// AVCCDecoderModule is a PlatformDecoderModule wrapper used to ensure that
// only AVCC format is fed to the underlying PlatformDecoderModule.
// The AVCCDecoderModule allows playback of content where the SPS NAL may not be
// provided in the init segment (e.g. AVC3 or Annex B)
// AVCCDecoderModule will monitor the input data, and will delay creation of the
// MediaDataDecoder until a SPS and PPS NALs have been extracted.
//
// AVCC-only decoder modules are AppleVideoDecoder and EMEH264Decoder.
