mp4 with 5.1 AAC audio not playing on xbox 360

[rkneeshaw]

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.

Yes please, I'm happy to test it!

If it doesnt work, can we force Mezzmo to transcode everything to WMV by further editing the profile?

[Paul]

Yes, we can force Mezzmo to transcode everything to WMV (of course it's the slowest transcoding format, so the experience won't be great, unless you've got a really fast CPU).

To try, edit the MicrosoftXBox360.prf (in Notepad) and change:

        <avcontainer id="mov,mp4,m4a,3gp,3g2,mj2" name="mp4_video" encode="0" mimetype="video/mp4" supportschunked="0">
                <video>
                        <format id="mpeg4" encode="0">

                </video>
                <audio>
                        <format id="aac" encode="0">

                        </format>
                </audio>
        </avcontainer>

to:

        <avcontainer id="mov,mp4,m4a,3gp,3g2,mj2" name="h264aac" encode="1" mimetype="video/mp4" format="mp4" supportschunked="0" preferredtranscoded="1">

Also, change

preferredtranscoded="1"

to be

preferredtranscoded="0"

in the ASF container.

After that save the file, restart the server and give it a try. I'd recommend enabling logging before that and then checking the transcoding log for any possible errors and such.

[rkneeshaw]

ok tried that and now instead of just kicking me back to the "file browser" without error on the xbox it actually gives me an error that the format is not supported (69-C00D002F). Maybe that counts for something?

Here is the Transcoder log:

Looks like what you stated before, it cant transcode from 6 channels to 2?

Resampling with input channels greater than 2 unsupported.

Does this mean we are stuck transcoding to WMV?

[Paul]

Hmm, what if you change that to:

Try that and see if it produces a playable result.

If it still doesn't, I'll give it a try here later as well and see if I can make it work.

[rkneeshaw]

Ok this time it produced the same result but a new error code on the xbox: 69-807B0194

Error in the transcoder log looks the same though:

Try this one:

                        <format id="aac" encode="1" codec="aac" preferredtranscoded="1">
                        	<channels>2</channels>

                        </format>

(added 6 channels to AAC encoding basically)

[rkneeshaw]

Check out this guy who had a similar problem:

http://www.activeobjects.no/subsonic...?p=19555#19555

Is it possible to somehow remove the "-ac 2" switch and see what happens?

[Paul]

You can try running it manually by pasting the command line from the log into a DOS command prompt.

Or adjust the profile as per my last post and that'll actually add "-ac 6" in case of 5.1 sound.

Is it the same error?
