13 Description: Fix backwards moves
14 Sometimes the frames seem to go backwards for a short period of
15 time. This is due to the output methods and is known to happen
16 with the x11 and SDL plugins.
22 Description: Have more statistics messages displayed
23 The vlc has structures to keep track of the interesting
24 events, but there is no way to print these structures. In stats
25 mode, we should print these structures regularly, or at quit
26 time (whichever is the more convenient).
32 Description: Separate optimizations from debug mode
33 We sometimes want to have the debug mode (which writes an
34 interesting log of debug messages) along with the compiler
35 optimizations (which allow decoding of more than 2 fps).
36 Status: Done 18 Nov 2000 (Meuuh)
41 Description: Write intf_WarnMsg and intf_StatMsg
42 We have intf_ErrMsg to display fatal errors, but warnings are
43 drowned in an ocean of unreadable intf_DbgMsg. Same for
50 Description: Support SDL Overlay
51 The SDL livrary has routines to use the video board to do the YUV
52 conversion, scaling and displaying. Using them will require a
53 partial rewrite of the video_output way of handling rendering
60 Description: Rewrite the font display routines
61 The current font display routines aren't powerful enough. There
62 should be a way to display a big String at once, without needing
63 to compute the size of the string and its coordinates beforehand.
69 Description: Make aout eat less CPU
70 When the vlc is launched without a stream, the audio_output thread
71 eats all memory, probably because there is no msleep() when no data
72 is available in the audio_output queue.
78 Description: Fix motion compensation bug
79 The motion compensation still has a small bug which can be well
80 noticed when there is a sudden color change, a few blocks remain
81 visible on the screen.
82 Status: Done 27 Aug 2000 (Meuuh)
88 . Finish the new keyboard input interface to support
89 interfaces that allow modifiers. This will allow the SDL to run
91 . Here are some details:
92 Allow any interface to have its own set of keys:
93 - allow the 'discovery' of the main interface of the binding
94 created by each interface:
95 what key ("control-C", what action (INTF...))
96 - extend the interface by a specific struct (meta+modifier+ascii)
97 - implement an interface specific getKey function.
103 Description: Fix plugins namespace problem
104 When compiling a plugin, all symbols seem to be exported, while we
105 actually just need GetConfig and a few other things: the other
106 functions are accessed through function pointers.
112 Description: Fix plugin autoloading
113 At the moment, plugins to be detected are hardcoded in the code. We
114 need a better method to get all available plugins, by listing all the
115 files in selected directories.
121 Description: Real plugin API
122 We need some functions to register plugins, automatically detect which
123 ones are the most appropriate, as well as ways to express that plugin
124 A won't work unless plugin B is activated as well.
130 Description: Enable compiled-in plugins
131 Some plugins may have their place inside the main program, such as the
132 dummy plugin, or the beos plugin under BeOS. We should allow to link
133 them with the main app.
139 Description: Optimize SPU rendering
140 There is an if() in the SPU display routine to double lines when needed,
141 whiwh is rather inefficient. It should be removed and put outside
143 Status: Done 26 Aug 2000 (henri)
148 Description: SPU error recovery
149 The SPU decoder does not behave very well when a packet is missed or when
150 it gets the stream at the middle of an SPU packet. Make it more error-
157 Description: ALSA audio output support
158 ALSA is the Advanced Linux Sound Architecture and is believed to be
159 technically superior to the usual OSS support found in the Linux kernel.
160 Status: Done ( henri )
165 Description: Support for RTP
166 RTP is a transport protocol for realtime applications. MPEG1 and MPEG2
167 versions of RTP are described in RFCs 2038 and 2250. RFCs 1889 (RTP)
168 and 2508 (compressed RTP) can be interesting as well.
174 Description: Draw a font / support color fonts
175 The vlc currently uses an ugly font to display its data on the output
176 window, and we have a slow hack to make it outlined. Writing our own
177 font, or adding support for color fonts, would make us gain some time.
