Do not specify export flags for protected system broadcasts.

Protected system broadcasts should not specify the export flag.
Marking them as NOT_EXPORTED breaks sticky broadcasts in some
cases.

 # Release notes
 
+### Unreleased changes
+
+* Core library:
+    * Add suppression reason for unsuitable audio route and play when ready
+        change reason for suppressed too long.
+        ([#15](https://github.com/androidx/media/issues/15)).
+    * Make the maximum difference of the start time of two segments to be
+        merged configurable in `SegmentDownloader` and subclasses
+        ([#248](https://github.com/androidx/media/pull/248)).
+    * Add `ExoPlayer.setVideoEffects()` for using `Effect` during video
+        playback.
+    * Update `SampleQueue` to store `sourceId` as a `long` rather than an
+        `int`. This changes the signatures of public methods
+        `SampleQueue.sourceId` and `SampleQueue.peekSourceId`.
+    * Fix network type detection on API 33
+        ([#10970](https://github.com/google/ExoPlayer/issues/10970)).
+    * Make the maximum difference of the start time of two segments to be
+          merged configurable in `SegmentDownloader` and subclasses
+          ([#248](https://github.com/androidx/media/pull/248)).
+* Extractors:
+    *   Fix `NullPointerException` when calling `ExoPlayer.isTunnelingEnabled`
+        ([#10977](https://github.com/google/ExoPlayer/issues/10977)).
+* Audio:
+    *   Fix bug where some playbacks fail when tunneling is enabled and
+        `AudioProcessors` are active, e.g. for gapless trimming
+        ([#10847](https://github.com/google/ExoPlayer/issues/10847)).
+    *   Encapsulate Opus frames in Ogg packets in direct playbacks (offload).
+* Video:
+    *   Map HEVC HDR10 format to `HEVCProfileMain10HDR10` instead of
+        `HEVCProfileMain10`.
+* DASH:
+    *   Add full parsing for image adaptation sets, including tile counts
+        ([#3752](https://github.com/google/ExoPlayer/issues/3752)).
+* RTSP:
+    *   Catch the IllegalArgumentException thrown in parsing of invalid RTSP
+        Describe response messages
+        ([#10971](https://github.com/google/ExoPlayer/issues/10971)).
+* Session:
+    * Fix a bug where notification play/pause button doesn't update with
+        player state ([#192](https://github.com/androidx/media/issues/192)).
+    *  Fix a bug where notification play/pause button doesn't update with
+           player state ([#192](https://github.com/androidx/media/issues/192)).
+*   RTSP:
+    *   Catch the IllegalArgumentException thrown in parsing of invalid RTSP
+        Describe response messages
+        ([#10971](https://github.com/google/ExoPlayer/issues/10971)).
+*   Metadata:
+    *   Parse multiple null-separated values from ID3 frames, as permitted by
+        ID3 v2.4.
+    *   Add `MediaMetadata.mediaType` to denote the type of content or the type
+        of folder described by the metadata.
+    *   Add `MediaMetadata.isBrowsable` as a replacement for
+        `MediaMetadata.folderType`. The folder type will be deprecated in the
+        next release.  
+* Transformer:
+    *   Remove `Transformer.Builder.setMediaSourceFactory(MediaSource.Factory)`.
+        Use `ExoPlayerAssetLoader.Factory(MediaSource.Factory)` and
+        `Transformer.Builder.setAssetLoaderFactory(AssetLoader.Factory)`
+        instead.
+    *   Remove `Transformer.startTransformation(MediaItem,
+        ParcelFileDescriptor)`.
+* Remove deprecated symbols:
+    *   Remove `DefaultAudioSink` constructors, use `DefaultAudioSink.Builder`
+        instead.
