Class VTDecodeFrameFlags

  • public final class VTDecodeFrameFlags
extends java.lang.Object
    [@enum] VTDecodeFrameFlags Directives for the decompression session and the video decoder, passed into decodeFlags parameter of VTDecompressionSessionDecodeFrame. [@constant] kVTDecodeFrame_EnableAsynchronousDecompression With the kVTDecodeFrame_EnableAsynchronousDecompression bit clear, the video decoder is compelled to emit every frame before it returns. With the bit set, the decoder may process frames asynchronously, but it is not compelled to do so. [@constant] kVTDecodeFrame_DoNotOutputFrame A hint to the decompression session and video decoder that a CVImageBuffer should not be emitted for this frame. NULL will be returned instead. [@constant] kVTDecodeFrame_1xRealTimePlayback A hint to the video decoder that it would be OK to use a low-power mode that can not decode faster than 1x realtime. [@constant] kVTDecodeFrame_EnableTemporalProcessing With the kVTDecodeFrame_EnableTemporalProcessing bit clear, the video decoder should emit every frame once that frame's decoding is done -- frames may not be delayed indefinitely. With the bit set, it is legal for the decoder to delay frames indefinitely -- at least until VTDecompressionSessionFinishDelayedFrames or VTDecompressionSessionInvalidate is called.
