SourceBuffer: appendBufferAsync() method
Note: This feature is available in Dedicated Web Workers.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The appendBufferAsync() method
of the SourceBuffer interface begins the process of asynchronously
appending media segment data from an ArrayBuffer,
a TypedArray or a DataView object to the SourceBuffer object.
It returns a Promise which is fulfilled once the buffer has been appended.
Syntax
appendBufferAsync(source)
Parameters
source-
Either an
ArrayBuffer, aTypedArrayor aDataViewobject that contains the media segment data you want to add to theSourceBuffer.
Return value
A Promise which is fulfilled when the buffer has been added successfully to the SourceBuffer object,
or null, if the request could not be initiated.
Examples
This simplified example async function, fillSourceBuffer(), takes as input
parameters buffer, an ArrayBuffer, a TypedArray, or a DataView, and a
SourceBuffer object to which to append the source media from the buffer.
async function fillSourceBuffer(buffer, msBuffer) {
try {
while (true) {
await msBuffer.appendBufferAsync(buffer);
}
} catch (e) {
handleException(e);
}
}
