Member Function Documentation

decode() [1/2]

std::uint8_t * gnash::media::gst::AudioDecoderGst::decode ( const std::uint8_t *  input, std::uint32_t  inputSize, std::uint32_t &  outputSize, std::uint32_t &  decodedData  )

virtual

Decodes a frame and returns a pointer to the data.

Parameters

input	The audio data
inputSize	The size of the video data
outputSize	The output size of the video data, is passed by reference.
decodedData	The amount of bytes that has been decoded when decoding is done, is passed by reference.

Returns

a pointer to the decoded data, or NULL if decoding fails. The caller owns the decoded data, which was allocated with new [].

Todo:

return a SimpleBuffer by unique_ptr

Reimplemented from gnash::media::AudioDecoder.

decode() [2/2]

std::uint8_t * gnash::media::gst::AudioDecoderGst::decode ( const EncodedAudioFrame &  input, std::uint32_t &  outputSize  )

virtual

Decodes an EncodedAudioFrame and returns a pointer to the decoded data.

Parameters

input	The audio data
outputSize	The output size of the video data, is passed by reference.

Returns

a pointer to the decoded data, or NULL if decoding fails. The caller owns the decoded data, which was allocated with new [].

Todo:

return a SimpleBuffer by unique_ptr

Reimplemented from gnash::media::AudioDecoder.

References _, gnash::media::gst::EncodedExtraGstData::buffer, gnash::media::EncodedAudioFrame::data, gnash::media::EncodedAudioFrame::dataSize, gnash::media::EncodedAudioFrame::extradata, gnash::log_error(), and swfdec_gst_decoder_push().
