Am using MPMoviePlayerController to stream n play a video. Its, in m3u8 format and plays with no problems. However, lets say it has buffered n played 50% of the total video, now if i seek backward, it starts buffering from that point. shouldn’t it just play the video and not buffer from the seeked point as it has already buffered that part..??

This behaviour is observed only in case of m3u8 file, if I play a mp4 file, it doesn’t do that. I mean, it won’t buffer again.

So, is this an expected behaviour or am I just missing something..?

Thanks in advance.

    m3u8 is a playlist file. It has links to either other playlist files or video files in TS(transport stream) format. The ts files are most commonly 10 seconds chunks of video. So, every N(10) seconds it fetches a new stream.So, when you seek, it will go and fetch the stream that had that chunk of the video. So, you will see buffering again.
