[Ffmpeg-devel] [PATCH] Clarify definition of r_frame_rate

[Fred Rothganger]

Greetings,

I am trying to fix some issues with the calculation of r_frame_rate in 
av_find_stream_info().  As a first step toward that, it would be helpful 
to clarify what r_frame_rate should be.  Attached is a patch that adds a 
rather wordy comment to AVStream.r_frame_rate.  It describes the 
semantics I have relied on for quite a while for seeking in mpeg files.  
(BTW, "~24fps" means "24000/1001 fps", but it didn't seem important to 
express that much detail.)
