Describe your issue

When I download video from youtube in this way : "remux best video with best audio",then I get a mkv video [video-vp9 & audio-upos].However,this mkv video can not play normally in “network flow”：The time progress bar cannot be displayed normally, and the video progress cannot be dragged.I must download the whole mkv vedio file and play it in some player with fremg decoder such as potplayer and mxplayer[nplayer can not play normally even the whole mkv file is in local] ,if I want to play it with "right time progress bar".


Both of them are in Internet video streaming

Comparing the information of the two, it is found that the mkv video mixed by the server lacks some playback information, and the mkv video that is re-distributed and packaged through mkvtoolnix can be played normally both locally and in the stream.

I tried youtube-dl and yt-dlp,and them showed the same problem.

This probably happens because the MKV is encoded on the fly and streamed to the browser so it does not know how long the complete file will be.
