First release candidate of 1.0

This is the first release candidate of DirectFB 1.0! The API has been frozen and the final release is expected this year. Other packages will be updated within a few days. Click on the news title for an overview of changes.
API

* Added DIEF_FOLLOW to DFBInputEventFlags which indicates that another event will follow immediately. In the mouse driver this is used to "link" the x/y axis motion events. The window manager no longer sends two motion events (x/0, 0/y) for one x/y mouse movement (x and y axis at once). Zig-zag cursor/window movement and double event/update rate are gone.
* Moved DirectFBGL header to the proper location. We need the header here since the DirectFBGL interface is strongly integrated within DirectFB and we want to support external implementations.
* More Porter/Duff rules (SRC_ATOP,DST_ATOP,ADD,XOR).
* Added DFB_SUSPENDED error meaning "The requested object is suspended!".
* Added 4 bit packed alpha pixel format DSPF_A4, e.g. for fonts.
* Added support for the 18bpp format family.

API | IDirectFBDisplayLayer

* Added SwitchContext() that switches between the shared and the exclusive context if present.
* Added SetClipRegions() that, if supported by hardware, sets the clipping regions that are used to to enable or disable visibility of parts of the layer. The number of regions is stated in the display layer description. The layer will be shown only in these regions or except in these regions.

API | IDirectFBFont

* Added GetStringBreak() to break a text line by line. Thanks to sridewa <sridewa@gmail.com>.
* Added EnumEncodings() enumerating all provided encodings, also see Fonts section below.
* Added FindEncoding() to look up an encoding directly by its name.
* Added SetEncoding() for choosing the encoding for local interface methods and as a default for the surfaces.

API | IDirectFBImageProvider

* Added DIRenderCallbackResult to DIRenderCallback to be able to abort rendering.

API | IDirectFBInputDevice

* Added DetachEventBuffer() to detach an event buffer explicitly.

API | IDirectFBScreen

* Allow connectors to be selected at the encoders without the need to define outputs, add slow blanking, thanks to Daniel J Laird <danieljlaird@hotmail.com>.
* Populating screen API a bit more, thanks to Daniel Laird <danieljlaird@hotmail.com>.
* Added GetSize().

API | IDirectFBSurface

* Added ReleaseSource() to release a possibly attached source, e.g. after blitting from it only once and from nothing else afterwards.
* Added GetFramebufferOffset() returning the offset within the graphics memory, thanks to Stefan Lucke <stefan@lucke.in-berlin.de>.
* Added GetPosition() returning the offset of a sub surface.
* Finally decided to catch horizontal/vertical lines in DrawLine() and optimize them using rectangle filling.
* Added SetEncoding() to choose an encoding for the text routines, will be overwritten by SetFont() which takes the default encoding of the new font, also see Fonts section below.

API | IDirectFBVideoProvider

* Removed return value from DVFrameCallback.
* Added SetPlaybackFlags(), SetSpeed() and GetSpeed().
* Added SetVolume() and GetVolume().

API | IDirectFBWindow

* Added DetachEventBuffer() to detach an event buffer explicitly.

Build Options

* Added option --enable-netork to enable/disable building network protocols handlers.

Fonts

* Added support for other encodings than UTF8. Encodings are (or can be) provided with each font implementation. This model reduces code sharing slightly, but allows higher efficiency via optimized combination of decoding and translation.
* Every encoding just has a name and an ID, where the name can be chosen freely, except for DTEID_UTF8 which is always available and has the name "UTF8".
* Implemented UTF8 and "Latin1" encoding in FT2 font loader. Nice demonstration how different encodings can be used, while still having a single glyph cache, which is no longer based on character codes, but on their raw indices.
* See ChangeLog from 2006-05-06 for more details.

Graphics Core

* Added DFBResult return value to graphics driver's EngineSync() and WaitSerial() to be able to return DFB_TIMEDOUT or other errors. In these cases the core resets the accelerator via EngineReset() and takes care of state invalidation etc.
* dfb_gfxcard_sync() and dfb_gfxcard_waitserial() also lease the graphics property, i.e. there are no more concurrent calls to the driver, e.g. FillRectangle() along with EngineSync().
* Moved clipping from dfb_clip_stretchblit() to gStretchBlit() doing all clipping, phase and offset calculations in place, otherwise clipping suffered from rounding and off-by-one errors due to going back to integer in between.
* In case of no hardware clipping but rectangle filling, if in DrawRectangle() the whole rectangle outline was outside the clipping area, the clipping area was drawn in the software fallback code.
* In dfb_surfacemanager_deallocate() make sure no hardware read or write access on the buffer is pending before freeing the chunk.
* Added global function pointer __DFB_CoreRegisterHook with __DFB_CoreRegisterHookCtx to allow application level layer (and screen) implementations building on top of existing layers.
* New capabilities for setting destination size limit. If the rectangle is too big, first try clip, then try again and eventually fall back to software.
* Implemented font cache limit, currently hardcoded to five rows, each row stores a number of glyphs. When the maximum number is reached it will reuse the least recently used row, kicking out all glyphs that have been on it.
* Before every graphics operation, i.e. in dfb_gfxcard_state_check(), clip the state's clipping region to the destination surface dimension.

