public FramerateConverter(MediaType inputMediaType, MediaType outputMediaType)

Parameters

inputMediaType MediaType

The input media type describing the source video format and framerate.

Methods

Dispose()

Releases all resources used by the framerate converter.

public void Dispose()

Read()

Reads the next converted output frame from the converter.

public VersatileBuffer Read()

Returns

VersatileBuffer

The converted video frame with adjusted timestamp, or null if no frame is available.

Write(VersatileBuffer)

Writes an input video frame to the converter for framerate conversion.

public void Write(VersatileBuffer packet)

Parameters

packet VersatileBuffer

The input video frame to process.

Remarks

The frame may be dropped if it arrives too early relative to the expected output timing. Discontinuities in the input stream are automatically detected and handled.
