This patch implements a simple Qt-based media player which is actually a
graphical user interface for the SDL-based 'avplay' media player from
'libav'. It starts 'avplay' as a child and shows its graphical output in a
'QNitpickerViewWidget'. The widgets for controlling the player state send
the according keyboard and mouse input events to 'avplay'.
The 'qt_avplay' player supports the following configuration options:
<mediafile name="..."/>
-> name of the media file to play
<framebuffer_filter name="..." ram_quota="..."/> (may appear multiple times)
-> name of a framebuffer filter service to filter the video output
Fixes#222.
With this patch the Genode thread used by the QThread class gets deleted
when 'QThread::wait()' gets called and the timeout didn't trigger or when
'QThread::terminate()' gets called.
Fixes#193.
The old variant provided 8K capability slots to all processes on core,
which increased binaries by 180 KB for the static allocator. I reduced it
to 4K capabilities stay under 100 KB overhead for the allocator.
Anyway, pci_drv and pl11x_drv need more RAM quota now: 2M for pl11x_drv
and 1M for pci_drv.
- Remove example application source code files which also exist in contrib
- Outsource commonly used parts from target.mk files
- Store the current Qt version only in one place
- Add run scripts for the example applications
Fixes#127.
As a preliminary step for working on issue #11, this patch revisits the
'Framebuffer::info' RPC call. Instead of using C-style out paramters,
the new 'mode()' RPC call returns the mode information as an object of
type 'Mode'. Consequently, mode-specific functions such as
'bytes_per_pixel' have been moved to the new 'Framebuffer::Mode' class.
