since the development on OGM (OggDS/OggMux/...) has restarted it's time to put together a small FAQ to give some support for the most popular questions.

Here we go!

01) Where do I get the necessary directshow filters?
A new filterset is released by the radlight team, find it here: http://www.oggmedia.info/. In the current state seeking doesn't jump to keyframes, so for a short time the image might be a little garbled.
You can get them at Tobias' site for now.
The new development will put the binaries and sources to a new sourceforge project most likely.

02) I can't put subtitles in my OGM, OggMux just refuses to work(i.e. with an error message box)!
For muxing in subtitles install the SubTitDS-filters from Tobias' site. Uninstall them when you're done and use Gabest's subtitle filters for playback. The subtitle filters from Tobias seem to have speed issues, resulting in jerky playback sometimes!

03) Well, I did uninstall the SubTitDS-filters (or never had them installed) and playback is jerky
Head over to the ffdshow sourceforge archive and download the latest ffdshow alpha build. Install it and set it to decode divx. The DivX directshow filter has issues which cause these playback troubles, when using ffdshow they're gone.
Some soundcards/drivers produce jerky playback as well. Change from "default waveout device" to "default directsound device" then. Find a small tool which can do that in this thread attached to a post of me.
If that all doesn't help, try setting the output from ieee-float to 16bit wave.

04) When using multiple audio tracks, after switching between them the movie runs at double speed!
Well, there's a serious design flaw in the current OGM splitter filter. Two solutions are possible: install the Morgan Stream Switcher or make sure that you only use the same amount of channels and the same sampling rate for multiple audio tracks in OGM for now!

05) I don't want to blow up the size of my AC3. How do I mux them?
Nic has released a version of OggMux which can do that: http://nic.dnsalias.com/OggMux_Nic.zip . Those changes will be put into the "official" OggMux soon.

Ok, this is just a small starter, I will of course extend this list if there are further known solutions/problems. I need some of your input though as I don't have too much time to search together all problems and solutions/workarounds. Thanks for your support - and have fun with OGM!

Best regards
