Quicktime and Vorbis

[juicemansam]

I was just wondering if anyone knows if it's possible to use Vorbis audio in Quicktime containers. What FourCC does it use? Does it have the same problems as Vorbis/AVI?

No, this is not possible, at least for what I know. Quicktime is a closed format, it is limited to playback in Quicktime Player. Even if it was possible to put a QT file into an ogg container, there is no way to play it back as I don't believe Quicktime's player supports vorbis audio. There is no FourCC IIRC for Quicktime because Quicktime is a container like Ogg is. And I don't believe the reverse is true with Vorbis in Quicktime containers either for the same problem, Quicktime is a closed container, it can only be played in the Quicktime player, which doesn't support Vorbis audio. This will be a possibility to mux Quicktime based codecs into OGM as soon as a DirectShow filter is written to playback Quicktime codecs in regular (non-Quicktime) players... e.g. ZPlayer, MPlayer2, MPlayer Classic etc. So no, Vorbis/Quicktime are incompatible at this point in time because:

1) Quicktime doesn't understand Vorbis
2) Quicktime is limited to playback in Quicktime Player
3) Quicktime can't be played back in regular players
4) No directshow filter exists for Quicktime
5) Muxers, for Quicktime and OGM/Vorbis/OGG, don't handle each other.

Well, i heard Vorbis can be used in MP4 now for streaming via RTP protocol ..

The FourCC I meant was for the Vorbis audio, like '.mp3' is for MP3's in the Quicktime container.

Here's why I was interested:

I prefer a GNU/Linux environment, which has Quicktime support via OpenQuicktime.
There are reference documents on the Quicktime 6 API and the Quicktime File Format.
It would be a good alternative (I think) since the Quicktime File Format supports various the MPEG video formats and MP3 audio format.
Since only the Quicktime container will be used with DivX(or XviD)/MP3 and not the Quicktime specific audio/video codecs, it shouldn't be to hard to implement a filter, would it?
Besides, Quicktime was chosen as a model over other formats for the MP4 container because of its better features over other formats.

Well, thanks for the info, and any other new info.

That's not true. At least if you mean, that you can't play QT movies in Windows Media Player.
WMP is able to read the QT container an to play the movies, if the codecs are installed. Well, this is the case for Indeo 3 and Cinepack.

If you're going to use Divx or XVID, OGM is a much better way to go. And as Christian said, mplayer is a very good player to use for this format.

@ KAMiKAZOW:
Well, yes, for very simple QT movies such as those codecs that amateur makers have access to will work in WMP. However, modern codecs (e.g. the ones that Quicktime.com uses in trailers etc, e.g. Sorenson) will not work in WMP as the codecs AFAIK are not available for download to use in WMP etc. I may be wrong though. I do not use Quicktime much as it's much harder to make movies with it and much better formats are being worked on that are open source (OGM, MCF, etc) and as Quicktime is a proprietory format, most people (e.g. the people on this forum) use the codecs more common to us, divx, xvid, etc. Sorry about the rambling, but to get back to the reply. Yes it can handle Indeo 3 and Cinepack as directshow decompressors exist for these and not for Sorenson, etc (at least that I know of...someone can feel free to correct me).
