GOM PLAYER AC3 CODEC MAC UPDATE

This fixed the problem for me in that I can now play my files (H.264 video & AC3 audio in the.mkv container) using QT7 and also export them with the video passed through as is and the audio transcoded to AAC for my Apple TV. Go to System Preferences Perian and in the drop down box next to Audio Output: choose Multi-Channel Output, ignoring the warning which will be displayed.

Further, I am still using the same Perian codec component support installed in July of last year so, at least for me, there does not seem to be a current need to update AC3 playback support. And when I do use AVI files, the content is normally compressed as DivX5/MP3 content.

At this point all I can say is that it seems I can play AC3 and AAC audio via both the QT X and QT 7 players on my Mountain Lion system but cannot confirm whether or not this is also true for XviD/AC3 and/or XviD/MP3 AVI content since these are not file formats I normally use.

In my case, the content is handled as DD Pro Logic II optical output to a decoder attached to my iMac (i.e., I did not make system chages which may or may not be compatible with any particular decoder) and as AC3 DD5.1 'Passthrough' output from all TV devices in my home while I let iTunes distribute the same file to iPhone, iPod, and iPad devices which themselves only support stereo but which can also Air Play 5.1 audio remotely through the TV devices. 5) Since you did not indicate if you had modified app handling of AC3 audio via 'passthrough' to an external decoder, I do not know if you have been messing in your system with the Terminal app or not. 4) Since the Perian codec component package runs in the 32-bit mode, I do not usually try to watch AVI content in the 64-bit QT X Player which seems less compatible with many AVI 'legacy' codecs than the QT 7 Player. (But then my work flow is directed toward the use H.264/AAC/AC3 content in M4V file containers for maximum OS/IOS device compatibility.) 3) This Perian package (v1.2.3) also installed the v1.8 Core Audio A/52 and AC3 Codec Component in my 'Audio/Plug-Ins/Component' folder which is what I assume is currently handlng QT 7 AC3 content if not both QT 7 and QT X. I'm trying to use both QT7 and QTX but both plays avi file without sound. (Don't normally keep multiple language VOB files on my system so I don't know if this is different from Lion OS.). 7) Not sure if this is new or not, but I changed the extension on a VOB file containing AC3 DD5.1 English, AC3 stereo Spanish, and AC3 stereo French audio to an MPEG extension and the file plays the video and all three audio tracks simultaneously but QT 7, as is normal, recognized none of the 'muxed' AC3 audio streams. 6) The QT X player will only open/play an AC3 audio file in an AC3 file container while the QT 7 Player will open/play an AC3 audio file in either an AC3 or MOV file container. 5) An AC3 audio file containing AC3 DD5.1 Perian recommended (L R C LFE Ls Rs) speaker assignment only appears to play correctly in the QT 7 Player.

4) An AC3 audio file containing AC3 DD5.1 default (L C R Ls Rs LFE) speaker assighment only appears to play correctly in the QT X Player.
