Description: Splash screen
|

The vlc needs a splash screen with a vlc logo, instead of
|
||||
the "waiting for stream" message.

Description: Better Gnome interface
|

The Gnome interface has many stubs and is actually rather
|

unfunctional. Someone should make the buttons work when
|

the appropriate hooks exist.

Description: Playlist API
|

Currently only files given in the command line are played,
|
||||
one after the other. We need a smarter way to handle this,
|
||||
through AddFile(), MoveFile(), etc. functions. input_file
|
||||
has to be modified to support this as well.

Description: Get rid of vlc.channels

The file vlc.channels should be removed and information

found in it put either into ~/.vlcrc or in another rc
|

Description: vlms backport
|

The vlc uses the same file input code as the vlms (VideoLAN
|

Mini Server) which has been much improved. Someone should
|

port modifications done to the vlms back to the vlc.

Description: Optimize video parser
|
||||
The video parser has some speed issues currently unexplained:
|
||||
even though most functions are inlined, it keeps eating more
|
||||
CPU than it should. This has to be investigated.

Description: Fix VDEC_SMP segfaults
|

When compiled to support SMP, the vlc segfaults. The synchro
|

code lacks locks, but there might be bugs elsewhere as well.

Description: Get rid of floating instructions
|
||||
Mixing floating instructions and MMX is seldom a good idea,
|
||||
it might be interesting to remove all floating instructions
|
||||
in a single thread. The audio decoders are of course not
|
||||
concerned by this task.

Description: Get rid of dumb vlc aliases
|
||||
When compiling the vlc, some symlinks to the main app
|
||||
are created, such as gvlc, ggivlc, etc. Actually this
|
||||
might confuse the user, so they should be removed,
|
||||
except perhaps gvlc and fbvlc which follow a usual
|
||||
naming scheme.

|

Difficulty: Medium
|
||||
Urgency: Important
|
||||
Description: Do separate packages
|
||||
The plugins can be compiled with specific libraries, such
|
||||
as Gnome, GGI, Esound. Putting all of them in the same
|
||||
package would require a lot of useless dependencies, thus
|
||||
one should do separate packages: a core "vlc" package, and
|
||||
"vlc-fb", "vlc-ggi", "vlc-esd" packages depending on the
|
||||
core package.

Urgency: Important
|

Description: Allow to force synchro
|
||||
Add a --force-synchro option to bypass the auto-adaptative
|
||||
algorithm present in the vlc. Options should allow displaying
|
||||
only I frames, only I and P, or all frames, or some more
|
||||
fancy stuff such as half the Bs.

Difficulty: Hard

Urgency: Critical
|
||||
Description: Fix synchro
|
||||
The synchronization algorithm sucks a bit. While it is
|
||||
quite efficient on frameskipping on slow machines, it
|
||||
is not smart enough on fast machines and does not detect
|
||||
when it has enough time for a frame. Perhaps a better
|
||||
handling of the dates might help.

Description: Framebuffer exit bug
|
||||
When the vlc abnormally exits in framebuffer mode, it leaves
|
||||
the console in an unusable state. This does not happen on
|
||||
the Matrox framebuffer, but it does on the VESA one.

Description: Rename channel names

Description: Better black&white support
|

When in B&W mode, the chroma part of pictures is decoded,

the video decoder knows it does not need to.

Description: Split interface/video_output
|

The interface and the vout modules are too dependant, which
|

makes it impossible to run the Glide output with the Gnome

interface for instance. This will require a major rewrite of
|

the interface, and a solid knowledge of how the vlc internals
