此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

removeAsync()
方法在
SourceBuffer
interface starts the process of asynchronously removing from the
SourceBuffer
media segments found within a specific time range.
A
Promise
is returned, which is fulfilled when the buffers in the specified time range have been removed.
This method can only be called when
updating
is
false
. If that's not the case, call
abort()
代替。
removePromise = sourceBuffer.removeAsync(start, end);
start
A double representing the start of the time range, in seconds.
end
A double representing the end of the time range, in seconds.
A
Promise
whose fulfillment handler is executed once the buffers in the specified time range have been removed from the
SourceBuffer
.
This example establishes an asynchronous function,
emptySourceBuffer()
, which simply clears the contents of the specified
SourceBuffer
.
async function emptySourceBuffer(msBuffer) {
await msBuffer.removeAsync(0, Infinity).catch(function(e) {
handleException(e);
}
}
