* hwcontext: add av_hwdevice_ctx_create_derived_optsLynne2020-05-23
| | | | | | | | | | | | | 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).

* avcodec/options_table: make AVCodecContext->profile search for child constantsMarton Balint2020-05-22
| | | | | | | | | This change makes it possible for child encoders to define custom profile option names which can be used for setting the AVCodecContext->profile. Also rename unit name to something rather unique, so it won't be used elsewhere. Signed-off-by: Marton Balint <cus@passwd.hu>
* avutil/opt: add AV_OPT_FLAG_CHILD_CONSTSMarton Balint2020-05-22
| | | | | | | | 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>

* avcodec: Add MediaFoundation encoder wrapperwm42020-05-19
| | | | | | | | | | | | | | | This contains encoder wrappers for H264, HEVC, AAC, AC3 and MP3. This is based on top of an original patch by wm4 <nfxjfg@googlemail.com>. The original patch supported both encoding and decoding, but this patch only includes encoding. The patch contains further changes by Paweł Wegner <pawel.wegner95@gmail.com> (primarily for splitting out the encoding parts of the original patch) and further cleanup, build compatibility fixes and tweaks for use with Qualcomm encoders by Martin Storsjö.

* doc/muxers: Document title tag for attachmentsAndreas Rheinhardt2020-05-19
| | | | | | | | | The Matroska muxer has always mapped the title tag to the FileDescription element for attachments streams since support for writing attachments was added in commit c7a63a521b5c165405e3577751d649529d09f0c5.

* libavutil: add API for exporting video frame quantizersJuan De León2020-05-12
| | | | | | | | | | | | | | | 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 extensionsLynne2020-05-10
| | | | | | | 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.

| | | | | | Also documents all options supported by the hwdevice. This lets users enable all extensions they need without writing their own instance initialization code.
* doc/encoders: remove unsubstantiated ffaacenc > fdk-aac claimLou Logan2020-05-08
| | | | | | | | | | | | | | | | | | | After this claim was made in e34e361 kamedo2 did an in-depth ABX test comparing these encoders: https://hydrogenaud.io/index.php?topic=111085.0 Result: FFmpeg AAC wasn't as good as libfdk_aac on average. I know some things have changed since then such as, "use the fast coder as the default" (fcb681ac) for example, so maybe the situation is different now. However, I am unaware of any recent comparison. So without any substantiation we shouldn't make such a blantant claim.
