Description
When using the drawtext=timecode filter, if the source video changes bit depths it resets the timecode counter at the original value
This is similar to the issue of https://trac.ffmpeg.org/ticket/4400 but on the latest ffmpeg it only affects the drawtext, not the rest of the video
How to reproduce:
% ffmpeg.exe -v 9 -loglevel 99 -i D:\cartest_supers.mov -filter_complex "drawtext=timecode='00\:00\:00\:00':r=23.976:x=0:y=0:fontfile=\'C:\\cli\\misc\\arial.ttf\':fontsize=96:fontcolor=black" -pix_fmt yuv420p -vcodec libx264 -crf 24 -an D:\outvid.mp4 ffmpeg version N-76347-gdd36749 built on 2015-10-28
