* avcodec/x86/audiodsp_init: Remove obsolete MMX(EXT) functionsAndreas Rheinhardt2022-06-22
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from these functions are truely ancient 32bit x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* libavutil: Add wchartoutf8(), wchartoansi(), utf8toansi(), getenv_utf8(), ↵Nil Admirari2022-06-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | freeenv_utf8() and getenv_dup() wchartoutf8() converts strings returned by WinAPI into UTF-8, which is FFmpeg's preffered encoding. Some external dependencies, such as AviSynth, are still not Unicode-enabled. utf8toansi() converts UTF-8 strings into ANSI in two steps: UTF-8 -> wchar_t -> ANSI. wchartoansi() is responsible for the second step of the conversion. Conversion in just one step is not supported by WinAPI. Since these character converting functions allocate the buffer of necessary size, they also facilitate the removal of MAX_PATH limit in places where fixed-size ANSI/WCHAR strings were used as filename buffers. On Windows, getenv_utf8() wraps _wgetenv() converting its input from and its output to UTF-8. Strings returned by getenv_utf8() must be freed by freeenv_utf8(). On all other platforms getenv_utf8() is a wrapper around getenv(), and freeenv_utf8() is a no-op. The value returned by plain getenv() cannot be modified; av_strdup() is usually used when modifications are required. However, on Windows, av_strdup() after getenv_utf8() leads to unnecessary allocation. getenv_dup() is introduced to avoid such an allocation. Value returned by getenv_dup() must be freed by av_free(). Because of cleanup complexities, in places that only test the existence of an environment variable or compare its value with a string consisting entirely of ASCII characters, the use of plain getenv() is still preferred. (libavutil/log.c check_color_terminal() is an example of such a place.) Plain getenv() is also preffered in UNIX-only code, such as bktr.c, fbdev_common.c, oss.c in libavdevice or af_ladspa.c in libavfilter. Signed-off-by: Martin Storsjö <martin@martin.st>

* avformat/matroskaenc: Don't check twice whether to write tagsAndreas Rheinhardt2022-06-20
| | | | | | | | | | | | | | | Because not all metadata is written as tags, the Matroska muxer filters out the tags that are not written as tags. Therefore the code first checks whether a Tag master element needs to be opened for a given stream/chapter/attachment/global metadata. If the answer turns out to be yes, it is checked again whether a given AVDictionaryEntry is written as a tag. This commit changes this: The Tag element is opened unconditionally and in case it turns out that it was unneeded, it is discarded again. This is possible because the Tag element is written into its own dynamic buffer. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat/matroskaenc: Don't waste bytes to Write Tag length fieldsAndreas Rheinhardt2022-06-20

* tests/checkasm/sw_scale: Fix alignment for movdqaMichael Goulet2022-06-20
| | | | | | | SSE3 instruction movdqa in ff_yuv2yuvX_sse3() expects a 16-byte aligned address for a memory address, or else a segfault is generated. The src_pixels buffer below was not aligned to 16 bytes on the stack necessarily, so we got segfaults during fate-checkasm-sw_scale. Therefore 16-byte align all of these local variables, aligning them too much shouldn't hurt.
* lavc/libx264.c: Fix possible UB by NULL pointer LHSMichael Goulet2022-06-20

* lavfi/drawutils: improve colorspace supportrcombs2022-06-19
| | | | | | | | | | | | | | | | | | | | | - Introduce ff_draw_init2, which takes explicit colorspace and range args - Use lavu/csp and lavfi/colorspace for conversion, rather than the lavu/colorspace.h macros - Use the passed-in colorspace when performing RGB->YUV conversions The upshot of this is: - Support for YUV spaces other than BT601 - Better rounding for all conversions - Particular rounding improvements in >8-bit formats, which previously used simple left-shifts - Support for limited-range RGB - Support for full-range YUV in non-J pixfmts Due to the rounding improvements, this results in a large number of minor changes to FATE tests.

* 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>
