View Full Version : AVI and NSV as Containers.

NSV, using Vp3/theora codec that usually gets used in shoutcast streams is a container (as I understand, I may be wrong) rather than the mechanism.

An AVI that uses the theora codec is well understood by editable programs, where the NSV format is not. What about stripping the container off of the codec?. Then making the new container be NSV compatible?.

For example. I encode an AVI, which is readable and editable with theora. I use a different container. I don't have to re-encode and have more compression loss.

Sort of changing a 1 quart wide mouth mayonnaise jar for a narrow one. Make the lid fit.

The advantage?. An extreme increase in compression speed and no loss from re-encoding the video.

Currently, I make an AVI, then I recompress for no reason (that I can figure) to a different codec.

I usually use Indeo codecs and then turn them into VP3. That sucks. It would be better to use VP3 and "Just change the Jar".

you need an avi demuxer and an nsv muxer.

I guess I was too long winded, but yes.

ffmpeg devs are working (planning?) on nsv (de)muxer, so u'll be able what you tried :D discribe.

btw theora!=vp3, theora original container should/must be ogg, although i think it's possible to make theora in avi with ffdshow vfw

I think my idea is flawed. Most of the editing software will only handle PCM or sometimes MP3 formats. I usually use an older version of Asymetrix Digital video producer to make custom video. That or Virtualdub.

Pardon me for thinking out loud.

Please, put it as a real sig, instead of typing it every time.

Bulk used to be a mild mannered scientist, but then he was exposed to atomic radiation and became:

THE BEAST FROM YUCCA FLATS!.

You can watch the harsh transition of a man who was a great scientist. Then "Bulk" ran into AOL!. Like a nuclear bomb or a mobile made of microwaved AOL disks!.
