Example 1 with DefaultAudioSink

use of com.google.android.exoplayer2.audio.DefaultAudioSink in project ExoPlayer by google.

the class LibflacAudioRenderer method supportsFormatInternal.

@Override

    Format outputFormat;
    if (format.initializationData.isEmpty()) {
        // The initialization data might not be set if the format was obtained from a manifest (e.g.
        // for DASH playbacks) rather than directly from the media. In this case we assume
        // ENCODING_PCM_16BIT. If the actual encoding is different then playback will still succeed as
        // long as the AudioSink supports it, which will always be true when using DefaultAudioSink.
        outputFormat = Util.getPcmFormat(C.ENCODING_PCM_16BIT, format.channelCount, format.sampleRate);
    } else {
        int streamMetadataOffset = STREAM_MARKER_SIZE + METADATA_BLOCK_HEADER_SIZE;
