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.

@@Waldonnis may have some tips.

 

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

 

Nvidia:

ffmpeg.exe -hide_banner -loglevel info -i test-1080p.mkv -c:v h264_nvenc -c:a copy -crf %crf% -quality quality -b:v 2M -bufsize 16M -maxrate 6M out.ts

CPU:

ffmpeg.exe -hide_banner -loglevel info -i test-1080p.mkv -c:v libx264 -c:a copy -preset %preset% -crf %crf% -quality quality -b:v 2M -bufsize 16M -maxrate 6M out.ts

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.

I'll check it out, in a little while.

 

10-4   you might have to download it again...  see if the .exe loads up and what not..  thx..
