Burrito78 15 Posted May 30, 2018 Share Posted May 30, 2018 Hi there, normally i'm transcoding Blu-ray MKV rips at around 50fps with 30% CPU using VAAPI on DS416play. But "Family Guy presents: Blue Harvest" is only transcoding at 18fps (40% CPU) and therefore transcoding isn't fast enough for playback. Maybe the logs will show any hints why its so slow. Best regards, Burrito78 server.txt ffmpeg-transcode-28b51636-6d24-475a-b079-4e25d14eabac.txt mediainfo.txt Link to comment Share on other sites More sharing options...
Solution Luke 37063 Posted May 30, 2018 Solution Share Posted May 30, 2018 This is burning in subtitles which can be painful. Try turning them off. 1 Link to comment Share on other sites More sharing options...
Burrito78 15 Posted May 30, 2018 Author Share Posted May 30, 2018 Hi Luke! That was the problem! Turned them off and back to 51fps. Thanks for your fast help! Link to comment Share on other sites More sharing options...
Burrito78 15 Posted May 30, 2018 Author Share Posted May 30, 2018 Just a thought: Wouldn't it be nice if the Web-UI could overlay the subtitles? Link to comment Share on other sites More sharing options...
Luke 37063 Posted May 30, 2018 Share Posted May 30, 2018 We already do, when the browser supports the subtitle format. Link to comment Share on other sites More sharing options...
Burrito78 15 Posted May 30, 2018 Author Share Posted May 30, 2018 Nice to know! But in this case it doesn't matter if i use Safari or Chrome, results are the same. Why would transcoding be so slow when CPU is only at 40% though? Link to comment Share on other sites More sharing options...
Luke 37063 Posted May 30, 2018 Share Posted May 30, 2018 But in this case it doesn't matter if i use Safari or Chrome, results are the same. In this case that is expected. It looks like you have gpu features enabled so it would appear that the cpu is not the bottleneck, so that is most likely why it's only at 40%.
