Public Member Functions

 __init__ (VorbisAudio src, Istream stream)
 Reads the .wav header from the indicated stream. More...
 
 __init__ (const VorbisAudioCursor)
 
- Public Member Functions inherited from MovieAudioCursor
 __init__ (MovieAudio src)
 This constructor returns a null audio stream — a stream of total silence, at 8000 samples per second. More...
 
 __init__ (const MovieAudioCursor)
 
bool aborted ()
 If aborted is true, it means that the "ready" samples are not being replenished. More...
 
int audioChannels ()
 Returns the number of audio channels (ie, two for stereo, one for mono). More...
 
int audioRate ()
 Returns the audio sample rate. More...
 
bool canSeek ()
 Returns true if the movie can seek. More...
 
bool canSeekFast ()
 Returns true if seek operations are constant time. More...
 
MovieAudio getSource ()
 Returns the MovieAudio which this cursor references. More...
 
double length ()
 Returns the length of the movie. More...
 
str readSamples (int n)
 Read audio samples from the stream and returns them as a string. More...
 
 readSamples (int n, Datagram dg)
 Read audio samples from the stream into a Datagram. More...
 
int ready ()
 Returns the number of audio samples that are ready to read. More...
 
 seek (double offset)
 Skips to the specified offset within the file. More...
 
 skipSamples (int n)
 Skip audio samples from the stream. More...

object __reduce__ ()
 
object __reduce_persist__ (object pickler)
 
VectorUchar encodeToBamStream ()
 Converts the TypedWritable object into a single stream of data using a BamWriter, and returns that data as a bytes object. More...
 
bool encodeToBamStream (VectorUchar data, BamWriter writer)
 Converts the TypedWritable object into a single stream of data using a BamWriter, and stores that data in the indicated string. More...
 
 fillin (DatagramIterator scan, BamReader manager)
 This internal function is intended to be called by each class's make_from_bam() method to read in all of the relevant data from the BamFile for the new object. More...
 
UpdateSeq getBamModified ()
 Returns the current bam_modified counter. More...
 
 markBamModified ()
 Increments the bam_modified counter, so that this object will be invalidated and retransmitted on any open bam streams. More...

TypeHandle getType ()
 
int getTypeIndex ()
 Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. More...
 
bool isExactType (TypeHandle handle)
 Returns true if the current object is the indicated type exactly. More...
 
bool isOfType (TypeHandle handle)
 Returns true if the current object is or derives from the indicated type. More...
 
- Public Member Functions inherited from ReferenceCount
int getRefCount ()
 Returns the current reference count. More...
 
 ref ()
 Explicitly increments the reference count. More...
 
bool testRefCountIntegrity ()
 Does some easy checks to make sure that the reference count isn't completely bogus. More...
 
bool testRefCountNonzero ()
 Does some easy checks to make sure that the reference count isn't zero, or completely bogus. More...
