  • A seekable one-frame FLV video (with audio)?

    Is it possible to generate an FLV out of an MP3 and a JPG, without uselessly looping the image and still be able to seek the audio ? This command generates a non-seekable video: ffmpeg -y -i audio.mp3 -i image.jpg -r 1 -acodec copy video.flv and this one generates a seekable one, but with uselessly looping the image occupying both space and time: ffmpeg -y -loop_input -i audio.mp3 -i image.jpg -r 1 -acodec copy video.flv -shortest

  • Frame rate upsampling codec/player/software?

    - by djechelon
    Hello, I recently noticed that when I play both HD and SD videos on my HDMI TV at 1080p 60Hz from my computer, the motion is not fluid as I would expect. As far as I know, it could be because the 24fps video needs to be upsampled by the codec to match the 60Hz output of the monitor. But, as far as I know, the upsampling is done by simply repeating each photogram for a certain amount of frames. I usually play MKV videos with VLC. Do you know if there is a player or codec that performs the upsampling by interpolation like some 100Hz TVs do? I recently saw an LG led TV play a 24fps 720p video at 100Hz with an incredible motion fluidity, and I simply wonder why can't my computer do! I have an NVidia card. Does PureVideo help? I'm a noob with these things. Thank you.

  • Tcp window size won't go above 130048

    - by Roger
    I have 2 servers set up with about 80ms latency between them. Both are centos 6 and run a java app that transfers data from on location to another. Both are on 1gbps connections. I have been trying different sysctl settings and different send & receive buffer settings in java but no matter what I set them to, I cannot get the tcp window size to go above 130048 in the tcp dumps. This equates to roughly 13mbps which is the actual throughput I am getting.

  • XDCAM HD 422 frame setting

    - by sebastian
    I have a question that you can hopefully answer me. I am trying to write a ffmpeg script that transcodes my clips in XDCAM HD 422 1080p24, and it works fine as long as the original file has 24 fps, but is there a way that I can set an option which says "even if the original file has 25 fps I will transcode it in 24 fps". I have tried it, like I said it works fine as long as the original clip has 24 frames, but as soon as the original clip has another framerate, he can not convert it to 24 frames. I have tried using -r 24 which normally settles the framerate, but here it doesn't work. I am using the -vtag xd5c

  • Write a signal handler to catch SIGSEGV

    - by Adi
    Hi all, I want to write a signal handler to catch SIGSEGV. First , I would protect a block of memory for read or writes using char *buffer; char *p; char a; int pagesize = 4096; " mprotect(buffer,pagesize,PROT_NONE) " What this will do is , it will protect the memory starting from buffer till pagesize for any reads or writes. Second , I will try to read the memory by doing something like p = buffer; a = *p This will generate a SIGSEGV and i have initialized a handler for this. The handler will be called . So far so good. Now the problem I am facing is , once the handler is called, I want to change the access write of the memory by doing mprotect(buffer, pagesize,PROT_READ); and continue my normal functioning of the code. I do not want to exit the function. On future writes to the same memory, I want again catch the signal and modify the write rights and then take account of that event. Here is the code I am trying : #include <signal.h> #include <stdio.h> #include <malloc.h> #include <stdlib.h> #include <errno.h> #include <sys/mman.h> #define handle_error(msg) \ do { perror(msg); exit(EXIT_FAILURE); } while (0) char *buffer; int flag=0; static void handler(int sig, siginfo_t *si, void *unused) { printf("Got SIGSEGV at address: 0x%lx\n",(long) si->si_addr); printf("Implements the handler only\n"); flag=1; //exit(EXIT_FAILURE); } int main(int argc, char *argv[]) { char *p; char a; int pagesize; struct sigaction sa; sa.sa_flags = SA_SIGINFO; sigemptyset(&sa.sa_mask); sa.sa_sigaction = handler; if (sigaction(SIGSEGV, &sa, NULL) == -1) handle_error("sigaction"); pagesize=4096; /* Allocate a buffer aligned on a page boundary; initial protection is PROT_READ | PROT_WRITE */ buffer = memalign(pagesize, 4 * pagesize); if (buffer == NULL) handle_error("memalign"); printf("Start of region: 0x%lx\n", (long) buffer); printf("Start of region: 0x%lx\n", (long) buffer+pagesize); printf("Start of region: 0x%lx\n", (long) buffer+2*pagesize); printf("Start of region: 0x%lx\n", (long) buffer+3*pagesize); //if (mprotect(buffer + pagesize * 0, pagesize,PROT_NONE) == -1) if (mprotect(buffer + pagesize * 0, pagesize,PROT_NONE) == -1) handle_error("mprotect"); //for (p = buffer ; ; ) if(flag==0) { p = buffer+pagesize/2; printf("It comes here before reading memory\n"); a = *p; //trying to read the memory printf("It comes here after reading memory\n"); } else { if (mprotect(buffer + pagesize * 0, pagesize,PROT_READ) == -1) handle_error("mprotect"); a = *p; printf("Now i can read the memory\n"); } /* for (p = buffer;p<=buffer+4*pagesize ;p++ ) { //a = *(p); *(p) = 'a'; printf("Writing at address %p\n",p); }*/ printf("Loop completed\n"); /* Should never happen */ exit(EXIT_SUCCESS); } The problem I am facing with this is ,only the signal handler is running and I am not able to return to the main function after catching the signal.. Any help in this will be greatly appreciated. Thanks in advance Aditya

