Bug in UMC::AudioFrameConstructor

jere_jones1 — Thu, 24 Mar 2011 06:54:16 GMT

There is a bug in the AudioFrameConstructor that causes a failure in BufferedAudioFrameConstructor after repositioning the demuxer.

In the audio-video-codec samples, AudioFrameConstructor has a member variable (m_bHeaderParsed) that is set to false during Init().

When repositioning the demuxer, Reset() is called on all the frame constructors. However, because AudioFrameConstructor does not override Reset(), m_bHeaderParsed is not set back to false. If it was true prior to the repositioning, BufferedAudioFrameConstructor will never be able to retrieve another frame.

The fix is simple: Override Reset() in AudioFrameConstructor. In it, call the base Reset() and set m_bHeaderParsed = false.

Kind Regards,
Jere