183 Description: Layer 2 mono support
184 The vlc doesn't play layer 2 mono yet. We need it since a few of our
185 streams are in this audio format.
191 Description: MP3 support
192 The vlc cannot play MPEG1/2 layer 3 yet. It might be nice to fix that.
198 Description: Support for unencapsulated streams
199 Some streams are not encapsulated in PES/PS or TS packets, which the
200 vlc currently requires to properly decode a stream. Adding support for
201 this would require to rewrite the input code, and probably make it a
208 Description: Ogg/Vorbis audio decoder support
209 The Ogg/Vorbis audio format is a free alternative to the patent-encumbered
210 MP3 format. The system packets are quite different than the MPEG ones, so
211 adding support for it would require a lot of code rewrite.
217 Description: Xv video output support
218 XFree 4.0 provides the Xv interface which can do hardware YUV on supported
219 hardware. Unfortunately, there doesn't seem to be much documentation
226 Description: SDL video output support
227 The Simple DirectMedia Layer library is a generic API that provides
228 YUV acceleration on some platforms. More information can be found
229 on http://www.devolution.com/~slouken/SDL/
230 Status: Done 21 Aug 2000 (octplane)
235 Description: Implement pause
236 There is no real `pause' command yet. Pausing just stops
237 displaying and sound playback, but the streams continues to
238 be decoded. One will have to do a file implementation as
239 well as a network implementation.
245 Description: Rewrite input for Program Stream files
246 Currently when we read a PS file, it is first translated to TS
247 because we first had only PS support. Now time has come to get
248 rid of this ugly kludge and integrate a proper PS input.
254 Description: DeCSS and DVD ioctls
255 The vlc needs the DVD ioctls support as well as the integration
256 of DeCSS to play DVDs properly. The person doing this should
257 probably not live in a country where DeCSS has been ruled illegal.
263 Description: ASCII-art output
264 For the ones who don't know how to waste their time, they can
265 try to do an ASCII-art output plugin.
271 Description: LPCM decoder
272 The LPCM decoder is full of stubs, it only parses the stream
273 but does not decode it. Fix this.
279 Description: Fix field pictures support
280 Some MPEG2 streams are interleaved, and the vlc does not support
281 this very well. Adding support for them requires an excellent
282 knowledge of the MPEG2 papers.
283 Status: Done 23 Aug 2000 (Meuuh)
288 Description: Modularize decoder
289 Make the decoder a plugin, so that two versions can coexist
290 without recompilation (MMX and non-MMX).
296 Description: Make interface more responsive
298 When in "waiting for stream" mode, the interface is refreshed
299 every 5 seconds. This is too long, and can be confusing for
300 the user. Make it refresh at least after a keyboard/mouse event.
306 Description: Support MP1 and MP3
307 The vlc does not support all MPEG1 audio formats yet, nor
308 does it support MPEG1/2 layer 3.
313 Description: Split interface/video_output
314 The interface and the vout modules are too dependant, which
315 makes it impossible to run the Glide output with the Gnome
316 interface for instance. This will require a major rewrite of
317 the interface, and a solid knowledge of how the vlc internals
324 Description: Add 24bpp YUV
325 There is no 24bpp support yet. Add it, either in MMX
332 Description: Fix 8bpp YUV
333 The 8bpp YUV function is broken, there is some serious
334 alpha blending, and it scales pretty badly. Fix it.
335 Status: Done 14 Aug 2000 (sam)
340 Description: Fix input_file exit
341 input_file does not exit cleanly when the file is finished,
342 which makes it impossible to quit the vlc. Fix it.
343 Status: Done 21 Aug 2000 (sam)
348 Description: Debug MPEG1 video
349 The MPEG1 support has been done, but it still crashes.
350 Status: Done 23 Oct 2000 (Meuuh)
355 Description: Support MPEG1 timecodes
356 The vlc can parse an MPEG1 system stream, but the parsed
357 PCR values do not seem to be correct. Check what's wrong.
363 Description: Fix 32bpp MMX YUV
364 The MMX 32bpp YUV function is buggy.
365 Status: Done 13 Aug 2000 (sam)
370 Description: Optimize YUV scaling
371 The YUV scaling method does not seem very efficient. Perhaps
372 some CPU cycles can be gained by saving some buffers.
