13 Description: Write stream zones support
14 For random access we need to know where stream descriptors are valid
15 and reside (essentially DVD plugin). -> Meuuh
21 Description: Write subtitles and stream information in YUV coordinates
22 ... so that they can be displayed even in "overlay" mode.
28 Description: Update documentation
29 The input structures have undergone a major restructuration with
30 input-II. It might be a good idea to reflect thoses changes in the
37 Description: Write AVI input plugin
38 .avi files can use MPEG codec, if this is the case it shouldn't be
39 hard to read those files -> Meuuh
45 Description: Write ES input plugin
46 We need to be able to read .mpg video streams, or .mp* audio streams.
47 More information -> Meuuh
53 Description: Write a new buffer allocator
54 Avoid malloc()s by reusing the recently released packets. More
61 Description: Fix audio synchro
62 With some audio plugins, the audio stream is late because of buffer
63 sizes. See what's wrong and fix it.
69 Description: Make decoders dynamically loadable
75 Description: Make input plugins dynamically loadable
76 With a probe() function, and stuff...
82 Description: Write DVD plugin
83 We need a DVD plugin which read the device directly, calls DeCSS
84 (optional) and parse .ifo files.
90 Description: Write input_ext-intf.c
91 This file will provide functions which allow the interface to change
92 the pace of reading and change the position in the file.
98 Description: Write TS support
99 The parser has already been back-ported, but it still lacks the
100 PSI parser, and currently the functions to read from the network
101 are yet to be written.
107 Description: Write input_netlist.c
108 We need an interface to create fixed-size packets (for instance
109 188 bytes or 2 kB) and avoid using the system malloc().
110 Status: Done 23 Jan 2001 (henri)
115 Description: Write input_programs.c
116 We need a centralized manner of creating new programs, es, and
117 spawning new decoders.
118 Status: Done 20 Dec 2000 (Meuuh)
123 Description: Fix the PS plugin
124 The PS plugin should be able to recover from packet loss, to
125 read MPEG-1 .mpg files, and to pre-parse the stream (if possible)
126 to build the ES table. Check what's wrong and fix it. Now.
127 Status: Done 20 Dec 2000 (Meuuh)
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...
137 Status: Done 20 Dec 2000 (sam)
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.
146 Status: Done 27 Nov 2000 (Meuuh)
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).
156 Status: Done 27 Nov 2000 (Meuuh)
161 Description: Separate optimizations from debug mode
162 We sometimes want to have the debug mode (which writes an
163 interesting log of debug messages) along with the compiler
164 optimizations (which allow decoding of more than 2 fps).
165 Status: Done 18 Nov 2000 (Meuuh)
170 Description: Write intf_WarnMsg and intf_StatMsg
171 We have intf_ErrMsg to display fatal errors, but warnings are
172 drowned in an ocean of unreadable intf_DbgMsg. Same for
174 Status: Done 23 Nov 2000 (Stef)
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
189 Description: Rewrite the font display routines
190 The current font display routines aren't powerful enough. There
191 should be a way to display a big String at once, without needing
192 to compute the size of the string and its coordinates beforehand.
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.
207 Description: Fix motion compensation bug
208 The motion compensation still has a small bug which can be well
209 noticed when there is a sudden color change, a few blocks remain
210 visible on the screen.
211 Status: Done 27 Aug 2000 (Meuuh)
217 . Finish the new keyboard input interface to support
218 interfaces that allow modifiers. This will allow the SDL to run
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.
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.
241 Description: Fix plugin autoloading
242 At the moment, plugins to be detected are hardcoded in the code. We
243 need a better method to get all available plugins, by listing all the
244 files in selected directories.
250 Description: Real plugin API
251 We need some functions to register plugins, automatically detect which
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.
259 Description: Enable compiled-in plugins
260 Some plugins may have their place inside the main program, such as the
261 dummy plugin, or the beos plugin under BeOS. We should allow to link
262 them with the main app.
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
272 Status: Done 26 Aug 2000 (henri)
277 Description: SPU error recovery
278 The SPU decoder does not behave very well when a packet is missed or when
279 it gets the stream at the middle of an SPU packet. Make it more error-
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.
295 Description: Buy a new brain for Sam
296 Sam likes to show that he is a good developer, and for a good developer
297 hexadecimal notation really rules, though nobody really needs it. In this
298 TODO list, Sam has forgotten that 0x29 + 1 != 0x30, but 0x2a ! So, please
299 do something, and send your donations to sam@via.ecp.fr. Thanks for him.
