I have an infinite video feed (m3u8 videos) and I start loading a video once it comes into focus. If user scrolls through videos really fast, then 1st video segment of all the videos start downloading parallely and choke the network bandwidth, resulting in delay in playing current focused video. As a possible solution, I would like to know if there's a way to abort the download of in progress video segments, if user moves to next video. As of now, I'm able to stop download of any new segments, but couldn't cancel the ones which are already being downloaded.

Are you referring to the preload API? A preload manager should abort downloads when you call destroy on it, if it hasn't been loaded by a player yet. If it's not doing so, that's a bug.

Hi @theodab, question is actually valid for both load and preload APIs. Calling destroy on preload manager currently is making fully downloaded segments unusable for future.

Scenario (Given Segment Size ~ 500kb)
User is watching Video 1 (2 segments are completely downloaded and 3rd is in progress)
User moves to Video 2 (1st segment starts downloading)

I'm looking for a way to be able to cancel download for Video 1 - Segment 3, so that user's bandwidth can be dedicated in loading Video 2. But in case user comes back to Video 1, we should be able to play already downloaded segments of Video 1 instantly.

You can:

1. pause() the video - the player will stop fetching when it reaches the buffering goal
2. unload() the player - the player will stop immediately, and you have to call load() again to resume the content

Does this help?
