It decodes in compat stereo mode. I attached fixed decoder to this ticket, it will be interesting if you just run ffmpeg acodec copy command and then compile and run decoder on it .. it may decode to 4 files! But not sure how it all was arranged when it comes to microphones ...? Does camera contain 4 of them? or you were supposed to connect your own array?</div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div>
