Returns value or error.


Frame rate of a video media type, in frames per second.
Requires a media item being loaded into the player.

The frame rate is expressed as a ratio. The upper 32 bits of the attribute value contain the numerator and the lower 32 bits contain the denominator. For example, if the frame rate is 30 frames per second (fps), the ratio is 30/1. If the frame rate is 29.97 fps, the ratio is 30,000/1001.


Query it:

Set Variable [ $num; Value: MBS("WMFP.GetVideoFrameRate"; $$player) ]
Set Variable [ $t; Value: MBS( "Math.BitwiseShiftRight"; $num; 32) ]
Set Variable [ $b; Value: MBS( "Math.BitwiseAND"; $num; 4294967295)]
Set Variable [ $value; Value: $t / $b ]

Example result: 29.97
