Android offline download ignores OfflineDownloadRequest.minimumBitrate

Bug: Android offline download ignores OfflineDownloadRequest.minimumBitrate (regression)

Summary

On Android, offline downloads started via OfflineContentManager.download({ minimumBitrate }) do not respect the selected bitrate/quality. This worked in an earlier bitmovin-player-react-native version but appears broken after upgrading.

What we expect

When passing minimumBitrate (in bps) the SDK should select the nearest higher available video representation (per the RN type docs) and download that rendition (or at least not exceed the chosen quality).

What actually happens

On Android, the downloaded offline content appears to be:

• always the highest available bitrate, OR
• not constrained by minimumBitrate at all (quality/size indicates a higher representation than selected), OR
• inconsistent between devices

iOS behavior: works

Reproduction

Steps

1. Use an HLS or DASH stream with multiple video bitrates (e.g., 360p/480p/720p/1080p).
2. Fetch available bitrates from the manifest (we parse bandwidth/averageBandwidth).
3. Start offline download with a chosen bitrate:
   • Example chosen: 360p ~ 800000 bps
4. Wait for download completion.
5. Inspect the resulting offline content (file size / downloaded representation) and compare with the selected bitrate.

Code snippet (minimal)

ts

import {
OfflineContentManager,
OfflineState,
SourceType,
OfflineDownloadRequest,
} from 'bitmovin-player-react-native';
const manager = new OfflineContentManager({
identifier: '<some-stable-id>',
sourceConfig: {
url: '<manifest-url>',
type: SourceType.HLS, // or DASH
// drmConfig: { widevine: { licenseUrl: '<license-url>' } } // if DRM
},
});
await manager.initialize();
const remove = manager.addListener({
onOptionsAvailable: (e) => {
if (e.state !== OfflineState.NotDownloaded) return;
const downloadRequest: OfflineDownloadRequest = {
minimumBitrate: bitrate!, // bps
audioOptionIds: e.options?.audioOptions?.map((a) => a.id) ?? [],
textOptionIds: e.options?.textOptions?.map((t) => t.id) ?? [],
};
manager.download(downloadRequest);
},
});
await manager.getOptions();

Question

Is there any change in Android offline track selection behavior for minimumBitrate in recent versions, or a new/required setting (e.g., max bitrate, preferred track selection, etc.) to enforce bitrate constraints for offline downloads?
