|\ | | | | | | | | | | | | * commit '8e2346154e6d58b733fd20326ce706f82fd91b3e': libavutil: Hook up the rest of the gcc specific attributes to clang as well Merged-by: James Almer <jamrial@gmail.com>
| * libavutil: Hook up the rest of the gcc specific attributes to clang as wellMartin Storsjö2017-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hook up all attributes that don't have a MSVC specific version at the moment. See f637046d313 for details. These don't seem to be critical for building with clang in MSVC mode though, and thus haven't been hooked up until now. These seem to build fine with as old clang as 3.3 at least. (clang 3.3 disguises itself as gcc 4.2 normally, so all of these have been used for clang before, except for av_cold.) The clang version numbers themselves are useless for detecting what attributes are available, since Apple's clang builds use a completely different versioning (presenting itself as e.g. clang 8.0 instead of 3.8).

| * libavutil: Define the noreturn attribute for clang in MSVC mode as wellMartin Storsjö2017-03-21
| | | | | | | | | | | | | | | | | | | | | | This is a follow-up to f637046d313. Without the noreturn attribute set, avconv_opt.c fails to build after d2e6dd32a44 with the error "control may reach end of non-void function". By making sure the noreturn attribute is set properly, this compiles as intended. Signed-off-by: Martin Storsjö <martin@martin.st>
| * hwcontext: Make it easier to work with device typesMark Thompson2017-03-20
| | | | | | | | | | | | 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.
| * hwcontext: Add device derivationMark Thompson2017-03-20
| | | | | | | | | | Creates a new device context from another of a different type which refers to the same underlying hardware.

| | | | | | | | | | | | Also do some small cosmetic changes: Drop pointless _MMX suffix from ABSD2 macro name, drop pointless check for MMX support, we always assume MMX is available in our SIMD code, fix spelling.

| * hwcontext_vaapi: Try to support the VDPAU wrapperMark Thompson2017-02-13
| | | | | | | | | | | | | | | | 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>.
| * hwcontext_dxva2: support D3D9Exwm42017-02-11
| | | | | | | | | | | | | | | | D3D9Ex uses different driver paths. This helps with "headless" configurations when no user logs in. Plain D3D9 device creation will fail if no user is logged in, while it works with D3D9Ex. Signed-off-by: Anton Khirnov <anton@khirnov.net>
| * AVFrame: add an opaque_ref fieldwm42017-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an extended version of the AVFrame.opaque field, which can be used to attach arbitrary user information to an AVFrame. The usefulness of the opaque field is rather limited, because it can store only up to 32 bits of information (or 64 bit on 64 bit systems). It's not possible to set this field to a memory allocation, because there is no way to deallocate it correctly. The opaque_ref field circumvents this by letting the user set an AVBuffer, which makes the user data refcounted. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* | hwcontext_vaapi: Add support for mapping to DRM objectsMark Thompson2017-10-09
| | | | | | | | Uses vaExportSurfaceHandle() from libva2.
* | hwcontext: Perform usual initialisation on derived device contextsMark Thompson2017-10-09
| | | | | | | | | | | | | | The initialisation should be common. For libmfx, it was previously happening in the derivation function and this moves it out. For VAAPI, it fixes some failures when deriving from a DRM device because this initialisation did not run.
* | hwcontext_vaapi: Set message callbacks on internally-created devicesMark Thompson2017-10-09
| | | | | | | | | | The message callbacks are library-safe in libva2, so we can now use them.

| | | | | | | | | | This was duplicated between normal device creation and creation by derivation from a DRM device.