  • UIScrollView frame size issue in Landscape Mode

    - by viper15
    I'm trying to make UIScrollView auto-resize and appear correctly in Landscape mode. Portrait mode works fine. Here's my code: - (void)viewDidLoad { [super viewDidLoad]; //=== load all the custom view NSMutableArray *controllers = [[NSMutableArray alloc] init]; int page = 0; [controllers addObject:[self loadScrollView:[[Page1ViewController alloc] initWithNibName:@"Page1ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page2ViewController alloc] initWithNibName:@"Page2ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page3ViewController alloc] initWithNibName:@"Page3ViewController" bundle:nil] withPage:page++]]; self.viewControllers = controllers; [controllers release]; //=== automaticaly define number of pages _numberOfPages = [self.viewControllers count]; // a page is the width of the scroll view scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * _numberOfPages, scrollView.frame.size.height); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO; scrollView.scrollsToTop = NO; scrollView.delegate = self; // First, set the number of pages pageControl.numberOfPages = _numberOfPages; pageControl.currentPage = 0; } Then, I went into each view controller nib file and set the background to different color to test if it's working. Unfortunately, when in Landscape mode, the width and height remains the same as in Portrait Mode. I'm not sure how to fix this problem. Hope anyone can help me. Many thanks in advance.

  • NSScrollView frame and flipped documentView

    - by StrAbZ
    Hi, I have problems with NSScrollView, It is not displayed the way I want. Yes I know there is a lot of post about it around the web, I need to override the isFlipped, in order to make it return YES, in my NSView subclass. Ok, it's done, so now, my scrollView scroll from top to bottom, and not in the reverse way, as it was before overriding isFlipped. But, this is the second part, my real problem, which I didn't found any answer on the web, how the hell I'm supposed to code, or create my view in interface builder, if everything is flipped? If I put something at the top, it is displayed a the bottom… do you have any magic trick to handle that? And my last problem, is the NSScrollView frame. before setting the documentView of my scroll view, everything is fine, the scrollView is displayed at the place I choose, but, when I set the document view, it looks like the scrollview frame looks bigger, so I have to resize it…. is this a normal behavior? Thank you very much.

