122 Urgency: Important
123 Description: Fix the PS plugin
124 The PS plugin should be able to recover from packet loss, to

131 Urgency: Critical
132 Description: Enhance intf_*Msg
133 The intf_*Msg functions could be more clever : add "mymodule
134 warning/error:" and \n automatically. The new input already
135 uses such a behaviour, so we must hurry. It might be necessary
136 to modify all messages in all modules...

140 Difficulty: Guru
141 Urgency: Critical
142 Description: Fix backwards moves
143 Sometimes the frames seem to go backwards for a short period of
144 time. This is due to the output methods and is known to happen
145 with the x11 and SDL plugins.

148 Task: 0x3d
149 Difficulty: Easy
150 Urgency: Normal
151 Description: Have more statistics messages displayed
152 The vlc has structures to keep track of the interesting
153 events, but there is no way to print these structures. In stats
154 mode, we should print these structures regularly, or at quit
155 time (whichever is the more convenient).

177 Difficulty: Hard
178 Urgency: Important
179 Description: Support SDL Overlay
180 The SDL livrary has routines to use the video board to do the YUV
181 conversion, scaling and displaying. Using them will require a
182 partial rewrite of the video_output way of handling rendering
183 and displaying.

189 Description: Rewrite the font display routines

196 Difficulty: Medium
197 Urgency: Important
198 Description: Make aout eat less CPU
199 When the vlc is launched without a stream, the audio_output thread
200 eats all memory, probably because there is no msleep() when no data
201 is available in the audio_output queue.

215 Urgency: Normal
216 Description: Enhance the interface
217 . Finish the new keyboard input interface to support
218 interfaces that allow modifiers. This will allow the SDL to run
219 properly.
220 . Here are some details:
221 Allow any interface to have its own set of keys:
222 - allow the 'discovery' of the main interface of the binding
223 created by each interface:
224 what key ("control-C", what action (INTF...))
225 - extend the interface by a specific struct (meta+modifier+ascii)
226 - implement an interface specific getKey function.

231 Urgency: Important
232 Description: Fix plugins namespace problem
233 When compiling a plugin, all symbols seem to be exported, while we
234 actually just need GetConfig and a few other things: the other
235 functions are accessed through function pointers.
236 Status: Done 10 Jan 2001 (sam)
238 Task: 0x34
239 Difficulty: Medium
240 Urgency: Important
241 Description: Fix plugin autoloading

249 Urgency: Important
250 Description: Real plugin API

252 ones are the most appropriate, as well as ways to express that plugin
253 A won't work unless plugin B is activated as well.

258 Urgency: Important
259 Description: Enable compiled-in plugins

261 dummy plugin, or the beos plugin under BeOS. We should allow to link
262 them with the main app.

266 Difficulty: Easy
267 Urgency: Normal
268 Description: Optimize SPU rendering
269 There is an if() in the SPU display routine to double lines when needed,
270 whiwh is rather inefficient. It should be removed and put outside
271 the main loop.

276 Urgency: Important
277 Description: SPU error recovery

286 Description: Shoot the TODO list on the web site
287 The TODO list on the web site hasn't been updated for months. We may
288 wonder then why the hell to we put a TODO list on the web site ? Maybe
289 we'd better shoot it in the head, that would make its suffering end.

302 Urgency: Wishlist
303 Description: Support for RTP
304 RTP is a transport protocol for realtime applications. MPEG1 and MPEG2
305 versions of RTP are described in RFCs 2038 and 2250. RFCs 1889 (RTP)
306 and 2508 (compressed RTP) can be interesting as well.

310 Difficulty: Medium
311 Urgency: Wishlist
312 Description: Draw a font / support color fonts
313 The vlc currently uses an ugly font to display its data on the output
314 window, and we have a slow hack to make it outlined. Writing our own
315 font, or adding support for color fonts, would make us gain some time.

318 Task: 0x27
319 Difficulty: Medium
320 Urgency: Important
321 Description: Layer 2 mono support
322 The vlc doesn't play layer 2 mono yet. We need it since a few of our
323 streams are in this audio format.

333 Task: 0x25
334 Difficulty: Hard
335 Urgency: Normal
336 Description: Support for unencapsulated streams
337 Some streams are not encapsulated in PES/PS or TS packets, which the
338 vlc currently requires to properly decode a stream. Adding support for
339 this would require to rewrite the input code, and probably make it a
340 plugin.
341 Status: Todo
343 Task: 0x24
344 Difficulty: Guru
345 Urgency: Wishlist
346 Description: Ogg/Vorbis audio decoder support
347 The Ogg/Vorbis audio format is a free alternative to the patent-encumbered
348 MP3 format. The system packets are quite different than the MPEG ones, so
349 adding support for it would require a lot of code rewrite.

372 Urgency: Normal
373 Description: Implement pause
374 There is no real `pause' command yet. Pausing just stops
375 displaying and sound playback, but the streams continues to
376 be decoded. One will have to do a file implementation as
377 well as a network implementation.

382 Urgency: Important
383 Description: Rewrite input for Program Stream files
384 Currently when we read a PS file, it is first translated to TS
385 because we first had only PS support. Now time has come to get
386 rid of this ugly kludge and integrate a proper PS input.

391 Urgency: Normal
392 Description: DeCSS and DVD ioctls
393 The vlc needs the DVD ioctls support as well as the integration

433 Urgency: Normal
434 Description: Make interface more responsive

449 Difficulty: Guru
450 Urgency: Wishlist
451 Description: Split interface/video_output
452 The interface and the vout modules are too dependant, which
453 makes it impossible to run the Glide output with the Gnome

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

572 The plugins can be compiled with specific libraries, such
