Ogg video

never used it before but check here for some top tips

or some more googling came up with this :

Playing .ogm and .mkv files

These two containers are probably a bit of a mystery to most regular users. Unlike .mov, .rm and .wmv they are not associated with a particular player. The reason for this is that, like .avi, Ogg Media and Matroska are containers for video and audio streams. As containers they have all kinds of features - the Ogg Media container was developed to find a suitable container for using the very popular ogg audio format with video streams (something that .avi will never be able to fully support). The mkv format was developed from scratch to try and accommodate many advanced features and more video and audio formats than any other container to date.

To play files with these containers you will need to use MPlayerOSX or VLC which both support these containers. It is possible, however, that you may find it difficult to decode *some* .mkvs with these players because Matroska can actually be used for storing closed proprietary codecs like Real Video.

now all it needs is ipod support, and attention.

well, on second thought, why do we really need another format? we wouldn't be saving that much disk space.

Agreed and i have to say h.264 is simply amazing format in terms of file size to quality ratio. In many ways it seems better then all those .avi files divx and xvid and the like. Only problem is it takes more or less forever to encode stuff with it unless you have a top of the line machine.

Playing and converting OGG files with QuickTime

Yes, why DO we need another format? Apple could have used OGG and FLAC (lossless) rather than making their own DRM-protection on AAC and developing their own Apple Lossless format. But still, that's what lock-in is all about. Microsoft does it with office formats, Apple does it with audio and video formats.

As to the original question about converting OGG to another format, you can check out the QuickTime OGG Vorbis component at http://qtcomponents.sourceforge.net/ (a bit out of date and only supporting QuickTime 6.0.2 or there's a newer version at http://www.xiph.org/quicktime/) but if you have QuickTime 6 Pro you should be able to then convert the file to another QuickTime supported format or maybe (maybe!) load the OGG into iMovie and save it out as another format.

well, thanks to the links to those quicktime components, I can now import my .OGM video files into QT, but all I get is the audio.

So, I'm halfway there.

This is tough. I just want to convert these .OGM video's into .AVI's so I can burn them as DVD discs in Toast, iDVD ect..

I've been struggling with this for months now with no results. I've tried, FFmpegX, a command line tool, Compressor, iDVD, iMovie, and now these plug in components.

Ugh.

Thanks for your tips.

Wow do FFmpegX didn't work for you i have never thrown a format at the program that it wasn't able to convert. Then again i have never used ogg video files in my life so eh.

Now, now first of all i dont think apple really has much choice with having to come up with a drm scheme the record companies never would have let apple sell the music with out it. And the acc format is not one apple them selves developed its industry wide accepted standard format (mpeg 4). Sure apple lossless i suppose we could have done with out. BTW im not at all familiar with the ogg format how dose it compare file size to apple lossless. Do wish tho itunes would just support all of the formats out there with exception of wma, what an awful format.

Checkout the source of al thing theora related.

Is there any kind of commercial or free app that can convert a .ogg or .ogm video to a quicktime readable format?

Or is there a codec for quicktime that will allow .ogg or .ogm video to play and save in quicktime?

Both ogg and quicktime are "containers" that can contain audio and video that is encoded using any of several codecs. If you have video data inside an ogg container file it is most likely encoded using the "theora" codec and the audio is likery "vorbis" The place to look for software that can read ogg/theora is at "www.theora.org" look at "ffmpeg2theora" the latest version wil read ogg/theora. You will find other software there to

What's the deal with "ogg" and why do we need it? t's about the only truely free set of file formats. others all seem to be either owned my some company or use patented technology. ogg is free both as in "free bear" and "free speech". Not much else is.

Have you tried VLC?

It can open OGG files, and can export in to a variety of formats...

(Unfortunately, I can't find any OGG video files in a quick search, so I can't test it properly right now, but it did take an H.264 and export it into MPEG-1.)

P.S. Thanks! I just discovered that it can also de-multiplex 'transport stream' MPEG-1 files! (Such as the kind Sony digital still cameras produce, that iMovie can't use, and QuickTime Pro thinks have no audio track when exporting.)

How do you export from VLC ???? I had no idea it could do that.....if you solved my issue with something that simple...I will feel very stupid...*runs off to test theory..*



^^ Ok I tried it, and I still have no clue how to export in VLC.....:^^

It's well hidden.... (It's not really meant to transcode one format to another, they even warn you that's not what it's meant for, but it works.)

Open your ogg file in VLC
File -> Streaming/Exporting Wizard (Command Shift W)
Select 'Transcode/Save to File', click 'Next'
Select 'Existing playlist item', and select your open file from the list. (Technically, you could choose 'Select a stream, then use the 'Choose' button to select a file that isn't already open if you felt like it,) then click Next
Check off both 'Transcode Video' and 'Transcode Audio', and select your output formats and bitrates. (Yeah, it's kind of limited, but it does have Toast supported MPEG-1 or MPEG-4 in there.) Click Next
Choose an 'Encapsulation format' (it should pick one by default that is appropriate for the output formats you selected, but double check to be sure. Click next.
Click 'Choose' to select a folder to output to and type in a name, click next.
Confirm the settings. Click Finish.
Wait for your file to transcode itself.

Yeah, get VLC version 0.8.4a if you can.

Will do.

Many thanks

^^yup, now I see it..^^

heh, sorry about that. When I got the new Mac, I had to redownload it, so it didn't even dawn on me that it was a new feature. (Heck, I honestly wasn't sure if VLC could do it, I just decided to open it up and see if it had an export function... I suppose it was pure luck that I happened to be doing it on the latest version.)

It's not the most elegant solution, but if you can play the videos then Snapz Pro X would do the job.

I ran into the same problem tonight, and solved it thanks to this thread.

VLC 0.8.4:
-File menu: Streaming/Export Wizard
__Save to file
__Select file
__Transcode video: MPEG-1, bitrate as desired
__Transcode audio: MPEG Audio, bitrate as desired
__Encapsulation format: MPEG 1
__Export file

ffmpegX 0.0.9v:
-Drag exported mpg from VLC to the ffmpeg window
-encode as desired

I thought I could help some more. Sadly, I don't have any .ogm files on hand.
