Broken subtitle track names

[UnknownCoder807]

Describe the bug On my app and in tracyplayer, the names of the subtitles tracks are wrong. In the 2 images below, top one is tracyplayer, the 2nd one is the same movie in VLC.

这个是因为字幕的 name 没有把languageCode 给加进去。可以提供url给我下。然后我调试下吗？或是你可以直接改FFmpegAssetTrack 这个类。 改下下面这个片段

  if let value = metadata["title"] {
            name = value
        } else {
            name = codecName
        }
        // AV_DISPOSITION_DEFAULT
        if mediaType == .subtitle {
            isEnabled = !isImageSubtitle || stream.pointee.disposition & AV_DISPOSITION_FORCED == AV_DISPOSITION_FORCED
            if stream.pointee.disposition & AV_DISPOSITION_HEARING_IMPAIRED == AV_DISPOSITION_HEARING_IMPAIRED {
                name += "(hearing impaired)"
            }
        }

name = codecName

建议metadata["title"]为空时候将 language 作为字幕的名字, 而不是codecName:

 if let value = metadata["title"] {
            name = value
        } else {
            name = languageCode ?? codecName
        }
