FireTv Transcoding

[LuFi 0]

Hello,

 

Currently, I am testing a lot in Emby to see if I am buying a premiere license.

Today i tried play one of my old recoded recordings. The Episode was Recoded in XVID but Emby Server always transcode it for my FireTv.

FireTv supports XVID, why this fille needs to be recoded ?

 

Also i enabled Hardware Support on my System, but why this is not used for this file. It should be possible to decode it by using CPU and recode it by GPU ?

The AVI container is not supported on the Fire.

 

Also, the below specs indicate mpeg4 is also not supported.

So i guess a good question would also be which gen of fire tv is it?

Looks like only the 3rd gen ( so far ) does not support mpeg-4.

As far as GPU transcoding goes, it might not be so simple. What OS are you using? Do you know what hardware acceleration your system supports?

FireTV 2 Gen i think. Menu is new Design but no Alexa Remote.

 

OS is Ubuntu 18.04 Server.

I am not sure how to tell between 1st and 2nd gen fire tv's but the 3rd gen has a hdmi cable built in. 

 

As far as the container and media things go i am lousy at remember what can do what.

However i would believe that you can use va-api for hardware acceleration, quicksyn seems to be supported mostly by Microsoft.

First thing i would check would be to make sure emby ( the system user ) is part of the video group.

 

Out of curiosity, did you look at the transcoding log to see if it was using the gpu or cpu?

CPU was used

Ok, Then first thing i would check simply because it is the easiest would be to make sure emby is part of the video group, and of course that the right path is under va api device. For referance mine is /dev/dri/renderD128 your might be different though.
