Changing the Speed on video players (both Stride and Skia) introduces a short frame drop at every speed change if the video is quite large (GB sized). The speed input in the HAP player does not work at all, anyway for preactical reasons, as the mp4 file weights already a couple of hundreds GB, I am not sure I could use a HAP file. For the same reason using a frame sequence would be inpractical.
Well this is done via sequences or hap primarily… The hap has issue changing between videos but not scrubbing the video it’s already opened… Not sure how the file size impacts this? Generally speaking mp4 playback is not something that can be controlled in realtime, e.g. it’s like player: “slow down”, yea sure, I will slow down eventually… the media player runs on separate thread it’s kind of no way to control its behaviour. I’ve seen ffmpeg VL nuget maybe try to check for it?
