The removeAsync() method of the {{domxref("SourceBuffer")}} interface starts the process of asynchronously removing from the SourceBuffer media segments found within a specific time range. A {{jsxref("Promise")}} is returned, which is fulfilled when the buffers in the specified time range have been removed.

This method can only be called when {{domxref("SourceBuffer.updating", "updating")}} is false. If that's not the case, call {{domxref("SourceBuffer.abort", "abort()")}} instead.

Syntax

js-nolint
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 {{jsxref("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.

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