The isConfigSupported()
static method of the VideoEncoder
interface checks if VideoEncoder
can be successfully configured with the given config.
VideoEncoder.isConfigSupported(config)
A Promise
that resolves with an object containing the following members:
supported
-
A boolean value which is true
if the given config is supported by the encoder.
config
-
A copy of the given config with all the fields recognized by the encoder.
The following example tests if the browser supports accelerated and un-accelerated versions of several video codecs.
const codecs = ["avc1.42001E", "vp8", "vp09.00.10.08", "av01.0.04M.08"];
const accelerations = ["prefer-hardware", "prefer-software"];
const configs = [];
for (const codec of codecs) {
for (const acceleration of accelerations) {
configs.push({
codec,
hardwareAcceleration: acceleration,
width: 1280,
height: 720,
bitrate: 2_000_000,
bitrateMode: "constant",
framerate: 30,
not_supported_field: 123,
});
}
}
for (const config of configs) {
const support = await VideoEncoder.isConfigSupported(config);
console.log(
`VideoEncoder's config ${JSON.stringify(support.config)} support: ${
support.supported
}`,
);
}
