Why transcoding?

[fbrassin 47]

Hello,

as i would like to try adjust my movies to not make my server transcoding them i would like to understand what causing trancoding.

Can you help me to understand where to watch in the log cause of transcoding?

 

My server has got ubuntu 16.04

My client ATV4

 

Here is log of trascoding:

This may help but not so sure.

When you’re in the dashboard and see the currently playing items that are transcoding, there is a little info icon. Clicking on this should bring up another window that will tell you the reason it is transcoding.

 

More often than not it is because of format. I recently started using mp4automator to turn everything into mp4 format and this has greatly reduced my transcoding. Another reason could be because of bandwidth options. If someone has a lesser connection it will transcode to a lower bitrate to be able to watch it. With mp4s even when they do transcode because of bitrate it seems to be less taxing on my CPU.

- apple doesn't support mkv container

- subtitles are being burned in

 

if you want to avoid all use of ffmpeg, switch to mp4 and add external subtitles.

That is strange, there are some .mkv that on ATV i can watch in direct stream or romux, no transcoding.

Which are the differences from the previous one?

 

Here are two examples:

direct stream

Remux

The audio

I cannot understand why this movie was transcoded https://paste2.org/epa7IJvv

 

 

 

 

While this was remuxed https://paste2.org/Ms11P80s

 

 

That movies seems to have the same codecs for video and audio.

What i don't understand? 

I'm confused

The first one has forced subs that were selected by default.

 

The second one doesn't.

But i tried to start both in the same way, pressing play botton without changing anything.

In playing settings i have smart subtitles.

For the remuxed movie i could see subtitles.

And none of the 2 movies has got external subtitles.

 

This is what i cannot understand.

The "smart" subtitle setting is going to select forced subs for display when you play something - unless you have played it previously and turned them off manually.

 

The fact they are burning in must mean you have the option to extract internal subs turned off.

Where is this option?

Do you mean option in emby?
