Sammy 735 Posted March 2, 2019 Share Posted March 2, 2019 Quick question.. Why does AndroidTV / ShieldTV transcode while Samsung Tizen Direct Play? Of course Direct Play tunes lightning fast comparatively. Thanks. Sent from my SM-G960U1 using Tapatalk Link to comment Share on other sites More sharing options...
CBers 6766 Posted March 2, 2019 Share Posted March 2, 2019 Why does AndroidTV / ShieldTV transcode while Samsung Tizen Direct Play? All depends on what you are playing on the Shield, although I rarely have anything trancode (remux) on my Shield(s). Not all devices are the same, so some will need to have the source transcoded to match the capabilities. Link to comment Share on other sites More sharing options...

ebr 14903 Posted March 4, 2019 Share Posted March 4, 2019 Have you turned on the option to direct stream Live TV? Link to comment Share on other sites More sharing options...
Sammy 735 Posted March 4, 2019 Author Share Posted March 4, 2019 Have you turned on the option to direct stream Live TV? It is my understanding that Direct Stream in the AndroidTV settings will not allow for FFWD and RWD or Pause/Play? I didn't find such a setting in the Tizen App but it allows for FFWD and RWD or Pause/Play but I'm not seeing the CC's exposed on Tizen. Link to comment Share on other sites More sharing options...
ebr 14903 Posted March 4, 2019 Share Posted March 4, 2019 It is my understanding that Direct Stream in the AndroidTV settings will not allow for FFWD and RWD or Pause/Play? Correct but, at the time you want to pause, you can easily switch to the mode that will allow it (the app will prompt you). So, you could turn on that option and have faster tuning while surfing and only turn on the remux when you need it. Link to comment Share on other sites More sharing options...

Any way to somehow incorporate that automatically into the app? Maybe have it direct play to the display but transcode in the background to a pause buffer? Just thinking out loud here for a way to improve the playback of LiveTV. Of course if it is interlaced 1080i OTA it has to transcode anyhow as it says interlaced video is not supported (on the ShieldTV). Link to comment Share on other sites More sharing options...

And what is the state of the option to de-interlace HD on the server...? Link to comment Share on other sites More sharing options...

ebr 14903 Posted March 4, 2019 Share Posted March 4, 2019 Where to check? In the app's playback settings. Link to comment Share on other sites More sharing options...
Sammy 735 Posted March 4, 2019 Author Share Posted March 4, 2019 It is checked on for both SD and HD. Should I check it off to allow the TV to de-interlace or will the ShieldTV do it if checked off? Link to comment Share on other sites More sharing options...
Sammy 735 Posted March 4, 2019 Author Share Posted March 4, 2019 Wow! that boosted tune time tremendously for interlaced content. PremiumTV h.264 still takes a while to tune. Link to comment Share on other sites More sharing options...
Sammy 735 Posted March 4, 2019 Author Share Posted March 4, 2019 Actually it is quicker but not as quick as OTA. Thanks @@ebr ! The LiveTV WiKi makes no mention of this and The AndroidTV WiKi doesn't really discuss LiveTV or interlaced content. All that said, I'll be changing the settings on all my ShieldTV's today!

Sammy 735 Posted March 4, 2019 Author Share Posted March 4, 2019 Now why would playback of the same content on two different ShieldTV's be different? One is direct stream and the other is transcoding? This is PremiumTV BTW.. Link to comment Share on other sites More sharing options...
Spaceboy 2493 Posted March 4, 2019 Share Posted March 4, 2019 I couldn’t see any benefit from having those settings on in terms of quality of picture. And yes it’s several orders quicker without them Link to comment Share on other sites More sharing options...
ebr 14903 Posted March 4, 2019 Share Posted March 4, 2019 Whether those options help or not depends on the equipment involved but the HD one is off by default so you turned it on at some point. 1 Link to comment Share on other sites More sharing options...
hayrund 14 Posted April 17, 2019 Share Posted April 17, 2019 Will there ultimately ever be an option to Direct Play and have the ability to use FF/RWD/Pause on Android TV or Apple TV? I noticed the exact same behavior on my Samsung TV. Tuned instantly and had FF/RWD abilities, while my FireTV, AppleTV, AndroidTV do not. For clarity, Apple TV is Apple TV 4K, Fire TV is Fire TV box gen 2, Android TV is nVidia Shield TV. Link to comment Share on other sites More sharing options...

hayrund 14 Posted April 18, 2019 Share Posted April 18, 2019 Yes. Using HDHomeRun Quatro to tune OTA channels in U.S. On every client with the exception of Samsung Tizen TV, it is transcoding somehow and thus causing the tuning delay of 10+ seconds when tuning to a channel. If I enable DirectPlay in options and thus disable the ability to pause/rewind/etc, it tunes extremely fast and shows Direct Play. If this option is disabled, it takes 10+ seconds to tune (on nVidia Shield TV) but I have the ability to pause/rewind/etc. It shows: Play method: Direct Stream, Stream type: HLS, but in the streaming info, it's showing a transcode speed as it is transcoding. I should also point out that audio/video gets slightly out of sync about 1 out of every 5 times. 1 Link to comment Share on other sites More sharing options...

We are constantly looking to improve the speed of this. Thanks. 1 Link to comment Share on other sites More sharing options...

I would love it to be as instant as my Tizen TV or even as fast as my Apple TV. Link to comment Share on other sites More sharing options...

A consistent 2 to 3 seconds or less is desirable though. Even WMC took a sec or two unless it was CableCARD with a Prime with a Tuning Adapter whereupon it took 3 to 5 seconds.

Carlo 4330 Posted April 23, 2019 Share Posted April 23, 2019 I lot of this is CPU resource dependent on the server. For example if you happen to run MCEBuddy which is CPU intensive when scanning, cutting or converting files or have other files in Emby that are transcoding then it affects the speed of loading channels when these channels also need to run through ffmpeg to remux.

mrfragger 39 Posted April 23, 2019 Share Posted April 23, 2019 Changing the format to what specifically? Are you referring to HLS (Streaming SRT subtitles). What is preventing it from seeking initially? Link to comment Share on other sites More sharing options...

We are constantly looking to improve the speed of this. Thanks. Is there a reason that you need to swap containers? Why not just do the pausing fast forward rewind in the ts container? That said, seeking in Emby LiveTV is working really well right now. Sent from my SM-G960U1 using Tapatalk Edited April 24, 2019 by Sammy Link to comment Share on other sites More sharing options...
