View Full Version : High util remains after file is stopped-ffmpeg.exe still runs

Hi,
Trying out the trial version again (2.2.0.0) because its the only DLNA server I can find that will play/transcode .wtv files recorded on a WIN 7 machine (PS3MS, Serviio and TVersity all fail.) ;)

Using it through the native DLNA player of my Samsung B series TV-it plays ok, no problems there but when I look at the PC from where the file is being hosted on my network, CPU util remains at 70% after I kill the file and/or turn off the TV. I notice that ffmpeg is still running.I kill this process and the util drop back to normal.It appears that Mezzmo does not shut down this process? I have left it for about 10 mins and it is still running-if this was to continue I would imagine my PC would eventually run out of grunt, if I was opening file after file.

I attach the logs for your info-I'll be up front and would like to buy Mezzmo but this puts me off, plus the fact that you dont support Internet streaming (ala TVersity for the BBI player here in the UK) but thought it best you know what I'm seeing.

cheers

Have you unchecked the option to finish transcoding files in CPU idle time? If this option remains selected, Mezzmo will continue to have ffmpeg run in order to complete transcoding of the file so it can be accessed in the future without transcoding. This will generally result in high processor utilization while it completes the transcode, which very easily could exceed the 10 minutes you noted.

Nope-I havent. Didn't know such an option existed. UPDATE-I found it and unchecked it-the ffmpeg stops, when I stop the file,which is great.One other thing I noticed is that with this option unchecked, the overall util seems lower as well-but maybe that's just me. BTW, does Mezzmo transcode .wtv files or are they passed straight through.Looks like it as the util doesn't change, whereas with the "old" dvr-ms files, util pops up to 70%, which I guess is the transcoding.
Another reason to move over to WIN7 ;-)

WTV files are transcoded for pretty much every device, since none of those we tested support this format natively, but in most cases they can be simply remuxed into an mpeg container and that's why you'll see less CPU used.
