* avutil/opt: Don't use NULL for %s string in a log messageAndreas Rheinhardt2020-04-01
| | | | | | | | | | | | | | | If one calls av_opt_set() with an incorrect string to set the value of an option of type AV_OPT_TYPE_VIDEO_RATE, the given string is used in a log message via %s. This also happens when the string is actually a nullpointer in which case using it for %s is forbidden. This commit changes this by erroring out early in case of a nullpointer. This also fixes a warning from GCC 9.2: "‘%s’ directive argument is null [-Wformat-overflow=]" Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| | | | | | By itself, this allows 6-point, 10-point and 30-point transforms. When the 9-point transform is added it allows for 18-point FFT, and also for a 36-point MDCT (used by MP3).

* hwcontext_vulkan: fix imported image bitmaskLynne2020-03-17

* hwcontext_vulkan: support more than one plane per DMABUF layerLynne2020-03-12
| | | | | Requires the dmabuf modifiers extension. Allows for importing of compressed images with a second plane.
* hwcontext_vulkan: duplicate DMABUF objects before importing themLynne2020-03-12
| | | | | | | | The specifications are very vague about who has ownership, and in this case, Vulkan takes ownership of all DMABUF FDs passed to it, causing errors to occur if someone gave us images for mapping which were meant to be kept. The old behavior worked with one-way VAAPI and DMABUF imports, but was broken with clients like wlroots' dmabuf-capture.
* hwcontext_vulkan: initialize semaphores of DMABUF importsLynne2020-03-12
| | | | | | | | | There was a recent change in Intel's driver that triggered a driver-internal error if the semaphore given to the command buffer wasn't initialized. Given that the specifications require the semaphore to be initialized, this is within spec. Unlike what's causing it in the first place, which is that there are no ways to extract/import dma sync objects from DMABUFs, so we must leave our semaphores bare.

* hwcontext_vulkan: minor corrections for DMABUF mappingLynne2020-03-12
| | | | We need to consider the amount of layers instead of the image's planes.
* hwcontext_vaapi: Only accept a render node when deriving from DRM deviceMark Thompson2020-02-24
| | | | | | | | | | | | | If we are given a non-render node, try to find the matching render node and fail if that isn't possible. libva will not accept a non-render device which is not DRM master, because it requires legacy DRM authentication to succeed in that case: <https://github.com/intel/libva/blob/master/va/drm/va_drm.c#L68-L75>. This is annoying for kmsgrab because in most recording situations DRM master is already held by something else (such as a windowing system), leading to device derivation not working and forcing the user to create the target VAAPI device separately.
* lavu/hwcontext_vaapi: add vaapi_format_map support for Y210Linjie Fu2020-02-24
| | | | | | | | | | | | | VA_RT_FORMAT describes the desired sampling format for surface. When creating surface, VA_RT_FORMAT will be used firstly to choose the expected fourcc/media_format for the surface. And the fourcc will be revised by the value of VASurfaceAttribPixelFormat. Add vaapi_format_map support for new pixel_format Y210. This is fundamental for both VA-API and QSV. Signed-off-by: Linjie Fu <linjie.fu@intel.com>

* lavu/tx: improve 3-point fixed precisionLynne2020-02-14
| | | | | There's just no reason not to when its so easy (albeit messy) and its also reducing the precision of all non-power-of-two transforms that use it.

* lavu/tx: implement 32 bit fixed point FFT and MDCTLynne2020-02-13
| | | | | | | | | | | | | | | | | | | | Required minimal changes to the code so made sense to implement. FFT and MDCT tested, the output of both was properly rounded. Fun fact: the non-power-of-two fixed-point FFT and MDCT are the fastest ever non-power-of-two fixed-point FFT and MDCT written. This can replace the power of two integer MDCTs in aac and ac3 if the MIPS optimizations are ported across. Unfortunately the ac3 encoder uses a 16-bit fixed point forward transform, unlike the encoder which uses a 32bit inverse transform, so some modifications might be required there. The 3-point FFT is somewhat less accurate than it otherwise could be, having minor rounding errors with bigger transforms. However, this could be improved later, and the way its currently written is the way one would write assembly for it. Similar rounding errors can also be found throughout the power of two FFTs as well, though those are more difficult to correct. Despite this, the integer transforms are more than accurate enough.

* lavu/tx: mention FFT output is not normalizedLynne2020-02-08
| | | | | | | Not even FFTW's output is normalized. This should prevent at least some users from complaining that doing a forward transform followed by an inverse transform has a mismatching output to the original input.

* lavu: add Vulkan hwcontext codeLynne2020-02-04
| | | | | | | | | | This commit adds the necessary code to initialize and use a Vulkan device within the hwcontext libavutil framework. Currently direct mapping to VAAPI and DRM frames is functional, and transfers to CUDA and native frames are supported. Lets hope the future Vulkan video decode extension fits well within this framework.
* lavu/hwcontext: Add support for HW -> HW transfersPhilip Langdale2020-02-04
| | | | | | | | | | | | | | | | | | | | We are beginning to consider scenarios where a given HW Context may be able to transfer frames to another HW Context without passing via system memory - this would usually be when two contexts represent different APIs on the same device (eg: Vulkan and CUDA). This is modelled as a transfer, as we have today, but where both the src and the dst are hardware frames with hw contexts. We need to be careful to ensure the contexts are compatible - particularly, we cannot do transfers where one of the frames has been mapped via a derived frames context - we can only do transfers for frames that were directly allocated by the specified context. Additionally, as we have two hardware contexts, the transfer function could be implemented by either (or indeed both). To handle this uncertainty, we explicitly look for ENOSYS as an indicator to try the transfer in the other direction before giving up.
