Mathieu Duponchelle 2fa15d5371 event: add new seek parameter, "trickmode-interval"
When performing a key unit trickmode seek, it may be useful to
specify a minimum interval between the output frames, either
in very high rate cases, or as a protection against streams
that may contain an overly large amount of key frames.

One use case is ONVIF Section 6.5.3:
