* avutil/frame: Treat frame as uninitialized in get_frame_defaults()Andreas Rheinhardt2021-12-05
| | | | | | | | | | | | | | Currently, it also tests whether extended_data points to something different than the AVFrame's data array and frees extended_data if it is different. Yet this is only necessary for one of its three callers, namely av_frame_unref(); meanwhile the other two callers took measures to avoid this (or rather, to make it to an av_free(NULL)). This commit moves this chunk to av_frame_unref() (so that get_frame_defaults() now treats its input as uninitialized) and removes the now superfluous code in the other two callers.

* lavu/frame: clarify doxyAnton Khirnov2021-12-04
| | | | | AVFrame.data[] elements not used by the format should ALWAYS be null, hwaccel formats are not an exception.

| | | | All frames we deal with should always be refcounted now.
* libavutil/hwcontext_qsv: fix a bug for mapping vaapi frame to qsvnyanmisaka2021-12-04
| | | | | | | | | | | | | | The data stored in data[3] in VAAPI AVFrame is VASurfaceID while the data stored in pair->first is the pointer of VASurfaceID, so we need to do cast to make following commandline works: ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 \ -hwaccel_output_format vaapi -i input.264 \ -vf "hwmap=derive_device=qsv,format=qsv" -c:v h264_qsv output.264 Signed-off-by: nyanmisaka <nst799610810@gmail.com> Signed-off-by: Wenbin Chen <wenbin.chen@intel.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>

| | | | | | | | | | Validation layer is an indispensable part of developing on Vulkan.

* hwcontext_vulkan: check for non-flagged transfer queue familiesLynne2021-11-20
| | | | | | | | | "All commands that are allowed on a queue that supports transfer operations are also allowed on a queue that supports either graphics or compute operations. Thus, if the capabilities of a queue family include VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT, then reporting the VK_QUEUE_TRANSFER_BIT capability separately for that queue family is optional."
* lavu/vulkan: check for initialization when freeing buffersLynne2021-11-20
| | | | | | | | | What happens on startup is that ffmpeg.c initializes the filter, then frees it without feeding a single frame through. With no input frame, the filter lacks a hardware device. The rest of the uninit code checks if Vulkan objects exist, which they must if there's a hardware device, but vk->DeviceWaitIdle does not require an object. So, add a check for it.

* lavfi/vulkan: split off lavfi-specific code into vulkan_filter.cLynne2021-11-19
| | | | | | | | | | | | | | | | | The issue is that libavfilter depends on libavcodec, and when doing a static build, if libavcodec also includes "libavfilter/vulkan.c", then during link-time, compiling programs will fail as there would be multiple definitions of the same symbols in both libavfilter and libavcodec's object files. Linkers are, however, more permitting if both files that include a common file that's used as a template are one-to-one identical. Hence, to make both files the same in the future, export all avfilter specific functions to a separate file. There is some work in progress to make templated files like this be compiled only once, so this is not a long-term solution. This also removes a macro that could be used to toggle SPIRV compilation capability on #include-time, as this could cause the files to be different.

* avutil/hwcontext_qsv: Remove redundant checkAndreas Rheinhardt2021-11-18
| | | | | | | | | | | | | It has already been checked immediately before that said AVDictionaryEntry exists; checking again is redundant. Furthermore, av_hwdevice_find_type_by_name() requires its argument to be non-NULL, so adding a codepath that automatically calls it with that parameter is nonsense. The same goes for the argument corresponding to %s. Fixes Coverity issue 1491394. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* aarch64: Add Armv8.5-A BTI supportJonathan Wright2021-11-16
| | | | | | | | | | | | | | | | | Add Branch Target Identifiers (BTIs) to all functions defined in AArch64 assembly files. Most of the BTI landing pads are added automatically by the 'function' macro. BTI support is turned on or off at compile time based on the presence of the __ARM_FEATURE_BTI_DEFAULT feature macro. A binary compiled with BTI support can be executed on an Armv8-A processor without BTI support because the instructions are defined in NOP space.

* libavutil/common: clip nan value to aminMark Reid2021-11-15
| | | | | | | | | | | | Changes av_clipf to return amin if a is nan. Before if a is nan av_clipf_c returned nan and av_clipf_sse would return amax. Now the both should behave the same. This works because nan > amin is false. The max(nan, amin) will be amin. Signed-off-by: James Almer <jamrial@gmail.com>
* */version.h: define FF_API macros unconditionallyAnton Khirnov2021-11-15
