pir8radio 1289 Posted February 9, 2019 Share Posted February 9, 2019 I'm trying to write my own ffmpeg benchmark, I just suck at ffmpeg lol.... I want to convert an .mkv from whatever bitrate to 1080p 4mbps. I will be using emby's version of ffmpeg, i want this string as close to what emby would use to convert the same media. I would like to auto detect HW acceleration if possible, otherwise i would need a CPU example and a HWacel version... can someone help me out? assume ffmpeg, the test file "test-1080p.mkv" and any output files will be in the same directory.

pir8radio 1289 Posted February 10, 2019 Author Share Posted February 10, 2019 (edited) well.... here is what i threw together real quick... @ can you test? all i have so far is CPU and Nvidia tests, again i just threw it together, it needs lots of work lol embyBenchmark.zip Edited February 10, 2019 by pir8radio Link to comment Share on other sites More sharing options...

Thanks, here is what I'm using for an initial test, but again i would like it to resemble closer to what emby does..

Guest asrequested Posted February 10, 2019 Share Posted February 10, 2019 What are you looking for? The frame rate of the transcode? Link to comment Share on other sites More sharing options...
pir8radio 1289 Posted February 10, 2019 Author Share Posted February 10, 2019 What are you looking for? The frame rate of the transcode? just if the interface works, menu selections, test output file... The goal will be to output a rough guesstimate of approximate concurrent emby streams your hardware will support.. not there yet. Link to comment Share on other sites More sharing options...
