• 2D animations for Android, IOS, web

  - by David Phillips

  Working on Windows 7 platform, I'm interested in creating an app that could run on Android devices (phone or tablet), IOS devices (iPhone, iPad), and the web. First target would be Android. Do you remember those old Arthur Murray footstep diagrams to teach dancing? I want to do the same thing, but animate the steps, so the user can play them all, as well as step forward or backward thru them at their own pace. Perhaps one could generate an animated GIF and then play it on the platform. So there would seem to be two parts to this: 1) A good way to generate the animation images. I can, for example, see using SketchUp - something I know - for this. But is there something better it would be worth investing in? And, 2) How to play the result, including options for playback speed control, and even forward/backward stepping? Ideally a single, or easily adaptable player to the three different OS platforms.

• Basic framework for presentations using HTML5 + javascript

  - by Brian C

  Do you know a framework for making presentations using only HTML5 and javascript technologies? I'm not talking about "export" features of various presentation software (powerpoint or OOo presentation). Some requirements for the presentations made with this "framework": take advantage of the latest HTML5 features (audio, video, canvas?) same with CSS3 (font support, gradient, shadows, transitions and transformations) If there's no such thing, example of good presentations or pointers on the subject would be appreciated.

• How to create beautiful Screencasts for your web apps?

  - by Abs

  Hello all, I am trying to create a screen cast for my new web app. I have just come across a great example of a screencast and I am wondering what is used to do this: Click on the video to play on this page. I am impressed with the animation when the mouse is clicked and zooming into images from different angles. Is this done with Actionscript or is there software that will make my life easier to do this? Thanks all for any help

• How do I get a USB hard-disk adaper to work with a PCMCIA USB card?

  - by Carl

  I have a PCMCIA (Cardbus) 32bit USB 2.0 2-port card. If I plug my MP3 player in it works fine. I have a USB adapter for a hard disk drive. When I plug that into the PCMCIA USB slot the light on that hard disk flashed between red and green - it should stay green. "USB Mass Storage device" is added in the Device Manager, but no drive letter appears in My Computer. The installing device icon down by the clock never goes away. (Windows XP SP3.)

• mount samba share on a vmware instance

  - by Riduidel

  I've a windows machine in which a linux server is run by a "VMWare player". From the windows machine, I want some folders to be mounted on the Linux virtual server. All this is done in a maven build (which is quite irrevelant here, in fact). From what I understand, to make these windows folders available as mountable ones, I have to do the following operations Share the folders as Samba ones using net share, this I have done. Access my virtual server and check which folders are already mounted (which seems to be doable using a less /etc/fstab), this I'll do soon Mount my samba shares using smbmount All that seems to my by far too hackish code. Could the same be done using ... say ... JMX/SNMP or any other high-level technology ?

