Video Stuttering. Possible Bitrate Issue?

[quasar25]

Hello everyone. As the title states, I have an issue where my movie video stutters, specifically on the LG webOS Jellyfin App. I have my Jellyfin application running on a TrueNAS server. I haven't done extensive testing, but so far I haven't had any stuttering issues on my Roku and on my chrome browser. The video stutters are somewhat frequent, usually happening once or twice every few minutes and can last from less than a second up to around 5 seconds (from what I've seen). Audio doesn't have a stuttering issue, presumably because it is a much lower bitrate.

I know that my LG TV's ethernet port only supports up to 100 mbps, but even my highest bitrate movies aren't higher than that. I've had movies at around 60-80 mbps bitrate stutter pretty often even though it shouldn't be an issue. Movies with very low bitrates (think 10-20 mbps) play just fine without stuttering. My question is regarding whether this is an LG Jellyfin app issue or a network bandwidth issue? One thing I thought was interesting is on my TrueNAS dashboard I see outgoing traffic seem to peak out around that 100 mbps cap, even though the movie shouldn't be requiring that. I guess the movie isn't being sent over at a steady rate and likes to swing wildly in network bandwidth usage.

Here is my log if you need it, but I don't see anything that seems out of the ordinary. Just for clarification, only the last movie had any video stuttering.

[TheDreadPirate]

What are your server specs? And can you share your ffmpeg log associated with the LG TV playback?

And is the video stuttering or buffering?

[quasar25]

My servers specs are:

• CPU: Intel® Xeon® E-2176G CPU @ 3.70GHz
  
• Motherboard: SuperMicro MBD-X11SCH-F-O
  
• RAM: 32 GB of Crucial ECC UDIMM PC4-21300 DDR4 2666MHz
  
• OS: Bare metal TrueNAS Scale Electric Eel-24.10.0.2
  
• Jellyfin: Jellyfin for WebOS 10.10.3
  

Here is the ffmpeg log for one of the movies that was having the issue.

...CUT OFF FOR BREVITY   

The log is spliced because it was too long for this post, but the transcode appeared in the same pattern for the rest of the movie, evening out at speed=13x. Regarding whether it's buffering or stuttering, I would say it appears to be stuttering. The audio keeps playing as normal and the video appears to speedily "catch back up" once it's done freezing up. If it was buffering wouldn't there be a loading circle or some sort of indicator?

I re-read your post and noticed the bit about the TV's ethernet port. If your TV is still connected with the ethernet port, switch to WiFi. TV makers seriously skimp on the ethernet controller and they struggle to actually reach 100Mbps (they usually don't). Good WiFi 5+ will be significantly faster.

[quasar25]

Unfortunately, I already tried switching to WiFi and it didn't help things. TrueNAS shows my outgoing bandwidth has higher peaks (200-300 mbps), but the video still stutters, sometimes for longer than with ethernet. Even though my LG TV sits right on top of the cabinet my router is in, I get spotty performance. My WiFi isn't very consistent whenever it comes to bandwidth even before this issue. I have an old AT&T Pace 5268 which I'm pretty sure uses 802.11ac, so it theoretically should be more than capable, but it might just be general network congestion.

[TheDreadPirate]

Just noticed that the video is Dolby Vision 7.6. It sounds like it is trying to software decode the video and isn't able to keep up.

Dolby Vision 7.6 is not well supported outside of bluray players. Your options are to force transcoding, so that Jellyfin will tone map it, or convert it to HDR10.

[quasar25]

I don't think that's the issue. My CPU usage is only about 10% when transcoding happens. Additionally, I have just retested that same movie on my computer browser and on my Roku TV and they both work fine without stutter on both direct and transcoded streams. 

I think it might be something with the webOS app or the LG TV in general maybe. High bitrate movies stutter on both direct stream and higher quality transcoded stream (60 and 80 mbps), so I tried lowering the quality of the movie down to 40 mbps and it seems to mostly stop at that threshold.

One thing I forgot to mention is that when the movie stutters, it seems the whole app does too as the UI becomes unresponsive during the stuttering (clicking over to the pause button, caption button, etc). Sometimes the app even crashes to free up memory, but that's only happened twice and seems rare.

Also my Roku and computer are both connected to WiFi so I guess it wasn't a network congestion issue.

[TheDreadPirate]

I mean on the TV it is software decoding instead of hardware accelerated. Since TV's and streaming devices do not support DV 7.6 in hardware, the TV is trying to play it anyway.

When you are lowering the quality to 40Mbps it is probably triggering a transcode.

The UI becoming unresponsive, to me, backs up the TV trying to play the video anyway even though the platform doesn't support accelerated playback of that format.

[quasar25]

Sorry for the late reply. I've had other 4K movies that use HVEC 10-bit and not Dolby Vision, but still stutter. Here's a snippet of a video codec from a log of an example movie that is high bitrate and stutters.

That video is HDR10.

Code:

ColorSpace":"bt2020nc

But it could still be network congestion if only super high bit rate videos are affected.

Is the TV on the 5Ghz band of your WIFI?
