* hwcontext: add av_hwdevice_ctx_create_derived_optsLynne2020-05-231-0/+3
| | | | | | | | | | | | | This allows for users who derive devices to set options for the new device context they derive. The main use case of this is to allow users to enable extensions (such as surface drawing extensions) in Vulkan while deriving from the device their frames are on. That way, users don't need to write any initialization code themselves, since the Vulkan spec invalidates mixing instances, physical devices and active devices. Apart from Vulkan, other hwcontexts ignore the opts argument since they don't support options at all (or in VAAPI and OpenCL's case, options are currently only used for device selection, which device_derive overrides).

| | | | | | | | This will be used for AVCodecContext->profile. By specifying constants in the encoders we won't have to use the common AVCodecContext options table and different encoders can use the same profile name even with different values. Signed-off-by: Marton Balint <cus@passwd.hu>

* libavutil: add API for exporting video frame quantizersJuan De León2020-05-121-0/+4
| | | | | | | | | | | | | | | This is intended to replace the deprecated the AV_FRAME_DATA_QP_TABLE* API and extend it to a wider range of codecs. In the future, it may also be extended to support other encoding parameters such as motion vectors. Additional changes by Anton Khirnov <anton@khirnov.net> with suggestions by Lynne <dev@lynne.ee>.

* hwcontext_vulkan: expose enabled device and instance extensionsLynne2020-05-101-0/+4
| | | | | | | This solves a huge oversight - it lets users reliably use their own AVVulkanDeviceContext. Otherwise, the extensions supplied and enabled are not discoverable by anything outside of hwcontext_vulkan. Also clarifies that any user-supplied VkInstance must be at least 1.1.

* avcodec: Add explicit capability flag for encoder flushingPhilip Langdale2020-04-151-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, there was no way to flush an encoder such that after draining, the encoder could be used again. We generally suggested that clients teardown and replace the encoder instance in these situations. However, for at least some hardware encoders, the cost of this tear down/replace cycle is very high, which can get in the way of some use-cases - for example: segmented encoding with nvenc. To help address that use case, we added support for calling avcodec_flush_buffers() to nvenc and things worked in practice, although it was not clearly documented as to whether this should work or not. There was only one previous example of an encoder implementing the flush callback (audiotoolboxenc) and it's unclear if that was intentional or not. However, it was clear that calling avocdec_flush_buffers() on any other encoder would leave the encoder in an undefined state, and that's not great. As part of cleaning this up, this change introduces a formal capability flag for encoders that support flushing and ensures a flush call is a no-op for any other encoder. This allows client code to check if it is meaningful to call flush on an encoder before actually doing it. I have not attempted to separate the steps taken inside avcodec_flush_buffers() because it's not doing anything that's wrong for an encoder. But I did add a sanity check to reject attempts to flush a frame threaded encoder because I couldn't wrap my head around whether that code path was actually safe or not. As this combination doesn't exist today, we'll deal with it if it ever comes up.

* avformat/avformat: Update av_read_frame() documentationAndreas Rheinhardt2020-03-291-0/+4
| | | | | | | | | | | | | This commit updates the documentation of av_read_frame() to match its actual behaviour in several ways: 1. On success, av_read_frame() always returns refcounted packets. 2. It can handle uninitialized packets. 3. On error, it always returns blank packets. This will allow callers to not initialize or unref unnecessarily.

* avcodec/avcodec, avpacket: Return blank packet on av_packet_ref() failureAndreas Rheinhardt2020-03-281-0/+4
| | | | | | | | | | | | Up until now, it was completely unspecified what the content of the destination packet dst was on error. Depending upon where the error happened calling av_packet_unref() on dst might be dangerous. This commit changes this by making sure that dst is blank on error, so unreferencing it again is safe (and still pointless). This behaviour is documented.

* lavu/tx: implement 32 bit fixed point FFT and MDCTLynne2020-02-131-0/+3
| | | | | | | | | | | | | | | | | | | | 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: add Vulkan hwcontext codeLynne2020-02-041-0/+4
| | | | | | | | | | 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.
