Hi,
My intel Nuc has an Intel J3455 with a 2251 passmark and it supports hardware encoding.
It’s trying to transcode a video H.264 6,5mbps 1080p but on my tv it keeps buffering. how is ti possible?
It’s transcoding just because i’m watching it with vobsub subtitles, if i disable them, it doesn’t need to transcode and it plays smoothly.
Obviously I have the last version of plex, hardware transcoding is activated and I have plex pass subscription.
Have you tried running the conversion in advance for the film/show/series?
My question is related to the power needed to transcode.
Faqs say a benchmark of 2000 is enough but it doesn’t seem so according to my situation.
I need to understand if there is something wrong or the Faqs are just not correct and I need more power, in that case I would buy a more powerful mini pc for my plex server
Should be enough.
Is the server machine double jobbing?
Does this problem happen with other videos?
Could be a file issue
Keep in mind the 2000 Passmark requirement is an indication.
Depending on the video’s technical specs the transcode might require more power.
Have you configured your server to actually use hw-accelerated streaming?
Also… there’s use cases where the iGPU cannot transcode your media (e.g. if there’s a requirement to burn a subtitle into your video). To help troubleshoot this… can you check the information showing in the “now playing” tile from the Plex dashboard while attempting to play that video and share that information?
It’s written video 1080p h. 264 transcode h.264, audio direct play.
This video has voxsub subtitles and plex transcodes the video only if I activate the subtitles. Without them, if plays directly without transcoding.
Hardware acceleration is ON and plex is the only app on this pc
HW transcoding does not work to burn subtitles into your video. Therefore your server has to rely only on the CPU.
You might try to set the playback quality for that video to 720p to see if the CPU can deal with encoding it in real-time. The reference Passcode score to transcode to 720p/h264 is lower, so this should be working with your CPU.
I don’t know why but now it’s working well and I think it’s doing harware transcoding even if it’s burning vobsub subtitles.
It is… but it’s not burning in the subtitle into your video. Probably this client version is able to directly play those vobsub subtitles.
It’s the same client of yesterday. And the same video.
Also, if it’s not burning the subtitles, why it’s transcoding the video? The client supports h264 and if it turn off subtitles, it stops to transcode and it starts to direct play
