C++ (Cpp) av_fifo_read Examples

Example #1

File: gxfenc.c Project: BackupTheBerlios/avidemux

static int gxf_new_audio_packet(GXFContext *gxf, GXFStreamContext *sc, AVPacket *pkt, int flush)
{
    int size = flush ? av_fifo_size(&sc->audio_buffer) : GXF_AUDIO_PACKET_SIZE;

    if (!size)
        return 0;
    av_new_packet(pkt, size);
    av_fifo_read(&sc->audio_buffer, pkt->data, size);
    pkt->stream_index = sc->index;
    pkt->dts = sc->current_dts;
    sc->current_dts += size / 2; /* we only support 16 bit pcm mono for now */
    return size;
}

Example #2

 * Resizes a FIFO.
