• Does Android 4.x support streaming RTSP over TCP ?

  9 décembre 2014, par Robert

  I’ve used VideoView in Android to play video on wowza successfully. Now I got to deal with my server which the UDP ports seems to be blocked. With the proof of openRTSP command :

  After searching around I found it seems Android still not support RTSP over TCP :

  When streaming to an Android device using RTSP/RTP, the RTP portion
  must flow over UDP. Android doesn’t support RTSP/RTP interleaved (RTP
  over TCP). This means that if UDP is unavailable for RTP playback, RTP
  over TCP won’t work as a failover and your stream won’t play.

  Considering it’s posted on 2010, does Android 4.x support RTSP over TCP now ? I’ve found lots of post asking for how to force transfer via TCP other than UDP. I guess it’s not.

  If not, could I achieve it by re-compiling and using ffmpeg library ?

  Basically I hope ffmpeg could help me to automatically switch to TCP while UDP not available.

• iOS 17’s Impact on Marketing : Navigating Privacy Changes

  22 septembre 2023, par Erin — Analytics Tips, Marketing

  In the ever-evolving landscape of digital marketing, staying up-to-date with the latest changes is paramount. One such significant change came on 18 September 2023, in the form of iOS 17, Apple’s latest operating system update. With iOS 17, Apple has introduced new privacy features that are set to have a profound impact on marketers and how they track and analyse user behaviour. 

  In this blog, we will explore what iOS 17 is, how it affects tracking, which tracking parameters are impacted, what remains unaffected, and most importantly, how marketers can future-proof their campaign tracking URLs.

  What is iOS 17 ?

  iOS 17 is the latest update to Apple’s mobile operating system, used on millions of iPhones worldwide. While iOS updates often bring new features and improvements, iOS 17 has made waves in the digital marketing community due to its emphasis on user privacy.

  How does iOS 17 affect tracking ?

  One of the key features of iOS 17 that concerns marketers is its impact on tracking. Apple’s new update aims to enhance user privacy by limiting the information that can be tracked and collected by third-party entities, particularly through query parameters in URLs. This means that certain tracking mechanisms that marketers have relied on for years are now rendered ineffective on iOS 17 devices.

  Campaign tracking URLs, also known as tracking parameters or UTM parameters, are special codes added to the end of URLs. They are used by marketers to track various aspects of a user’s interaction with a digital marketing campaign. These parameters provide valuable data, such as the source of traffic, the medium through which users arrived and specific campaign details.

  For example, with Matomo (mtm) tracking parameters, a campaign tracking URL might look like this :

  https://www.example.com/products/example_product?mtm_campaign=summer-sale

  

  Understanding the impact of iOS 17 on campaign tracking URLs is essential for marketers who rely on this data to measure the effectiveness of their marketing campaigns.

  Which campaign tracking parameters are affected by iOS 17 ?

  Several tracking parameters commonly used by marketers will no longer work as expected on iOS 17. Some of these include :

  • Facebook (fbclid) : Employed for tracking Facebook advertising campaigns. 
  • Instagram (igshid) : Used to track user interactions with Instagram ads.
  • Google Ads (gclid) : Used to track Google Ads campaigns. 
  • Twitter (twclid) : Used to track user interactions with Twitter ads. 
  • Microsoft Ads (msclkid) : Employed for tracking Microsoft Ads campaigns. 
  • Mailchimp (mc_eid) : Used by Mailchimp for email campaign tracking. 

  These changes are significant, as they disrupt many of the common tracking methods that marketers rely on to measure the effectiveness of their campaigns.

  Which campaign tracking parameters are not affected by iOS 17 ?

  While many tracking parameters have been impacted, there are still some that remain unaffected on iOS 17. However, it’s important to note that the status of these parameters might change in the future as Apple continues to prioritise user privacy. Some of the tracking parameters that are still working as of now include :

  • Matomo (mtm) : Matomo campaign tracking parameters. 
  • Google Analytics (UTMs) : Google Analytics campaign tracking parameters.
  • Pinterest (epik) : Used for tracking Pinterest campaigns. 
  • Klaviyo (_kx) : Klaviyo for email marketing tracking. 
  • TikTok (tt-) : Used for tracking TikTok ad interactions. 
  • Hubspot (hsa) : Used for tracking Hubspot campaigns. 

  While these parameters offer some reprieve for marketers, it’s essential to keep a close eye on any potential changes in their functionality as Apple continues to roll out privacy-friendly features.

  How are Matomo users impacted ?

  Fortunately, Matomo, as a leading privacy-friendly web analytics solution, remains unaffected by the changes introduced by iOS 17. Specifically :

  For Matomo users who rely on mtm or UTMs

  If you’re using Matomo or GA tracking parameters, you can rest assured that iOS 17’s changes won’t affect your tracking capabilities in Matomo.

  Attention to gclids (Google Ads) and msclkid (Bing Ads)

  If you use Google Ads or Bing Ads tracking parameters with Matomo’s Advertising Conversion Export feature for tracking, iOS 17 presents a challenge. Your gclids and msclkids may not provide the same level of tracking accuracy on Apple mobile devices. This is a critical consideration, especially if your ad campaigns target mobile users.

  How to future-proof your campaign tracking

  Given the impact of iOS 17 on tracking, it’s crucial for marketers to adapt and future-proof their campaign tracking strategies. Here are some steps you can take to mitigate the affects of iOS 17 on your marketing campaigns :

  Monitor platform updates

  Expect updates from advertising and analytics platforms in response to Apple’s privacy changes. These platforms are likely to develop alternative tracking methods or adapt existing ones to comply with iOS 17’s restrictions. Stay informed about these updates and incorporate them into your tracking strategy.

  Prioritise privacy-friendly tech stacks

  In the ever-evolving digital marketing landscape, it’s crucial to prioritise privacy-friendly tech stacks. Privacy-friendly tracking tools like Matomo are essential for maintaining trust and respecting user privacy.

  Matomo ensures the privacy of your users and analytics data. When using Matomo, you retain control of your data ; nobody else does. This commitment to user privacy aligns with the changing digital marketing landscape, where privacy is taking centre stage.

  Transition from affected campaign tracking parameters

  If you’ve been using tools like Mailchimp, whose campaign tracking URLs have been affected by iOS 17, consider transitioning to the campaign tracking URL parameters of your analytics solution. Whether you choose Matomo or Google Analytics, these solutions can help you understand how your email marketing campaigns are performing.

  Focus on data privacy compliance

  Embrace data privacy compliance practices. As privacy regulations evolve, it’s essential to prioritise transparency in data collection. Ensure that your tracking methods align with privacy standards to maintain trust with your audience.

  Regularly review and adapt

  The digital marketing landscape is dynamic, and iOS 17 is just one example of how quickly things can change. Regularly review your tracking methods and adapt to new developments in the industry. Staying agile and informed is key to long-term success.

  Marketers’ path forward

  iOS 17 has reshaped mobile user privacy, challenging marketers to adapt. While some tracking parameters are affected, savvy marketers can still thrive by embracing unique tracking solutions, staying informed about platform updates, and prioritising data privacy.
