The warning from gst is correct, it's a driver bug. But as you can see, it has a workaround.

For example if the place we want to seek to is just before a key frame then the seek will be very slow (I've seen up to 3 seconds), but if we know where the key frames are, then it might well be acceptable to seek instead to the key frame just after the desired point. I have written a "pre-scan" technique which locates all key frames in advance. It works by seeking to the next key frame (flags GST_SEEK_FLAG_KEY_UNIT | GST_SEEK_FLAG_SNAP_AFTER), get the location, add a little, then seek from there to the next key frame, etc. But this can take 10 or 20 seconds on large videos. So my first question is, is there a faster way of doing such a pre-scan? Failing that, I'm thinking of collecting key frame positions incrementally while we play, using a pad probe. I tried placing a pad probe after decodebin but I find *none* of the buffers have GST_BUFFER_FLAG_DELTA_UNIT, so they all appear to be key frames, which is wrong of course. According to this very old post: <a href="http://gstreamer-devel.966125.n4.nabble.com/keyframes-from-a-video-td973102.html" rel="noreferrer" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/keyframes-from-a-video-td973102.html</a> "- decodebin outputs decoded raw video frames; I don't think the semantics of keyframe/not-keyframe are very well defined for raw video frames. I would not rely on decoders flagging their output buffers consistently one way or another or at all - you are likely to get better results if you check for keyframes on buffers before they go into the decoder" But how can I do that? Do I need to investigate the internals of how decodebin works? Any advice would be welcome.