  • Plotting andrews curves of subsets of a data frame on the same plot

    - by user2976477
    I have a data frame of 12 columns and I want to plot andrews curves in R of this data, basing the color of the curves on the 12th columns. Below are a few samples from the data (sorry the columns are not aligned with the numbers) Teacher_explaining Teacher_enthusiastic Teacher_material_interesting Material_stimulating Material_useful Clear_marking Marking_fair Feedback_prompt Feedback_clarifies Detailed_comments Notes Year 80 80 80 80 85 85 80 80 80 80 70 3 70 60 30 40 70 60 30 40 70 0 30 3 100 90 90 80 80 100 100 90 100 100 100 MSc 85 85 85 90 90 70 90 50 70 80 100 MSc 90 50 90 90 90 70 100 50 80 100 100 4 100 80 80 75 90 80 80 50 80 80 90 3 From this data I tried to plot andrews curves using the code below: install.packages("andrews") library(andrews) col <- as.numeric(factor(course[,12])) andrews(course[,1:12], clr = 12) However, the 12th column has three groups (3 types of responses) and I want to group two of them and then plot the andrews curve of the data, without editing my data frame in Excel. x <- subset(course, Year == "MSc" & "4") y <- subset(course, Year == "3") I tried the above code, but my argument for x don't work. "MSc", "3" and "4" are the groups in the 12th column, and I want to group MSc and 4 so that their Andrews curves have the same color. If you have any idea how to do this, please let me know.

  • Simple wxPython Frame Contents Resizing - Ratio?

    - by Wes
    I have a wxPython app with one frame and one panel. On that panel are a number of static boxes, each of which has buttons and textboxes. I have just begun reading about sizers, but they seem like they might be more than what I need, or it could that they are exactly what I need but I don't know how to use them correctly! The frame currently opens at 1920 x 1080. If the user drags the bottom right corner to resize the app, I just want everything to get smaller or larger as needed to keep the same size ratio. Is this possible? Thank you! edit: additional info: I used wxPython 2.8 and Boa to construct the GUI. I am contemplating trying another gui ide. So after reading some more about sizers, I am thinking about doing the following: add a gridsizer and basically divide my window's elements into rows and columns, then set each row and column's size as necessary until I achieve the original layout. Then I guess set the rows and columns to resize correctly? Is this a decent idea?

  • Frame sizing of tableview within nested child controllers/subviews

    - by jwoww
    I'm a bit confused by the proper frame sizing of a table view to fit within my screen. Here's my setup of view controllers within view controllers: UITabBarController UINavigationController as one of the tab bar viewcontrollers; title bar hidden ViewController - a container view controller because I need the option to place some controls beneath the UITableView, sometimes (but not in the current scenario) UITableViewController Now, my question is what the proper frame dimensions of the UITableview should be. Here's what I've got in the ViewController viewDidLoad method. I used subtracted 49.0 (the size of the tab bar) from 480.0. However, this leaves a black bar at the bottom. 20.0 appears to do it (coincidentally?) the size of the status bar, but I don't understand why that would be. Wouldn't the true pixel dimensions of the tableview be 480-49? // MessageTableViewController is my subclass of UITableViewController MessagesTableViewController *vcMessagesTable = [[MessagesTableViewController alloc] init]; CGRect tableViewFrame = CGRectMake(0, 0, 320.0, 480.0 - 49.0); [[vcMessagesTable view] setFrame:tableViewFrame]; self.tableViewController = vcMessagesTable; [self addChildViewController:vcMessagesTable]; [[self view] addSubview:vcMessagesTable.view]; Here's how it looks:

