Hi! I understand you're experiencing high dropped frames and a frame rate of 0.00 when streaming with the UHF app on your iPhone running iOS 19.0. Let's work through a few things to pinpoint and fix the issue.

First, can you share a bit more about your setup and usage?
- Are you streaming over Wi-Fi or cellular data?
- Have you noticed this happening consistently or only at certain times?
- Have you tried streaming on another network or device to compare?
- Are you using any other apps heavily while streaming?

Meanwhile, here are some initial steps to try, tailored for iOS streaming:

1. Check Network Connection:
Streaming needs a stable internet connection. Try switching from Wi-Fi to cellular or vice versa. If possible, use a Wi-Fi network on a 5 GHz band for better performance.

2. Close Background Apps:
Double-click the Home button or swipe up and close other apps running in the background to free up system resources.

3. Restart the Device:
Sometimes a simple reboot clears temporary glitches affecting performance.

4. Ensure UHF App Is Updated:
Check the App Store and update to the latest version of UHF - updates may include fixes for streaming performance.

5. Lower Stream Quality Settings in UHF App:
If available, reduce resolution or bitrate settings in the app's streaming options to lessen data demands.

6. Check for iOS Updates:
You're on iOS 19.0, which is current as of your info. If any minor updates or patches are available, apply those.

If these don’t improve the dropped frames and frame rate, the issue might be related to how the app handles encoding or network fluctuations. Some users have had success enabling adaptive bitrate or dynamic bitrate streaming options if your app supports it. Unfortunately, UHF app specifics on this are limited.

Also, dropped frames at 0.00 fps suggest the stream isn’t processing frames successfully, which can hint at network congestion or app-level bugs.

Could you try the above and let me know which steps you already tried or if the problem persists? Then, I can guide you into more advanced checks or settings.

Are you able to share any error messages or logs from the app during streaming? That could also help narrow down the cause.

I am running on Apple tv

Thanks for letting me know you're using an Apple TV. That adds an important detail! To start, which Apple TV model and tvOS version are you running? For example, Apple TV 4K with tvOS 17.0 or later is recommended for UHF app compatibility.

From what I’ve gathered, the UHF app requires at least tvOS 17.0 on Apple TV to work properly. Users on earlier versions or other Apple TV models sometimes report buffering, dropped frames, or even blank screens when launching the app3 2.

Here’s a step-by-step approach for Apple TV:

1. Verify tvOS Version:
On Apple TV, go to Settings > System > Software Updates, and check if you have tvOS 17.0 or newer. If not, update the system.

2. Update the UHF App:
Open the App Store on Apple TV and ensure the UHF app is updated to its latest version.

3. Restart Apple TV:
Go to Settings > System > Restart to reboot the entire device.

4. Close Other Apps:
Double-click the TV remote's Home button to view open apps and swipe up on apps to close them. This frees up memory and reduces streaming interference.

5. Network Check:
Streaming on Apple TV benefits a lot from a stable, high-speed network, preferably wired Ethernet or 5 GHz Wi-Fi. Run a speed test in Settings > Network if available.

6. Reinstall UHF App:
If issues persist, try deleting the UHF app and reinstalling it from the App Store. This can clear potential corrupt files.

If after these steps the dropped frames continue or frame rate stays at 0.00, it might be an app-specific compatibility or streaming server issue. Some users have reported similar buffering and frame drops, sometimes linked to UHF app performance on Apple TV 4K models in forums1.

Could you also share if the problem happens with all streams or just particular channels or playlists? That info helps determine if it’s the app, network, or source causing trouble.

Let me know what tvOS version you have and if you tried any of these steps already! I’m here to find a smooth streaming fix for you.

I am running tvOS 26 on Apple TV a1625

Thanks for sharing that you’re on Apple TV model A1625 running tvOS 26. That’s helpful to know!

The A1625 is the Apple TV 4K (1st generation) model. According to Apple and developer info, tvOS 26 is compatible with your Apple TV 4K (1st gen) model. So your device and OS version are supported by the latest Apple TV software updates3 9.

Regarding the UHF app, it officially requires at least tvOS 17.0 or later on Apple TV, so tvOS 26 falls well within the supported range1. However, there haven’t been public notes or reports confirming full compatibility of UHF specifically tested on tvOS 26 yet.

Since you are experiencing very high dropped frames and 0.00 fps frame rate, here’s how I suggest proceeding with this specific setup:

1. Restart Apple TV — A fresh reboot ensures any background issues or resource glitches are cleared.

2. Update UHF App — Verify you have the absolute latest version from the App Store on your Apple TV. An app update might include critical fixes or improvements for tvOS 26 compatibility.

