really hard to tell from that block of error messages but it looks like either: 1. There is a system library conflict (Error relocating) -or- 2. The card isn’t supported by the drivers (2017 GPU??) – what is the media ? -or- 3. The transcoder regression is impacting AMD as well. -or- 4. you have HDR tone mapping enabled on the AMD – (AMD is SDR only at present) If you wish, you can quick try this as it’s known to work. > **[plexmediaserver\_1.32.5.7349-8f4248874\_amd64.deb](https://drive.google.com/file/d/1wq35oWVL39BzQQs9mNiL-lMNsIIDBMvY/view?usp=sharing)** > > Google Drive file. ---

Thank you Chuck, but you should read my msg more carefully. Here’s my reply: 1. No, I even tried to delete the .so lib and the soft link in the cache, but after PMS restarted there is an exactly same .so file. 2. AMD RX 550, I mentioned before. 3. … 4. No, just H264 SDR 5. 1.32.5 works, but as I mentioned, Android client is disfunctional with this version. ---

I don’t know if you’re aware yet. 1. We’ve reverted PMS 1.32.6 and 1.32.7 due to flaws we missed. (HW transcoding fails for most users) 2. 1.32.5.7349 is now public Which “Android client” as there are several; Android TV (Tv sets), Android mobile/tablet, Nvidia Shield. ---

I saw that, so I will wait for the next beta. For the android client issue with PMS 1.32.5, see the related thread > Blockquote > [Android APP No Longer Starts to Play any Video After PMS Updated to 1.32.5.xxxx](https://forums.plex.tv/t/android-app-no-longer-starts-to-play-any-video-after-pms-updated-to-1-32-5-xxxx/848467/1) and I guess the below fix in PMS 1.32.7 is for this issue: - (Transcoding) Some HW encoded video would not play on Android (#14384) ---

As soon as we base PMS resolved (almost ready). we will reapply the fixes which would be in PMS 1.32.6 and 1.32.7 ---

@Shea-Yone Play with Plex/web. 1. It’s the most basic player 2. If everything works on Plex/web ( transcoding, tonemapping ) we’re good. Saying “Android client” can be: Android TV, Android phone, Android tablet, Android set top box (nvidia shield, etc). Like saying “Apple client is dysfunctional” … not specific enough. We’ll make another player thread if need be ---

I have provided enough contexts for you if you read the info above carefully. “Android client is disfunctional” means if hardware transcoding is enabled, android client cannot play any video and only with android client, all other platform clients are OK. And this issue was confirmed and replicated on my server by your team members @sixones. And he said: > I’ve filled the issue with the server team, even though its only a problem on Android, it seems the transcoded video is corrupt and theres not much we can do to solve that on the client. > Thanks . the server team think they know what the problem is, and they are looking into it. As I said, I guess the fix below in PMS 1.32.7 is for this issue: > (Transcoding) Some HW encoded video would not play on Android (#14384) So, please review this issue with your coworkers.

You have ASS subtitles in the video file. ```auto -codec:2 ass ``` 1. ASS subtitle conversion is not very CPU efficient in FFMPEG. 2. Audio is being converted to OPUS ```auto -codec:1 libopus -b:1 193k ``` 1. You state 60% CPU utilization. 2. In “top”, 60% CPU utilization is 60% of a single thread. The Xeon E3-1230 v2. has 4 cores / 8 threads yieldinging 5088 passmarks. Ref: [PassMark - Intel Xeon E3-1230 @ 3.20GHz - Price performance comparison](https://www.cpubenchmark.net/cpu.php?cpu=Intel+Xeon+E3-1230+%40+3.20GHz&id=1199) Are you stating that 60% CPU utilization on this CPU. where 800% utilization being displayed is what Linux will show if the CPU is fully consumed is how you define “Not working” ? Also, we have one item to we ask you to test. Specifically , PMS 1.32.1 and see if the behavior is the same. ---

@ChuckPa Thanks for your work. The CPU loading is OK (\<10%) with **1.32.6.7521** , even with ass subtitles. This is not a problem now. The problem is **Android client cannot start to play any movie (stuck at loading) with hw transcoding**, and only Android client, all other clients are OK, such as Web/Windows/Mac/iOS. This problem is started from 1.32.5, since that version starts to support amd gpu hw transcoding on linux. I saw **1.32.6.7521** merged #14384, but it’s no difference with \*\* 1.32.5 \*\* > (Transcoding) Some HW encoded video would not play on Android (#14384) Please, Chuck , keep up with my steps 😃 ---

Thank you. I will pass this to both the transcoder engineer and the Android engineer. I know the change which happened and will let them resolve it. Please capture the fault and download the player logs. The android engineer will want to see and confirm.
