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-608/708 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.
