  • ffmpeg - How to determine if -movflags faststart is enabled? PHP

    - by IIIOXIII
    While I am able to encode an mp4 file which I can plan on my local windows machine, I am having trouble encoding files to mp4 which are readable when streaming by safari, etc. After a bit of reading, I believe my issue is that I must move the metadata from the end of the file to the beginning in order for the converted mp4 files to be streamable. To that end, I am trying to find out if the build of ffmpeg that I am currently using is able to use the -movflags faststart option through php - as my current outputted mp4 files are not working when streamed online. This is the way I am now echoing the -help, -formats, -codecs, but I am not seeing anything about -movflags faststart in any of the lists: exec($ffmpegPath." -help", $codecArr); for($ii=0;$ii<count($codecArr);$ii++){ echo $codecArr[$ii].'</br>'; } Is there a similar method of determining if -movflags fastart is available to my ffmpeg build? Any other way? Should it be listed with any of the previously suggested commands? -help/-formats? Can someone that knows it is enabled in their version of ffmpeg check to see if it is listed under -help or -formats, etc.? TIA.

  • Ubuntu and Belkin N150 f6d4050 Wireless USB adapter v2

    - by Andrew
    I'm new to Ubuntu, and I'm trying to get my Belkin USB adapter to work. There are plenty of discussions out there already about this, but none really helped me out. Here's what I've done - Installed ndiswrapper Installed ndisgtk Installed the driver (rt2870.inf) via ndisgtk ndisgtk reported that the driver was installed and the hardware was present. The green light on the adapter is solid green, which I assume means that Ubuntu is aware of it's presence. However, when I click the little wireless symbol at the navigation bar, there's no option to choose my adapter (assuming that it's supposed to show up there...) My adapter version is F6D4050 - Where do I go from here? I'm a Ubuntu newb, so speak slowly. :P lsusb - andrew@ubuntu:~$ lsusb Bus 002 Device 003: ID 046d:c517 Logitech, Inc.

  • How to change mouse pointer icon in Xfce Debian 7 Wheezy?

    - by kadaj
    I copied the cursor theme (oxy-neon or Oxygen Neon) to /usr/share/icons and from Applications Menu - Settings - Mouse, I am able to see the new theme. I clicked on it and the pointer doesn't change. However the text typing icon ('I'), busy icon, hand icon, and resize window icons got changed. The pointer icon remains the same, the black Adwaita. I removed the Adwaita folder from the icons folder, and still the mouse pointer doesn't change. Is the pointer theme specified elsewhere? I have no setting under home directory. I tried logging out, restart, restarting xfwm4, but nothing works. I just found that the icon pointer changes when the pointer is inside Firefox, but it's not consistent. It keeps changing when I click menu items. Very weird. Any idea how to fix this? This is the output of running: gsettings list-recursively org.gnome.desktop.interface : ~$ gsettings list-recursively org.gnome.desktop.interface org.gnome.desktop.interface automatic-mnemonics true org.gnome.desktop.interface buttons-have-icons false org.gnome.desktop.interface can-change-accels false org.gnome.desktop.interface clock-format '24h' org.gnome.desktop.interface clock-show-date false org.gnome.desktop.interface clock-show-seconds false org.gnome.desktop.interface cursor-blink true org.gnome.desktop.interface cursor-blink-time 1200 org.gnome.desktop.interface cursor-blink-timeout 10 org.gnome.desktop.interface cursor-size 24 org.gnome.desktop.interface cursor-theme 'Adwaita' org.gnome.desktop.interface document-font-name 'Sans 11' org.gnome.desktop.interface enable-animations true org.gnome.desktop.interface font-name 'Cantarell 11' org.gnome.desktop.interface gtk-color-palette 'black:white:gray50:red:purple:blue:light blue:green:yellow:orange:lavender:brown:goldenrod4:dodger blue:pink:light green:gray10:gray30:gray75:gray90' org.gnome.desktop.interface gtk-color-scheme '' org.gnome.desktop.interface gtk-im-module '' org.gnome.desktop.interface gtk-im-preedit-style 'callback' org.gnome.desktop.interface gtk-im-status-style 'callback' org.gnome.desktop.interface gtk-key-theme 'Default' org.gnome.desktop.interface gtk-theme 'Adwaita' org.gnome.desktop.interface gtk-timeout-initial 200 org.gnome.desktop.interface gtk-timeout-repeat 20 org.gnome.desktop.interface icon-theme 'gnome' org.gnome.desktop.interface menubar-accel 'F10' org.gnome.desktop.interface menubar-detachable false org.gnome.desktop.interface menus-have-icons false org.gnome.desktop.interface menus-have-tearoff false org.gnome.desktop.interface monospace-font-name 'Monospace 11' org.gnome.desktop.interface show-input-method-menu true org.gnome.desktop.interface show-unicode-menu true org.gnome.desktop.interface text-scaling-factor 1.0 org.gnome.desktop.interface toolbar-detachable false org.gnome.desktop.interface toolbar-icons-size 'large' org.gnome.desktop.interface toolbar-style 'both-horiz' org.gnome.desktop.interface toolkit-accessibility false ~$

  • Guaranteed semaphore order?

