Class: AesFileReadableStream

AesFileReadableStream()

ReadableStream wrapper for seeking and reading an encrypted AesFile. This class provides a seekable source with parallel streams and cached buffers for performance.

Constructor

new AesFileReadableStream()

Construct a wrapper do not use directly, use createFileReadableStream() instead.

AesFileReadableStream

Methods

(async) cancel(reasonopt)

Cancel the stream
Parameters:
Name Type Attributes Description
reason any <optional>
 The reason
Source:

(async) fillBuffer(cacheBuffer, startPosition, length)

Fills a cache buffer with the decrypted data from the encrypted source file.
Parameters:
Name Type Description
cacheBuffer Buffer The cache buffer that will store the decrypted contents
startPosition number The start position
length number The length of the data requested
Source:

getWorkerPath() → {string}

Get the worker path used for parallel streaming
Source:
Returns:
The worker path
Type
string

setWorkerPath(path)

Set the worker path
Parameters:
Name Type Description
path string The worker path
Source:

(static) createFileReadableStream(aesFile, buffersCount, bufferSize, threads, backOffset)

Creates a seekable stream from an encrypted file source
Parameters:
Name Type Default Description
aesFile AesFile The source file.
buffersCount number 1 Number of buffers to use.
bufferSize Uint8Array 524288 The length of each buffer.
threads number 1 The number of threads/streams to read the file in parallel.
backOffset number 32768 The backwards offset. Some media libraries might request data rewinding the stream just a few bytes backwards. This ensures those bytes are included so we don't reset the stream.