305 Description: ALSA audio output support
306 ALSA is the Advanced Linux Sound Architecture and is believed to be
307 technically superior to the usual OSS support found in the Linux kernel.
308 Status: Done ( henri )
313 Description: Support for RTP
314 RTP is a transport protocol for realtime applications. MPEG1 and MPEG2
315 versions of RTP are described in RFCs 2038 and 2250. RFCs 1889 (RTP)
316 and 2508 (compressed RTP) can be interesting as well.
322 Description: Draw a font / support color fonts
323 The vlc currently uses an ugly font to display its data on the output
324 window, and we have a slow hack to make it outlined. Writing our own
325 font, or adding support for color fonts, would make us gain some time.
331 Description: Layer 2 mono support
332 The vlc doesn't play layer 2 mono yet. We need it since a few of our
333 streams are in this audio format.
339 Description: MP3 support
340 The vlc cannot play MPEG1/2 layer 3 yet. It might be nice to fix that.
346 Description: Support for unencapsulated streams
347 Some streams are not encapsulated in PES/PS or TS packets, which the
348 vlc currently requires to properly decode a stream. Adding support for
349 this would require to rewrite the input code, and probably make it a
356 Description: Ogg/Vorbis audio decoder support
357 The Ogg/Vorbis audio format is a free alternative to the patent-encumbered
358 MP3 format. The system packets are quite different than the MPEG ones, so
359 adding support for it would require a lot of code rewrite.
365 Description: Xv video output support
366 XFree 4.0 provides the Xv interface which can do hardware YUV on supported
367 hardware. Unfortunately, there doesn't seem to be much documentation
374 Description: SDL video output support
375 The Simple DirectMedia Layer library is a generic API that provides
376 YUV acceleration on some platforms. More information can be found
377 on http://www.devolution.com/~slouken/SDL/
378 Status: Done 21 Aug 2000 (octplane)
383 Description: Implement pause
384 There is no real `pause' command yet. Pausing just stops
385 displaying and sound playback, but the streams continues to
386 be decoded. One will have to do a file implementation as
387 well as a network implementation.
393 Description: Rewrite input for Program Stream files
394 Currently when we read a PS file, it is first translated to TS
395 because we first had only PS support. Now time has come to get
396 rid of this ugly kludge and integrate a proper PS input.
402 Description: DeCSS and DVD ioctls
403 The vlc needs the DVD ioctls support as well as the integration
404 of DeCSS to play DVDs properly. The person doing this should
405 probably not live in a country where DeCSS has been ruled illegal.
411 Description: ASCII-art output
412 For the ones who don't know how to waste their time, they can
413 try to do an ASCII-art output plugin.
419 Description: LPCM decoder
420 The LPCM decoder is full of stubs, it only parses the stream
421 but does not decode it. Fix this.
427 Description: Fix field pictures support
428 Some MPEG2 streams are interleaved, and the vlc does not support
429 this very well. Adding support for them requires an excellent
430 knowledge of the MPEG2 papers.
431 Status: Done 23 Aug 2000 (Meuuh)
436 Description: Modularize decoder
437 Make the decoder a plugin, so that two versions can coexist
438 without recompilation (MMX and non-MMX).
444 Description: Make interface more responsive
446 When in "waiting for stream" mode, the interface is refreshed
447 every 5 seconds. This is too long, and can be confusing for
448 the user. Make it refresh at least after a keyboard/mouse event.
454 Description: Support MP1 and MP3
455 The vlc does not support all MPEG1 audio formats yet, nor
456 does it support MPEG1/2 layer 3.
461 Description: Split interface/video_output
462 The interface and the vout modules are too dependant, which
463 makes it impossible to run the Glide output with the Gnome
464 interface for instance. This will require a major rewrite of
465 the interface, and a solid knowledge of how the vlc internals
472 Description: Add 24bpp YUV
473 There is no 24bpp support yet. Add it, either in MMX
480 Description: Fix 8bpp YUV
481 The 8bpp YUV function is broken, there is some serious
482 alpha blending, and it scales pretty badly. Fix it.
483 Status: Done 14 Aug 2000 (sam)
488 Description: Fix input_file exit
489 input_file does not exit cleanly when the file is finished,
490 which makes it impossible to quit the vlc. Fix it.
