Hi,
as you may know I am the initial author of kwintv.
After a long period of non-developing on kwintv I deceided to continue...
I heard from George Staikos that you plan to rewrite
kwintv (based on qtvision and the old kwintv).
After some mails with George we agreed that I should
rewrite the basic parts of kwintv (the interface to the
video hardware).
Now I want to present you some parts of my work I have done
so far and get some comments etc. from you.
I think the interface is worth being discussed...
Okay, here is a short description:
-- VDev -- hardware abstraction layer
The base class VDev defines an abstract interface
to access the functionality of a video device (e.g.
video4linux, video4linux2, X11 XVideo extension etc.).
Till now there are three classes inherieting VDev:
V4LDev, V4L2Dev and XVDev.
As the name suggests, V4LDev is the implementation
for video4linux, V4L2Dev for video4linux2 and
XVDev for X11 XVideo extension.
XVDev is completely untested till now, also
V4L2Dev.
-- tvWidget -- QWidget abstraction layer
The second base class tvWidget defines a QWidget based
widget that can display the images delivered by a
video device in several ways.
The class tvWidgetOl inheriets tvWidget and can
display image data from a VDev device which is capable
of doing hardware overlay and image clipping
(@rev VDev::canOverlay and @rev VDev::canClipping ).
So you can use V4LDev and V4L2Dev as input devices,
if they support overlay and clipping. The overlay
code is a bit tricky since it must handle some
of the X11 events.
Status: tested, but there are some problems with tooltips.
The class tvWidgetGrab inheriets tvWidget and
can display image data from any VDev that is
capable of grabbing a single image (either
using read() or some sort of "grab to memory").
If the video device does not support the
palette X11 uses for your display, the image
data must be converted (and/or rescaled...).
You can use V4LDev and V4L2Dev as input devices.
If you have support for hardware image scaling,
you can use a XVDev (with XVDev::isXvImageScaler()
== true) for hardware scaling.
Supporting classes are xImage (inherieted by
x11Image and xvImage). x11Image and xvImage use
basic X11 functions for image display since QImage
and QPixmap have a slow interface and do not support
XVideo. With a fairly fast processor you get up to
25 fps (PAL) / 29.x fps (NTSC). tvWidgetGrab uses
an extra QThread so the QApplication queue will
not be blocked by the image processing.
Status: basic functionality tested, image
converting untested.
The class tvWidgetXv inheriets tvWidget and
uses a XVDev as input device. XVideo does
overlay, too, but all the tricky things are
done by X11 itself, so the implementation
of tvWidgetXv is very simple.
tvWidgetXv is untested till now.
Status: completely untested.
-- vbiDecoder --- videotext decoder
I also worked on an imlementation of a videotext
widget based on the libvbi in the xawtv project
(libvbi is originally based on AlevT).
I added the interface definitons of VDev and tvWidget
as attachments.
