Frame Accurate Seeking

Tue Aug 08, 2017 11:34 am

Anyone know of a trick to enable Frame Accurate Seeking?
I cannot find any documentation that indicates Roku support but just checking to see if maybe (just maybe) it can be done.

Seeking by number of seconds is supported.  As long as the frame you're going to is on a second boundary then that should be sufficient.  If you need to jump to any other frame of video then I think you would need the NDK and write a replacement video player.

When we seek to a specific time in the video (seconds) the player always jumps a few seconds before and begins playback.

Is the framerate metadata set?  Does the issue appear if you are using HLS/ISM/Dash, or just MP4?

If you are using HLS then you will always start at a segment boundary AFAIK.

I am pretty sure HLS seeking will always start on a segment. It might be able to seek to an iframe within a segment, but I doubt it.  Maybe one of the Roku engineers can chime in here.
