-
-0.9.6
-[ ] go back in all help files and fill in whatever is missing
-[ ] quicktime PNG encoding: does it work?
-[ ] add missing to index.pd
-[ ] about.pd: link from help menu; add link to website, mention irc, etc.
-
-unsorted
-[ ] [doc_cc] [doc_ii] [doc_oo]'s $1 doesn't really accept symbol now.
-[ ] remove last outlet of [#] when it's irrelevant, and don't have a $2 in that case, and don't check type of r in that case.
-[ ] can't handle [args] that come out as grid literals and have to become setter messages.
-[ ] [pack] trigger_by (choose which inlets are hot)
-[ ] GF objects don't have default methods like bang and list, unlike pd itself.
-[ ] bug in line rendering causes one pixel to be off by one pixel at the end of many linesegments. ([#draw_polygon] with hpgl)
-[ ] put_at is lacking some checks for number-of-dims, causing segfault.
-[ ] strange problem with [#import] when input size doesn't match output size and object is recreated
-[ ] get rid of doc/stuff.txt and doc/install.html
-[ ] fix [nbx]<->[hsl] relationship in [#camera]
-[ ] #line_to_polygon is buggy
-[ ] #draw_polygon init_lines() not sufficiently called
-[ ] conversion from float to int is inconsistent: when to round and when to trunc?
-[ ] with pwc, 720x480 crashes
-[ ] WILL NOT go through all the new [gf/...] to "clean things up" now; will not make help files of them right now either.
-[ ] what to do with [#motion_detection] ?
-[ ] [#saturation] is a linear colorspace transform: therefore it could be accelerated just like [#hueshift] could.
-[ ] try [# C.sq-] on chroma
-
-0.9.7
-[ ] listflatten-help.pd : [display] bug
-[ ] GridFlow Index dans toutes les fenêtres
-[ ] <mescalinum> matju: anyway, in #-help.pd, object [doc/numop] is still error
-[ ] [#reinterval] takes no argument
-[ ] [#draw_rect] doesn't support op, etc... what do we do about attributes?
-[ ] [doc_m] boxes are too big
-[ ] [#make_arrow] (fix and help)
-[ ] [#interval_overlap]
-
-Later
-[ ] [#in libv4l] and/or [#in unicap] and/or [#in videojack]
-<matju> oof -> error: [#io.quicktime in gf_spirals_and_moire.avi]: unknown colorspace 'yuv' (supported: rgb, rgba, bgr, bgrn, yuv, yuva)
-[ ] doc attributes: [doc_a] [doc_aa] ?
-[ ] [doc_ii] links to [doc_cc]
-[ ] regularise Grid[a,b] vs Grid Dim[a,b] vs Dim[a,b] vs a grid of size (a,b) or (a b)... big mess
-[ ] distinguish messages vs atoms in this manual
-    e.g. [doc_aa] would contain something like [doc_m]
-		but wouldn't have [doc_m] as a subnode.
-[ ] [print], [gf.print] bugs
-[ ] [gf/canvas_loadbang]: is it buggy? (see [doc_h] double-bang problem)
-[ ] probably a problem with loadbang: when making a new helppatch, it's better to save it and reload immediately,
-    to prevent a lot of redraw bugs.
-[ ] support "get" in abstractions... automatically, through [args] ?
-[ ] bugs/bugfixes from roman, claude, federico, etc
-[ ] [fps]: translate into pd: "publish if fps>0.001" (to remove outliers)
-[ ] reimplement negative indices in [listelement] and [listsublist]
-[ ] fix SDL modifiers
-[ ] fix quoting in [display]
-[ ] [args] have to be connected to a [t a] in common with first inlet... (BUT: this has an impact on float vs list distinction)
-    (why not make this automatic, by making [args] contact whichever inlet is first?)
-[ ] [#to_pix] newimage=0 to save CPU time and/or bus time?
-[ ] what to do with GridFlow version numbering?
-[ ] use [args] everywhere it should be used: e.g. [#background_model] but also many more
-[ ] reintroduce set_mode(0)
-[ ] [#fold] is slowwww
-[ ] [route3] is like [route] but doesn't trim.
