But then GPU and CPU is at almost 100% when encoding 6 profiles at the same time. hwuploadextrahwframes64,formatqsv -c:v h264qsv -b:v 4M -maxrate 4M -b:v. Sure in a scenario with SW decoder + NV encoder I get far more speed. Tho, when decoder is nvdec, quality for lower profiles, from let's 480p and under is really really bad compared to those that are being decoded via SW and encoded via NVENC. ![]() Also i added -y as usual in automation in order to avoid potentially forever hanging ffmpeg, waiting for me to confirm overwrite of the output file.ĭid you manage to get nvenc and qsv running on the same machine at the same time?Īlso, yes, I'm running nvdec, nvenc and qsv on the same machine. I use qsv h264 encoder with ffmpeg (latest build by Zeranoe) on Win7 with media Studio 2017 installed. You don't need a custom build just for utilizing QSV or NVENC, it is contained in every standard build these days. Note that i removed also -loglevel debug just in order to remove noise and also i change the ffmpeg path to the one that comes with ffastrans.
