<div>I do indeed have a test track.</div>

<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">I wrote code for 0.22 to re-order the AAC channel but I didn't put it<br>in for the following reasons:<br>
1- ffmpeg was supposed to have it fixed and the ffmpeg resync would<br>have made the fix available to mythtv<br></blockquote>

<div>I am running Mythbuntu 9.10 with the mythtv daily builds for .23. It is very possible that this was fixed by ffmpeg but it is not included the Ubuntu 9.10 repository.</div>

<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">2- There are two very different ways AAC audio can be decoded in<br>mythtv. Using libfaad (which seems to be the default with many<br>
distributions) or using ffmpeg build-in decoder. Both of them are<br>using different channel ordering (all of them wrong).<br>Originally ffmpeg used to present the channel order in the way it was<br>stored in the format; like<br>
AC3: LFE L C R SL SR<br>WAV: L R C LFE SL SR<br>AAC: C L R SL SR LFE<br><br>Then they changed to always output the same ordering for all format except AAC..<br><br></blockquote>

<div>Is there a way to determine what method my distro is using? Is it simple to change manually?</div>

<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">MythTV and the new audio code introduced for 0.23 expect the channel<br>order to be the same for all format...<br>
<br>Re-ordering the channels isn't too complicated ; it's a matter of<br>doing the right re-order according to the right format *and* the<br>library used for the decoding...<br><br>If you have a 5.1 AAC test track, I can work on this ASAP and provide<br>
a fix in time for 0.23 ...<br><br></blockquote>

<div>I do indeed have a test video... I cannot promise that it is correct but it does go through and say "left channel", "right channel".... Of course mine come out on all the wrong speakers.</div>
<div> </div>
<div>If you know of a test video that you trust, please link to it and I can use it for any testing you require.</div>
