Ticket #1483 (closed enhancement: fixed)
Allow a list of keyframe numbers that are valid for starting a new segment

It would be beneficial to have an option with the segmenter to white list keyframes that can be used to start new segments. The duration of the segment would not cause a new segment to be created until a keyframe in the white list is reached.
This will allow videos that have a subset of common keyframes to be segmented and maintain common starting points. Otherwise, a constant gop is required which is not optimal.
My feature request will allow the encoder to optimize keyframe placement for different quality levels of the encode in variant streams without risking playback getting out of sync between the variant streams which makes swapping between streams impossible.
Adding a command line option to input a comma separated list of frame numbers would be an easy way to implement this. Then the list can be checked against the current frame number when outputting packets into segments.
