The gcc altivec extension defines keywords for vector, bool, and pixel,
both with underscores and without. However, unless another extension is
used the keywords without underscores conflict with standard types.
To resolve the conflict use the keywords with underscores for the
altivec vector types.
Fixes: #2711

* - added ffmpeg stuff to cmake
* - added observer_ptr
* ffmpeg utils
* WIP
* - added ffmpeg_decoder
* config file for test data
* another test file
* install ffmpeg
* added ffmpeg_demuxer
* install all ffmpeg libraries
* support older version of ffmpeg
* simplified loop
* - test converting to dlib object
- added docs
- support older ffmpeg
* added convert() overload
* added comment
* only register stuff when API not deprecated
* - fixed version issues
- fixed decoding
* added tests for ffmpeg_demuxer
* removed unused code
* test GIF
* added docs
* added audio test
* test for audio
* more tests
* review changes
* don't need observer_ptr
* made deps public. I could be wrong but just in case.
* - added some static asserts. Some areas of the code might do memcpy's on arrays of pixels. This requires the structures to be packed. Check this.
- added convert() functions
- changed default decoder options. By default, always decode to RGB and S16 audio
- added convenience constructor to demuxer
* - no longer need opencv
* oops. I let that slip
* - made a few functions public
- more precise requires clauses
* enhanced example
* - avoid FFMPEG_INITIALIZED being optimized away at link time
- added decoding example
* - avoid -Wunused-parameter error
* constexpr and noexcept correctness. This probably makes no difference to performance, BUT, it's what the core guidelines tell you to do. It does however demonstrate how complicated and unecessarily verbose C++ is becoming. Sigh, maybe one day i'll make the switch to something that doesn't make my eyes twitch.
* - simplified metadata structure
* hopefully more educational
* added another example
* ditto
* typo
* screen grab example
* whoops
* avoid -Wunused-parameter errors
* ditto
* - added methods to av_dict
- print the demuxer format options that were not used
- enhanced webcam_face_pose_ex.cpp so you can set webcam options
* if height and width are specified, attempt to set video_size in format_options. Otherwise set the bilinear resizer.
* updated docs
* once again, the ffmpeg APIs do a lot for you. It's a matter of knowing which APIs to call.
* made header-only
* - some Werror thing
* don't use type_safe_union
* - templated sample type
- reverted deep copy of AVFrame for frame copy constructor
* - added is_pixel_type and is_pixel_check
* unit tests for pixel traits
* enhanced is_image_type type trait and added is_image_check
* added unit tests for is_image_type
* added pix_traits, improved convert() functions
* bug fix
* get rid of -Werror=unused-variable error
* added a type alias
* that's the last of the manual memcpys gone. We'using ffmpeg API everywhere now for copying frames to buffers and back
* missing doc
* set framerate for webcam
* list input devices
* oops. I was trying to make ffmpeg 5 happy but i've given up on ffmpeg v5 compatibility in this PR. Future PR.
* enhanced the information provided by list_input_devices and list_output_devices
* removed vscode settings.json file
* - added a type trait for checking whether a type is complete. This is useful for writing type traits that check other types have type trait specializations. But also other useful things. For example, std::unique_ptr uses something similar to this.
* Davis was keen to simply check pixel_traits is specialised. That's equivalent to checking pixel_traits<> is complete for some type
* code review
* juse use the void_t in dlib/type_traits.h
* one liners
* just need is_image_check
* more tests for is_image_type
* i think this is correct
* removed printf
* better docs
* Keep opencv out of it
* keep old face pose example, then add new one which uses dlib's ffmpeg wrappers
* revert
* revert
* better docs
* better docs

* Added bind_front()
* - Added bind_back()
- moved contents of invoke.h into functional.h
- invoke.h just includes functional.h
- added tests
* though it doesn't make a difference, use correct header
* add docs
* Give this a try. Might make gcc7 happy
* workaround for gcc7 bug