    - by Steve_
    The documentation for the .NET Semaphore class states that: There is no guaranteed order, such as FIFO or LIFO, in which blocked threads enter the semaphore. In this case, if I want a guaranteed order (either FIFO or LIFO), what are my options? Is this something that just isn't easily possible? Would I have to write my own Semaphore? I assume that would be pretty advanced? Thanks, Steve

  • Free video capture programs for windows 7?

    - by chobo2
    I want to record my screen to make a tutorial. I tried to use camStudio but it goes all weird after a couple mins. Like I am recording then all of a sudden a popup from windows says that all the memory for colors is being used and it will stop using areo. Then a few mins later my screen starts going nuts and it starts flashing green. So I am not sure what to record and I can't afford to buy Camtasia.

  • PHP Equivalent of Java Type-Casting Solution

    - by stjowa
    Since PHP has no custom-class type-casting, how would I go about doing the PHP equivalent of this Java code: CustomBaseObject cusBaseObject = cusBaseObjectDao.readCustomBaseObjectById(id); ((CustomChildObject) cusBaseObject).setChildAttribute1(value1); ((CustomChildObject) cusBaseObject).setChildAttribute2(value2); In my case, it would very nice if I could do this. However, trying this without type-casting support, it gives me an error that the methods do not exist for the object. Thanks, Steve

  • XVal validation framework

    - by csetzkorn
    Hi, I started using this validation framework: http://blog.stevensanderson.com/2009/01/10/xval-a-validation-framework-for-aspnet-mvc/ Steve mentions that the DataAnnotationsValidationRunner implementation is slightly naive. Why is this and are there better implementations? I am also looking for a good example that uses this framework to validate database dependent business rules. Any pointers would be very much appreciated. Thanks. Christian

  • Is it worth putting high-performance drives in a home NAS?

    - by Jon M
    I'm looking at a QNAP NAS setup, and in the options for disks they have the very enterprisey Western Digital RE3. I'll be using the box for backing up my laptop, and streaming media either to the laptop or a media device using the built-in media server, possibly both at once. My question is, would I notice any benefit at all in splashing out for the high-performance drive, or should I stick with something quiet and cool (and cheap) like the Caviar Green?

