subtitles and transcoding

[macv 2]

Hi, just curious what's happening in this scenario: I was playing a 4K movie and, when turning on subtitles, it had to transcode to something less than 4K.

 

- is it a Roku shortcoming to not support subtitle overlay, thus requiring transcoding to insert the text into the image?

- did Emby detect that my machine couldn't transcode in 4K fast enough, and dropped the res so it can keep up?

- any developments in this area in the future?  Or restricted by Roku capabilities.

 

What's the tech/language stack needed if one were to try to contribute to this?

Hi.  What type of subtitles were they?  If graphic, then transcoding would probably be the only option.

 

External text subs are always more flexible.

By graphic do you mean burned in subtitles?

Across couple different files, had both SRT and in-container subs.

Graphic meaning pgs or dvd subs for example

Hi, let's look at an example. Please attach the information requested in how to report a media playback issue. thanks !

Will do that next time as I no longer have the file; 4K files are big!

But the original questions are generic I'd say, not tied to specific files.  Does Roku not support subtitle overlay, requiring Emby to transcode?

Does Roku not support subtitle overlay, requiring Emby to transcode?

 

For graphic subtitles it does not. For plain text subtitles such as srt, it does.
