 	The timing information in the sample buffer, considered relative to the time passed to -[AVAssetWriter startSessionAtSourceTime:], will be used to determine the timing of those samples in the output file.
- 
+
+	For track types other than audio tracks, to determine the duration of all samples in the output file other than the very last sample that's appended, the difference between the sample buffer's output DTS and the following sample buffer's output DTS will be used. The duration of the last sample is determined as follows:
+	1. If a marker sample buffer with kCMSampleBufferAttachmentKey_EndsPreviousSampleDuration is appended following the last media-bearing sample, the difference between the output DTS of the marker sample buffer and the output DTS of the last media-bearing sample will be used.
+	2. If the marker sample buffer is not provided and if the output duration of the last media-bearing sample is valid, it will be used.
+	3. if the output duration of the last media-bearing sample is not valid, the duration of the second-to-last sample will be used.
+
+	For audio tracks, the properties of each appended sample buffer are used to determine corresponding output durations.
+
 	The receiver will retain the CMSampleBuffer until it is done with it, and then release it.  Do not modify a CMSampleBuffer or its contents after you have passed it to this method.
  
 	If the sample buffer contains audio data and the AVAssetWriterInput was intialized with an outputSettings dictionary then the format must be linear PCM. If the outputSettings dictionary was nil then audio data can be provided in a compressed format, and it will be passed through to the output without any re-compression. Note that advanced formats like AAC will have encoder delay present in their bitstreams. This data is inserted by the encoder and is necessary for proper decoding, but it is not meant to be played back. Clients who provide compressed audio bitstreams must use kCMSampleBufferAttachmentKey_TrimDurationAtStart to mark the encoder delay (generally restricted to the first sample buffer). Packetization can cause there to be extra audio frames in the last packet which are not meant to be played back. These remainder frames should be marked with kCMSampleBufferAttachmentKey_TrimDurationAtEnd. CMSampleBuffers obtained from AVAssetReader will already have the necessary trim attachments. Please see http://developer.apple.com/mac/library/technotes/tn2009/tn2258.html for more information about encoder delay. When attaching trims make sure that the output PTS of the sample buffer is what you expect. For example if you called -[AVAssetWriter startSessionAtSourceTime:kCMTimeZero] and you want your audio to start at time zero in the output file then make sure that the output PTS of the first non-fully trimmed audio sample buffer is kCMTimeZero.

  @discussion
     On a receiver where -isLensStabilizationDuringBracketedCaptureSupported returns YES, lens stabilization may be applied to the bracket to reduce blur commonly found in low light photos. When lens stabilization is enabled, bracketed still image captures incur additional latency. Lens stabilization is more effective with longer-exposure captures, and offers limited or no benefit for exposure durations shorter than 1/30 of a second. It is possible that during the bracket, the lens stabilization module may run out of correction range and therefore will not be active for every frame in the bracket. Each emitted CMSampleBuffer from the bracket will have an attachment of kCMSampleBufferAttachmentKey_StillImageLensStabilizationInfo indicating additional information about stabilization was applied to the buffer, if any. The default value of -isLensStabilizationDuringBracketedCaptureEnabled is NO. This value will be set to NO when -isLensStabilizationDuringBracketedCaptureSupported changes to NO.
