Changelog:
- Add QtAVWidgets module contains widget based renderers, video preview
widget
- QtAV module only depends on QtCore and QtGui
- Improve audio output API
- Simplify deployment on OSX. Deploy sdk from release packages without
build.

Changelog:
- Async load
- Faster seek and preview. Thanks wm4(mpv developer)
- Better a/v sync solution. Now can play high fps video better than ANY
other players.
- DXVA: enable HEVC decoder if libavcodec runtime supports. LAVFilters
ffmpeg supports it.
- Cedarv improvements, nv12 output support, neon code from libvdpau-
sunxi
- Multiple OpenAL instances support
- AVInput class to extend media sources. Support play from qrc resouces.
- Display the first frame after seek
- Better clock error correction
- Fix play frame by frame issues
- Fix QML video shake
- More details for error signals
- Apply user options in the next playback
- Dynamic load libass (submodule 'capi' is required)
- VA-API: fix blurred bottom line issue. works on libav >= 9 now.
- Progress is start at 0 by default even if 1st pts is not 0.
- Fix capture issues: capture current displayed frame, easier api
- RGB48 support. OpenGL only supports RGB48LE.
- Link to static ffmpeg support
- Fix open error if input url/path contains special charactors
Changelog:
- Improve OpenGL: more pixel formats, supports QML(not stable),
dynamic gl support etc.
- VAAPI: GLX direct rendering support. check 4k.
- DXVA: more decoding surfaces to improve performance
- VDA (OSX hardware decoding) support
- Android support. Easy to deploy
- Subtitle support, including QML
- Improve OpenAL. Works fine on most platforms including android
- FFmpeg libavfilter support
- Audio output api change
- deploy script for ifw, OSX
- Bug fix
- WIP: dsound, opensl, audio engine, audio filters etc.
Changelog:
- CUDA: better quality and performance, Fix wrong display order. No
Mosaics.
- vaapi and dxva support SSE4.1 to copy decoded frame for intel gpu.
vaapi was added months ago, but the performance was very poor. With the
help of SSE4.1 we have greate performance improvement.
- VAAPI supports drm
- Use latest FFmpeg's hw api
- Fix wrong display or crash if change HW decoder
- Add some options for AVCodec and AVFormat as decoder's meta
properties.
- Metadata support
- Display aspect ratio use the value in stream if defined. Thank Sandro
Cavazzoni
- Support install QtAV as a Qt module
- Fix wrong file name encoding.
- Display the image in a music file
- OpenGL improvement and better performance(works on iOS and Android):
* enable GLSL if supported
* use GLSL to render YUV frames
* GLSL based video equalizer
- XV bug fix and improvement. Supports NV12. Supports video equalizer.
- Play from QIODevice support
- Capture YUV frames support.
- Fix wrong duration in OSD
- CUDA decoder working in progress
- player:
* no gui blocking while opening a stream
* add config dialog
- Regressions:
* OpenGL can not display H10p
Changelog:
- Selectable audio track
- Multiple rendering target for 1 video support
- Hardware decoding support(unstable): DXVA2 for windows, VA-API for
x11(bad performance now)
- Region of Interest(ROI) support, i.e. crop.
- Filter support(Experimental)
- Video eq: brightness, contrast, saturation
- Repeat support
- Mang api changes
- QML: compatible with many QtMultiMedia APIs
- build/install: check arch, fix wrong rpath and launch error on Mac,
add installer
- player: playlist, history, better online tv, etc.
Changelog:
- FFmpeg/libav avresample support
- OpenGL ES2 support. Can build against Qt5 GLES2 version now
- XV support for Qt5
- more audio format support, e.g. sample format, channels.
