Detailed Description

Decoding time to sample box (STTS) iterator used to iterate through the compressed table. This class also provides convenient functions to query total number of samples and the duration from start_sample to end_sample.

Member Function Documentation

AdvanceSample()

bool shaka::media::mp4::DecodingTimeIterator::AdvanceSample

(

)

Advance to the next sample.

Returns

true if not past the last sample, false otherwise.

Definition at line 28 of file decoding_time_iterator.cc.

Duration()

int64_t shaka::media::mp4::DecodingTimeIterator::Duration	(	uint32_t	start_sample,
		uint32_t	end_sample
	)		const

Returns

Duration from start_sample to end_sample, both 1-based, inclusive.

Definition at line 44 of file decoding_time_iterator.cc.

IsValid()

bool shaka::media::mp4::DecodingTimeIterator::IsValid

(

)

const

Returns

true if the iterator is still valid, false if past the last sample.

Definition at line 39 of file decoding_time_iterator.cc.

NumSamples()

uint32_t shaka::media::mp4::DecodingTimeIterator::NumSamples

(

)

const

Returns

Total number of samples in the table.

Definition at line 65 of file decoding_time_iterator.cc.

sample_delta()

uint32_t shaka::media::mp4::DecodingTimeIterator::sample_delta ( ) const

inline

Returns

Sample delta for current sample.
