The closest there is to your requirements, ie:

(a). A container format with support for timestamps such as mpegts

(b). Capabilities similar to UDP

Would be Haivision's SRT, which FFmpeg supports if enabled on build time
via --enable-libsrt.

SRT allows for optional encryption, whose details can be viewed via ffmpeg
-h protocol=srt.

Note that depending on your application requirements, you'll need to ensure
that your receiver can handle SRT input, OR use FFmpeg to handle SRT TX and
Rx in the network segment where such content security is desired.

Hope that helps.
