Hi,
I am running plex media server Version 1.30.1.6562 on a raspberry pi. I have been trying to watch family guy and it goes for a few minutes then i get a message on my roku saying the server is not powerful enough to playback the hvec videos.
on my roku i have the plex app settings of direct stream set to on. direct play I have tried in auto force and disable.
Attached are my logs
Plex Media Server Logs_2023-08-19_21-06-36.zip (3.1 MB)
I have updated my server to Version 1.32.5.7349.
if you have any advice as per my logs it would be greatly appreciated.
You’d have to check and see what that particular model of raspi is capable of in terms of codecs, but as far as I know most systems need to transcode HVEC since it isn’t natively supported in PMS for direct stream. The raspi won’t be nearly powerful enough to transcode HVEC, the client/player would need to support HVEC so PMS doesn’t need to transcode and can direct play the media.
Plex has no ARMv8 HW hardware transcoding support.
When PMS was originally ported to ARMv8, we tested its capabilities.
We found it’s good for for about 20 Mbps of 1080p software transcoding (total throughput)
It can DirectStream (audio transcode only) a few more but DirectPlay is the optimal playback mode.
The Roku has a unique streaming protocol and, as such, often requires more videos be transcoded than other players.
Only the newer players have better compatibility with HEVC (4800-X for example)
Hi Chuck,
Well I updated my plex server on the raspberry pi to Version 1.32.5.7349. Everything plays in my libraries. Just when I start watching 1 tv show do i get buffering errors ever now and then.
can you please take a look at my recent logs that show something going on.
in the past if you might remember i had a hard time playing king of queens they were hevc videos and you had me put direct play to force and they worked after that.
the current videos are of family guy and im not really sure the type of file it is(I think theres a cmd in terminal i can use to determine this.
Nonetheless my logs are attached and it will or should show my buffering error(they are not showing as transcoding errors).
on my roku plex app I have it set as local and remote both to 2Mbps.

be it as i re read your msg earlier should i shut off trancoding on my server. I really dont see why bc my other cideos play just fine. At least since the last time i tried it.

Hello Chuck,
I shut off trancoding on the rp server of plex, so far so good. Will try watching a full episode tommorow and see if it does that buffering every now and then.
When you reply on this forum i get notified by email. can i respond by email too to this thread?
my raspberry pi 4 is a rp 4 model B 4GB of ram with an ARM v 7 processor quad core.
Anyways heres my logs.

Here, you see it transcoding HEVC to H264 .
In a nuthshell “Not going to happen” . The ARMv7 doesn’t come close to transcoding HEVC.
ARMv8 can’t do it either.

Hi Chuck,
Yea last night after i read your message at first i didnt get it. But then i read it backwards and chronigically and i saw the common thread. to disable transcoding.
I did that last night and I watched a full length episode today and everything is fine.
I have been told in other forums in the past to disable trancoding on the pi. I have tried this in the past and it caused more issues.
Thank you very much for the help so far i really appreciate it.
I will let you know if i have any issues going forward. But for now im good.
Have a great day

Goood morning Chuck,
Well everything was working well up until today.
Today I was watching an item, it buffered ok. Then i got an error mshg that it couldnt play the item bc direct play was disabled.
So i set direct play as auto it buffered ok, but got an error msg that no audio detected.
So I set direct play to auto, upon playing the video i got the error that it cannot play the item bc direct play is disabled.
I have tried all different combinations of direct play settings and to no avail.
Clearly when i set it to auto i get a false message that it is disabled.
ohh does direct stream need to be on, bc it was on for all these tests.
please advise
May I please have a set of DEBUG logs which captures the
(Also, which player ?)
Hi Chuck,
Thanks for getting back to me so quickly.
I have a roku streaming stick plus with the plex app. I havetried plaing my videos using direct play in force, auto and disable. I have direct stream enabled. with direct play in force mode it buffers but no audio error message. In disabled mode for direct play it doesnt work. if i set it as direct play as auto i get an error that i still have it disabled so it does not play.
Attached are my logs i hope this suffices.

Hi Chuck,
I think i figured it out.
I was watching other stuff on my plex and everything else requires direct play on auto or force. So I deduced direct play has to stay on so I skipped that one episode as it was corrupt of somesort and everything else plays.
am i right to say if some videos if you have direct play on auto or force and you get an error saying it is disabled that itself is a corrupt copy of the video.
If you have it on Auto then it will do what’s needed but a bad video makes it unpredictable.
If you have it on Force, and you know the content is DirectPlay 100% compatible, then it’s definitely damaged somewhere. The server won’t know (unless you look through all the Scheduled Task logs).
Hi Chuck,
Thanks I think were getting somewhere.
I hav a lot of videos on my plex server on my rp4.
Assuming non of my videos are corrupt. What setting should i have for direct play and direct stream for all my videos to play.
Why do some require direct play as force??
Hi Chuck,
Its ok i remember now.
seems my videos were corrupt which would explain why i got that false error msg saying direct play was disabled when it wasnt.
thank you for your help.
