A good practice is to invalidate the window and leave it to the OS to decide if a repaint is or not needed.

As a side effect, this fixes some alternative task switchers (alt-tab) on WinNT (like TaskSwitcher or ATTv) that displayed a black rectangle instead of the preview of the skin, because the skin engine was not doing things the usual way.

Events like WM_PAINT should be processed in the WinProc, because
some functions directly call the WinProc (e.g UpdateWindow())

Don't do anything if the image doesn't change. Otherwise, some unpleasant
flickering occurs when the image is animated.

All UI related operations in Qt4 must be done on the UI thread, as
QtGui is not thread-safe internally.

LibVLC applications can now select their video memory format when the
video output is created. In particular, this allows preservation of the
original pixel dimensions.

While untested, this should also enable planar YCbCr rendering. Until
this, vmem assumed that all planes had equal pitches, so that subsampled
planes would not really work.

This should fix #3359.

Make sure the specified SDK exists, add a verbose mode, allow to change the default SDK.

Seems like most likely cause to #4078 (reappeared near sametime as toURI was introduced).

This is untested. Doxygen does not seem to work anymore here:
no module lists, no function documentation, only source code.

With this, we can parse an SDP the same way if it comes from SAP
(as sdp://...) or from a file or the network.

Windows CE for example doesn't have this function

Having to type "mux mp2t" was lame

remove obsolete patch forgotten in [4b6e13d3]

RTSP doesn't toggle pause state, it sends unconditional PLAY/PAUSE
commands. Let the VLM handle it.

This option prevents windows from being displayed in the alt-tab list.
This should fix trac #4343 for Vista and Win7  (to be tested)

We don't want an universal build on osx

redraw happens on getch() return, on timeout (1 second), or on keypress
wether the key was handled or not.

input change is now checked in the main loop

It contains the x264 version info and options used for encoding
If we let it in extradata it will not be present in the final file

libavcodec does that already, and this makes it easier to compare x264
options used by VLC and FFmpeg.

Comparing FFmpeg and VLC with the exact same set of options might help
finding why mpeg (at least mpeg2/mpeg4/flv) encoding is 5 times slower
with vlc than with ffmpeg, supposedly for the same set of options.

avoids integer overflow with aspect ratio = BIG:BIG
