[FFmpeg-devel] [PATCH] avformat: move priv_pts from AVStream to an internal struct

[James Almer]

It has no reason to be in a public header, even if defined as private.

To be honest, none of the fields below the "not part of the API" notice
have any reason to be in the public struct, but this one is particularly
pointless and ugly to have there as FFFrac is defined in internal.h
