Member Function Documentation

◆ __init__() [1/2]

__init__ ( const  Buffer)

◆ __init__() [2/2]

__init__ ( const MovieVideoCursor::Buffer  )

◆ compareTimestamp()

int compareTimestamp ( const MovieVideoCursor::Buffer  other)

Used to sort different buffers to ensure they correspond to the same source frame, particularly important when synchronizing the different pages of a multi-page texture.

Returns 0 if the two buffers are of the same frame, <0 if this one comes earlier than the other one, and >0 if the other one comes earlier.

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getLength()

int getLength ( )

◆ getTimestamp()

double getTimestamp ( )

Returns the nearest timestamp value of this particular buffer.

Ideally, MovieVideoCursor::set_time() for this timestamp would return this buffer again. This need be defined only if compare_timestamp() is also defined.
