+Task: 0x00
+Difficulty: Medium
+Urgency: Wishlist
+Description: Splash screen
+ The vlc needs a splash screen with a vlc logo, instead of
+ the "waiting for stream" message.
+Status: Todo
+
+Task: 0x01
+Difficulty: Hard
+Urgency: Wishlist
+Description: MGA YUV
+ The Matrox acceleration for the vlc does not work yet,
+ though there are initialization routines in the code.
+Status: Todo
+
+Task: 0x02
+Difficulty: Medium
+Urgency: Normal
+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.
+Status: Todo
+
+Task: 0x03
+Difficulty: Hard
+Urgency: Important
+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.
+Status: Todo
+
+Task: 0x04
+Difficulty: Medium
+Urgency: Normal
+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
+ file. Note that this file can be modified by the vlc.
+Status: Todo
+
+Task: 0x05
+Difficulty: Easy
+Urgency: Important
+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.
+Status: Todo
+
+Task: 0x06
+Difficulty: Guru
+Urgency: Important
+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.
+Status: Todo
+
+Task: 0x07
+Difficulty: Hard
+Urgency: Critical
+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.
+Status: Todo
+
+Task: 0x08
+Difficulty: Easy
+Urgency: Important
+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.
+Status: Todo
+
+Task: 0x09
+Difficulty: Easy
+Urgency: Normal
+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.
+Status: Done 8 Aug 2000 (sam)
+
+Task: 0x0a
+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.
+Status: Todo
+
+Task: 0x0b
+Difficulty: Medium
+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.
+Status: Done 8 Aug 2000 (sam)
+
+Task: 0x0c
+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.
+Status: Todo
+
+Task: 0x0d
+Difficulty: Medium
+Urgency: Important
+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.
+Status: Todo
+
+Task: 0x0e
+Difficulty: Easy
+Urgency: Wishlist
+Description: Rename channel names
+ Channels should start from 1 (not 0) like on a VCR or TV,
+ and Channel 0 should be renamed to "Playlist" or similar.
+Status: Todo
+
+Task: 0x0f
+Difficulty: Easy
+Urgency: Normal
+Description: Better black&white support
+ When in B&W mode, the chroma part of pictures is decoded,
+ but it would be more efficient not to decode at all when
+ the video decoder knows it does not need to.
+Status: Todo
+
+Task: 0x10
+Difficulty: Easy
+Urgency: Normal
+Description: vlc icon
+ The vlc needs an icon. It should render well in 48x48 but
+ can be any size.
+Status: Todo
+
+Task: 0x11
+Difficulty: Hard
+Urgency: Normal
+Description: Optimize YUV scaling
+ The YUV scaling method does not seem very efficient. Perhaps
+ some CPU cycles can be gained by saving some buffers.
+Status: Todo
+
+Task: 0x12
+Difficulty: Medium
+Urgency: Important
+Description: Fix 32bpp MMX YUV
+ The MMX 32bpp YUV function is buggy.
+Status: Todo
+
+Task: 0x13
+Difficulty: Hard
+Urgency: Wishlist
+Description: Support MPEG1 timecodes
+ The vlc can parse an MPEG1 system stream, but the parsed
+ PCR values do not seem to be correct. Check what's wrong.
+Status: Todo
+
+Task: 0x14
+Difficulty: Guru
+Urgency: Wishlist
+Description: Debug MPEG1 video
+ The MPEG1 support has been done, but it still crashes.
+Status: Todo
+
+Task: 0x15
+Difficulty: Medium
+Urgency: Critical
+Description: Fix input_file exit
+ input_file does not exit cleanly when the file is finished,
+ which makes it impossible to quit the vlc. Fix it.
+Status: Todo
+
+Task: 0x16
+Difficulty: Medium
+Urgency: Important
+Description: Fix 8bpp YUV
+ The 8bpp YUV function is broken, there is some serious
+ alpha blending, and it scales pretty badly. Fix it.
+Status: Todo
+
+Task: 0x17
+Difficulty: Hard
+Urgency: Normal
+Description: Add 24bpp YUV
+ There is no 24bpp support yet. Add it, either in MMX
+ or in C.
+Status: Todo
+
+Task: 0x18
+Difficulty: Guru
+Urgency: Wishlist
+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
+ work.
+Status: Todo
+
+Task: 0x19
+Difficulty: Hard
+Urgency: Normal
+Description: Support MP1 and MP3
+ The vlc does not support all MPEG1 audio formats yet, nor
+ does it support MPEG1/2 layer 3.
+ 
+Task: 0x1a
+Difficulty: Easy
+Urgency: Normal
+Description: Make interface more responsive
+Status: Todo
+ When in "waiting for stream" mode, the interface is refreshed
+ every 5 seconds. This is too long, and can be confusing for
+ the user. Make it refresh at least after a keyboard/mouse event.
+Status: Todo
+
+Task: 0x1b
+Difficulty: Hard
+Urgency: Wishlist
+Description: modularize decoder
+ Make the decoder a plugin, so that two versions can coexist
+ without recompilation (MMX and non-MMX).
+Status: Todo
+
+Task: 0x1c
+Difficulty: Guru
+Urgency: Important
+Description: Fix field pictures support
+ Some MPEG2 streams are interleaved, and the vlc does not support
+ this very well. Adding support for them requires an excellent
+ knowledge of the MPEG2 papers.
+Status: Todo
+
+Task: 0x1d
+Difficulty: Hard
+Urgency: Normal
+Description: LPCM decoder
+ The LPCM decoder is full of stubs, it only parses the stream
+ but does not decode it. Fix this.
+Status: Todo
+
+Task: 0x1e
+Difficulty: Hard
+Urgency: Wishlist
+Description: ASCII-art output
+ For the ones who don't know how to waste their time, they can
+ try to do an ASCII-art output plugin.
+Status: Todo
+
+Task: 0x1f
+Difficulty: Hard
+Urgency: Normal
+Description: DeCSS and DVD ioctls
+ The vlc needs the DVD ioctls support as well as the integration
+ of DeCSS to play DVDs properly. The person doing this should
+ probably not live in a country where DeCSS has been ruled illegal.
+Status: Todo
+
+Task: 0x20
+Difficulty: Hard
+Urgency: Important
+Description: Rewrite input for Program Stream files
+ Currently when we read a PS file, it is first translated to TS
+ because we first had only PS support. Now time has come to get
+ rid of this ugly kludge and integrate a proper PS input.
+Status: Todo
+
+Task: 0x21
+Difficulty: Medium
+Urgency: Normal
+Description: Implement pause
+ There is no real `pause' command yet. Pausing just stops
+ displaying and sound playback, but the streams continues to
+ be decoded. One will have to do a file implementation as
+ well as a network implementation.