  • Conceal packet loss in PCM stream

    - by ZeroDefect
    I am looking to use 'Packet Loss Concealment' to conceal lost PCM frames in an audio stream. Unfortunately, I cannot find a library that is accessible without all the licensing restrictions and code bloat (...up for some suggestions though). I have located some GPL code written by Steve Underwood for the Asterisk project which implements PLC. There are several limitations; although, as Steve suggests in his code, his algorithm can be applied to different streams with a bit of work. Currently, the code works with 8kHz 16-bit signed mono streams. Variations of the code can be found through a simple search of Google Code Search. My hope is that I can adapt the code to work with other streams. Initially, the goal is to adjust the algorithm for 8+ kHz, 16-bit signed, multichannel audio (all in a C++ environment). Eventually, I'm looking to make the code available under the GPL license in hopes that it could be of benefit to others... Attached is the code below with my efforts. The code includes a main function that will "drop" a number of frames with a given probability. Unfortunately, the code does not quite work as expected. I'm receiving EXC_BAD_ACCESS when running in gdb, but I don't get a trace from gdb when using 'bt' command. Clearly, I'm trampimg on memory some where but not sure exactly where. When I comment out the *amdf_pitch* function, the code runs without crashing... int main (int argc, char *argv[]) { std::ifstream fin("C:\\cc32kHz.pcm"); if(!fin.is_open()) { std::cout << "Failed to open input file" << std::endl; return 1; } std::ofstream fout_repaired("C:\\cc32kHz_repaired.pcm"); if(!fout_repaired.is_open()) { std::cout << "Failed to open output repaired file" << std::endl; return 1; } std::ofstream fout_lossy("C:\\cc32kHz_lossy.pcm"); if(!fout_lossy.is_open()) { std::cout << "Failed to open output repaired file" << std::endl; return 1; } audio::PcmConcealer Concealer; Concealer.Init(1, 16, 32000); //Generate random numbers; srand( time(NULL) ); int value = 0; int probability = 5; while(!fin.eof()) { char arr[2]; fin.read(arr, 2); //Generate's random number; value = rand() % 100 + 1; if(value <= probability) { char blank[2] = {0x00, 0x00}; fout_lossy.write(blank, 2); //Fill in data; Concealer.Fill((int16_t *)blank, 1); fout_repaired.write(blank, 2); } else { //Write data to file; fout_repaired.write(arr, 2); fout_lossy.write(arr, 2); Concealer.Receive((int16_t *)arr, 1); } } fin.close(); fout_repaired.close(); fout_lossy.close(); return 0; } PcmConcealer.hpp /* * Code adapted from Steve Underwood of the Asterisk Project. This code inherits * the same licensing restrictions as the Asterisk Project. */ #ifndef __PCMCONCEALER_HPP__ #define __PCMCONCEALER_HPP__ /** 1. What does it do? The packet loss concealment module provides a suitable synthetic fill-in signal, to minimise the audible effect of lost packets in VoIP applications. It is not tied to any particular codec, and could be used with almost any codec which does not specify its own procedure for packet loss concealment. Where a codec specific concealment procedure exists, the algorithm is usually built around knowledge of the characteristics of the particular codec. It will, therefore, generally give better results for that particular codec than this generic concealer will. 2. How does it work? While good packets are being received, the plc_rx() routine keeps a record of the trailing section of the known speech signal. If a packet is missed, plc_fillin() is called to produce a synthetic replacement for the real speech signal. The average mean difference function (AMDF) is applied to the last known good signal, to determine its effective pitch. Based on this, the last pitch period of signal is saved. Essentially, this cycle of speech will be repeated over and over until the real speech resumes. However, several refinements are needed to obtain smooth pleasant sounding results. - The two ends of the stored cycle of speech will not always fit together smoothly. This can cause roughness, or even clicks, at the joins between cycles. To soften this, the 1/4 pitch period of real speech preceeding the cycle to be repeated is blended with the last 1/4 pitch period of the cycle to be repeated, using an overlap-add (OLA) technique (i.e. in total, the last 5/4 pitch periods of real speech are used). - The start of the synthetic speech will not always fit together smoothly with the tail of real speech passed on before the erasure was identified. Ideally, we would like to modify the last 1/4 pitch period of the real speech, to blend it into the synthetic speech. However, it is too late for that. We could have delayed the real speech a little, but that would require more buffer manipulation, and hurt the efficiency of the no-lost-packets case (which we hope is the dominant case). Instead we use a degenerate form of OLA to modify the start of the synthetic data. The last 1/4 pitch period of real speech is time reversed, and OLA is used to blend it with the first 1/4 pitch period of synthetic speech. The result seems quite acceptable. - As we progress into the erasure, the chances of the synthetic signal being anything like correct steadily fall. Therefore, the volume of the synthesized signal is made to decay linearly, such that after 50ms of missing audio it is reduced to silence. - When real speech resumes, an extra 1/4 pitch period of sythetic speech is blended with the start of the real speech. If the erasure is small, this smoothes the transition. If the erasure is long, and the synthetic signal has faded to zero, the blending softens the start up of the real signal, avoiding a kind of "click" or "pop" effect that might occur with a sudden onset. 3. How do I use it? Before audio is processed, call plc_init() to create an instance of the packet loss concealer. For each received audio packet that is acceptable (i.e. not including those being dropped for being too late) call plc_rx() to record the content of the packet. Note this may modify the packet a little after a period of packet loss, to blend real synthetic data smoothly. When a real packet is not available in time, call plc_fillin() to create a sythetic substitute. That's it! */ /*!

  • Java MVC - How to divide a done text game into MVC?

    - by Zopyrus
    Been sitting here for hours now trying to figure this out, so a bit sympathy for this large question. :) The Goal: I simply want to divide my done code into MVC (Model View Controller) parts. I have the game logics done and text based - the code works fine. The Problem: Well, I want to implement this code into MVC, but where do explain for the MODEL that it should use text-based? Because the VIEW is only for the layout (graphically) correct? I am having a REALLY hard time figuring out where to begin at all. Any pointers would be so nice!

  • Conditional Formatting of a Cell Based on Color Value in that Cell in Excel

    - by Otaku
    Is is possible to format a cell based on one component of the RGB value inside of it. For example, let's say I have 3 cells - A1, A2, A3. In A1, I want the cell color to be the shade of red anywhere between 0 and 255 of the number in the cell (so if it is 128, it should be like half red). For that given cell, the other values will just be 0, 0 (so in this case, zero green and zero blue). Is this possible?
