I've dropped Apple's Product Security team an email as it appears there's something wrong with the updater logic on Windows 10 (this is potentially true for Windows 8 and 8.1 as well as the Apple Websites only states the update is for Windows Vista and 7).Update: Apple have responded with the following: I've responded to Apple asking if they plan to release 7.7.8 for newer Operating Systems and will await their response. Workaround The update can be downloaded directly from Apple's website.However on Windows 8 Quick Time advised me that I was "up-to-date", whilst the Apple Software Update advised me that I need to update to 7.7.8.Windows 7 and Windows 8 with Quick Time 7.7.7 installed Quick Time advised I was "up-to-date" whilst the Apple Software Updater identified that updates to 7.7.8 were available.I've also contacted Secunia to see if they're able to provide any breakdown on unpatched Quick Time vs. A few weeks ago this wouldn't install for me, stating something about only working on Windows 7 or Vista, however it appears something has changed and it is installing correctly now on Windows 7, 8, 8.1 and 10.
The company declined to comment to Reuters on the Windows vulnerability, although the DHS notes that the flaws aren't found in the Mac version of the software, which continues to be updated as normal. Our stewardship has been a blast but it's time for all of us to move on. Our preferences were minimal, updating was easy, and we gradually grew the product to add in extras like subtitles and different formats. Today, Perian stands as complete as it ever will be under our stewardship. As an example, we would have liked an official, flexible, and well-documented import API to speed up MKV. Still, we reached a great stopping point and Perian's installed userbase proves how valuable this tool became to so many people. Our team has attained that goal and with that in mind, Perian will be retired soon.It appears the different versions of Windows respond in different ways with Quick Time 7.7.6 and 7.7.7.Windows 7 with Quick Time 7.7.6 installed both Quick Time and the Apple Software Update tool identified that updates were available.
Perian has to read in the entire file in order for seeking and playback to work.
