apple.avfoundation.AVOutputSettingsAssistant

All Implemented Interfaces:

NSObject

public class AVOutputSettingsAssistant
extends NSObject

AVOutputSettingsAssistant

A class, each instance of which specifies a set of parameters for configuring objects that use output settings dictionaries, for example AVAssetWriter & AVAssetWriterInput, so that the resulting media file conforms to some specific criteria

Instances of AVOutputSettingsAssistant are typically created using a string constant representing a specific preset configuration, such as AVOutputSettingsPreset1280x720. Once you have an instance, its properties can be used as a guide for creating and configuring an AVAssetWriter object and one or more AVAssetWriterInput objects. If all the suggested properties are respected, the resulting media file will conform to the criteria implied by the preset. Alternatively, the properties of an instance can be used as a "base" configuration which can be customized to suit your individual needs.

The recommendations made by an instance get better as you tell it more about the format of your source data. For example, if you set the sourceVideoFormat property, the recommendation made by the videoSettings property will ensure that your video frames are not scaled up from a smaller size.

setSourceAudioFormat

public void setSourceAudioFormat(CMFormatDescriptionRef value)

[@property] sourceAudioFormat

A CMAudioFormatDescription object describing the format of you audio data

Setting this property will allow the receiver to make a more informed recommendation for the audio settings that should be used. After setting this property, you should re-query the audioSettings property to get the new recommendation. The default value is NULL, which means that the receiver does not know anything about the format of your audio data.

If you set a non-NULL value for this property, and are using the receiver to initialize an AVAssetWriterInput, the same format description should be used to initialize the AVAssetWriterInput, along with the dictionary from the audioSettings property.

setSourceVideoAverageFrameDuration

public void setSourceVideoAverageFrameDuration(CMTime value)

[@property] sourceVideoAverageFrameDuration

A CMTime describing the average frame duration (reciprocal of average frame rate) of your video data

Setting this property will allow the receiver to make a more informed recommendation for the video settings that should be used. After setting this property, you should re-query the videoSettings property to get the new recommendation.

The default value is 1/30, which means that the receiver is assuming that your source video has an average frame rate of 30fps.

It is an error to set this property to a value that is not positive or not numeric. See CMTIME_IS_NUMERIC.

setSourceVideoFormat

public void setSourceVideoFormat(CMFormatDescriptionRef value)

[@property] sourceVideoFormat

A CMVideoFormatDescription object describing the format of your video data

Setting this property will allow the receiver to make a more informed recommendation for the video settings that should be used. After setting this property, you should re-query the videoSettings property to get the new recommendation. The default value is NULL, which means that the receiver does not know anything about the format of your video data.

If you set a non-NULL value for this property, and are using the receiver to initialize an AVAssetWriterInput, the same format description should be used to initialize the AVAssetWriterInput, along with the dictionary from the videoSettings property.

setSourceVideoMinFrameDuration

public void setSourceVideoMinFrameDuration(CMTime value)

[@property] sourceVideoMinFrameDuration

A CMTime describing the minimum frame duration (reciprocal of the maximum frame rate) of your video data

Setting this property will allow the receiver to make a more informed recommendation for the video settings that should be used. After setting this property, you should re-query the videoSettings property to get the new recommendation.

If your source of video data is an instance of AVAssetReaderOutput, you can discover the minimum frame duration of your source asset using the AVAssetTrack.minFrameDuration property.

The default value is 1/30, which means that the receiver is assuming that your source video has a maximum frame rate of 30fps.

It is an error to set this property to a value that is not positive or not numeric. See CMTIME_IS_NUMERIC.

sourceAudioFormat

public CMFormatDescriptionRef sourceAudioFormat()

[@property] sourceAudioFormat

A CMAudioFormatDescription object describing the format of you audio data

Setting this property will allow the receiver to make a more informed recommendation for the audio settings that should be used. After setting this property, you should re-query the audioSettings property to get the new recommendation. The default value is NULL, which means that the receiver does not know anything about the format of your audio data.

If you set a non-NULL value for this property, and are using the receiver to initialize an AVAssetWriterInput, the same format description should be used to initialize the AVAssetWriterInput, along with the dictionary from the audioSettings property.

sourceVideoAverageFrameDuration

public CMTime sourceVideoAverageFrameDuration()

[@property] sourceVideoAverageFrameDuration

A CMTime describing the average frame duration (reciprocal of average frame rate) of your video data

Setting this property will allow the receiver to make a more informed recommendation for the video settings that should be used. After setting this property, you should re-query the videoSettings property to get the new recommendation.

The default value is 1/30, which means that the receiver is assuming that your source video has an average frame rate of 30fps.

It is an error to set this property to a value that is not positive or not numeric. See CMTIME_IS_NUMERIC.

sourceVideoFormat

public CMFormatDescriptionRef sourceVideoFormat()

[@property] sourceVideoFormat

A CMVideoFormatDescription object describing the format of your video data

Setting this property will allow the receiver to make a more informed recommendation for the video settings that should be used. After setting this property, you should re-query the videoSettings property to get the new recommendation. The default value is NULL, which means that the receiver does not know anything about the format of your video data.

If you set a non-NULL value for this property, and are using the receiver to initialize an AVAssetWriterInput, the same format description should be used to initialize the AVAssetWriterInput, along with the dictionary from the videoSettings property.

sourceVideoMinFrameDuration

public CMTime sourceVideoMinFrameDuration()

[@property] sourceVideoMinFrameDuration
