FPS Variability

[neostck]

On the same live channel, 50 FPS is issued when operated with VLC player and 24 FPS when operated with KSPlayer.

VLC Player:

KSPlayer:

Device: Apple TV 4K OS: tvOS 17.4 (21L227) APP: Snappier 3.0.4 Player: KSPlayer 2.2.4

I only have a personal connection, I can't provide a connection.

你可以看下实时的Display FPS的显示的是多少。或是你在mac上用vlc保存一小段视频片段发给我。

[neostck]

I provided video with KSPlayer above. Now I provide video from the same channel as VLC.

@UnknownCoder807 在Snappier上是否可以看到Display FPS 的值。对应的代码是
LabeledContent("Display FPS", value: dynamicInfo.displayFPS, format: .number)

Yes, I use this code and it appears to work correctly.

@UnknownCoder807 你的意思是FFmpegAssetTrack 中的nominalFrameRate返回的是24 然后 dynamicInfo.displayFPS 返回的是50吗？

No, both show 50FPS.

1st screenshot is nominalFrameRate

2nd screenshot is dynamic

那问题点是：这个视频流在vlc那边显示的fps是24，但是在ksplayer这边显示的fps是50 吗？不知道那个是对的吗

In the case of my stream, it is displayed as 50fps in vlc too.

@neostck 那你看下Display FPS 显示的值是什么？ Display FPS的值是最准的。

[neostck]

The FPS value is 50 in feed broadcasts given with Windows, and the FPS value is 24 in feed broadcasts given with Macbook. We couldn't understand why.

As can be seen in the image, all broadcasts are sent as 50 FPS, but on our devices they have only 24 FPS with KSPlayer.

Why don’t you try with TracyPlayer? Lilly Player tvos app does not have the latest ksplayer libraries

[neostck]

It plays in slow motion.

@neostck 你是否可以用Mac上用vlc录制有问题的直播流，然后发给我呢？只要录制一分钟时长就可以了 录制教程如下： https://juejin.cn/s/vlc录制视频流
