Transcoding on web app but not Infuse

[mannyrothman 10]

I just installed Emby on my Synology and it's working well except that when I browse a 4k HEVC HDR MKV file, Emby Web has to transcode everything. However, if I use Infuse and connect it to my Emby server, it direct plays the same exact file with no transcoding needed. What is going on here?

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

I am using Arc Browser, based on Chromium, I believe.

Attached are the stream stats and relevant logs.

Thank you!

Your screenshot shows the reason for transcoding. Does that answer your question?

But I'm confused why transcoding has to occur if the same file can be played directly without any transcoding using the Infuse app on the same computer. Why would this be?

Nothing to be confused about. There is no web browser that supports TrueHD audio.

Ah I see. Do browsers also not support mkv files?

What would be the ideal video format/codec/container/audio/etc for streaming universally?

Chrome and edge do. Others no

In my experience it is mkv/h264/aac with vtt or srt subtitles.

I believe mp4 is more widely supported than mkv across browsers.

I often get choppy playback from mp4 that is fixed simply by changing container.
