• ffmpeg iOS and SDL2

  24 décembre 2015, par user3487978

  I created a app for iPhone, the core source is based on the latest ffplay.c, I just changed the rendering part to support iOS, general it can play video, but I found the quality is not as good as enough, see screenshot below, the first image is the what expected, the second is image that my app on iPhone produced, and the last the produced by my app on iPad.
  on the iPhone’s image, you can found there is a dash line, and the colour is not correct, it seems that there is a shadow of the image.
  I am new to ffmpeg, can anyone help me what is the problem

• Mobile Analytics SDK : beta release of Piwik iOS SDK

  30 octobre 2013, par Piwik team

  Mattias Levin, a Mobile developer enthusiast from Sweden, has released the first public beta version of the official Piwik SDK for iOS !

  If you are building apps for iOS or OSX, you will be able to track your App usage with Piwik. Learn more in this blog post.

  Apps & Mobile apps Analytics

  Using Piwik to track your app usage would give interesting statistics usage such as :

  • number of active users (per day, week, month, …) of my mobile or desktop app,
  • how long users spend in the app,
  • track which icons, buttons are clicked (or any other custom event),
  • record device info, operating system,
  • reports on any Custom Variables you that are relevant to your app (see examples below),
  • how often is the app opened ? When and how long is the app opened ?
  • number of new users, active users, total users,
  • record errors or exception thrown

  Piwik SDK for iOS
  

  The PiwikTracker is an Objective-C framework (for iOS and OSX) designed to send app usage data to a Piwik analytics server. It is realeased under MIT license. Piwik server is a downloadable, Free/Libre (GPLv3 licensed) real time analytics platform.

  Getting started

  1. Create a new website in the Piwik web interface called “My App”. Copy the Website ID and the token_auth.
  2. Download the PiwikTracker SDK.
  3. Add the PiwikTracker files to your project.
  4. Create and configure the PiwikTracker.
  5. Add code in your app to track screen views, events, exceptions, goals and more
  6. Let the dispatch timer dispatch pending events to the Piwik server, or dispatch events manually.

  For more info, check out the Readme.

  Requirements

  The latest PiwikTracker version uses ARC and support iOS6+ and OSX 10.7+.

  • iOS tracker depends on : Core Data, Core Location, Core Graphics, UIKit and AFNetworking.
  • OSX tracker depends on : Core Data, Core Graphics, Cocoa and AFNetworking.

  Demo project

  The workspace contains an iPhone demo app that uses and demonstrates the features available in the SDK.

  

  Feedback needed

  If you use the iOS SDK to track your app, we would like to hear your suggestions, bug reports or general feedback.

  We hope to work with you to improve the SDK and move it out of beta !

  Please report suggestions, bugs, feature requests in the Github Issues at Piwik iOS SDK.

  Happy App Analytics !

• How do I use -analyzeduration from ffmpeg with FFmpegDecoder.framework from mooncatventures ?

  29 décembre 2013, par user3143010

  I have been playing with the RtspPlay1 from mooncatventures to try and stream a live stream from an ffmpeg streaming source with as little delay as possible. The problem is even when I modify the code to indicate the -analyzedelay 0 flags in RtspPlay1 it does not seem to do anything. I came to this conclusion because the delay is the same on my computer without the -analyzeduration 0 flag as the iOS device. Any thoughts would be helpful.

  Here is the command I am trying to emulate on the iPhone :
  ffplay rtp :///224.1.1.1:11326 -analyzeduration 0

  Here is the modified code I tried with RtspPlay1 :

  forward_argc=1;
  
  
  
  forward_argv[1] = "-analyzeduration";
  
  forward_argv[2] = "0";
  
  //forward_argv[3] = "30";
  
  //forward_argv[4] = "-fast";
  
  //forward_argv[5] = "-sync";
  
  //forward_argv[6] = "video";
  
  //forward_argv[7] = "-drp";
  
  //forward_argv[8] = "-skipidct";
  
  //forward_argv[9] = "10";
  
  //forward_argv[10] = "-skiploop";
  
  //forward_argv[11] = "50";
  
  //forward_argv[12] = "-threads";
  
  //forward_argv[13] = "5";
  
  //argv[14] = "-an";
  
  forward_argv[3] = cString;
  
  
  
  NSLog(@"glflag %@\n ",[parms objectForKey:@"glflag"] );
  
  if ([parms objectForKey:@"glflag"]!=@"1") {
  
     forward_argv[4]="0";
  
  }else {
  
  forward_argv[4]="1";
  
  }
  
  
  
  
  
  forward_argc += 4;
