(Have you seen VLC available in the Mac App Store? No, for that exact reason).įor other blu-ray player programs, they would've either licensed it to only play the audio (more about that below), or they would have used the same "free"* codec as VLC.įor someone like BM to put Dolby support into their program would require a hefty licensing fee as they would need to add support to read (one licence), add support to edit the audio (another licence fee) and to export (because people would get pissy if they couldn't export in it either, adding another fee on top). You'll notice that VLC for the iPhone/iPad was removed from the App Store a while back with no explanation, until just recently when it was placed back on the App Store - without AC-3 support.ĭolby contacted Apple saying that they were essentially using the codec without the rights to do it, so Apple pulled it till it was sorted out.

And what are the chances of that?Ī simple matter - support for.
mts files with sound without difficulty - and even standalone blu-ray players which play. If that were true, then free software like vlc Media Player - which plays.

Once you have the AC3 decoder the audio will play as normal. On PC you can get a windows AC3 codec free online, not sure about the MAC.
You are on the right track with the FFMPEG command.MTS is not a codec it is a container.
