Functions
Type | Name | Description | |
---|---|---|---|
![]() |
void | AddDecoder
(
ICompressedAudioInfo* CompressedAudioInfo |
Adds the decoder to the streaming manager to prevent stream chunks from getting reaped from underneath it |
![]() |
void | AddReferenceToChunk
(
const FAudioChunkHandle& InHandle |
This can be used to increment reference counted handles to audio chunks. |
![]() |
void | AddStreamingSoundSource
(
FSoundSource* SoundSource |
Adds a new Sound Source to the streaming manager. |
![]() |
void | AddStreamingSoundWave
(
const FSoundWaveProxyPtr& SoundWave |
Adds a new Sound Wave to the streaming manager. |
![]() ![]() |
FAudioChunkHandle | BuildChunkHandle
(
const uint8* InData, |
This can be called by implementers of IAudioStreamingManager to construct an FAudioChunkHandle using an otherwise inaccessible constructor. |
![]() ![]() |
bool | CanCreateSoundSource
(
const FWaveInstance* WaveInstance |
|
![]() |
FString | Generate a memory report as a formatted string for this streaming manager. | |
![]() ![]() |
FAudioChunkHandle | GetLoadedChunk
(
const FSoundWaveProxyPtr& SoundWave, |
Gets a pointer to a chunk of audio data |
![]() ![]() |
bool | IsManagedStreamingSoundSource
(

![]() |
uint64 | TrimMemory
(
uint64 NumBytesToFree |
This will start evicting elements from the cache until either hit our target of bytes or run out of chunks we can free. |
