is this ok?

This should be moved to the Linux sub as this is not a windows server problem, this is a linux server problem, possible docker.  There are also dropped frames, which should not be happening, which means it's a server end problem.

Are you using a docker or what?

 maybe this addresses the problem?  It would also help if you said what hardware is on the server.  I know it's in the log, but it would be easier so other people know.  I know there have been serious issues with quicksync and dockers on debian, and I will admit I know pretty much nothing when it comes to dealing with it. All I can do is googlefu.

thank you,my hardware is J4125

@lihouyu001 - Does it work when you playback without subtitles?

Does it work when you select VAAPI encoders and decoders instead?

20小时前，softworkz说：

@lihouyu001- 当您在没有字幕的情况下播放时，它有效吗？

当您选择 VAAPI 编码器和解码器时，它是否有效？

我已经尝试了你的项目，没有绿屏。但是转码效率有点低，所以我决定放弃这个视频。谢谢！

I have tried your project and there is no green screen. But the transcoding efficiency is a bit low, so I decided to give up this video. Thanks!

In one of the upcoming betas (next or one after the next), we will have hardware overlay for subtitles which will provide much better performance for subtitle burn-in.

Thanks,

Out of curiosity, do those green screen happen only with Emby?

If you try VLC or MPC, do you get any green screen.

 

I have got a few of those myself, after transcoding with xMediaRecode (to decrease file size) and saving subtitles.

Source file is OK, transcoded file without including subtitle also OK.

The subtitles were appearing on green background, instead of video.

Moving video frames back and forth between memory requires a lot of memory and a lot of CPU

In one of the next beta we will do subtitle overlay in hardware, so it won't be required any more to download video frames, overlay subtitles and the re-upload again for encoding.

[softworkz 5066]

On more thing you can try when you get message about low video memory:

Boot your machine and go into BIOS. At some place it is possible to configure the integrated CPU graphics (iGPU). Find the setting where you can choose the graphics memory to be assigned: Choose the maximum (e.g. 1024 MB) instead of "Auto".

@lihouyu001 are you still having an issue with this?
