1251,AVSEEK_FLAG_ANY fails with attached file,DonMoir,,"I have a normal seek which seeks to a timestamp (not using AVSEEK_FLAG_ANY) and does some additional checking and works for all files tested.

I specialize a seek back to the start of the file as this should not require as much checking. In this case I use AVSEEK_FLAG_ANY as it's essentially a 'don't care' and just get me back to the start of the file.

This has always worked, but using AVSEEK_FLAG_ANY fails to seek with the attached avseek_flag_any_fails.mp4 file. The return value from avformat_seek_file is zero but really it hasn't done anything.

The other files I have including all other mp4 files work fine. If I don't use AVSEEK_FLAG_ANY then I have to deal with files that may not have a first keyframe and the seek will fail on those files.

Because of this file I am back to doing extra checking to make sure I can seek back to start but should not have to.

Can't point you to a failing case with any of the common tools because I don't think any of them use AVSEEK_FLAG_ANY.

Here's the stats on my build:
