Buffer limit

[arthurgeron-work]

I'm using this lib on react-native, it renders a feed (Youtube Shorts like) and I'd like to limite the bandwidth non-focused videos use, currently that's impossible because I can't set/limit the buffer size on the current params.
It'd be great to have this feature.

Hi @arthurgeron-work, have you tried the initialBufferDuration prop? https://github.com/aws/amazon-ivs-react-native-player/blob/main/docs/ivs-player-reference.md#initialbufferduration-optional

You can also limit the quality of the non-focused players: https://github.com/aws/amazon-ivs-react-native-player/blob/main/docs/ivs-player-reference.md#automaxquality-optional

@maxstoller could you please elaborate a little more about initialBufferDuration? I really couldn't measure anything when I played with values between 1-5. Should I set a value of 0 for non-focused players?

Hi @hirbod,

The initialBufferDuration API controls how much video the player buffers before it starts playback.

Lower Value: Playback will start faster, but the viewer may experience more rebuffering due to the small buffer.
Higher Value: It will take longer for playback to start, but the viewer may experience less rebuffering due to the larger buffer.

I really couldn't measure anything when I played with values between 1-5.

You may not notice a difference on a fast connection.

Should I set a value of 0 for non-focused players?

The minimum is 100ms.

Can you share more info about your use case and goal?

@maxstoller thanks for the explanation. I created a TikTok/Instagram like reel. I have 3 videos pre-rendered (FlashList) and I want to prevent consuming too much bandwidth before the video is visible. I wasn't really sure what to pick. It's important for me that playback starts super fast without having to pre buffer too much.
