Method Detail

consume

public static void consume(long presentationTimeUs,
                           ParsableByteArray seiBuffer,
                           TrackOutput[] outputs)

Consumes the unescaped content of an SEI NAL unit, writing the content of any CEA-608 messages as samples to all of the provided outputs.

Parameters:

presentationTimeUs - The presentation time in microseconds for any samples.

seiBuffer - The unescaped SEI NAL unit data, excluding the NAL unit start code and type.

outputs - The outputs to which any samples should be written.

consumeCcData

public static void consumeCcData(long presentationTimeUs,
                                 ParsableByteArray ccDataBuffer,
                                 TrackOutput[] outputs)

Consumes caption data (cc_data), writing the content as samples to all of the provided outputs.

Parameters:

presentationTimeUs - The presentation time in microseconds for any samples.

ccDataBuffer - The buffer containing the caption data.

outputs - The outputs to which any samples should be written.
