SourceBuffer.appendBufferAsync()
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
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
or
ArrayBufferView
object to the SourceBuffer
. It
returns a Promise
which is fulfilled once the buffer has been appended.
Syntax
appendPromise = sourceBuffer.appendBufferAsync(source);
Parameters
source
-
A
BufferSource
(that is, either anArrayBufferView
orArrayBuffer
) which 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
, or null
if the request could not be
initiated.
Example
This simplified example async function, fillSourceBuffer()
, takes as input
parameters BufferSource
, buffer
, and a
SourceBuffer
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);
}
}
