I have installed the new AppleTV App!

It looks great, but the playback very often stutters...!
I use a dlna-Server from my Mac (twonky)...

I have tried another AppleTV App (dlna Client) and there everything plays Fine without Stuttering!

Whats wrong with Infuse??

The files are Apple conform mp4-files, so no transcoding is needed...!

I also experience some stuttering which was not present on Infuse with ATV2. I have a 4K TV - is this perhaps the reason?

Same here, it is not a bandwith stuttering, loading time and timeline jump is really quick, the stuttering is unregular and minimal , i got a similiar effect when i turn off the 24p playback option on my panasonic bdt-500

yep - same here - its hard to describe - not smooth playback, looks like lost frames on fast movements here and there - definitely not a network throughput problem as plex or airvideo hd play the files smoothly on the apple tv from the same location.

Same stuttering here... I belive that the reason is that infuse is using its own player and not the native apple tvos player... that´s why the infuse player does not need to transcode/remux anything server side... but something needs tuning.

I posted this yesterday: http://firecore.com/forum/topic/13648

Do you use 50 or 60 hz? I had problems with stuttering in different apps when display was set to 1080p 60hz but switching to 50 hz made it way better.

I also experience small jumps every few seconds. I play my files from a synology nas with smb. My Apple tv is connected with the 100 base-t port to à gigabit switch. All my files are 1080p mkvs. I think we need the nfs protocol for smooth playback.

There were reports of stuttering during the beta test, i was advised to try wifi 5gz (which i did but made no difference)

I purchased the app though as its a great product but I still believe this needs looking into.

The stutter issue i´m experiencing has nothing to do with buffering, ethernet/wirespeed/duplex or wireless frequence (that would all cause "unstable" playback).

The constant playback stutter iám experiencing has to be a framrate issue!

Source = 23.976
ATV4 = 50 or 60

To play source material with a different framerate than used by the playback device, you need to do some magic (pulldown, frame insertion etc.) as neither 60 & 50 fps is devidable with 23.976.

I have always used XBMC/KODI and always set the display refresh rate to match that of the source... but Apple does not allow any other setting than 50 or 60.

But Apples native player is really remarkably good at the "magic" framerate manipulation, and the Infuse player currently is not (i hope they will catch up thou, as i really like the infuse app)

Thats a bummer, that type of stuttering is really annoying. You might be right, maybe the native apple media player is better att adapting the framerate.

Lets see how kodi (mrmc) handles this when it will be available in the near future.

I´am only speculating offcourse, but playing back the same h.264 files, from the same NAS (no transcode) shows a very big difference - sadly in the native OSTV players favor, so I´am pretty sure that has to be the root cause.... hopefully something the firecore team is able to address in a fix.

I’m also experiencing heavy stuttering in a lot of mkv-files. Sometimes it happens immediately, sometimes after a couple of minutes. I’ve tried wired as well as over WiFi (5 GHz) but the result is the same. My aTV is connected to an amplifier which is connected to my TV. I’ve also connected the aTV directly to the TV but that setup also gave me the same stuttering.

My mediafiles are on a MacMini (2012) with OSX El Capitan. I’ve even disabled all other tools and utilities that were running on the MacMini but that also didn’t make any difference at all. I’ve tried streaming the files from a share on my MacBook Air, unfortunately still the same stuttering.

This is such a disappointment, I was so looking forward to Infuse! Now it’s back to plex for me until this issue will (hopefully) get resolved. If I can be of any help analyzing the problem then please contact me as I’m happy to help trying to solve this.

I have also the problem.

When i play the video files over my Ipad / Infuse App / Arplay, the stuttering not present with this combination.

I think the Player in the Infuse App transcoding the video file and have frame drops from time to time.
I hope a update brings an improvement.

I might be wrong, but i dont think there is any transcoding going on. Only decoding.

We're looking into a few cases of this, and hope to have the issue resolved soon.

In the meantime, the more info we can get about the affected files the better - so if you have a moment to provide a bit more info it would be very much appreciated.

  1. Run one (or more) of the video files through MediaInfo (Download links: Mac - http://fireco.re/YCm3 and PC - http://fireco.re/YCY2)
  2. Open a support ticket at http://support.firecore.com/hc/en-us/requests/new and attach the specs
  3. If you also want to provide a few details about the type of device you're streaming from, that could also be helpful

Thanks!

Infuse 6 for iOS and Apple TV is now available!

I have grey artefacts on the screen every few minutes during playback.
Is this the same problem that you all have?

I don't know when it happens, but it happens only in a few movies.

Sounds to me like an encoding thats not fully supported by the ATV. You can check the encoding in i.e. VLC

I have the same problem here. Playback stuttering for all my movies. Its really noticeable. Does is it linked to 24p in 60fps stream output?
I opened also a ticket with some media info of files.
Hope it will help for a fix to come.

What about x265/hevc playback 1080p, it works, but with stills, the audio is good, but 1 frame a second. the atv4 is powerful enough to playback. will t work in a future update?

Same, when playing exact same file with the native Panasonic "Media Server" smart TV app, flawless processing.
Maybe it has something to do with the receiver post-processing the AppleTV?... Anyhow, the receiver is Onkyo TX-NR525 and I also have it with an Onkyo TX-NR727. That last one has got plenty of horse power so it has nothing to do with the processor not being able to handle the file.

Experiencing the same stutter/judder. Switching to 50hz makes it a bit better but still not smooth. Maybe it has something to do with 24p playback (come on Apple, we've been struggling with this for a long time). Hopefully firecore can shed some light. Meanwhile the stutter renders infuse useless Frown

Experiencing the same things as you guys are describing. Very disappointing as most of my video's are shuttering and what seems like dropping frames. Hopefully they will fix soon as I love everything else about this app and the main reason I upgraded to the new ATV 4. I submitted a ticket with Mediainfo as James requested.
