VideoFramesPtr spdl::core::create_reference_video_frame(const std::string &sample_fmt, const void *data, int bits, const std::vector<size_t> &shape, const std::vector<int64_t> &stride, Rational frame_rate, int64_t pts)

Create a video frame referencing external data.

Creates a frame that references externally managed memory without copying. The caller must ensure the data remains valid for the lifetime of the frame.

Parameters:

  • sample_fmt – Pixel format string (e.g., “rgb24”, “yuv420p”).

  • data – Pointer to external video data.

  • bits – Bits per component.

  • shape – Shape vector [height, width, …].

  • stride – Stride vector for each dimension.

  • frame_rate – Frame rate as a rational number.

  • pts – Presentation timestamp.

Returns:

Video frames referencing the external data.
