Ffmpeg trim video by time5/30/2023 ![]() To set these response headers, we will need a server. Doing this involves setting the popular COOP(cross-origin-opener-policy) and COEP(cross-origin-embedder-policy ) headers on our main document. Instead, they are isolated separately, each maintaining its unique browsing context. ![]() This state ensures that our website and cross-origin assets no longer share the same browsing context. To avoid this, any web page that needs access to these APIs needs to tell the browser explicitly it needs access to these special APIs, which will prompt the browser to put the web page in a special state known as cross-origin-isolated. ![]() ffmpeg.wasm uses this API to enable the web assembly threads spawn by its submodule to read and write to memory while performing its media manipulation.īy default, these web APIs are disabled for all web applications by most web browsers because they can be used maliciously by other cross-origin assets or windows in the same browsing context to perpetuate dangerous attacks. It is worth noting that the ffmpeg.wasm package uses some pretty new and Advanced web APIs, one of which is SharedArrayBuffer.