378 Description: Draw a vlc icon
379 The vlc needs an icon. It should render well in 48x48 but
386 Description: Better black&white support
387 When in B&W mode, the chroma part of pictures is decoded,
388 but it would be more efficient not to decode at all when
389 the video decoder knows it does not need to.
395 Description: Rename channel names
396 Channels should start from 1 (not 0) like on a VCR or TV,
397 and Channel 0 should be renamed to "Playlist" or similar.
403 Description: Framebuffer exit bug
404 When the vlc abnormally exits in framebuffer mode, it leaves
405 the console in an unusable state. This does not happen on
406 the Matrox framebuffer, but it does on the VESA one.
412 Description: Fix synchro
413 The synchronization algorithm sucks a bit. While it is
414 quite efficient on frameskipping on slow machines, it
415 is not smart enough on fast machines and does not detect
416 when it has enough time for a frame. Perhaps a better
417 handling of the dates might help.
418 Status: Done 13 Nov 2000 (Meuuh)
423 Description: Allow to force synchro
424 Add a --force-synchro option to bypass the auto-adaptative
425 algorithm present in the vlc. Options should allow displaying
426 only I frames, only I and P, or all frames, or some more
427 fancy stuff such as half the Bs.
428 Status: Done 8 Aug 2000 (sam)
433 Description: Do separate packages
434 The plugins can be compiled with specific libraries, such
435 as Gnome, GGI, Esound. Putting all of them in the same
436 package would require a lot of useless dependencies, thus
437 one should do separate packages: a core "vlc" package, and
438 "vlc-fb", "vlc-ggi", "vlc-esd" packages depending on the
440 Status: Done 15 Aug 2000 (sam)
445 Description: Get rid of dumb vlc aliases
446 When compiling the vlc, some symlinks to the main app
447 are created, such as gvlc, ggivlc, etc. Actually this
448 might confuse the user, so they should be removed,
449 except perhaps gvlc and fbvlc which follow a usual
451 Status: Done 8 Aug 2000 (sam)
456 Description: Get rid of floating instructions
457 Mixing floating instructions and MMX is seldom a good idea,
458 it might be interesting to remove all floating instructions
459 in a single thread. The audio decoders are of course not
460 concerned by this task.
466 Description: Fix VDEC_SMP segfaults
467 When compiled to support SMP, the vlc segfaults. The synchro
468 code lacks locks, but there might be bugs elsewhere as well.
469 Status: Done 16 Nov 2000 (Meuuh)
474 Description: Optimize video parser
475 The video parser has some speed issues currently unexplained:
476 even though most functions are inlined, it keeps eating more
477 CPU than it should. This has to be investigated.
483 Description: Backport vlms input
484 The vlc uses the same file input code as the vlms (VideoLAN
485 Mini Server) which has been much improved. Someone should
486 port modifications done to the vlms back to the vlc.
492 Description: Get rid of vlc.channels
493 The file vlc.channels should be removed and information
494 found in it put either into ~/.vlcrc or in another rc
495 file. Note that this file can be modified by the vlc.
501 Description: Playlist API
502 Currently only files given in the command line are played,
503 one after the other. We need a smarter way to handle this,
504 through AddFile(), MoveFile(), etc. functions. input_file
505 has to be modified to support this as well.
511 Description: Better Gnome interface
512 The Gnome interface has many stubs and is actually rather
513 unfunctional. Someone should make the buttons work when
514 the appropriate hooks exist.
521 The Matrox acceleration for the vlc does not work yet,
522 though there are initialization routines in the code.
528 Description: Splash screen
529 The vlc needs a splash screen with a vlc logo, instead of
530 the "waiting for stream" message.
