# # vlc tasks # --------- # # # Difficulty values: Easy, Medium, Hard, Guru # # Urgency values: Wishlist, Normal, Important, Critical Task: 0x39 Difficulty: Medium Urgency: Wishlist Description: Rewrite the font display routines The current font display routines aren't powerful enough. There should be a way to display a big String at once, without needing to compute the size of the string and its coordinates beforehand. Status: Todo Task: 0x38 Difficulty: Medium Urgency: Important Description: Make aout eat less CPU When the vlc is launched without a stream, the audio_output thread eats all memory, probably because there is no msleep() when no data is available in the audio_output queue. Status: Todo Task: 0x37 Difficulty: Guru Urgency: Important Description: Fix motion compensation bug The motion compensation still has a small bug which can be well noticed when there is a sudden color change, a few blocks remain visible on the screen. Status: Done 27 Aug 2000 (Meuuh) Task: 0x36 Difficulty: Medium Urgency: Normal Description: . Finish the new keyboard input interface to support interfaces that allow modifiers. This will allow the SDL to run properly. . Here are some details: Allow any interface to have its own set of keys: - allow the 'discovery' of the main interface of the binding created by each interface: what key ("control-C", what action (INTF...)) - extend the interface by a specific struct (meta+modifier+ascii) - implement an interface specific getKey function. Status: Todo Task: 0x35 Difficulty: Medium Urgency: Important Description: Fix plugins namespace problem When compiling a plugin, all symbols seem to be exported, while we actually just need GetConfig and a few other things: the other functions are accessed through function pointers. Status: Todo Task: 0x34 Difficulty: Medium Urgency: Important Description: Fix plugin autoloading At the moment, plugins to be detected are hardcoded in the code. We need a better method to get all available plugins, by listing all the files in selected directories. Status: Todo Task: 0x33 Difficulty: Hard Urgency: Important Description: Real plugin API We need some functions to register plugins, automatically detect which ones are the most appropriate, as well as ways to express that plugin A won't work unless plugin B is activated as well. Status: Todo Task: 0x32 Difficulty: Medium Urgency: Important Description: Enable compiled-in plugins Some plugins may have their place inside the main program, such as the dummy plugin, or the beos plugin under BeOS. We should allow to link them with the main app. Status: Todo Task: 0x31 Difficulty: Easy Urgency: Normal Description: Optimize SPU rendering There is an if() in the SPU display routine to double lines when needed, whiwh is rather inefficient. It should be removed and put outside the main loop. Status: Done 26 Aug 2000 (henri) Task: 0x30 Difficulty: Hard Urgency: Important Description: SPU error recovery The SPU decoder does not behave very well when a packet is missed or when it gets the stream at the middle of an SPU packet. Make it more error- friendly. Status: Todo Task: 0x29 Difficulty: Medium Urgency: Normal Description: ALSA audio output support ALSA is the Advanced Linux Sound Architecture and is believed to be technically superior to the usual OSS support found in the Linux kernel. Status: Todo Task: 0x28 Difficulty: Guru Urgency: Wishlist Description: Support for RTP RTP is a transport protocol for realtime applications. MPEG1 and MPEG2 versions of RTP are described in RFCs 2038 and 2250. RFCs 1889 (RTP) and 2508 (compressed RTP) can be interesting as well. Status: Todo Task: 0x27 Difficulty: Medium Urgency: Wishlist Description: Draw a font / support color fonts The vlc currently uses an ugly font to display its data on the output window, and we have a slow hack to make it outlined. Writing our own font, or adding support for color fonts, would make us gain some time. Status: Todo Task: 0x26 Difficulty: Medium Urgency: Important Description: Layer 2 mono support The vlc doesn't play layer 2 mono yet. We need it since a few of our streams are in this audio format. Status: Todo Task: 0x25 Difficulty: Hard Urgency: Wishlist Description: MP3 support The vlc cannot play MPEG1/2 layer 3 yet. It might be nice to fix that. Status: Todo Task: 0x24 Difficulty: Hard Urgency: Normal Description: Support for unencapsulated streams Some streams are not encapsulated in PES/PS or TS packets, which the vlc currently requires to properly decode a stream. Adding support for this would require to rewrite the input code, and probably make it a plugin. Status: Todo Task: 0x24 Difficulty: Guru Urgency: Wishlist Description: Ogg/Vorbis audio decoder support The Ogg/Vorbis audio format is a free alternative to the patent-encumbered MP3 format. The system packets are quite different than the MPEG ones, so adding support for it would require a lot of code rewrite. Status: Todo Task: 0x23 Difficulty: Guru Urgency: Normal Description: Xv video output support XFree 4.0 provides the Xv interface which can do hardware YUV on supported hardware. Unfortunately, there doesn't seem to be much documentation available. Status: Todo Task: 0x22 Difficulty: Medium Urgency: Normal Description: SDL video output support The Simple DirectMedia Layer library is a generic API that provides YUV acceleration on some platforms. More information can be found on http://www.devolution.com/~slouken/SDL/ Status: Done 21 Aug 2000 (octplane) 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. 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: 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: 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: 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: 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: Done 23 Aug 2000 (Meuuh) 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: 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: 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: 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: 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: 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: Done 14 Aug 2000 (sam) 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: Done 21 Aug 2000 (sam) Task: 0x14 Difficulty: Guru Urgency: Wishlist Description: Debug MPEG1 video The MPEG1 support has been done, but it still crashes. 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: 0x12 Difficulty: Medium Urgency: Important Description: Fix 32bpp MMX YUV The MMX 32bpp YUV function is buggy. Status: Done 13 Aug 2000 (sam) 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: 0x10 Difficulty: Easy Urgency: Normal Description: Draw a vlc icon The vlc needs an icon. It should render well in 48x48 but can be any size. 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: 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: 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: 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: 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: 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: Done 15 Aug 2000 (sam) 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: 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: 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: 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: 0x05 Difficulty: Easy Urgency: Important Description: Backport vlms input 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: 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: 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: 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: 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: 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
