[FFmpeg-devel] Suggested Patch for timecode timebase calculation in mov.c

I never heard back about this and I think I have a new better solution 
now. I don't think the current mov.c timecode processing is handling the 
case where the timecode is in counter mode. Please read the following 
page 190 from:



"Number of frames
An 8-bit integer that contains the number of frames per second for the 
timecode format. If the time is a counter, this is the number of frames 
for each counter tick."

I have sample media in counter mode if it helps. I tried to send that 
before as well, but I think it was too large. Please let me know how 
else I can help with this enhancement. Feel free to send clarification 
questions to me.
