AVFoundation errors -16357 and -16356

Hello, I'm getting occasional undocumented errors when appending video buffers to an AVAssetWriter.


They're -16357 and -16356. Also sometimes -16364, but that was documented by @bford as being related to invalid timestamps.


Can anyone shed some light on these? Are they also related to timestamps?


Thanks,

RF.