  • Create links programmatically inside an EmberJS view

    - by Michael Gallego
    I have a pretty complex view to render which involves some kind of recursion (the typical folder/file nested list). The fact that it contains heterogeneous objects (folders and files) make it even harder to write Handlebars templates. Therefore, the only solution I've found is to create a view, and manually fill the render buffer. I came with the following solution: App.LibraryContentList = Ember.View.extend({ tagName: 'ol', classNames: ['project-list', 'dd-list'], nameChanged: function() { this.rerender(); }.observes('[email protected]'), render: function(buffer) { // We only start with depth of zero var content = this.get('content').filterProperty('depth', 0); content.forEach(function(item) { this.renderItem(buffer, item); }, this); }, renderItem: function(buffer, item) { switch (item.constructor.toString()) { case 'Photo.Folder': this.renderFolder(buffer, item); break; case 'Photo.File': this.renderFile(buffer, item); break; } }, renderFolder: function(buffer, folder) { buffer.push('<li class="folder dd-item">'); buffer.push('<span class="dd-handle">' + folder.get('name') + '</span>'); // Merge sub folders and files, and sort them by sort order var content = this.mergeAndSort(); if (content.get('length') > 0) { buffer.push('<ol>'); content.forEach(function(item) { this.renderItem(buffer, item); }, this); buffer.push('</ol>'); } buffer.push('</li>'); }, renderFile: function(buffer, album) { buffer.push('<li class="album dd-item">'); buffer.push('<span class="dd-handle">' + file.get('name') + '</span>'); buffer.push('</li>'); } }); Now, what I'd like is to be able to add links so that each folder and each file is clickable and redirect to another route. But how am I supposed to do that, as I don't have access to the linkTo helper? I've tried to play with the LinkView view, but without any success. Should I register handlers manually for each item? I've also thought about breaking that with a CollectionView instead, and splitting the content by depth so that I could render it using templates, but it seems more complicated. Any thoughts?

  • Vim with split frame of buffers or file listing

    - by casualcoder
    Similar in appearance to Vim as a note taking platform (SO), I would like a pane with a list of open buffers that can be used as a jump to list. This is one feature in many IDEs and other advanced editors that is missing. Having a dozen buffers or so open becomes confusing as to which buffer is where.

  • Fastest way to read data from a lot of ASCII files

    - by Alsenes
    Hi guys, for a college exercise that I've already submitted I needed to read a .txt file wich contained a lot of names of images(1 in each line). Then I needed to open each image as an ascii file, and read their data(images where in ppm format), and do a series of things with them. The things is, I noticed my program was taking 70% of the time in the reading the data from the file part, instead of in the other calculations that I was doing (finding number of repetitions of each pixel with a hash table, finding diferents pixels beetween 2 images etc..), which I found quite odd to say the least. This is how the ppm format looks like: P3 //This value can be ignored when reading the file, because all image will be correctly formatted 4 4 255 //This value can be also ignored, will be always 255. 0 0 0 0 0 0 0 0 0 15 0 15 0 0 0 0 15 7 0 0 0 0 0 0 0 0 0 0 0 0 0 15 7 0 0 0 15 0 15 0 0 0 0 0 0 0 0 0 This is how I was reading the data from the files: ifstream fdatos; fdatos.open(argv[1]); //Open file with the name of all the images const int size = 128; char file[size]; //Where I'll get the image name Image *img; while (fdatos >> file) { //While there's still images anmes left, continue ifstream fimagen; fimagen.open(file); //Open image file img = new Image(fimagen); //Create new image object with it's data file ……… //Rest of the calculations whith that image ……… delete img; //Delete image object after done fimagen.close(); //Close image file after done } fdatos.close(); And inside the image object read the data like this: const int tallafirma = 100; char firma[tallafirma]; fich_in >> std::setw(100) >> firma; // Read the P3 part, can be ignored int maxvalue, numpixels; fich_in >> height >> width >> maxvalue; // Read the next three values numpixels = height*width; datos = new Pixel[numpixels]; int r,g,b; //Don't need to be ints, max value is 256, so an unsigned char would be ok. for (int i=0; i<numpixels; i++) { fich_in >> r >> g >> b; datos[i] = Pixel( r, g ,b); } //This last part is the slow one, //I thing I should be able to read all this data in one single read //to buffer or something which would be stored in an array of unsigned chars, //and then I'd only need to to do: //buffer[0] -> //Pixel 1 - Red data //buffer[1] -> //Pixel 1 - Green data //buffer[2] -> //Pixel 1 - Blue data So, any Ideas? I think I can improve it quite a bit reading all to an array in one single call, I just don't know how that is done. Also, is it posible to know how many images will be in the "index file"? Is it posiible to know the number of lines a file has?(because there's one file name per line..) Thanks!!

