[SMK] Seek error

Description

The attached SMK file causes a seek error which is easily reproducible with ffplay (and probably ffmpeg since it affects other ffmpeg lib based tools).

IVYDES.SMK: error while seeking

I tried the file with RAD Video Tools without seeing anything strange but I don't know this format at all.

Is this also reproducible with ffmpeg (the application)? Please only report ffplay issues if they are not reproducible with ffmpeg.

comment:2 Changed 5 years ago by Underground78

I don't know how to try reproducing this issue with ffmpeg otherwise I would have reported with it.

comment:3 Changed 5 years ago by cehoyos

Did you try the following?

$ ffmpeg -ss 1 -i IVYDES.SMK -qscale 2 out.avi

comment:4 Changed 5 years ago by Underground78

It does fail with IVYDES.SMK: could not seek to position 1.000.
