    I have been a happy user of Mediatomb for the past 2 years. It's been running on a Shuttle K45 with a 1.8 GHz Celeron, 1GB
    RAM, and Ubuntu 8.04, and displays on my DirectTV HR-22. Unfortunately my Shuttle's motherboard just died. I'm thinking
    about replacing it with an Intel D510 dual-core Atom-based system. I see lots of posts on this forum about performance on
    DNS-323 (ARM) but I prefer the Intel architecture to easily use other applications.

    Can anyone tell me if they have successfully used Mediatomb on an Intel Atom to do the following:
    a) Display JPGE photos (I hope that should be easy)
    b) Play transcoded MP4/AAC (iTunes) audio
    c) Play transcoded MP4/H.264 (iTunes) video
    I am using the transcoding scripts in the wiki; nothing too fancy.

    I accidently posted this message first on the "open discussion" forum, but meant to post it here. Sorry for the duplicate post.

    Thanks for the help!

    Dave

    Since no one answered my question I will do it myself:-)

    I built a replacement system using a Gigabyte GA-D510UD motherboard which uses a dual-code Intel Atom D510. When playing mp4 video using ffmpeg, the CPU utilization is about 45%. When playing mp4 audio using vlc, the CPU utilization is about 4%.

    So I think the dual-core Atom is a great platform for Mediatomb.

    Thanks for all the great work you guys have done!

    Saying mp4 isn't enough since there are so many levels to mp4 videos.

    Do you know what profile and/or level of mp4 is being served?
    Are you just serving mp4s or are you transcoding them?
