dm385支持音频编解码吗?



使用的软件包是ipnc rdk 3.9.1

这个软件包支持音频编解码吗?有没有相关的技术文档或资料?

  • 你好,

    支持G.711.

    www.ti.com/.../IPNC-RDK-CSK
    Codecs
    Royalty-free and production-ready H.264, MJPEG, MPEG4 (HP, SP), G.711, and others
  • 你好,我想再问一下音频编解码的问题,图像数据是通过link来传输的,音频的采集也在vpss端,那么音频是如何传递的呢?
    图像有特定的帧,而音频我只看到有下面的程序:
    encodedBufferSize =
    AUDIO_audioEncode(ALG_AUD_CODEC_G711, (short *) gAudOutBuf,
    (short *) gAudInBuf, numBytes);
    if (encodedBufferSize <= 0)
    {
    OSA_ERROR("Audio encode error !!\n");
    continue;
    }

    encFrameSize = encodedBufferSize;
    virtAddr = gAudOutBuf;

    stream_write(virtAddr,
    encFrameSize,
    AUDIO_FRAME,
    STREAM_AUDIO, timestamp, 0, stream_get_handle());


    这个stream_write是写入了哪个stream呢?
