C++ (Cpp) dump_metadata_item Examples

Example #1

File: tizgmusicgraphops.cpp Project: tizonia/tizonia-openmax-il

void graph::gmusicops::do_retrieve_metadata ()
{
  OMX_U32 index = 0;
  const int gmusic_index = 0;
  // Extract metadata from the gmusic source
  while (OMX_ErrorNone == dump_metadata_item (index++, gmusic_index))
  {
  };

  // Now extract metadata from the decoder
  const int decoder_index = 1;
  index = 0;
  const bool use_first_as_heading = false;
  while (OMX_ErrorNone
         == dump_metadata_item (index++, decoder_index, use_first_as_heading))
  {
  };

  OMX_GetParameter (handles_[2], OMX_IndexParamAudioPcm, &renderer_pcmtype_);

  // Now print renderer metadata
  TIZ_PRINTF_MAG (
      "     %ld Ch, %g KHz, %lu:%s:%s \n", renderer_pcmtype_.nChannels,
      ((float)renderer_pcmtype_.nSamplingRate) / 1000,