-[ ] #out x11 doesn't accept 0-sized grids
-[ ] #inner doesnt support seeds of size>1, and isn't vecop-compatible, and ...
-[ ] #inner could optimise permutation matrices?
-[ ] claude wants http://en.wikipedia.org/wiki/Graham_scan
-[ ] make [#draw_points] [#edit_polygon]
-[ ] distinguish between C++ types Grid* and GridFlow*
-[ ] add [#out png]
-[ ] Accumulation of Background Statistics
-[ ] compenser pour les ajustements progressifs ou soudains de luminosité
-[ ] regular dc1394 options
-[ ] irregular dc1394 options: white_shading, white_balance; trigger_mode? trigger, trigger_delay
-
-OpenCV
-[ ] cvOpticalFlow
-[ ] [cv.split]
-[ ] cvEstimateRigidTransform
-[ ] cvApproxPoly pour un seul poly à la fois
-[ ] cvMeanShift, cvCamShift (?)
-       cvCamShift s'utilise presque comme MeanShift, sauf que ça requiert un autre type non-grid.
-       Celui-ci peut être représenté comme une grid de 5 éléments pour faire plus facile
-       (contrairement à cvHistogram, qui contient une grid ND mais a besoin de quelques fields de plus que ça).
-[ ] cvCalcBackProject (?)
-[ ] cvCalcHist, cvCreateHist.
-[ ] SnakeImage (what is the concept of 'energy', squared luminosity?)
-        J'aurais supposé que oui, mais c'est juste trois mesures reliées à trois forces qui "shapent" la courbe:
-	espacement égal des points, réduction des angles, et correspondance avec l'image même (qui doit normalement
-	être un edge-detect d'une image plus vieille).
-[ ] on doit aussi commencer à rajouter des types non-grid. Le premier sera CvHistogram et est requis pour tous les objets dont le nom contient "Hist".
-
-Common Video Framework
-[ ] a common library for all video IO (cameras, files, web), which is the project of Thomas H and Johannes.
-[ ] a six-way converter for GEM/PDP/GridFlow. There are already converters between GEM and PDP and between GEM and GridFlow
-    but there is none between PDP and GridFlow and then some things could be easier to install and run in a cross-platform way.
-[ ] a way to make GEM/PDP/GF conversions *implicitly* instead of having objects for that.
-[ ] threads for video?
-[ ] GEM geos vs 3DP: how do they compare?
-[ ] is there anything else deserving to be unified between the video plugins?
-[ ] look at camorama
-[ ] Generic Image Library: http://opensource.adobe.com/gil/html/giltutorial.html

-malloc alignment = 4 mod 8 (en utilisant valgrind)
-
-ClaudiusMaximus matju: feature request:  [#store4], behaves like store but accepts grids 
-of floats as coordinates and interpolate using 4-point interpolation, eg, right inlet -> 
-(3 3 f # 0 0 0 1 1 1 2 4 8), left inlet -> (1 # 0.5) outputs (0.5 0.5 0.5) 
-(or whatever the interpolation would really be), left inlet (2 # 1.5 1.5) outputs (3)
-
-http://oprofile.sourceforge.net/about/
-also: qprofile, amd profiler, opreport -cl --demangle=smart
-
-[ ] OpenCL
-[ ] look at the endian stuff that is most probably wrong... if I can run anything on a G4 or G5.
-[ ] -ftree-vectorizer-verbose
-[ ] try removing or modifying -falign on PPC/OSX
-[ ] encoding of quicktime RGBA (PNG) does not work at all!
-[ ] make example on separable convkernels
-[ ] add concepts of hot inlet and conf inlet at the code level
-[ ] [display] should use clocks to update tk less often
-[ ] deprecation warnings
-[ ] Add a video latency patch (in examples)
-[ ] Numop: warn on misalignment
-[ ] remove GridInlet* ?
-[ ] configure chokes if GCC3 doesn't have the C++ plugin
-[ ] [#import~] [#export~]
-[ ] [#expr]
-[ ] [#line]? [#pipe]? [#delay]?
