don't see how else should we query latencies from the library. Signed-off-by: Marton Balint <cus@passwd.hu>

* avformat/matroskaenc: Convert chapter metadataAndreas Rheinhardt2022-06-16
| | | | | | | | | | | | It is no longer converted since mkv_write_chapters() is called before mkv_write_tags() which happens since commit 4ebfc13c338423cf48f1a1266c890422367f7775.

* avformat/matroskaenc: Reset cur_master_element when discarding masterAndreas Rheinhardt2022-06-16
| | | | | | | | | | | | | | Before this patch the muxer writes an invalid file (namely one in which the Projection master is a child of the Colour element) if the following conditions are met: a) The stream contains AVMasteringDisplayMetadata without primaries and luminance (i.e. useless AVMasteringDisplayMetadata). b) The stream contains AV_PKT_DATA_SPHERICAL side data. c) All the colour elements of the stream are equal to default (i.e. unknown). Fortunately these conditions are very unlikely to be met. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* all: Replace if (ARCH_FOO) checks by #if ARCH_FOOAndreas Rheinhardt2022-06-15
| | | | | | | | | | | | | | | | | | This is more spec-compliant because it does not rely on dead-code elimination by the compiler. Especially MSVC has problems with this, as can be seen in https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/296373.html or https://ffmpeg.org/pipermail/ffmpeg-devel/2022-May/297022.html This commit does not eliminate every instance where we rely on dead code elimination: It only tackles branching to the initialization of arch-specific dsp code, not e.g. all uses of CONFIG_ and HAVE_ checks. But maybe it is already enough to compile FFmpeg with MSVC with whole-programm-optimizations enabled (if one does not disable too many components).

* swresample/resample: Properly empty MMX stateAndreas Rheinhardt2022-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | There is a x86-32 MMXEXT implementation for resampling planar 16bit data. multiple_resample() therefore calls emms_c() if it thinks that this needed. And this is bad: 1. It is a maintenance nightmare because changes to the x86 resample DSP code would necessitate changes to the check whether to call emms_c(). 2. The return value of av_get_cpu_flags() does not tell whether the MMX DSP functions are in use, as they could have been overridden by av_force_cpu_flags(). 3. The MMX DSP functions will never be overridden in case of an x86-32 build with --disable-sse2. In this scenario lots of resampling tests (like swr-resample_exact_lin_async-s16p-8000-48000) fail because the cpuflags indicate that SSE2 is available (presuming that the test is run on a CPU with SSE2). 4. The check includes a call to av_get_cpu_flags(). This is not optimized away for arches other than x86-32. 5. The check takes about as much time as emms_c() itself, making it pointless. This commit therefore removes the check and calls emms_c() unconditionally (it is a no-op for non-x86). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
