Description

When using -dcodec copy to copy a timecode track from an input Quicktime to an output Quicktime, I get a "Floating point exception" error and the unresulting file is unplayable.

Still reproducible with

ffmpeg -i fcp_export8.mov -dcodec copy -map 0:2 -an -vn out.mov

  • Keywords crash fpe added

comment:4 Changed 6 years ago by reimar

No longer crashes, but I don't think it will work as expected.

comment:5 Changed 6 years ago by dericed

True, no crash, but the resulting quicktime is invalid.

This used to be fixed (in 0.11 and 1.0), now reproducible again, I opened ticket #2045 for the regression.
