Hi !

There is something I don’t understant with Plex transcoding.  
I have an Samsung A5 and since many updates, Plex has added ExoPlayer to the Android App. And it’s fantastic ! Many videos are played in “Direct Play”.

But one i try to sync the same videos, it has to be converted…

When streamed (direct play) =\> [https://imgur.com/a/UmBQo](https://imgur.com/a/UmBQo)

When synced (conversion) =\> [https://imgur.com/a/Bh6XK](https://imgur.com/a/Bh6XK)

Why would Plex do a conversion when obviously my phone is capable of playing it directly ?

EDIT :

**By Looking at the logs, the conversion happens because plex thinks my phone does not support ac3. But it does since I enabled it on my phone settings and I can direct play the video when streaming** =\> [https://imgur.com/a/FQzS1](https://imgur.com/a/FQzS1)

I suspect the ac3 parameter is not checked when syncing…
