StreamPlaybackUtil_zlib mimics video stream.

Public Functions

~StreamPlaybackUtil_zlib () KZ_OVERRIDE

Destructor.

virtual bool doDecode (const string &in, vector< char > &out) KZ_OVERRIDE

Decode frame from buffer.

If output is pixel data, provide it to output buffer and return true. Depending on threading strategy, runs either on dedicated thread or within the main thread,

See

startDecoderThread()

Return

Return true if output buffer is to be used. Class asks Kanzi to re-render if true is returned and creates new framebuffer with data.

Parameters

  • in: Input buffer as raw string. Connect infra has no knowledge on the contents. May contain a full or partial frame.

  • out: Optional. If decoder provides pixels to be rendered, they need to be populated here. Decoder may use received input and pass a gpu handle to kanzi using getNextRenderBuffer instead.

Public Static Functions

Parameters

  • filename: uri of video file to load.
