    Question Progressive Netstream. Seek to a point not yet downloaded

    I've written a video step carousel that allows you to slide through multiple videos and playback. Also integrated are a chapter system that allows for seeking to specific points in a currently playing video.

    The issue obviously is inherent to progressive download vs streaming and that you cannot seek to a chapter time that has not yet been downloaded.

    I remember (years back, prob as2 days) someone came up with a clever php hack that allowed you to do just this using progressive download but i can't find any docs on the subject.

    Does anyone know of a way this is possible? The client does not have the resources necessary for hosting on an RTMP server so i'm looking for a workaround that doesn't require the entire video to be buffered before allowing seek to specific cue points.

    Videos are around 5 mins in length each so not a huge amount of data to buffer but obviously takes a good 30 secs before the last chapter point is reached and thus, seekable.

    Any ideas as always are much appreciated. Thanks

    If you're bound to progressive download I'd look at cutting up the chapters into individual files, maybe using a low-bandwidth version that you overwrite later (the same way netflix does streaming - where they start you on low quality and then kick up the bandwidth).

    If you find that php solution I'd love to see it.