• X264 encoding using Opencv

  - by user573193

  I am working with a high resolution camera: 4008x2672. I a writing a simple program which grabs frame from the camera and sends the frame to a avi file. For working with such a high resolution, I found only x264 codec that could do the trick (Suggestions welcome). I am using opencv for most of the image handling stuff. As mentioned in this post http://doom10.org/index.php?topic=1019.0 , I modified the AVCodecContext members as per ffmpeg presets for libx264 (Had to do this to avoid broken ffmpeg defaults settings error). This is output I am getting when I try to run the program [libx264 @ 0x992d040]non-strictly-monotonic PTS 1294846981.526675 1 0 //Timestamp camera_no frame_no 1294846981.621101 1 1 1294846981.715521 1 2 1294846981.809939 1 3 1294846981.904360 1 4 1294846981.998782 1 5 1294846982.093203 1 6 Last message repeated 7 times [avi @ 0x992beb0]st:0 error, non monotone timestamps -614891469123651720 = -614891469123651720 OpenCV Error: Unspecified error (Error while writing video frame) in icv_av_write_frame_FFMPEG, file /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp, line 1034 terminate called after throwing an instance of 'cv::Exception' what(): /home/ajoshi/ext/OpenCV-2.2.0/modules/highgui/src/cap_ffmpeg.cpp:1034: error: (-2) Error while writing video frame in function icv_av_write_frame_FFMPEG Aborted Modifications to the AVCodecContext are: if(codec_id == CODEC_ID_H264) { //fprintf(stderr, "Trying to parse a preset file for libx264\n"); //Setting Values manually from medium preset c-me_method = 7; c-qcompress=0.6; c-qmin = 10; c-qmax = 51; c-max_qdiff = 4; c-i_quant_factor=0.71; c-max_b_frames=3; c-b_frame_strategy = 1; c-me_range = 16; c-me_subpel_quality=7; c-coder_type = 1; c-scenechange_threshold=40; c-partitions = X264_PART_I8X8 | X264_PART_I4X4 | X264_PART_P8X8 | X264_PART_B8X8; c-flags = CODEC_FLAG_LOOP_FILTER; c-flags2 = CODEC_FLAG2_BPYRAMID | CODEC_FLAG2_MIXED_REFS | CODEC_FLAG2_WPRED | CODEC_FLAG2_8X8DCT | CODEC_FLAG2_FASTPSKIP; c-keyint_min = 25; c-refs = 3; c-trellis=1; c-directpred = 1; c-weighted_p_pred=2; } I am probably not setting the dts and pts values which I believed ffmpeg should be setting it for me.

• What music streaming app fits my needs on Ubuntu?

  - by Jim

  I'm looking for an application to stream Internet radio on Ubuntu. I like listening to Radio Paradise while I work. Right now, I'm using Amarok. "Movie Player" sometimes refuses to open the stream, and VLC doesn't keep its window title updated with the currently playing track. Amarok has nice translucent notifications when tracks change, but track changes in streams don't trigger the notifications. Mostly, I want something that reliably opens streams and makes it easy to see the name of the track that's playing. If it has a built-in directory of streaming radio stations, that would be a big benefit.

• Android - determine specific locations (X,Y coordinates) on a Bitmap on different resolutions?

  - by Mike

  My app that I am trying to create is a board game. It will have one bitmap as the board and pieces that will move to different locations on the board. The general design of the board is square, has a certain number of columns and rows and has a border for looks. Think of a chess board or scrabble board. Before using bitmaps, I first created the board and boarder by manually drawing it - drawLine & drawRect. I decided how many pixels in width the border would be based on the screen width and height passed in on "onSizeChanged". The remaining screen I divided by the number of columns or rows I needed. For examples sake, let's say the screen dimensions are 102 x 102. I may have chosen to set the border at 1 and set the number of rows & columns at 10. That would leave 100 x 100 left (reduced by two to account for the top & bottom border, as well as left/right border). Then with columns and rows set to 10, that would leave 10 pixels left for both height and width. No matter what screen size is passed in, I store exactly how many pixels in width the boarder is and the height & width of each square on the board. I know exactly what location on the screen to move the pieces to based on a simple formula and I know exactly what cell a user touched to make a move. Now how does that work with bitmaps? Meaning, if I create 3 different background bitmaps, once for each density, won't they still be resized to fit each devices screen resolution, because from what I read there were not just 3 screen resolutions, but 5 and now with tablets - even more. If I or Android scales the bitmaps up or down to fit the current devices screen size, how will I know how wide the border is scaled to and the dimensions of each square in order to figure out where to move a piece or calculate where a player touched. So far the examples I have looked at just show how to scale the overall bitmap and get the overall bitmaps width and height. But, I don't see how to tell how many pixels wide or tall each part of the board would be after it was scaled. When I draw each line and rectangle myself based in the screen dimensions from onSizeChanged, I always know these dimensions. If anyone has any sample code or a URL to point me to that I can a read about this with bitmaps, I would appreciate it. Thanks, --Mike BTW, here is some sample code (very simplified) on how I know the dimensions of my game board (border and squares) no matter the screen size. Now I just need to know how to do this with the board as a bitmap that gets scaled to any screen size. @Override protected void onSizeChanged(int w, int h, int oldw, int oldh) { intScreenWidth = w; intScreenHeight = h; // Set Border width - my real code changes this value based on the dimensions of w // and h that are passed in. In other words bigger screens get a slightly larger // border. intOuterBorder = 1; /** Reserve part of the board for the boardgame and part for player controls & score My real code forces this to be square, but this is good enough to get the point across. **/ floatBoardHeight = intScreenHeight / 4 * 3; // My real code actually causes floatCellWidth and floatCellHeight to // be equal (Square). floatCellWidth = (intScreenWidth - intOuterBorder * 2 ) / intNumColumns; floatCellHeight = (floatBoardHeight - intOuterBorder * 2) / intNumRows; super.onSizeChanged(w, h, oldw, oldh); }

