I'm using ffprobe to get timecode from an mxf which has DF timecode but with a non DF frame rate. I'm getting the error Drop frame is only allowed with 30000/1001 or 60000/1001 FPS.
I'm running ffprobe -i "IMX 10bit.mxf" -print_format json -show_streams -show_format and getting the following:

-show_formatas well.ffmpegcode base and it seems that timecode has its own frame rate specified...maybe this file was converted from an 29.97 to 25 without converting the timecode framerate?
