Buffering when playing .ts files (also noticed my computer seems to cap the stream to around 15~Mbps)

_dstrukt.n1ne · November 25, 2017, 5:42am

I’m getting stuttering issues when playing back .ts files (due to high bitrate?) but I have more than enough external and internal bandwidth (802.11ac, CAT5e, Gigabit switches and router)

If I play it locally via my computer’s media player, it works flawlessly.

In the Task Manager, I noticed my ATV is only getting about ~15Mbps when there’s a LOT more bandwidth available. I can open a heavy bandwidth intensive app that saturates my network, but Infuse will stay around ~15Mbps

I just upgraded and installed 5.6.2.

The overall bitrate of the file is 18Mbps so I assume that’s why I’m having issues since Infuse won’t exceed ~15Mbps.
Now, I use Plex as well and the bitrates it handles is much larger (confirmed by my network monitoring)
Any idea why the app doesn’t use more bandwidth?

Are you using an ATV4 or ATV4K?

There is limited support for interlaced 1080 content on Apple TV 4, but these will play much better on the Apple TV 4K.

_dstrukt.n1ne · November 25, 2017, 5:04pm

ATV4.

But Plex can stream at a higher bitrate without transcoding the video

james · November 25, 2017, 5:08pm

The issue here is the interlaced nature of the video. This unfortunately isn’t supported by the hardware decoder, and will need to be played in software - which is slower.

I believe transcoding would be required in Plex for this video.
