<< Click to display table of contents >> GetListOfAvailableSampleRates Procedure

Fills AList with audio sample rates acceptable for the Codec.

Unit [VCL and LCL] MRVFFMpegLists;

Unit [FMX] fmxMRVFFMpegLists;

procedure GetListOfAvailableSampleRates(Codec: TRVAudioCodec;
  SampleFormat: TRVSampleFormat; AList : TStrings);

Sample rate is a number of audio samples played in 1 second.

This function works only if FFmpeg is available. Otherwise, it simply clears AList.

For most codecs, AList is filled basing on Codec parameter, SampleFormat parameter is ignored.

Only for Codec = rvacWAV, SampleFormat is used (because RVMedia chooses different WAV codec depending on sample format).

Each added item has a text equal to a text representation of a sample rate, and an object equal to a sample rate (an integer value type-casted to TObject).

Not all codecs provide a list of acceptable sample rates.

After calling this function, you can use AList to choose possible value of:

•AudioSampleRate property of TRVCamRecorder component;

•EncodeSampleRate property of TRVAudioPlayer component.