Input Core

* First and fully working implementation of dead key handling using static tables for mapping of dead keys and following symbols to the combined symbol.

Surface Core

* Some changes that decrease system memory usage for surface buffers, especially where graphics memory is available.
* Allocate system instance of auto-video buffers on first access, not immediately during creation of the surface.
* Deallocate system memory when buffer is written to in video memory. Reallocate it if the buffer is kicked out of video memory.
* Implemented "suspended" surface buffers, temporarily deallocated. No valid instance at all until it's resumed.
* Added dfb_surface_buffer_suspend/resume().
* Added SBF_SUSPENDED.
* Align pitch of system memory buffers to be a multiple of 8 instead 4.
* Add extra 16 bytes at the end of a buffer as a dummy area for optimized routines, e.g. to avoid segfaults due to prefetching.

Window Core

* Rewritten cursor handling (software cursor) to use a surface instead of a window. The window manager module gets notified about all kinds of updates regarding the cursor. All window manager modules use the same code for now, using backing store for the region under the cursor. This avoids revealing window content that hasn't been commited via Flip(), yet. It should also be faster as it no longer depends on the windows that are covered by the cursor.
* Check if window is destroyed and return DFB_DESTROYED in all functions which would have called the WM, because a destroyed window is no longer known to the WM and the WM's window data structure is deallocated.

Software Renderer

* Fix unaligned 32 bit accesses in color keying code.
* Allocate the accumulator only if it will be used.
* Check if palettes are equal when blitting indexed formats.

Misc

* Added dfb_rectangle_subtract() to subtract insets from rectangle.
* Added DFB_RECTANGLE_CONTAINS_POINT and DFB_REGION_CONTAINS_POINT macros.
* Added dfb_gfx_copy_to() as an extension of dfb_gfx_copy(). The advantages are different x/y offset for source/destination and blitting from back buffer. The latter was a must for the backing store based software cursor.

libdirect

* Reworked Direct/Stream to gain more efficiency, added several optional network protocols.
* Added direct_stream_mime() that returns mime description of the stream.
* In addition to DIRECT_FORCE_DEBUG one can use DIRECT_ENABLE_DEBUG now.
* Only duplicate used portion of array in direct_trace_copy_buffer(), set limit from 256 to 200.
* Added BSWAP16 and BSWAP32 macros, direct_base64_encode, direct_base64_decode and direct_md5_sum.
* Due to increasing amount of debug messages the default is "no-debug" now. It makes more sense to only enable wanted debug domains by hand, e.g. "debug=core/font". Otherwise, "debug" option still works, too.
* Replaced direct_stream_fopen() by direct_stream_fileno().
* Added direct_stream_dup() to increase the stream's reference counter.
* In the stack trace show base address of each file to allow offset calculation 'by hand' within dynamically loaded modules, i.e. where ldd doesn't help.

libfusion

* Local 'local reactions' are no longer processed before dispatching further via the kernel device. This causes all local reactions within each Fusionee to be called by the Fusion Dispatcher only, in chronological order. It's a fundamental change in runtime behaviour which might break some code that relies on the synchronous execution of the dispatcher's own local reactions.
* Implemented experimental fork() handling in Fusion. Added FusionForkAction being FFA_CLOSE by default, which can be changed to FFA_FORK with a call to fusion_world_set_fork_action() for each Fusionee/World.
* Added "name" parameter to fusion_ref_init() like others already have.
* Return DFB_LOCKED in fusion_ref_up() if EAGAIN is received (ref is zero locked).
* New shared hash table implementation and property support for object.
* Added fusion_skirmish_lock_count() returning the lock counter if held by the caller.
* Added fusion_reactor_destroy() like fusion_reactor_free() but without freeing the shared structure etc.
* No longer (need to) access the shared structure during local message processing in the Fusion dispatcher.

i830 driver

* Fixed overlay destination color keying for 8/15/16 bit primary layer formats, add "i8xx_overlay_pipe_b" option, thanks to Stefan Lucke <stefan@lucke.in-berlin.de>.