  • How do I grab hold of a pop-up that is opened from a frame?

    - by KLA
    I am testing a website using WatiN. On one of the pages I get a "report" in an Iframe, within this I frame there is a link to download and save the report. But since the only way to get to the link is to use frame.Link(...) the pop-up closes immediately after opening; Code snippet below //Click the create graph button ie.Button(Find.ById("ctl00_ctl00_ContentPlaceHolder1_TopBoxContentPlaceHolder_btnCreateGraph")).Click(); //Lets export the data ie.Div(Find.ById("colorbox")); ie.Div(Find.ById("cboxContent")); ie.Div(Find.ById("cboxLoadedContent")); Thread.Sleep(1000);//Used to cover performance issues Frame frame = ie.Frame(Find.ByName(frameNameRegex)); for (int Count = 0; Count < 10000000; Count++) {double nothing = (Count/12); }//Do nothing I just need a short pause //SelectList waits for a postback which does not occur. try { frame.SelectList(Find.ById("rvReport_ctl01_ctl05_ctl00")).SelectByValue("Excel"); } catch (Exception) { //Do nothing } //Now click export frame.Link(Find.ById("rvReport_ctl01_ctl05_ctl01")).ClickNoWait(); IE ieNewBrowserWindow = IE.AttachTo<IE>(Find.ByUrl(urlRegex)); fileDownloadHandler.WaitUntilFileDownloadDialogIsHandled(150); fileDownloadHandler.WaitUntilDownloadCompleted(200); I have tried using ie instead of frame which is why all those ie.Div's are present. if I use frame the pop-up window opens and closes instantly. If I use ie I get a link not found error. If I click on the link manually, while the test is "trying to find the link" the file will download correctly.

  • unsigned char* buffer (FreeType2 Bitmap) to System::Drawing::Bitmap.

Formating 114 Frames... starting loop making encoder Frame 1 process 1 Frame 1 process 2 Frame 1 process 2.5 This is the error: Traceback (most recent call last): File "ScreenCapture.py", line 202, in <module> makeVideoUpdated(record_files, video_file) File "ScreenCapture.py", line 151, in makeVideoUpdated d = enc.encode(da) pymedia.video.vcodec.VCodecError: Failed to encode frame( error code is 0 ) This is my code: def makeVideoUpdated(files, outFile, outCodec='mpeg1video', info1=0.1): fw = open(outFile, 'wb') if (fw == None) : print "Cannot open file " + outFile return if outCodec == 'mpeg1video' : bitrate= 2700000 else: bitrate= 9800000 start = time.time() enc = None frame = 1 print "Formating "+str(len(files))+" Frames..." print "starting loop" for img in files: if enc == None: print "making encoder" params= {'type': 0, 'gop_size': 12, 'frame_rate_base': 125, 'max_b_frames': 90, 'height': img.get_height(), 'width': img.get_width(), 'frame_rate': 90, 'deinterlace': 0, 'bitrate': bitrate, 'id': vcodec.getCodecID(outCodec) } enc = vcodec.Encoder(params) # Create VFrame print "Frame "+str(frame)+" process 1" bmpFrame= vcodec.VFrame(vcodec.formats.PIX_FMT_RGB24, img.get_size(), # Covert image to 24bit RGB (pygame.image.tostring(img, "RGB"), None, None) ) print "Frame "+str(frame)+" process 2" # Convert to YUV, then codec da = bmpFrame.convert(vcodec.formats.PIX_FMT_YUV420P) print "Frame "+str(frame)+" process 2.5" d = enc.encode(da) #THIS IS WHERE IT STOPS print "Frame "+str(frame)+" process 3" fw.write(d.data) print "Frame "+str(frame)+" process 4" frame += 1 print "savng file" fw.close() Could somebody tell me why I have this error and possibly how to fix it? The files argument is a list of pygame images, outFile is a path, outCodec is default, and info1 is not used anymore. UPDATE 1 This is the code I used to make that list of pygame images. from PIL import ImageGrab import time, pygame pygame.init() f = [] #This is the list that contains the images fps = 1 for n in range(1, 100): info = ImageGrab.grab() size = info.size mode = info.mode data = info.tostring() info = pygame.image.fromstring(data, size, mode) f.append(info) time.sleep(fps)

