Spring Update for Xbox 360 Adds MPEG-4 Decode

Spring Update
for Xbox 360
| Among the new features to the Xbox 360 with the Spring
Update is this little jewel below.

  • H.264 video support: Up to 10 Mbps, Baseline, Main, and High
    (up to level 4.1) Profiles with 2 channel AAC LC and Main Profiles.
  • Added MPEG-4 Part 2 video support: Up to 5 Mbps, Simple
    Profile with 2 channel AAC LC and Main Profiles.

The question now is does it apply just to the Dashboard or does it also apply to Media Center Extender functions?

Notes: DivX and XviD are MPEG-4 Part 2 ASP.  According to the announced support, they are not supported.  It also doesn’t say if AVI containers are supported.  There is a lot unanswered at this point about the support, but considering audio support is marked for AAC I assuming that it only supports MP4 containers (meaning not AVI).

Edit: Confirmed that it does not apply to Media Center Extender of the Xbox 360.

Update: Microsoft updated the page.  It used to say H.264 at 15 Mbps, and MPEG-4 at 8 Mbps.  It now says 10 Mbps, and 5 Mbps respectively.

  1. I would wager that it would be the dashboard only at this point.

    If they were to update the Xbox 360 Extender bits so that this new decoding functionality could be used, they’d have to update the .xex file that gets run from either the Xbox 360 hard drive or uploaded from the user’s computer everytime an Extender session is used (so that it knows to use those new codecs).

    Hopefully, now that they have done this work on the dashboard side, the Media Center team can use the same technology in a future release (I doubt they would add it into an existing release).

  2. OK,
    Guess I don’t see WHY they would add this functionality. What good does this do for the system?

  3. Anyone know if they’re going to start supporting directories within the Dashboard, or will we still get the huge almost useless list of video files when we browse videos?

    If you read through the site that Chris linked to, one of the other added features is

    “Show folder hierarchy for video content played from all devices.”

    Is that what you are looking for?