Matrox driver

* Added field based blitting support.
* Added DSCAPS_SEPARATED support to BES, CRTC2 and SPIC.
* Fixed pixelpitch alignment for YUY2/UYVY.
* PAL-60 support (or at least close enough for Ville's TV).

nVidia driver

* Avoid to set the overlay memory limit, it's already done by the kernel.
* Basic acceleration for ALUT44.
* Disable host-to-video hardware blit for simple blits without format conversion.
* Added nvEngineReset().

Radeon driver

* R300: Support FillTriangle() and DSDRAW_BLEND.
* RV250: Dropped YUV->RGB support.
* Enable VC_32BIT_SWAP on big-endian machines.
* Removed (erroneously set) flag VF_RADEON_MODE in r200DoDrawRectangle3D().
* Added patch to radeonfb fixing support for R300 chipsets (it also adds new devices).
* Use different settings for R300 and non-R300 when setting MC_FB_LOCATION.
* Added the possibility to use the graphics layer as an OSD. It works exactly the same way as in the unichrome driver: Set the video layer level to -1 and enable DLOP_ALPHACHANNEL on the graphics layer.
* Applied patch by Christer Palm <christer.palm@pulsen.se>: fixes word swapping on PPC.

Unichrome driver

* Disable hardware cursor in VIA_REG_CURSOR_MODE. Thanks to Michel van Noorloos <michel.van.noorloos@sioux.nl>.
* Added PCI ID for CN700.

DynaPro input driver

* New 3M DynaPro Touchscreen driver, thanks to Pдr Degerman <parde@ikp.liu.se>!

Keyboard input driver

* Added support for dead keys.

Linux Input input driver

* Added support for dead keys.

DFIFF image provider

* New DirectFB Fast Image File Format with a fast image provider module and a tool to convert images from PNG to DFIFF.

GIF image provider

* Dropped support for GIF87 (can't be animated).

GIF video provider

* New animated GIF video provider.

V4L video provider

* Fixed planar data copy.
* Added more pixelformats for v4l2.

FBDev System

* Clean up error handling in system_initialize() and fix bug with shared memory (de)allocation.
* Treat fbdev format 8/16,8/8,8/0,0/0 as ARGB when ARGB was requested (that because framebuffer drivers tend to ignore the alpha channel).
* Don't touch console blanking when using graphics-vt.

SDL System

* Better keymap emulation.
* Fake video modes by reading fb.modes, just like the fbdev backend.

directfb-csource tool

* Added option --rgbformat which in contrast to the --format option only is effective if the image doesn't require an alpha channel. That's useful e.g. with RGB16 for opaque and ARGB for blended images, when the primary format will be RGB16. So far directfb-csource either used ARGB/RGB32 automatically, or it always used RGB16 or whatever you specified via --format.
* Make structs and pixel data const, helps with use in shared libs.

fx tool

* Very basic program to emulate/illustrate the pixel pipeline, blitting flags etc. No 100% guarantee that itself is correct, but in the end it will serve as a verification for software/hardware driver.

Hello,

the softdevice team (Torgeir Veimo, Martin Wache and me, Stefan Lucke)
is pleased to announce a new release of vdr's softdevice plugin.

General info:
Softdevice plugin enables vdr to run on your desktop with
so called budget cards. You'll get vdr output via framebuffer or X11-Xv or
DirectFB or vidix to your screen. Decoding is done via ffmpeg.

This is just a maintance release for previous 0.3.0 version, as code
for support of vdr version earlier than vdr-1.3.7 will be removed soon.

Supported vdr versions: (1.2.x,) 1.3.x and 1.4.x

Plugin's homepage is located at: Пожалуйста зарегистрируйся для просмотра данной ссылки на страницу.

Changelog since last release:
2006-11-05: softdevice-0.3.1
- xv-out: limit used width & height to screen dimensions.
- audio: select alsa h/w-mixer for volume control via command line.
2006-10-11:
- hopfull final color jump fix for odd "cut columns from left" values.
- fix horizontal picture placement when YUY2 is selected for xv-out.
2006-10-10:
- fix segfaults when YUY2 pixelformat is used for xv-out and cut lines
from top is non zero. This fixes wrong colors and misplaced OSD drawing
too, when cut colums from left is non zero.
