convert_frames(frames: AudioFrames | VideoFrames | ImageFrames | list[AudioFrames] | list[VideoFrames] | list[ImageFrames], storage: CPUStorage | None = None, **kwargs) → CPUBuffer

Convert the decoded frames to buffer.

Parameters:

• frames – Frames objects.

• storage (spdl.io.CPUStorage) – Storage object. See spdl.io.cpu_storage().

Returns:

A Buffer object.

The shape of the buffer object is

• AudioFrames -> [C, H] or [N, C].

• VideoFrames -> [N, C, H, W] or [N, H, W, C].

• ImageFrames -> [C, H, W].

• list[AudioFrames] -> [B, C, H] or [B, N, C].

• list[VideoFrames] -> [B, N, C, H, W] or [B, N, H, W, C].

• list[ImageFrames] -> [B, C, H, W].

where

• B: batch

• C: channel (color channel or audio channel)

• N: frames

• W: width

• H: height
