Member Function Documentation
◆ ComputeSize()
| size_t shaka::media::BaseDescriptor::ComputeSize | ( | ) |
Compute the size of this descriptor. It will also update descriptor size.
- Returns
- The size of result descriptor including child descriptors.
Definition at line 110 of file es_descriptor.cc.
◆ data_size()
|
inlineprotected |
- Returns
- descriptor data size without header in bytes.
Definition at line 69 of file es_descriptor.h.
◆ Parse()
| bool shaka::media::BaseDescriptor::Parse | ( | const std::vector< uint8_t > & | data | ) |
Parse the descriptor from input data.
- Parameters
-
data contains the descriptor data.
Definition at line 83 of file es_descriptor.cc.
◆ Read()
| bool shaka::media::BaseDescriptor::Read | ( | BitReader * | reader | ) |
Read the descriptor.
- Parameters
-
reader points to a BitReader object.
Definition at line 88 of file es_descriptor.cc.
◆ Write()
| void shaka::media::BaseDescriptor::Write | ( | BufferWriter * | writer | ) |
Write the descriptor to buffer. This function calls ComputeSize internally to compute and update descriptor size.
- Parameters
-
writer points to a BufferWriter object which wraps the buffer for writing.