491 Status: Done 21 Aug 2000 (sam)
496 Description: Debug MPEG1 video
497 The MPEG1 support has been done, but it still crashes.
498 Status: Done 23 Oct 2000 (Meuuh)
503 Description: Support MPEG1 timecodes
504 The vlc can parse an MPEG1 system stream, but the parsed
505 PCR values do not seem to be correct. Check what's wrong.
511 Description: Fix 32bpp MMX YUV
512 The MMX 32bpp YUV function is buggy.
513 Status: Done 13 Aug 2000 (sam)
518 Description: Optimize YUV scaling
519 The YUV scaling method does not seem very efficient. Perhaps
520 some CPU cycles can be gained by saving some buffers.
526 Description: Draw a vlc icon
527 The vlc needs an icon. It should render well in 48x48 but
534 Description: Better black&white support
535 When in B&W mode, the chroma part of pictures is decoded,
536 but it would be more efficient not to decode at all when
537 the video decoder knows it does not need to.
543 Description: Rename channel names
544 Channels should start from 1 (not 0) like on a VCR or TV,
545 and Channel 0 should be renamed to "Playlist" or similar.
551 Description: Framebuffer exit bug
552 When the vlc abnormally exits in framebuffer mode, it leaves
553 the console in an unusable state. This does not happen on
554 the Matrox framebuffer, but it does on the VESA one.
560 Description: Fix synchro
561 The synchronization algorithm sucks a bit. While it is
562 quite efficient on frameskipping on slow machines, it
563 is not smart enough on fast machines and does not detect
564 when it has enough time for a frame. Perhaps a better
565 handling of the dates might help.
566 Status: Done 13 Nov 2000 (Meuuh)
571 Description: Allow to force synchro
572 Add a --force-synchro option to bypass the auto-adaptative
573 algorithm present in the vlc. Options should allow displaying
574 only I frames, only I and P, or all frames, or some more
575 fancy stuff such as half the Bs.
576 Status: Done 8 Aug 2000 (sam)
581 Description: Do separate packages
582 The plugins can be compiled with specific libraries, such
583 as Gnome, GGI, Esound. Putting all of them in the same
584 package would require a lot of useless dependencies, thus
585 one should do separate packages: a core "vlc" package, and
586 "vlc-fb", "vlc-ggi", "vlc-esd" packages depending on the
588 Status: Done 15 Aug 2000 (sam)
593 Description: Get rid of dumb vlc aliases
594 When compiling the vlc, some symlinks to the main app
595 are created, such as gvlc, ggivlc, etc. Actually this
596 might confuse the user, so they should be removed,
597 except perhaps gvlc and fbvlc which follow a usual
599 Status: Done 8 Aug 2000 (sam)
604 Description: Get rid of floating instructions
605 Mixing floating instructions and MMX is seldom a good idea,
606 it might be interesting to remove all floating instructions
607 in a single thread. The audio decoders are of course not
608 concerned by this task.
614 Description: Fix VDEC_SMP segfaults
615 When compiled to support SMP, the vlc segfaults. The synchro
616 code lacks locks, but there might be bugs elsewhere as well.
617 Status: Done 16 Nov 2000 (Meuuh)
622 Description: Optimize video parser
623 The video parser has some speed issues currently unexplained:
624 even though most functions are inlined, it keeps eating more
625 CPU than it should. This has to be investigated.
631 Description: Backport vlms input
632 The vlc uses the same file input code as the vlms (VideoLAN
633 Mini Server) which has been much improved. Someone should
634 port modifications done to the vlms back to the vlc.
640 Description: Get rid of vlc.channels
641 The file vlc.channels should be removed and information
642 found in it put either into ~/.vlcrc or in another rc
643 file. Note that this file can be modified by the vlc.
649 Description: Playlist API
650 Currently only files given in the command line are played,
651 one after the other. We need a smarter way to handle this,
652 through AddFile(), MoveFile(), etc. functions. input_file
653 has to be modified to support this as well.
659 Description: Better Gnome interface
660 The Gnome interface has many stubs and is actually rather
661 unfunctional. Someone should make the buttons work when
662 the appropriate hooks exist.
669 The Matrox acceleration for the vlc does not work yet,
670 though there are initialization routines in the code.
676 Description: Splash screen
677 The vlc needs a splash screen with a vlc logo, instead of
678 the "waiting for stream" message.
