Comment (by kgp700):

 I did additional tests
 It's not relate rtmp or live streaming
 so, I changed title

 I don't know in detail, rfps(void ff_rfps_calculate(AVFormatContext *ic))
 is measure real framerate feature?

 I compared Old version ffmpeg and recently version log.
 The difference is get framerate information by rfps or not

 I think rfps is not good feature for DirectShow filters (especially for
 kind of screen capture filters)

 Can not disable rfps feature when input DirectShow filters?
