Example 1 with FlacStreamMetadata

use of com.google.android.exoplayer2.extractor.FlacStreamMetadata in project ExoPlayer by google.

the class FlacExtractor method outputFormat.

private static void outputFormat(FlacStreamMetadata streamMetadata, @Nullable Metadata metadata, TrackOutput output) {
    Format mediaFormat = new Format.Builder().setSampleMimeType(MimeTypes.AUDIO_RAW).setAverageBitrate(streamMetadata.getDecodedBitrate()).setPeakBitrate(streamMetadata.getDecodedBitrate()).setMaxInputSize(streamMetadata.getMaxDecodedFrameSize()).setChannelCount(streamMetadata.channels).setSampleRate(streamMetadata.sampleRate).setPcmEncoding(getPcmEncoding(streamMetadata.bitsPerSample)).setMetadata(metadata).build();

Example 2 with FlacStreamMetadata

use of com.google.android.exoplayer2.extractor.FlacStreamMetadata in project ExoPlayer by google.

        // 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.
