Playback stutters/freezes occasionally on Android TV and constantly on Web - dinosm - 2023-12-31

Hi everyone!

I have Jellyfin installed on a remote VPS. Media is on cloud storage via rclone. Most watching is done on a Shield Pro. Server upload is 1Gbps and my home broadband is 900Mbps. iPerf confirms I can get near max speed from the server to my home devices. Everything is on gigabit ethernet at home.

I have been using Jellyfin for about two months now, and experiencing playback freezing. This has only ever happened on the Shield, and mostly on high bitrate 4K content. It also happened on an HD movie once in these two months.
On the Shield, freezing can happen at any time, randomly. For example, last one was on a very high bitrate movie that had been playing for about 2 hours before it happened. It could happen near the start of a movie, or at any other point. It can be one or two freezing bits for a few seconds, then it resumes by itself, or freezing and never resuming. When it happens, usually I can exit the app, re-enter it and the movie resumes fine. Sometimes it has not resumed (or it has resumed with freezing), but usually exiting-reentering the app works (which, I think, tells me it's not any sort of cloud storage throttling).
Everything I watch is Direct Play by the way, no video or audio ever gets transcoded (nor do I want it to).

I can then go on to watch 2-3 other high-bitrate movies without a single freeze, only to happen again at some random moment later on or the next day.

I unfortunately have not yet saved any logs at the time it happened, but I have looked at the logs on a couple of recent cases and couldn't see anything relevant at all, other than 'Slow HTTP response', but the logs are usually littered with that even when the media is playing fine.

Now, I have started trying to watch on the web on my laptop too. Here, it is unwatchable. Unless I select 10Mbps (which ends up transcoding video and audio), every movie I try starts freezing from the first few seconds, plays a few seconds, then freezes again and so on.

Plex used to work fine on its web UI, so I don't think it's anything to do with bandwidth, however all suggestions are welcome. At least with regards to the web issue there must be something the matter with Jellyfin Web as the same media play fine on the Shield (with the caveat they can freeze at any moment).

If anyone can help me debug this, I'll be forever grateful!

Here's the log from just trying to start a 1080p movie on my laptop right now:

RE: Playback stutters/freezes occasionally on Android TV and constantly on Web - tmsrxzar - 2023-12-31

"PlayMethod=Transcode, TranscodeReason=VideoCodecNotSupported, AudioCodecNotSupported"

it is transcoding because your browser does not support the video or audio

does your VPS have a GPU available?
is hardware acceleration setup?
what does the ffmpeg log say on the server?
what is the server load when trying to play something that needs to be transcoded?

RE: Playback stutters/freezes occasionally on Android TV and constantly on Web - dinosm - 2023-12-31

Thanks for helping out!

I thought it might be Firefox not supporting HEVC, but the same happens with Edge (which I thought supports HEVC, I have bought the codec from the MS store ages ago), and it also happens with the Jellyfin Media Player which I thought was made to solve these codec problems?

No GPU, no HW acceleration available. Transcoding works fine (at 10Mbps bitrate), but I'd rather everything direct played to get maximum quality and less load on the server.

Good call, I forgot about those. I just left a video stuttering twice on direct play, but no log was generated. Logs were generated when the video initially started playing transcoded, but nothing for Direct Play 🤔
If it generates one later I'll edit this post and add it.

need to address each individually

ffmpeg logs will only be generated when transcoding

for the browser;

when the browser is asking for transcoding, the ffmpeg log then should be available for when the browser is stuttering
my expectation is that log will show a low framerate from ffmpeg when encoding because of the lack of GPU acceleration, the server load will likely show high usage to accompany this
(sidenote: in my experience browsers are terrible jellyfin clients and an official should be installed when able)

for the shield;

if it is direct streaming there will not be an ffmpeg log generated, this is what needs to be confirmed to isolate the issue to either client side or server side
if it is truly direct playing and not transcoding then it will be client side and then things on the client side need to be looked at
some reports on android regarding DTS on shield causing stuttering but typically more pronounced than the occasional you are reporting

Browser:

Alright, so when the browser (or the Jellyfin Media Player) plays a transcoded video at 10Mbps, everything is absolutely fine. There are no issues with transcoding, or with the server load while transcoding. The issues only show when I try to Direct Play.
I do have the official Jellyfin Media Player installed on my Win10 laptop, it behaves in exactly the same way.

Shield:

We are only talking about Direct Playing here, no transcoding is ever done. Everything always direct plays (I always check). The vast majority of the media are in Dolby DD+ or TrueHD sound, these are the ones freezing. Incidentally, since you mention it, I have watched some 4K movies in DTS and they did not freeze at all.

since you have found the happy place for the browser

on the shield; if you're not running the latest client version from the play store go ahead and try that first
if it is the newest from there then try the latest from github https://github.com/jellyfin/jellyfin-androidtv/releases
if it is the newer overall and there is no newer version to test with then i would proceed

it would just be best to ensure this has not already been resolved

Happy New Year!

My Shield is running 0.16.2, which is also the latest version on GitHub.

Does it have anything to do with your cloud storage? Your server's connection is 1Gbps. But that only matters if your cloud storage is actually sending your media anywhere close to that.

How quickly does your cloud storage send media?

If I use rclone to copy a file from a OneDrive remote to local storage on the server, it transfers at around 80MB/s (MegaBytes) pretty much sustained.

I'll need to look at rclone logs when the freezing happens again to see if anything of interest is in there.

I'm having the issue on a shield (not pro, the tube) of stuttering or pausing when playing really high bitrate files that are transcoding. I think the transcoding part is not the issue though. Sometimes, the player starts playing the file, but then crashes and provides the message: "too many errors". I would include the androidtv crash logs, but I couldn't find any related to this time period in /var/log/jellyfin.

What I think is happening around the frequent pauses is that the androidtv player is very bursty, and tries to cache a large chunk every few seconds. It then pauses when whatever chunk it tries to chache fails for some reason. The shield is about a 3 meters away from the AP and get's about 400mbps down from my server consistently (using iperf3).

I can direct play using "Just Player" just fine, no transcoding necessary. I can also play on the jellyfin web using transcoding just fine.
