Examples with PMTStream org.jcodec.containers.mps.psi.PMTSection.PMTStream used on opensource projects

Example 1 with PMTStream

use of org.jcodec.containers.mps.psi.PMTSection.PMTStream in project ddf by codice.

the class MpegTransportStreamMetadataExtractor method getProgramMapTable.

private void getProgramMapTable(final MTSPacket packet) {
    final ByteBuffer payload = packet.getPayload();
    final int pointer = payload.get() & 0xff;
    payload.position(payload.position() + pointer);
    final int packetId = packet.getPid();
    final PMTSection pmt = PMTSection.parsePMT(payload);
    programMapTables.put(packetId, pmt);
    for (final PMTStream stream : pmt.getStreams()) {
        programElementaryStreams.put(stream.getPid(), stream);
    }
}

Example 2 with PMTStream

use of org.jcodec.containers.mps.psi.PMTSection.PMTStream in project ddf by codice.
