Check vlc_object_alive( p_demux ) && !p_demux->b_error in while loop.

Add an XDM 1.0 video encoder to modules/codec/davinci.c. This code
is simply copied from XDM 0.9 video_encoder.c and needs to be further
adapted for use with an XDM 1.0 video encoder.

Remove unused argument to function davinci_CopyPictureToXDM().

Optimize division by 2 with a right shift by 1.

Mark in modules/codec/davinci.c the CBR option as being available from XDM 1.0 onwards.

Solve compiler warnings:
- unused parameters
- unsigned vs signed comparisons

Replace the combination of malloc() and memset() on the same pointer by
one instance of calloc(), which does both.

Forgot to call davinci_RuntimeExit() wrapper on Close() for modules/codec/davinci/audio.c
in commit 4aef7755

Remove comments.

On each picture the video decoder wrapper did query XDM_GETSTATUS for decoder status,
but error information is alread available in p_sys->out_args in member 'extendedError'.
This patch saves one syscall every picture (except the first). The first picture defines
the output properties of the decoded pictures and these must be stored in p_dec->fmt_out.video.*
to obtain correctly sized pictures (picture_t).

No functional changes, but just cleaning up.

Remove inefficient memset() on the entire output picture. Instead the
framebuffer is expected to clear the display properly on initialization
and cleanup. This patch requires commit id: 09976bb9.

The framebuffer video output cleared the display in multiple places and it only
worked properly for RGB displays. This patch removes several memset() on the entire
framebuffer.
Clearing of the framebuffer is done in p_vout->pf_init() and p_vout->pf_end() taking
the chroma of the video output into account. Only RGB2, RV15, RV16, RV24, RV32, UYVY,
YUNV and Y422 chromas are currently supported.

Update the DaVinci resizer implementation modules/codec/davinci to latest
state of Rafael Carre his work. This introduces one new file 'resizer_coefs.c'.

The file modules/codec/davinci/fb.c used a hack to bypass VLC video
output chain in order to improve playback speed. By doing so it was
able to eliminate a lot of memory copies from and to different buffer
types.

Improvements for readability:
- Renamed p_sys->e to p_sys_>engine
- Renamed p_sys->d to p_sys->handle

Commit-id: 91ebe760 makes sure that
CERuntime_Init() and CERuntimeExit() are called only once. This commit
uses the wrappers that ensure that for audio and video decoder.

Optimize for the case where fullscreen is not requested. In that case just
copy the lines into a black destination picture and let the TV do the scaling.
If your TV does not do scaling, then you will see the video in original format.

If the source and destination picture are not of the same chroma (YVUV), then
use the resizer to do chroma conversion and scale at the same time.

Write directly into the special DSP buffer and only copy the remainder to a temporarily buffer.

- encoder.c: separate XDM 0.9 and XDM 1.0 code into separate files
- fourcc.c : indicate which XDM API to use for this codec

- remove hackish code for direct framebuffer output

Specifying a revision for ffmpeg has no influence on the libswscale. This will be
the current head of libswscale which might conflict with ffmpeg's HEAD. The
suggested revision to use is 29968, which must be forced by removing libswscale and
checking out: svn co -r 29968 svn://svn.ffmpeg.org/mplayer/trunk/libswscale libswscale

Forcing the encoder to output an key frame at every --sout-davinci-keyint setting improves the generated stream random access feature. A client picks up the stream every keyint frames now. While previous it didn't.

Capture audio in a seperate thread. It ensures that --input-slave oss:// runs independent of the video capturing and resulting in higher throughput.

This is a workaround for the Neuros OSD 2 linux kernel 2.6.23. Since vlc does a poll before a read it is guaranteed that there is data, thus using O_NONBLOCK does not really add any advantage here.

This reverts commit 3e1c59ce.
