Sammy 735 Posted August 27, 2019 Share Posted August 27, 2019 Does this look right? My CPU is hitting 90 C and the utilization is about 50%. Playback on my phone is smooth. Link to comment Share on other sites More sharing options...
Guest asrequested Posted August 27, 2019 Share Posted August 27, 2019 (edited) Looks like you may have subs enabled. Click on the i, what does it tell you? Or look at your stats. Edited August 27, 2019 by Doofus Link to comment Share on other sites More sharing options...

Sammy 735 Posted August 27, 2019 Author Share Posted August 27, 2019 What do the stats tell you?AFAIK, the statistics plug-in was deprecated and replaced with playback reporting. I have not used playback reporting yet so I need a little bit of time to sort it out Karma especially not while I'm trying to drive!

Guest asrequested Posted August 27, 2019 Share Posted August 27, 2019 One thing I find strange. If using the Android mobile app, which uses mpv, if the server is transcoding it should not do anything with the audio, but it does. All audio is transcoded by the CPU, and mpv will handle any audio. I know we say that audio transcoding is an easy process, but when transcoding the video, the audio transcoding actually costs about 10fps (I was testing and comparing results). That can be significant if transcoding is running at around 30fps. When possible, the server should leave the audio alone. It makes no sense to use resources unnecessarily. This is a good example of that. A weak CPU could actually slow down the GPU because it can't keep up. Link to comment Share on other sites More sharing options...

Sammy 735 Posted August 27, 2019 Author Share Posted August 27, 2019 Looking at the transcode log it is apparent that the nVidia GPU is being used but I'm wondering why ffmpeg is still hitting my CPU as shown in the first post. Should it be? Thanks! Link to comment Share on other sites More sharing options...

Guest asrequested Posted August 27, 2019 Share Posted August 27, 2019 Try selecting basic AC3 audio and not EAC3. Link to comment Share on other sites More sharing options...
Guest asrequested Posted August 27, 2019 Share Posted August 27, 2019 And maybe lower the bitrate to something like 4Mb/s Link to comment Share on other sites More sharing options...
Sammy 735 Posted August 27, 2019 Author Share Posted August 27, 2019 I don't see an option to change the audio and the bitrate is set to 4Mbps. Hmm.. Link to comment Share on other sites More sharing options...
Guest asrequested Posted August 28, 2019 Share Posted August 28, 2019 The bitrate is in settings under playback. If you don't have an option to change the audio, that means you only have one audio track. Try a different video. Link to comment Share on other sites More sharing options...
Sammy 735 Posted August 28, 2019 Author Share Posted August 28, 2019 I forced a transcode on a 54Mbps hevc file @ 4Mbps. The GPU is definitely engaged but is at 54% in HWMonitor. This seems high but maybe this is where the hack to increase streams come in handy. Sent from my SM-G960U1 using Tapatalk Link to comment Share on other sites More sharing options...
Guest asrequested Posted August 28, 2019 Share Posted August 28, 2019 (edited) The GPU usage is misleading. Even if it said 100% you could probably still add more. It's the same with my CPU. It hits 100% with a few transcodes, but a bunch more can be added. Edited August 28, 2019 by Doofus Link to comment Share on other sites More sharing options...
Sammy 735 Posted August 28, 2019 Author Share Posted August 28, 2019 I have an update. Rather than copy paste it here, I'll just provide a link. Link to comment Share on other sites More sharing options...
