Some 4:2:2 streams are not identified as interlaced streams about ksplayer HOT 7 CLOSED

要判断是不是interlaced。你可以直接用ffmpeg的命令来判断。
ffmpeg -I xxx

信息里面有top first, bottom first,top coded first (swapped), bottom coded first (swapped) 就代表是interlaced

当视频是identified的话，那就会输出下面的信息
Stream #0:0[0x100]: Video: h264 (High 4:2:2) ([27][0][0][0] / 0x001B), yuv422p10le(tv, bt709, top first), 1920x1080 [SAR 1:1 DAR 16:9], 25 fps, 50 tbr, 90k tbn

However most of the time, Tracy Player identifies the stream as Progressive

from ksplayer.

and when Tracy Player can correctly identify the stream as interlaced, that is how the playback is:

@cdguy 是在线的流会判断不准，如果是下载到本地的流应该是可以判断准的吧

from ksplayer.

@cdguyIf it is an online stream, it will not be judged accurately. If it is a stream downloaded to a local, it should be able to be judged accurately.

I recorded from a live stream.
However, as you can see here #628 (comment) when I play the stream recording tracy player sees it as progressive

from ksplayer.

@kingslay can you please update tracy player too?
