 ./ffmpeg  -i ~/tickets/4914/xdcam8mp2-1s_small.ts -c:v copy out.mxf
fails, no output anymore

./ffmpeg -i matrixbench_mpeg2.mpg -c:v copy -t 1 test.avi
the output now has 600fps

./ffmpeg -i ~/tickets/236/fcp_export8.mov -codec copy -map 0 out.mov
something goes terribly wrong with the timecode tracks
"fps 2997 is too large"

If you want more cases that this breaks, it should be easy to find
i think fate does not test stream copy very well