3. Test Network Stability — High dropped frames often correlate with network issues, especially if streaming resolution is high. Use Ethernet if possible or a strong 5 GHz Wi-Fi.

4. Check Stream Source — Try some different channels, streams, or playlists to determine if the problem is across the board or isolated to certain feeds.

5. Reinstall UHF App — Delete and reinstall the app to clear any possible corrupted data or settings affecting playback.

6. Contact UHF Support or Monitor Forums — Since tvOS 26 is quite new, there might be emerging issues or patches related specifically to that OS version. Checking community forums or raising the issue with UHF developers could get you tailored assistance or timeline for fixes.

If the problem persists after these steps, it’s likely an app-level or streaming server compatibility issue with tvOS 26 on Apple TV model A1625. Currently, I don’t have reports confirming perfect UHF operation on this OS and device combo, so close monitoring and updates will be key.

Would you like me to guide you through any of these steps in more detail? Also, did you by chance try any of these already?

Are you satisfied with this direction to resolve your streaming frame drops?

Streaming on the UHF app on my Mac Studio is perfect, streaming on my Apple TV stutters like crazy

Thanks for clarifying that streaming on your Mac Studio is working perfectly while you have serious stuttering issues on your Apple TV. That definitely helps narrow things down.

Here’s what’s likely going on and how to approach it:

1. Device Performance and Streaming Handling:
Your Mac Studio is a powerful machine that can easily handle high-bitrate streams with strong decoding and buffering capabilities. Apple TV 4K (model A1625) is capable, but it’s more limited in terms of CPU and memory resources compared to your Mac Studio, which might lead to stuttering if streams are very demanding or if the app isn’t fully optimized for tvOS 26 on that model.

2. UHF App Optimization Differences:
The UHF app is designed for multiple platforms, but there are ongoing reports from other Apple TV users of random buffering and stuttering issues that seem to be related to how the app streams or buffers video on Apple TV compared to macOS1. Users note smooth playback on Mac but spotty streaming on Apple TV.

3. Network Differences:
Even with the same network, Apple TV’s Wi-Fi vs Mac’s Ethernet or stronger Wi-Fi connection can cause differences in streaming quality. Confirm whether the Mac Studio is on a wired connection and Apple TV is on Wi-Fi; if so, try connecting Apple TV via Ethernet for a steadier stream.

4. App Version and Device Resources:
Make sure the UHF app on Apple TV is the latest. Also, force-closing and reinstalling the app can address potential corruption or outdated cached data affecting playback.

### Recommendations for smoother streaming on Apple TV:
- Switch Apple TV to a wired Ethernet connection if possible.
- Close other apps running on Apple TV to free resources.
- Lower the streaming quality settings inside UHF app on Apple TV, if the app allows.
- Reinstall the UHF app on Apple TV to clear any corrupted data.
- Keep an eye on any UHF app updates that mention improvements for Apple TV performance.
- Monitor network performance to ensure the Apple TV has a solid connection.

If these steps don’t fix the stuttering, this might be a limitation of the Apple TV device/app combo compared to the Mac Studio’s superior hardware and software optimization. You could also check community forums and reach out to UHF support to see if a fix or update is planned.

Does this sound like what you’re experiencing? Would you like guidance on any particular step?

Are you satisfied with this explanation and the suggested troubleshooting?

I tried everything and it’s still stuttering

Thanks for letting me know you’ve tried all the usual steps and the stuttering on Apple TV still persists. Since the problem continues even after app updates, restarts, network checks, and reinstallations, this could point to a deeper issue possibly involving the app's compatibility with your specific Apple TV model or tvOS 26.

At this point, here are a couple of options to consider:

1. Contact UHF App Support:
Reach out directly to the UHF app developers or support team. They might have insight on this persistent stuttering issue on Apple TV 4K (1st gen) with tvOS 26 and could provide a patch or workaround.

2. Try Alternative Apps:
If you need a smooth streaming experience on Apple TV right away, consider testing other IPTV or streaming apps compatible with Apple TV. This can confirm if the issue is unique to UHF or related to network/device factors.

3. Use AirPlay from Mac Studio:
Since streaming works perfectly on your Mac Studio, you might temporarily use AirPlay to mirror or send the stream from Mac to Apple TV until an UHF fix arrives.
<br4. Monitor for Updates:
Keep an eye on UHF app updates and tvOS patches, as a future release might resolve compatibility or performance problems.

Unfortunately, without specific error logs or internal app diagnostics, I don’t have a direct fix for this persistent issue. Let me know if you want help drafting a detailed message to UHF support or have any other questions!
