CBaseControlVideo.get_BitRate method

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The get_BitRate method retrieves an approximate bit rate for the video.

Syntax

HRESULT get_BitRate(
   long *pBitRate
);

Parameters

pBitRate

Pointer to the bit rate, in bits per second.

Return value

Returns NOERROR if successful or E_OUTOFMEMORY if not enough memory is available.

Remarks

This member function implements the IBasicVideo::get_BitRate method. It calls the pure virtual CBaseControlVideo::GetVideoFormat to retrieve the VIDEOINFOHEADER structure from the derived class.

Requirements

Ctlutil.h (include Streams.h)
