[Libav-user] Seeking MPEG-DASH video using Custom I/O

Hi everyone,

I've been trying to stream MPEG-DASH videos using libdash and decode using
I got the sample player from libdash
working. It can do playback but not seeking.

The sample uses a custom AVIOContext allocated by avio_alloc_context
which takes in function pointers to custom read_packet and seek functions.
The read_packet function
has been implemented but not the seek function.
I couldn't find any documentation regarding the seek function used by
AVIOContext other than the function signature.
So I was wondering if there is documentation or sample code such as
how the custom seek function should be implemented?

Thank you so much for your time.
