The following document lists known Pillarbox issues. Entries with a feedback number (FBxxxxxxxx) have been reported to Apple and will hopefully be fixed in upcoming iOS and tvOS releases.
A bug in AVKit currently makes SystemVideoView leak resources after having interacted with the playback button.
No workaround is available yet.
DRM-protected streams do not play in the simulator. This is expected behavior as the required hardware features are not available in the simulator environment.
Use a physical device.
Seeking to the end of an on-demand might confuse the player (FB12020197, FB12019796, FB12019343, FB11970329)
Seeking near the end of a content might sometimes confuse the player (image stuck while sound is still playing, for example).
No workaround is available yet.
When seeking between items very fast the receiver might get confused, not being able to cope with the number of demands and the associated network activity. As a result the receiver might get stuck.
We have mitigated AirPlay instabilities as much as possible so that fast navigation is possible in almost all practical cases. If an issue is encountered, though, closing and reopening the player should make playback possible again.
In some extreme cases it might happen that the AirPlay receiver is unable to recover from heavy usage. If this happens restarting the receiver will make it usable again.
It might happen that attempting to play DRM streams always ends with an error. The reason is likely an issue with key session management.
Kill and restart the application.
Token-protected content cannot be played on old Apple TV 3rd generation devices. An error is returned when attempting to play such content.
No workaround is available yet.
The media type is .unknown if playback is started after an AirPlay session has been established. A correct value is delivered when AirPlay is enabled after playback has already been started, though.
As a result some behaviors based on the media type might not always be reliable over AirPlay.
No workaround is available yet.
The media type can be .unknown if an AirPlay session was established before playback started (see previous issue). In such cases closing the AirPlay session ensures a correct media type is delivered, though for video it might briefly be set to .audio first.
No workaround is available yet.
Pillarbox can be used in iPad applications run on Silicon Macs (Designed for iPad destination) but audios played will have a reported duration of zero. As a result progress reported by ProgressTracker also remains stuck at zero.
No workaround is available yet.