• How to choose my own filename format for subscribed podcast files?

  - by user14068

  I subscribe to several podcasts where the filenames of the downloaded mp3 files have no particular pattern to them. When I copy the directory of accumulated mp3 files into my mp3 player, the files play in alphabetical order. What I really want is to play the files chronologically by release date. I currently use iTunes on Windows XP to download the files. What I do now is manually rename the files, adding the date in YYYYMMDD format to the start of each filename so that an alphabetical listing of files will correspond to their chronological order when I listen to them later in PocketTunes on my Palm Centro. Is there some way to get the release date into the filename automatically? If so, I could automate or possibly skip the file renaming step. I would switch from iTunes to something else if that would solve my problem. The file creation time on my local disk isn't a reliable indicator because sometimes I download a few days worth of content at one time, and the files don't necessarily get downloaded in chronological order.

• ActionScript MovieClip moves to the left, but not the right

  - by Defcon

  I have a stage with a movie clip with the instance name of "mc". Currently I have a code that is suppose to move the player left and right, and when the left or right key is released, the "mc" slides a little bit. The problem I'm having is that making the "mc" move to the left works, but the exact some code used for the right doesn't. All of this code is present on the Main Stage - Frame One //Variables var mcSpeed:Number = 0;//MC's Current Speed var mcJumping:Boolean = false;//if mc is Jumping var mcFalling:Boolean = false;//if mc is Falling var mcMoving:Boolean = false;//if mc is Moving var mcSliding:Boolean = false;//if mc is sliding var mcSlide:Number = 0;//Stored for use when creating slide var mcMaxSlide:Number = 1.6;//Max Distance the object will slide. //Player Move Function p1Move = new Object(); p1Move = function (dir:String, maxSpeed:Number) { if (dir == "left" && _root.mcSpeed<maxSpeed) { _root.mcSpeed += .2; _root.mc._x -= _root.mcSpeed; } else if (dir == "right" && _root.mcSpeed<maxSpeed) { _root.mcSpeed += .2; _root.mc._x += _root.mcSpeed; } else if (dir == "left" && speed>=maxSpeed) { _root.mc._x -= _root.mcSpeed; } else if (dir == "right" && _root.mcSpeed>=maxSpeed) { _root.mc._x += _root.mcSpeed; } } //onEnterFrame for MC mc.onEnterFrame = function():Void { if (Key.isDown(Key.LEFT)) { if (_root.mcMoving == false && _root.mcSliding == false) { _root.mcMoving = true; } else if (_root.mcMoving == true && _root.mcSliding == false) { _root.p1Move("left",5); } } else if (!Key.isDown(Key.LEFT)) { if (_root.mcMoving == true && _root.mcSliding == false) { _root.mcSliding = true; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSlide) { _root.mcSlide += .2; this._x -= .2; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMaxSlide) { _root.mcMoving = false; _root.mcSliding = false; _root.mcSlide = 0; _root.mcSpeed = 0; } } else if (Key.isDown(Key.RIGHT)) { if (_root.mcMoving == false && _root.mcSliding == false) { _root.mcMoving = true; } else if (_root.mcMoving == true && _root.mcSliding == false) { _root.p1Move("right",5); } } else if (!Key.isDown(Key.RIGHT)) { if (_root.mcMoving == true && _root.mcSliding == false) { _root.mcSliding = true; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide<_root.mcMaxSpeed) { _root.mcSlide += .2; this._x += .2; } else if (_root.mcMoving == true && _root.mcSliding == true && _root.mcSlide>=_root.mcMax) { _root.mcMoving = false; _root.mcSliding = false; _root.mcSlide = 0; _root.mcSpeed = 0; } } }; I just don't get why when you press the left arrow its works completely fine, but when you press the right arrow it doesn't respond. It is literally the same code.

