    We have fixed an issue that can affect transcoding speed, so please contact us at support [at] conceiva [dot] com and you can try a patch. It may speed up your transcoding in certain situations (depends on original file's formats & transcoded file's formats).

    I installed patch and did new test. First 15gb Avangers version works perfect, fro beginning I got ~500fps, yes five hundreds!!!! CPU usage ~20%, yes only 20%!!!!

    Second I tried Avangers 5Gb version, I got same like yesterday, big cpu usage and ~20fps. Contraband showed yesterdays results too.

    So you need somthing to do for all files what you did for first, of-course, if it possible.

    And one more thing, I checked transcoding folder of Avagers 15gb version, today transcoded file size ~14gb (yesterday ~5gb)

    Hi,
    The 15gb Avagers transcode is fast because the video has been remuxed instead of a full transcode, this is why the transcoded file size is so large. The other files are being fully transcoded instead of being remuxed because either their bitrate or level is higher than the setting in the device profile, if you can send us the ffmpeg information of the Avangers 5Gb version and the Contraband file by right-clicking on each file in Mezzmo and select 'Get FFmpeg Information' and then click 'Copy to Clipboard' and paste the contents into an email to support [at] conceiva [dot] com we can send you a modified device profile to try. Please tell us in the email the device profile that you are currently using so that we can compare the information from the files and make the modifications.

    15gb isn't remuxed, AVAGERS.2012.TRIPLE.BDRip.1080p.h264.AC3.-HQ-ViDEO is HQ video with huge bitrate.

    I think what Peter is saying is that Mezzmo server is remuxing your 15gb Avengers file to make it compatible for your playing on your DLNA device so that's why the fps is so fast. Remuxing will copy any video or audio channels from the original file and place them in a compatible file container. Only the non-compatible channels are fully transcoded.

    Please contact us at support [at] conceiva [dot] com and we may have a patch that can help reduce the requirement for a full transcode (and do a quicker remux instead). In your email to us, please include a set of logs when you try to stream your Blu-ray rip. This will help us pinpoint any bottlenecks in your setup. Turn transcoding on (see http://forum.conceiva.com/showthread...nostic-logging) and restart your Mezzmo server. Connect to Mezzmo server using your WD TV Live and play the Blu-ray rip. After it starts to stutter, stop your Mezzmo server and exit Mezzmo. Zip up all the logs & send them to us at support [at] conceiva [dot] com.

    im thinking of updating my server to 2x cpu's as below would 2x of these be good for transcodeing 1080 on the fly ?

    I'm no CPU expert, but it looks fine to me. I'll let others chip in with more knowledge of CPU models. As mentioned many times on this forum, the general rule is that the more CPU performance & RAM, then the better transcoding performance you will get.

    One thing to consider is getting an Intel CPU with Intel Quick Sync support. The upcoming Mezzmo v5.0 supports Intel Quick Sync hardware encoding & this can give you faster transcoding times when transcoding video. We're just testing this now in our Mezzmo v5.0 Beta testing.
