Nvidia shield OTA transcoding

[syadnom 25]

Though there is a thread with some comments on this, it's 60 pages long and not specifically about shield+OTA

 

I setup Emby Server on a Shield, verified that transcoding is 'Yes' and the profile is auto.

 

The dashboard shows MPEG2 MediaCodec > H.264 (AVC) MediaCodec

 

video constantly stutters.  Completely unwatchable. 

 

If I disable hardware transcoding, the video plays smooth but of coarse uses up the entire CPU on one or two 480p transcodes.

 

Now, If I selectively disable/enable the transcoder

 

software MPEG2 > MediaCodec H.264 - still stutters but maybe 25% as bad

MediaCodec MPEG2 > Software H.264 - full stuttering

MediaCodec MPEG2 > MediaCodec H.264 - full stuttering

software > software - plays fine

Emby Server > Emby Player on Shield direct plays MPEG2 and plays fine.

Basically, the Shield is completely useless for this purpose... and I'm only using 480p TV streams.  I cant do a full 1080p MPEG2>H.264 in software without stuttering.

Have you tried enabling the direct stream live tv option in the app?

I need it to transcode specifically.  I can direct stream on devices (not browsers, no MPEG2) but I MUST transcode for my needs.

Can you provide an ffmpeg log from a stuttering example? Thanks.
