Examples with FLVHeader org.red5.io.flv.FLVHeader used on opensource projects

Example 1 with FLVHeader

use of org.red5.io.flv.FLVHeader in project red5-io by Red5.

the class FLVReader method decodeHeader.

/**
 * {@inheritDoc}
 */
@Override
public void decodeHeader() {
    // flv header is 9 bytes
    fillBuffer(9);
    header = new FLVHeader();
    // skip signature
    in.skip(4);
    header.setTypeFlags(in.get());
    header.setDataOffset(in.getInt());
    if (log.isDebugEnabled()) {
        log.debug("Header: {}", header.toString());
    }
}

Example 2 with FLVHeader

use of org.red5.io.flv.FLVHeader in project red5-io by Red5.

the class FLVWriter method writeHeader.

/**
 * Writes the header bytes
 *
 * @throws IOException
 *             Any I/O exception
 */
@Override
public void writeHeader() throws IOException {
    // create a buffer
    // FLVHeader (9 bytes) + PreviousTagSize0 (4 bytes)
    ByteBuffer buf = ByteBuffer.allocate(HEADER_LENGTH + 4);
    // instance an flv header
    FLVHeader flvHeader = new FLVHeader();
    flvHeader.setFlagAudio(audioCodecId != -1 ? true : false);
    flvHeader.setFlagVideo(videoCodecId != -1 ? true : false);
    // write the flv header in the buffer
    flvHeader.write(buf);
    // the final version of the file will go here
    createOutputFile();
    // write header to output channel
    bytesWritten = fileChannel.write(buf);
    assert ((HEADER_LENGTH + 4) - bytesWritten == 0);
    log.debug("Header size: {} bytes written: {}", (HEADER_LENGTH + 4), bytesWritten);
    buf.clear();
    buf = null;
