The patch series depends on the qv4l2 ALSA and OpenGL patch series.
This adds scaling and aspect ratio support to the qv4l2 CaptureWin.
It also fixes some issues with the original OpenGL patch series,
as well as adding tweaks and improvements left out in the original patches.
Some of the changes/improvements:
- CaptureWin have scaling support for video frames for all renderers
- CaptureWin support pixel aspect ratio scaling
- Aspect ratio and scaling can be changed during capture
- CaptureWin's setMinimumSize is now resize, which resizes the window to the frame size given
and minimum size is set automatically
- The YUY2 shader programs are rewritten and has the resizing issue fixed
- The Show Frames option in Capture menu can be toggled during capture
- Reset and disable scaling options
- Added a hotkey:
CTRL + F : (size to video 'F'rame)
When either the main window or capture window is selected
this will reset the scaling to fit the frame size.
This option is also available in the Capture menu.
Pixel Aspect Ratio Modes:
- Autodetect (if not supported this assumes square pixels)
- Square
- NTSC/PAL-M/PAL-60
- NTSC/PAL-M/PAL-60, Anamorphic
- PAL/SECAM
- PAL/SECAM, Anamorphic
