Yes, I'd like a new AVSEEK_FLAG_FRAMENUM for containers supporting it
Not sure if this is much related to seeking:
I'd like containers to export the AVIndex feature usage and add pts to
AVIndexEntry, also a way to generate the full AVIndexEntry and have the
possibility to export it as file to be loaded later.
Also user needs to specify if he wants to seek by dts or pts and
therefore what timestamp value refers to.
