Both are autodetected, and their dependency on cuda is checked
elsewhere.
Fixes ticket #6849.

This was added in early 2013 and abandoned several months later; as far as
I can tell, there are no external users. Future OpenCL use will be via
hwcontext, which requires neither special OpenCL-only API nor global state
in libavutil.
All internal users are also deleted - this is just the unsharp filter
(replaced by unsharp_opencl, which is more flexible) and the deshake filter
(no replacement).
|
|
Intended to replace existing opencl mode of the unsharp filter.
Supports many more pixel formats and works without immediate upload
and download of frame data. The options are compatible with the
existing filter.
|
|
Input and output formats must be the same, the overlay format must be
the same as the input except possibly with an additional alpha component.

|
Using cl_arm_import_memory. Unfortunately, despite this not being a
standard extension, the function clImportMemoryARM() is not accessible
via clGetExtensionFunctionAddressForPlatform(). This means that it has
to be linked directly to the ARM OpenCL binary, so making a portable
binary is not possible as it is with all other mapping extensions.
|
|
Using cl_khr_d3d11_sharing and cl_intel_d3d11_nv12_media_sharing.
|
|
Using cl_khr_dx9_media_sharing.
|
|
Uses the cl_intel_va_api_media_sharing extension, which supports only
NV12 surfaces and only mapping from QSV to OpenCL.
|
|
Supports all surface formats in common between the two.

this will simplify libvpxenc/dec.c and ensure more stable versions of
the codecs are present.

This was predictably nightmarish, given how ridiculous mpeg4 is.
I had to stare at the cuvid parser output for a long time to work
out what each field was supposed to be, and even then, I still don't
fully understand some of them. Particularly:
vop_coded: If I'm reading the decoder correctly, this flag will always
be 1 as the decoder will not pass the hwaccel any frame
where it is not 1.
divx_flags: There's obviously no documentation on what the possible
flags are. I simply observed that this is '0' for a
normal bitstream and '5' for packed b-frames.
gmc_enabled: I had a number of guesses as to what this mapped to.
I picked the condition I did based on when the cuvid
parser was setting flag.
Also note that as with the vdpau hwaccel, the decoder needs to
consume the entire frame and not the slice.
|
|
Once I remembered that there's a separate decoder type for mpeg1,
even though params struct is shared with mpeg2, everything worked.

libavcodec: Don't use dllexport, only dllimport when building DLLs

select should not be used with external libraries. It's mean to soft
enable internal modules/features.

The only purpose of dllexport (which is set while building the library
that exports the symbols) is to have the linker automatically
export such symbols into a DLL without using a def file - it doesn't
affect the generated code.
For both MSVC and mingw builds, this isn't essential since we override
what symbols to export via an autogenerated def file instead.
Update a comment in configure to refer to the right concept.
With lld, this avoids warnings about duplicate export directives,
when some symbols are requested to be exported both via dllexport
attributes and via the autogenerated def file.
This also reduces the number of lines of code marginally.

This is mostly straight-forward. The weird part is that it should
just work for mpeg1, but I see corruption in my test cases, so I'm
going to try and fix that separately.
|
|
By putting the call in a subshell, the problem of it spilling
cleanup-decision from a previous library to other libraries is avoided.
For example, it could have already cleaned up cuda_extralibs in a
previous library that depended on cuda. Then when it gets to avutil, it
will never pick up the dependency of avutil to cuda, which depends on
libdl, which in turn results in a missing -ldl extralib, resulting in
link failures in certain configurations.

This avoids having to use either "dumpbin -headers" to find out
the current architecture, or pass $ARCH from configure to deduce it.
When configuring with --disable-asm, ARCH is equal to "c", which doesn't
give any indication of what symbol prefix is to be used.

- Move a variable closer to where it is used
- Add an explanatory comment
- Simplify a crosscompile check
- Minor SHFLAGS simplification
- Coalesce some threads tests

This hwaccel is interesting because it also works for wmv3/9 content,
which is not supported by the nvidia parser used by cuviddec.
