The container format (mp4 / mov / mkv / m3u8 etc) and audio-video codecs (h.DeckLink capture and playback cards are used every day in the production of television commercials, music videos, episodic television programs and Hollywood feature films.Say your mobile platform supports up to 4K30 video, then you probably need to completely unload the video before playing the next one, as there are limited video decode resources. Memory and video decode resources are typical bottlenecks.This is particularly true for mobile / tablet / portable VR platforms which have more resource constraints than desktops.The system must have sufficient resources to open and decode the media.For example on Vulkan is not a supported graphics API on Android. The correct graphics API must be used, check the platform requirements.For large files we recommend instead streaming from a URL, or downloading it to the persistent storage path and playing from there. On Android if the file is inside the application JAR (from StreamingAssets) and is very large, it may fail to decode because the JAR must be opened and uses a lot of memory.On Android 11 there are changes to folder permissions - see Android article here.On Android make sure Write Permissions in Player Settings is set to External (SDCard).For MP4 files it's best if they're encoded with 'fast start' so they begin streaming immediately.On WebGL make sure there is not a CORS permission issue.On WebGL it's best to use one of the javascript libraries (eg hls.js) for adaptive streaming.On UWP make sure to enable the InternetClient capability option in Player Settings.On Android make sure you have the Internet Accessoption in Player Settings set to require.Platforms often prefer a HTTPS URL and will fail to load a HTTP URL unless forced, see platform notes ( Android, iOS) for details.The Unity application must have permission to access this file.The file cannot be in the /Assets folder unless it is within the /StreamingAssets subfolder.Check that the file is at the location specified. ![]() The file must exist at the specified location.In order for media to play, let's examine all of the conditions that need be true: This is a complicated question to answer, as there are many possible reasons why the media can't be played, and it's not always easy to determine the reason - hence the generic error message. File not found, codec not supported, video resolution too high or insufficient system resources Typically when media fails to load you will see this generic error message: ![]()
