// In the JVT syntax, frequently flags are used that indicate the presence of
|
||
|
|
// certain pieces of information in the NALU. Here, these flags are also
|
||
|
|
// present. In the encoder, those bits indicate that the values signaled to
|
||
|
|
// be present are meaningful and that this part of the syntax should be
|
||
|
|
// written to the NALU. In the decoder, the flag indicates that information
|
||
|
|
// was received from the decoded NALU and should be used henceforth.
|
||
|
|
// The structure names were chosen as indicated in the JVT syntax
