Pause, resume and abort conversion

Pause and resume
tsx
import {webcodecsController, convertMedia} from'@remotion/webcodecs';
constcontroller=webcodecsController();
convertMedia({
 src: 'https://www.w3schools.com/html/mov_bbb.mp4',
 container: 'webm',
 controller,
})
 .then(() => {
 console.log('Finished downloading');
 })
 .catch((err) => {
 console.error('Error downloading', err);
 });
// Wait 1 sec, pause, wait 1 sec, resume
awaitnewPromise((resolve) =>setTimeout(resolve, 1000));
controller.pause();
awaitnewPromise((resolve) =>setTimeout(resolve, 1000));
controller.resume();

Cancel a conversion process
tsx
import {webcodecsController, convertMedia} from'@remotion/webcodecs';
constcontroller=webcodecsController();
convertMedia({
 src: 'https://www.w3schools.com/html/mov_bbb.mp4',
 container: 'webm',
 controller,
})
 .then(() => {
 console.log('Finished parsing');
 })
 .catch((err) => {
 console.error('Error parsing', err);
 });
// Cancel after 10 seconds
awaitnewPromise((resolve) =>setTimeout(resolve, 10_000));
controller.abort();

Checking if a conversion was aborted
tsx
import {hasBeenAborted} from'@remotion/media-parser';
import {webcodecsController, convertMedia} from'@remotion/webcodecs';
constcontroller=webcodecsController();
constpromise=convertMedia({
 src: 'https://www.w3schools.com/html/mov_bbb.mp4',
 container: 'webm',
 controller,
})
 .then(() => {
 console.log('Finished conversion');
 })
 .catch((err) => {
if (hasBeenAborted(err)) {
 console.log('Conversion was cancelled');
 } else {
 console.error('Error converting', err);
 }
 });
