Detailed Description
Decoded YUV frame in a non-planar format (thus "NP")
For example, the YUYV422 format (AV_PIX_FMT_YUYV422), where the data layout looks like this: YUYV YUYV YUYV YUYV YUYV YUYV
here we could optimize and copy from YUYV422 directly to YUV420 on the GPU like in YUVFrame::fromAVBitmapFrame maybe someday ..
class AVBitmapFrameNP : public AVMediaFrame {
public: AVBitmapFrameNP(); ///< Default ctor virtual ~AVBitmapFrameNP(); ///< Default virtual dtor frame_essentials(FrameClass::avbitmap_np, AVBitmapFrameNP); frame_clone(FrameClass::avbitmap_np, AVBitmapFrameNP); // TODO: think about this!
public: // redefined virtual virtual std::string dumpPayload(); virtual void print(std::ostream& os) const; ///< How to print this frame to output stream virtual void reset(); ///< Reset the internal data virtual void update(); ///< Uses AVBitmapFrame::av_frame width and height and AVBitmapFrame::av_pixel_format to calculate AVBitmapFrame::bmpars
public: // helper objects AVPixelFormat av_pixel_format; ///< From AVCodecContext .. this class implies YUV422P so this is not really required .. BitmapPars bmpars; ///< Reference parameters for corresponding YUV420P frame uint8_t* payload; ///< shortcut to the non-planar data }; Decoded RGB frame in FFMpeg format
- This FrameClass is produced by SwScaleFrameFilter (that performs YUV=>RGB interpolation). This FrameClass is used typically when passing frame data to shared memory
- Constructor does not reserve data for frames. This is done by classes using this class (see SwScaleFrameFilter)
- Frames of this class can also be pre-reserved after construction, by using the member AVRGBFrame::reserve
Copiable/Queable : yes
The documentation for this class was generated from the following files:
