SourceBuffer.removeAsync()

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 removeAsync() method of the 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() instead.

Syntax

removeAsync(start, end)

Parameters

start

A double representing the start of the time range, in seconds.

end

A double representing the end of the time range, in seconds.

Return value

A Promise whose fulfillment handler is executed once the buffers in the specified time range have been removed from the SourceBuffer.

Examples

This example establishes an asynchronous function, emptySourceBuffer(), which clears the contents of the specified SourceBuffer.

async function emptySourceBuffer(msBuffer) {
  await msBuffer.removeAsync(0, Infinity).catch(function(e) {
    handleException(e);
  }
}
