using av_seek_frame(..., AVSEEK_FLAG_ANY | AVSEEK_FLAG_BYTE)) then the
following packets from av_read_frame have the dts field reset starting from
0 again. That behavior is only observed when using AVSEEK_FLAG_BYTE, which
I really need in this case. This is problematic, because I have been using
the packet dts field to compute the current time of the frame in the video.

What kind of video format are you reading? In most cases, the packet number
and display time cannot be read from the file or stream,  but only
calculated by straightforward counting.
