View Full Version : Even Lower Overhead for AVI

After allowing to put several MP3-VBR frames, as well as several DTS frames into one chunk in avi-mux gui 1.16.8, the question is of course if this introduces new compatibility issues. I already know that VirtualDubMod doesn't read back files with several MP3VBR frames in one chunk.

For example, a LOTR TTT - Rip with 2xAC3 audio and 1x DTS audio, which had 52 MB overhead as OGM, 7 MB as MKV and 19 MB as AVI, now has 10 MB of overhead as AVI (with 20 DTS frames per chunk).

Especially, I'd like to know if such interleave causes issues with hardware DTS decoders. So if you have a hardware dts decoder, please try if such an interleave causes problems or not, and report about your experience, so that I know if I have to add some warnings :p


EDIT the *first* answer being *totally* off topic is probably a new record. However, if you have a hardware dts decoder, just report about the result here, whatever amount of noise there is in the thread...

Who would put ac3 or dts into ogm btw.? OGM is meant to be a container for ogg vorbis sondtracks and video as well as subtitles. (So compare overhead with ogg vorbis soundtracks if you want to polarise more.)

So for everyone reading this, don't use your car to pass over an ocean, it's simply not _meant_ for doing that.

EDIT: Alex, I can edit my post, too. I didn't fill up your "test please" with "and there was that overhead and here that." So your post started as usual as a trolling attempt, as the "noise" that you describe.

So you acknowledge the fact that OGM is just a technology demonstration to advertise Vorbis ? Not a general purpose container ?

edit: I've been accused of profanity and threatened to be banned for 30 days for saying this.

Do you recommend any specific method to pass DTS frames strait out a SPDIF connector? Also, do you have a sample that I could try?

Does anyone actually post on-topic around here?

Doesn't MPC natively support this? I don't have such a decoder on my own, so I can't try :-(((

Don't we just love the right of free speech? :D

Not when it happens only every 30 days ;)

The only test files I could offer would be short excerpts from LOTR, which would 1) still be large (my webspace is limited) and 2) I'd like to know if offering excerpts of LOTR on a public forum is a good idea...i somehow don't think so

To follow the secondary topic, it's on page 8 (http://www-user.tu-chemnitz.de/~noe/Video-Zeug/containers.pdf) and a bit additional stuff on 13
