qtc validates projects first. if error occurs, visual items after error
can not be displayed in qtc
ios MAKEFILE_GENERATOR is XCODE(why) which not supported by configure.prf
and error() is called, so qtc displayed nothing
changes:
You have to include <QtAVWidgets/QtAVWidgets.h> to use built-in widget
renderers
Link against QtAVWidgets
TODO:
QT += avwidgets not available
move ids to widgets module?
Changelog:
- More QtMultimedia compatible QML playback API
- Debian package support. Now you can build on

- players: config UI in QMLPlayer. Video preview on
progress bar.
Changelog:
- Improve OpenGL: more pixel formats, supports QML(not stable),
dynamic gl support etc.
- VAAPI: GLX direct rendering support. check 4k.

- 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

* 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

1. memory leak
2. sometimes crash. can not open 2 players, or other players using hw.
Assertion abs(src_linesize) >= bytewidth failed at libavutil/imgutils.c:
