Server Version#: 1.40.4.8679-7000 Player Version#: Chrome and Android 10.19.0.1142 During hardware transcoding of a 4K media file my stream stops every 15 seconds and starts buffering. However my synology (DS423+) is only running on 20% of the CPU capacity. Another 4K file has the same issue. Any way to solve this issue? The issue occurs within my home wifi 6 network, but also when i stream on the internet. Connection is not the issue as it’s 1 gbps up and download. ![2](https://global.discourse-cdn.com/plex/original/4X/7/2/e/72e14d05f97ff97e98b0fa91994ee0c94259de0b.jpeg) ![1](https://global.discourse-cdn.com/plex/original/4X/9/5/f/95fbb2f6e2bd1e4c3a40761e0b004010f75430b2.jpeg) \ ---

May I direct you to the update for HW subtitles ? > [@Subtitle Burn-In Improvement Test Build](https://forums.plex.tv/t/subtitle-burn-in-improvement-test-build/884481): > > Hey everyone!

The issue still persist after installing 1.40.6.8820-7000. Also turned off the subtitles, but that doesn’t solve the issue. Found a way to solve the issue. When you set the streaming quality to “maximum” instead of “20 mbps” it solves the issue. You also see some kind of “buffering” bump in the current CPU graph now what is missing when you check the 20 mbps transcoding graph in the previous message. ![2](https://global.discourse-cdn.com/plex/original/4X/c/3/8/c38e489851ae4347b44b36e187099fead816a053.jpeg) ![1](https://global.discourse-cdn.com/plex/original/4X/7/9/4/79496cff0b423316c252b84d23dbb3e069f676e1.jpeg) ---

May I please have the server debug logs which capture this? ---

Those are the Player logs. I request you do the following: 1. Play it again (60-120 seconds) 2. Stop Playback 3. Settings - server - Troubleshooting (lower left of Plex/web) 4. Download Logs 5. It will present a ZIP file to you 6. Save that then upload here for me to review ---

@nl1bzw In your Preferences.xml, Remove `VaapiDriver="i965"` it is no longer applicable. Is your shield’s video playback quality set to original / maximum ? ---

There is no vaapidriver=ï965" in my preferences.xml No it was set to 20 mbit. The issue doesn’t occur when i run it on maximum. ---

@nl1bzw (sorry for delay – had a major interruption) There were some things needing fixing. The switching to the i965 driver on GeminiLake is as it should be. Given the updates to the transcoder for the subtitle-burning build , I would give that a shot first. > [@Subtitle Burn-In Improvement Test Build](https://forums.plex.tv/t/subtitle-burn-in-improvement-test-build/884481): > > Hey everyone!

Nvidia and Intel devices have been improved on Windows systems and Nvidia, Intel, and AMD (assuming no ToneMapping is required) devices have been improved on Linux based systems. Assuming no significant issues are discovered this… Make certain to get the latest build. HW subtitle burning is the biggest help for ApolloLake/GeminiLake models. ---