-[ ] rewrite [#rgb_to_rgba] [#rgba_to_rgb] in C++ if I'm not going to rework [#inner] soon enough.
-[ ] #: option swap
-[ ] consider including [mysql] [renamefile] [ls] [shell]
-[ ] re-enable int64,float64
-[ ] add #matrix_solve, #slice
-[ ] Copy-on-Write (COW)
-[ ] internal grid protocol redesigned
-[ ] look into -ftree-vectorize
-[ ] look at Tetra Piccolo capture cards, as well as ImpactVCB (Hauppauge)
-[ ] some proper equivalent of [rubysprintf]... see also: [gf.error]
-[ ] small leak remaining in x11? may have to do with non-use of XDestroyImage?
-[ ] is [@convolve] actually cross-convolution? that is, convolves with a mirror image of the convolution matrix.
-[ ] #import with zero size crashes?
-[ ] numop ** can freeze GF
-[ ] osx: [#store] crash instead of raising
-[ ] MMX computations may be done misaligned, which may be bad.
-[ ] when file not found, mpeg error messages are wrong, they say the filename is "".
-[ ] osx: error: shmget failed (cannot allocate memory) in X11, for regular pictures
-[ ] "unsupported codec" bogus errors.
-[ ] format/mpeg3.c,quicktime.c might cause lockup on exit
-[ ] some seeds aren't typechecked
-[ ] GRID_FINISH triggered while backstore ???
-[ ] what would be a way to make GF work well with Pd's idea of a list?
-[ ] write unit tests about required functionality
-[ ] write unit tests about error checking
-[ ] make system to ensure everything is working before a release.
-[ ] it's possible to crash by sending data in two inlets of a same object at once
-
-Installation
-[ ] cross-compile: http://www.libsdl.org/extras/win32/cross/ http://rooster.stanford.edu/~ben/linux/cross.php
-
-Documentation
-[ ] document how to report bugs, basic troubleshooting
-[ ] document our distribution of the archives
-[ ] ascii conventions: [foo] vs "foo", etc.
-[ ] document internals
-[ ] describe indexmap in doc
-[ ] architecture: class->type/shape->use->role
-[ ] benchmarks (especially: simple video i/o)
-[ ] mimic [pdp_help_input] [pdp_help_output]: they are convenient
-
-Architecture
-[ ] reentrancy of objects (to allow true recursion)
-[ ] inlet-attrs (attrs associated to inlets) (see "same as arg" in help)
-[ ] eliminate the Dim class, replacing by Grid itself (?).
-[ ] pull mode (functional-style)
-[ ] bidirectional messages (constraint/relational-style)
-[ ] send-reply messages (imperative-style)
-[ ] add reflection (#global:classes, #global:methods, ...)
-[ ] transmitting grids by diffs?
-[ ] dispatch on _#{i}_-named methods (any selector one inlet)
-[ ] generalize the backstore
-[ ] Outlet#buffer should harmonise with the lcm of its corresponding Inlet#factor's.
-[ ] lazy grids: Grid#operator T* makes sure all the grid is received
-	and Grid#range(int start, int n, T bogus) makes sure the
-	specified part of the grid is received.
-[ ] accounting: grids messages packets numbers bytes copybytes
-[ ] memory profiling
-[ ] add a "query" class for debugging other objects? (would be able to extract extra info from each object/class)
-[ ] add a GridFlow::LaterException or something (which tells to retry later with the same packet because another
-    grid reception is not completed yet.) 
-[ ] interpret nested lists as n-dimensional.
-[ ] MMX memcpy() ?
-[ ] MMX _runtime_ autodetection
-[ ] find a good profiler to use with GridFlow.
-

-Tom Schouten wrote: «added demo/rawvideo.pf and some support scripts in bin/pf-rawvideo.*
-this is an example on how to use external programs for raw video input.
-rationale: mplayer is a very nice piece of software supporting virtually any input format/codec.
-since i'm not planning to waste time on integrating more input codecs in pf, the best alternative is to have mplayer
-(actually mencoder) or ffmpeg as a subprocess. the same will be done for recording later.»
