I am not a musician nor do I create MIDI files. While I did explain the entire sequence of actions in more detail than needed, what I tried to point out was, "Yes, the QT Player ('X' or v10 GUI) does use AV Foundation for playback but Apple decides what forms of data are played back natively, which may be converted, and which will remain totally unsupported." It would appear Apple made a decision many years ago to depreciate QT MIDI support when it removed instrument package and editing features from the "classic" Pro GUI version and has now totally dropped native support in the "modern" version. So, QuickTime Player X uses AV Foundation if it can, and if it can't, it tries to convert it so that it can? (Or just says it can't open it.) Each has its own advantages and disadvantages so I use the software most appropriate for a particular job based on the needs and/or requirements of the project currently in progress. I myself keep QT X, QT 7 Pro, MPEG Streamclip, VLC, HandBrake and a few more installed on my system. Most people I know employ a combination of apps and utilities. Not sure if you are seeking specific capabilities, features, or support structures here. If you believe additional capabilities and/or features of the AV Foundation should be available to an app, then you should file a formal "Bug Report" (developers) and/or send a "Product Feedback" form (general users) requesting changes.Īre there any third-party AVKit player apps that anyone can recommend? Unfortunately, this process is not yet 100% foolproof.Īnd if so, then why is it missing so many features that are included in AV Foundation, such as MIDI playback?Īpple decides which AV Foundation capabilities and features are available to/included in a specific app's GUI. If the data is correctly converted, then control is returned to the original app and the AV Foundation initiates normal playback of the converted media content. Otherwise, control is passed to Convert MacOS structure embed along with the settings required for conversion. If not, the attempt to play the media is terminated and an appropriate modal error message is usually issued based on error trapping results. If not, control is passed to the Modernizer MacOS structure embed to determine if the content is "conversion" compatible with the system as currently configured. I.e., if the combination of media file type and compression format is programmed to be recognized as being compatible with AV Foundation playback, then the content is played. Or does QuickTime Player X use the new APIs?Īs I understand it, "Yes." That is, it uses the AV Foundation structure for playback (and editing if required) of content IFF the content is programmed by Apple as being "compatible" with the app. (I.e., any current Apple multimedia app not based on the classic QT 7 MacOS structure embed.) I would like to get some explanations or support as soon as possible.So, why is there no new AV Foundation player app, showcasing the benefits of the new framework? I thought that I should reach out to Apple Support before I decide to do anything else, because this little error is causing me to not getting any work done. Also I don't want to lose any of my contents or work. I've did some research and try to do some simple steps, but don't want to do anything that might ruined my MacBook. I don't have a lot of stuff on my MacBook Pro yet except for a couple of downloaded music, and I've only had my MacBook Pro for only a year. Q: Do I need to update to macOS Big Sur in order to update QuickTime player?īut I feel like my Mac book pro might not have enough storage for it, and it will likely take up all my storage space. The question that I have is: Why do I need to install QuickTime player when I already have it installed? In the past I've been able to, but as of late I had this issue where an error message will pop up and say that I need to install Apple QuickTime Player before I can import the file. So, just recently I've been unable to import MP3 music files onto my Pro Tools First Program.
