F4V Does Not Support Cue Points

Despite appearances…

misleading cue point ui

F4V files (otherwise known as MPEG4-AVC / h.264 + a special Flash only file extension) DO NOT SUPPORT CUE POINTS. Unfortunately, no good tooling support for timed text tracks replaces them.

    Well, I’m not sure about you, but I prefer to use events in my players that load the cuepoints via text or XML files and then use the playhead time to trigger them. I know it’s sort of re-inventing the wheel, but it allows the cuepoints to live in a database and be updated dynamically without the need of editing the file.

    For the record, I forgot to mention that ActionScript cue-points not embedded in the video file work correctly, since they are a function of the AS language, not of the file format.

    Is it possible to use cue points with an H264 encoded videostream put in an FLV container?

    @Justin Actionscript Cue points are not accurate (at least from what i tested).
