What is it?
The point of the mythtv-vid branch is to fix some of the long standing deficiencies in the video output classes, for X11 in particular.
Development can be tracked via #2287
Goals
Filters
- Add support for OpenGL filtering, in particular Lanczos for scaling and YV12->RGB conversion for display (ref #843)
- Allow different filter sets for different video and display resolutions.
- Make setting up filters easier with a GUI
- Allow changing the filter set during playback, esp for deinterlacing.
- Auto-detect pull-up and apply ivtc filtering (#1778)
Video output methods
- Implement per-frame video resolution switching
- Support XvMC for MPEG-2 NUV files (and enable transcode to MPEG-2)
- Finish support for XvMC copy to pbuffer + opengl render
- Key xrandr switching to video framerate
OSD rendering
- Fix video frame OSD blending for bob-deint (Filter vert freq in pause + when there is video<->screen framerate mismatch)
- Implement RGB OSD surfaces
- Implement OpenGL OSD surfaces
- Implement X Composited OSD surfaces
- Key preferred OSD and OSD fade to resolution and video output method.
