Method Detail

accessInstanceVariablesDirectly

public static boolean accessInstanceVariablesDirectly()

addRequestProcessingOptionsError

public boolean addRequestProcessingOptionsError(VNRequest request,
                                                VNVideoProcessorRequestProcessingOptions processingOptions,
                                                org.moe.natj.general.ptr.Ptr<NSError> error)

Add a VNRequest with the specified processing options to be performed on the video.

This method can be called either before calling -analyzeTimeRange:error: or from within one of the already associated request's completion handlers.

[@note] The VNRequest must have completion handler set otherwise no results can be returned.

Parameters:

request - The VNRequest to be added to the processing pipeline. If added from within a completionHandler, it will be processed on the same frame that is currently being processed.

processingOptions - The options applied to the request's processing of the video.

error - Returns an error that happened during scheduling of the requests. Check individual requests results and errors for their respective success and failures. This parameter is optional.

Returns:

Returns true if the request added to the processing pipeline.

addRequestWithProcessingOptionsError

public boolean addRequestWithProcessingOptionsError(VNRequest request,
                                                    NSDictionary<java.lang.String,?> processingOptions,
                                                    org.moe.natj.general.ptr.Ptr<NSError> error)

alloc

public static VNVideoProcessor alloc()

allocWithZone

public static VNVideoProcessor allocWithZone(org.moe.natj.general.ptr.VoidPtr zone)

analyzeTimeRangeError

public boolean analyzeTimeRangeError(CMTimeRange timeRange,
                                     org.moe.natj.general.ptr.Ptr<NSError> error)

Processes the video over the specified time range.

This call is synchronous and only returns after the video is processed through its duration or an error prevented the processing.

[@note] The intersection of the CMTimeRangeMake(start, duration) and CMTimeRangeMake(kCMTimeZero, asset.duration) will determine the timerange of the video to process

Parameters:

timeRange - Start and duration of the timerange within video to process. If the duration is longer than the video (e.g., kCMTimeIndefinite) the processing stops at the end of the video.

error - Returns an error that happened during the starting of the processing queue (for instance if the time range is not valid for the video asset). This parameter is optional.

Returns:

Returns true if all requests were scheduled and performed. Check individual requests results and errors for their respective success and failures.

analyzeWithTimeRangeError

public boolean analyzeWithTimeRangeError(CMTimeRange timeRange,
                                         org.moe.natj.general.ptr.Ptr<NSError> error)

public boolean removeRequestError(VNRequest request,
                                  org.moe.natj.general.ptr.Ptr<NSError> error)

Remove a VNRequest from the video processor, which means it won't be performed anymore.

This method can be called either before calling -analyzeTimeRange:error: or from within one of the already associated request's completion handlers.

Parameters:

request - The VNRequest to be removed from the processing pipeline.

error - Returns an error that happened during processing of the request, such as if the request was not found in the processing queue. This parameter is optional.

Returns:

Returns true if the request was found and removed from the processing pipeline.
