* x86/aacpsdsp: add ff_ps_hybrid_synthesis_deint_{sse,sse4}James Almer2017-06-18
| | | | About 2x faster than the c version.
* avutil/tests: remove float_dsp testJames Almer2017-06-14
| | | | | | It's been ported to checkasm. Signed-off-by: James Almer <jamrial@gmail.com>
* hwcontext: Improve allocation in derived contextsMark Thompson2017-06-14
| | | | | | | | | Use the flags argument of av_hwframe_ctx_create_derived() to pass the mapping flags which will be used on allocation. Also, set the format and hardware context on the allocated frame automatically - the user should not be required to do this themselves. (cherry picked from commit c5714b51aad41fef56dddac1d542e7fc6b984627)
* hwcontext_qsv: Implement mapping frames to the child device typeMark Thompson2017-06-14
| | | | (cherry picked from commit e1c5d56b18b82e3fb42382b1b1f972e8b371fc38)
* hwcontext_qsv: Implement mapping frames from the child device typeMark Thompson2017-06-14
| | | | | | Factorises out existing surface initialisation code to reuse. (cherry picked from commit eaa5e0710496db50fc164806e5f49eaaccc83bb5)
* hwcontext: Add frame context mapping for nontrivial contextsMark Thompson2017-06-14
| | | | | | | | | Some frames contexts are not usable without additional format-specific state in hwctx. This change adds new functions frames_derive_from and frames_derive_to to initialise this state appropriately when deriving a frames context which will require it to be set. (cherry picked from commit 27978155bc661eec9f22bcf82c9cfc099cff4365)
* hwcontext_qsv: Support derivation from child devicesMark Thompson2017-06-14
| | | | (cherry picked from commit aa51bb3d2756ed912ee40645efccf5f4a9609696)
* hwcontext: Make it easier to work with device typesMark Thompson2017-06-14
| | | | | | | | Adds functions to convert to/from strings and a function to iterate over all supported device types. Also adds a new invalid type AV_HWDEVICE_TYPE_NONE, which acts as a sentinel value. (cherry picked from commit b7487f4f3c39b4b202e1ea7bb2de13902f2dee45)
* hwcontext: Add device derivationMark Thompson2017-06-14
| | | | | | | Creates a new device context from another of a different type which refers to the same underlying hardware. (cherry picked from commit b266ad56fe0e4ce5bb70118ba2e2b1dabfaf76ce)
* hwcontext_vaapi: Try to support the VDPAU wrapperMark Thompson2017-06-14
| | | | | | | | | | The driver is somewhat bitrotten (not updated for years) but is still usable for decoding with this change. To support it, this adds a new driver quirk to indicate no support at all for surface attributes. Based on a patch by wm4 <nfxjfg@googlemail.com>. (cherry picked from commit e791b915c774408fbc0ec9e7270b021899e08ccc)
* x86inc: Add some additional cpuflag relationsHenrik Gramner2017-06-12
| | | | | | | | Simplifies writing assembly code that depends on available instructions. LZCNT implies SSE2 BMI1 implies AVX+LZCNT AVX2 implies BMI2
* x86inc: Remove argument from WIN64_RESTORE_XMMAnton Mitrofanov2017-06-09
| | | | | The use of rsp was pretty much hardcoded there and probably didn't work otherwise with stack_size > 0.
* x86inc: Prefer r14/r15 over r12/r13 on x86-64Henrik Gramner2017-06-09
| | | | | | | Due to a peculiarity in the ModR/M addressing encoding, the r12 and r13 registers sometimes requires an additional byte when used as a base register. r14 and r15 doesn't have that issue, so prefer using them.
* x86inc: Make REP_RET identical to RET in SSSE3+ functionsHenrik Gramner2017-06-09
| | | | There's no point in emitting a rep prefix before ret on modern CPUs.
* x86inc: Fix call with memory operandsHenrik Gramner2017-06-09
| | | | | | We overload the `call` instruction with a macro, but it would misbehave when the macro argument wasn't a valid identifier. Fix it by explicitly checking if the argument is an identifier.

* | avutil/hwcontext_dxva2: Don't improperly free IDirect3DSurface9 objectsAaron Levinson2017-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add dxva2_pool_release_dummy() and use it in call to av_buffer_create() in dxva2_pool_alloc(). Prior to this change, av_buffer_create() was called with NULL for the third argument, which indicates that av_buffer_default_free() should be used to free the buffer's data. Eventually, it gets to buffer_pool_free() and calls buf->free() on a surface object (which is av_buffer_default_free()). This can result in a crash when the debug version of the C-runtime is used on Windows. While it doesn't appear to result in a crash when the release version of the C-runtime is used on Windows, it likely results in memory corruption, since av_free() is being called on memory that was allocated using IDirectXVideoAccelerationService::CreateSurface().

* | hwcontext_videotoolbox: fix fate-sourcewm42017-05-15
| | | | | | | | Thanks to James Darnley for figuring out what the hell it wanted.
* | videotoolbox: add hwcontext supportwm42017-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds tons of code for no other benefit than making VideoToolbox support conform with the new hwaccel API (using hw_device_ctx and hw_frames_ctx). Since VideoToolbox decoding does not actually require the user to allocate frames, the new code does mostly nothing. One benefit is that ffmpeg_videotoolbox.c can be dropped once generic hwaccel support for ffmpeg.c is merged from Libav. Does not consider VDA or VideoToolbox encoding. Fun fact: the frame transfer functions are copied from vaapi, as the mapping makes copying generic boilerplate. Mapping itself is not exported by the VT code, because I don't know how to test.

| | | | | | | | | | | | | | | | | | | | | | When allocating stack space with an alignment requirement that is larger than the current stack alignment we need to store a copy of the original stack pointer in order to be able to restore it later. If we chose to use another register for this purpose we should not pick eax/rax since it can be overwritten as a return value. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* | libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1Aaron Levinson2017-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Purpose: libavutil/thread.h: Fixed g++ build error when ASSERT_LEVEL is greater than 1. This is only relevant when thread.h is included by C++ files. In this case, the relevant code is only defined if HAVE_PTHREADS is defined as 1. Use configure --assert-level=2 to do so. Note: Issue discovered as a result of Coverity build failure. Cause of build failure pinpointed by Hendrik Leppkes. Comments: -- libavutil/thread.h: Altered ASSERT_PTHREAD_NORET definition such that it uses av_make_error_string instead of av_err2str(). av_err2str() uses a "parenthesized type followed by an initializer list", which is apparently not valid C++. This issue started occurring because thread.h is now included by the DeckLink C++ files. The alteration does the equivalent of what av_err2str() does, but instead declares the character buffer as a local variable. Signed-off-by: Marton Balint <cus@passwd.hu>

| * avutil: fix data race in av_get_cpu_flags()Wan-Teh Chang2016-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the one-time initialization in av_get_cpu_flags() thread-safe. The static variables |flags|, |cpuflags_mask|, and |checked| in libavutil/cpu.c are read and written using normal load and store operations. These are considered as data races. The fix is to use atomic load and store operations. Remove the |checked| variable because the invalid value of -1 for |flags| can be used to indicate the same condition. Rename |flags| to |cpu_flags| and move it to file scope. The fix can be verified by running the libavutil/tests/cpu_init.c test program under ThreadSanitizer: ./configure --toolchain=clang-tsan make libavutil/tests/cpu_init libavutil/tests/cpu_init There should be no warnings from ThreadSanitizer.
