关于内嵌字幕和外挂字幕之间的切换

[zdw19840929]

大佬我发现一个问题，就是我这样操作之后字幕的字体大小不对

1. 先设置一个内嵌字幕，然后设置内嵌字幕的subtitlePreference

self.player?.exchangeSelectedStream(Int32(i))

if var p = self.player?.view.subtitlePreference {
                p.color = 0xFFFFFF
                p.ratio = Float(self.subTitleSize)
                p.bottomMargin = 0.07
                self.player?.view.subtitlePreference = p
            } else {
                self.player?.view.subtitlePreference = IJKSDLSubtitlePreference.init(ratio: Float(self.subTitleSize), color: 0xFFFFFF, bottomMargin: 0.07)
            }
            self.player?.view.setNeedsRefreshCurrentPic()

2.切换成外挂字幕

self.player?.loadThenActiveSubtitle(subtitleURL)
            if var p = self.player?.view.subtitlePreference {
                p.color = 0xFFFFFF
                p.ratio = Float(self.subTitleSize)
                p.bottomMargin = 0.07
                self.player?.view.subtitlePreference = p
            } else {
                self.player?.view.subtitlePreference = IJKSDLSubtitlePreference.init(ratio: Float(self.subTitleSize), color: 0xFFFFFF, bottomMargin: 0.07)
            }
            self.player?.view.setNeedsRefreshCurrentPic()

3.再切换到内嵌字幕

self.player?.exchangeSelectedStream(Int32(i))

if var p = self.player?.view.subtitlePreference {
                p.color = 0xFFFFFF
                p.ratio = Float(self.subTitleSize)
                p.bottomMargin = 0.07
                self.player?.view.subtitlePreference = p
            } else {
                self.player?.view.subtitlePreference = IJKSDLSubtitlePreference.init(ratio: Float(self.subTitleSize), color: 0xFFFFFF, bottomMargin: 0.07)
            }
            self.player?.view.setNeedsRefreshCurrentPic()

这三步操作之后，字幕的字体大小不对了，变得特别小。

这个问题不再做修复，最近正在开发一套新的字幕挂载-解析-渲染-上传纹理的引擎，跟当前这套实现完全不同了。