  • Drawing a TextBox in an extended Glass Frame (C# w/o WPF)

    - by Lazlo
    I am trying to draw a TextBox on the extended glass frame of my form. I won't describe this technique, it's well-known. Here's an example for those who haven't heard of it: http://www.danielmoth.com/Blog/Vista-Glass-In-C.aspx The thing is, it is complex to draw over this glass frame. Since black is considered to be the 0-alpha color, anything black disappears. There are apparently ways of countering this problem: drawing complex GDI+ shapes are not affected by this alpha-ness. For example, this code can be used to draw a Label on glass (note: GraphicsPath is used instead of DrawString in order to get around the horrible ClearType problem): public class GlassLabel : Control { public GlassLabel() { this.BackColor = Color.Black; } protected override void OnPaint(PaintEventArgs e) { GraphicsPath font = new GraphicsPath(); font.AddString( this.Text, this.Font.FontFamily, (int)this.Font.Style, this.Font.Size, Point.Empty, StringFormat.GenericDefault); e.Graphics.SmoothingMode = SmoothingMode.HighQuality; e.Graphics.FillPath(new SolidBrush(this.ForeColor), font); } } Similarly, such an approach can be used to create a container on the glass area. Note the use of the polygons instead of the rectangle - when using the rectangle, its black parts are considered as alpha. public class GlassPanel : Panel { public GlassPanel() { this.BackColor = Color.Black; } protected override void OnPaint(PaintEventArgs e) { Point[] area = new Point[] { new Point(0, 1), new Point(1, 0), new Point(this.Width - 2, 0), new Point(this.Width - 1, 1), new Point(this.Width -1, this.Height - 2), new Point(this.Width -2, this.Height-1), new Point(1, this.Height -1), new Point(0, this.Height - 2) }; Point[] inArea = new Point[] { new Point(1, 1), new Point(this.Width - 1, 1), new Point(this.Width - 1, this.Height - 1), new Point(this.Width - 1, this.Height - 1), new Point(1, this.Height - 1) }; e.Graphics.FillPolygon(new SolidBrush(Color.FromArgb(240, 240, 240)), inArea); e.Graphics.DrawPolygon(new Pen(Color.FromArgb(55, 0, 0, 0)), area); base.OnPaint(e); } } Now my problem is: How can I draw a TextBox? After lots of Googling, I came up with the following solutions: Subclassing the TextBox's OnPaint method. This is possible, although I could not get it to work properly. It should involve painting some magic things I don't know how to do yet. Making my own custom TextBox, perhaps on a TextBoxBase. If anyone has good, valid and working examples, and thinks this could be a good overall solution, please tell me. Using BufferedPaintSetAlpha. (http://msdn.microsoft.com/en-us/library/ms649805.aspx). The downsides of this method may be that the corners of the textbox might look odd, but I can live with that. If anyone knows how to implement that method properly from a Graphics object, please tell me. I personally don't, but this seems the best solution so far. Thanks!

  • Frame load interrupted error while loading a word document in UIWebView

    - by Mugunth Kumar
    I want to load a word document using UIWebView. I used the code provided in http://developer.apple.com/iphone/library/qa/qa2008/qa1630.html to load the document. But not all the documents load successfully. Sometimes I get an error Error Domain=WebKitErrorDomain Code=102 UserInfo=0x145bc10 "Frame load interrupted" The error seems to be very sporadic and I get this error only for some documents. However the same document loads correctly in mail.app. What am I missing?
