    Default Transcoding general questions & Hardware transcoding questions

    I am using a Windows 7 / 64 machine with an i7-4790K cpu @ 4.4 GHz, 32 GB ram and SSD for C:\ ; there is no video card, video is just the on-chip Intel HD Graphics 4600

    The i7-4790k supports Intel's QuickSync hardware decode / code

    I have installed Intel Media SDK 2018 R2

    What version of ffmpeg.exe should I use- 64 bit or 32 bit? I currently have the 64 bit ffmpeg build date 6/5/2019 at 17:29:54 - is this correct?

    When I enable either of the transcode hardware acceleration modes DECODE: Direct3D, ENCODE: Intel QuickSync or both, I get an error message from Windows "ffmpeg has stopped working" when I try to transcode anything. I can then see at least two ffmpeg processes in Windows TaskManager, each using a large amount of CPU. I have to kill those and kill and re-start Mezzmo to get things going again.

    Does hardware acceleration for transcoding actually work in Mezzmo? I can't get it to work. I wonder if there is some kind of setup for ffmpeg I need to correct?

    "Software" transcoding works OK but it causes something like 100% CPU activity on all eight threads, the fans spool up to keep the CPU cool- the Mezzmo server in my closet sounds like a jet engine during transcoding. Seems to me that enabling hardware transcoding would spare the machine this trauma, if it could be made to work.
