iPhoneX还是闪烁，但是换成iPhone12 pro max就不闪了，和硬件配置有关系么

debugly commented 6 months ago

没在iPhoneX上进行测试。 ass 字幕渲染的确会消耗一定的cpu，具体跟字幕里的特效有关系。 通过日志看确实是ass渲染跟不上视频播放的速度。 你可以换个简单的ass字幕试试，或者把你测试的ass字幕发出来。

我测试极限播放的是4K视频，视频体积达26G，考虑也有可能是视频体积过大导致渲染跟不上引发的，实际测试下来大部分ass字幕或pgssub字幕都可以渲染

打开hud，看下frame-drop指标，如果一直在丢帧，那么有可能出现这个问题。

看起来frame-drop一直没变化是0，代表没丢帧？

debugly commented 6 months ago

没有丢帧。 这种卡拉OK效果的字幕比较消耗性能，正在想办法优化。 在iphonex上，那种正常的一句一句的对白没问题吧？

没有问题，非常流畅，可以正常显示特效字幕，符合预期

k0.11.2 版本进一步做了优化，你可以使用 iPhoneX再试试。
