* - 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 --------- Co-authored-by: pf <pf@me> |
