Android Capabilities

Android devices vary a lot in what their hardware codecs can do — maximum resolution, number of simultaneous decoder instances, supported encoder configurations. Two Android-only helpers let you adapt before decoding or exporting. Both throw if called on iOS (where AVFoundation negotiates configurations by itself).

getDecodingCapabilitiesFor

import { getDecodingCapabilitiesFor } from '@azzapp/react-native-skia-video';

const capabilities = getDecodingCapabilitiesFor('video/avc');
// { maxInstances: 16, maxWidth: 3840, maxHeight: 2176 } | null

Returns the decoding limits for a mime type (most of the time you'll check video/avc):

Field	Description
maxInstances	How many decoders can run at once — caps how many video items can overlap in a composition.
maxWidth / maxHeight	Maximum decodable frame size — cap your items' resolution accordingly.

getValidEncoderConfigurations

import { getValidEncoderConfigurations } from '@azzapp/react-native-skia-video';

const configs = getValidEncoderConfigurations(1080, 1920, 60, 10_000_000);
const best = configs?.[0];

await exportVideoComposition({
  // …
  width: best.width,
  height: best.height,
  frameRate: best.frameRate,
  bitRate: best.bitRate,
  encoderName: best.encoderName,
});

Given your target export settings, returns the closest configurations the device's encoders actually support — lowering resolution, frame rate or bit rate if needed while keeping the aspect ratio. Each entry contains:

Field	Description
encoderName	Pass it to exportVideoComposition to pin this encoder.
hardwareAccelerated	Prefer entries where this is true.
width / height / frameRate / bitRate	The adjusted, supported values.
