SourceBuffer: removeAsync() 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 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((e) => {
    handleException(e);
  });
}

Specifications

This feature is not part of any specification. It is not on track to become a standard.
