There's a same question already there . posting it again . Hi. We have a custom player and would like to implement trick play(show preview thumbnail of the content as user scrubs on the slider). Stream format is .m3u8 and the manifest does have "EXT-X-I-FRAME-STREAM-INF" tag mentioned in specification. But we are clueless about how to utilise it and show thumbnail above the slider. Looking forward to the help. Thank you. I have achieved it using sprite image and cropping and showing it above the slider but I would like to opt for the recommended way by apple . Please help if anyone have implemented trick play in custom AVPlayer Brightcove iOS sdk has done it would like to know how they achieve it . https://github.com/brightcove/brightcove-player-sdk-ios (section - Thumbnail Seeking )
