There is no reason to use pointers to 32bit values, all operations are based on bytes. So This removes alot of extra casting and potential pointer arithmetic errors. Also provide some functions for calculating header values to reduce duplication and improve readability.

I don't think it's semantically right to use uint32_t for byte lengths? I'd suggest size_t. (Not that this matters practically.)

I totally agree and plan to convert to size_t both in the public API and internally, at the moment the mix of size_t, uint32_t, int and unsigned int is just staggering in this project. But such a change in the public API needs a major version bump which is why I have been putting it off. I think it might be a goal for the Christmass break to start.

srtp_get_rtp_xtn_hdr & srtp_get_rtp_xtn_hdr_len both assume that the caller has verified that the input arguments are valid, ie that there is an extension present by previously checking the x bit of the RTP header.
