    Default mp4 with 5.1 AAC audio not playing on xbox 360

    Hello,

    I'm evaluating mezzmo as my media server, but it doesn't stream my mp4 videos to my xbox 360. This is probably because of the fact that the xbox 360 only supports 2 channel aac audio and my video's are 5.1. I would suspect mezzmo to transcode the audio to 2.0 but that doesn't seem to happen. Can this be added to the xbox 360 profile?

    Thank you.

    Hello,

    Can you please post FFmpeg information about one of those files (in Mezzmo right-click on the file and use the "Get FFmpeg Information" command) - I can then check it against the profile to see what's happening.

    Thank you for your quick reply.
    Here is the ffmpeg information for one of the files that didn't work.

    Thanks for the file info.

    It fails because FFmpeg cannot resample 6 channels to 2 channels - we'll need to find a solution for this. Please send a message to support (at) conceiva (dot) com and once we have a working solution, I'll send you an updated device profile.

    Maybe the trick we did with the WDTV profile would work - transcoding from AAC 5.1 to AC3 5.1? If the Xbox 360 can pass AC3 to the receiver, that would do the trick.

    I'll give that a try as well - thanks for the suggestion.

    Any update on this?

    I've been evaluating tversity but they seem to have the same problem. Does Mezzmo have a solution for those of us with H.264/AAC 5.1 mp4 files and want to stream to xbox 360 without converting all our video files?

    I think that the XBox360 does not support AC3 in an MP4 container at this point. Maybe they'll add it in a future firmware update, but for the time being I don't think it's possible, unfortunately.

    If anyone was successful in playing MP4 files with h264 video and AC3 audio on the XBox, please let me know.

    I thought AC3 was different than AAC?

    Regardless, the main purpose (IMHO) of using a media server rather than file shares is because it will transcode to the proper format for the device. Mezzmo doesnt seem to be doing that properly at this point?

    EDIT: I see where you're coming from, and I agree, I dont think that will work because xbox doesnt support AC3 in a mp4 container. Bottom line we either need mezzmo to resample the 6 channel AAC audio to 2 channel AAC, or transcode the entire stream to something like a WMV or AVI. Can either of those two things be done?

    Yes, currently Mezzmo will transcode to WMV - we tried AVI as well, but it appeared that XBox didn't play some of the AVI files we generated, so WMV is a safer choice (at least for now).

    FFmpeg considers AAC an "experimental" format at this point, so we can encode it, but it's not in the released device profiles. I'll be happy to tell you how to modify the XBox profile to transcode to AAC and you can test and see if it works for you or not.