• Setting font size of Closed Captions on iPhone

  - by forthrin

  Does anyone know if it's possible to control the font size on videos played in the built-in iPhone video player? The subtitles (or "Closed Captions") that are there by default are rather small. None of the attempts below change the font size at all: ffmpeg -y -i in.mkv -i in.srt -map 0:0 -map 0:1 -map 1:0 -vcodec copy -acodec aac -ab 256k -scodec mov_text -strict -2 -metadata title="Title" -metadata:s:s:0 language=eng out.mp4 sudo port install mplayer +mencoder_extras +osd mencoder in.mkv -sub in.srt -o out.mp4 -ovc copy -oac faac -faacopts br=256:mpeg=4:object=2 -channels 2 -srate 48000 -subfont-text-scale 10 -of lavf -lavfopts format=mp4 mp4box -add output.ttxt:hdlr=sbtl:size=50 output.mp4 Should we assume that iOS simply disregards size information, or has anyone ever seen styling of subtitles actually work on iOS? Anyone know how to make this work?

• How does one switch tracks in Windows 8.1's XBox Music app?

  XBox Music Now Playing In the XBox Music app (both app and Windows completely updated) I tried playing a folder full of MP3s from a USB HDD.

Now suppose I want to start playing the sixth track So Hard, how do I do it without pressing the Next Track button five times? Double-clicking (using touch) doesn't work and selecting the track by swiping left or right doesn't show any Play Now option in the bar that pops up from the bottom.

• Windows 7: blue faces in VLC... sometimes

  - by Mala

  There are a bunch of forum posts about this issue from the last several years but no resolution that I could find. I have the newest VLC installed on Windows 7 with the newest nvidia drivers. Suddenly, VLC plays some videos in such a way as faces are blue. When viewed in another media player, or when looking at the thumbnails, this is not an issue. Other videos are not affected. I've tried resetting VLC options, deleting the VLC folder in the AppData area, etc. I have no other color issues. Does anyone have a fix?

• Route global shortcuts to pages opened in Firefox

  - by zamza

  I like listening to music online on sites like stereomood.com. There is a major problem, however. I can not control the player with my keyboard. And even with a mouse - when I want to play/pause I must activate firefox window, select the tab where music plays and hit play/pause button manually - this is a pain, especially when you play a fullscreen game that can not minimize itself. Thus said, global keyboard shortcuts would be a perfect solution. I understand that different online media players have different controls and each site must be configured individually (like, select button with id 'play' and press it), but I believe that can be done in principle. I also guess that such tricks are impossible without some third-party native app which captures shortcuts and routes them to Firefox window. So, any solutions? Maybe some AutoHotkey hacks or similar.

• How to play SWF files without browser

  - by Mehper C. Palavuzlar

  I like to play some downloaded Shockwave Flash (.SWF) files without opening my internet browser. Sometime ago, I remember I could do it just double clicking on the SWF item. Then it was opening in a plain Shockwave window. Now XP won't play ball. I tried Folder Options > File types but couldn't find the associated player exe. How can I surpass this? Edit: There has to be some way to do this without a 3rd party software since I can already play SWFs on my browsers.
