[gst-devel] [Soc Project] ASFMux + ASFPayloader

[thiagoss]

First of all, thanks for the reply.

That's a good idea, I thought those features were not needed/used, but
having a longer project focused all around ASF is even better.

The original proposal covered audio, video and tags.

But now that you mention a featureful ASF (and suggest some of features),
the following could be added:

- subtitles
- scripting
- mutual exclusion streams (single, grouped)
- stream prioritization

Additionally, we (or I) might have to hack into asfdemux to add support to
some of those (I don't know if they already work).

Am I forgetting something important?
Also, what media types (audio/video) are most used aside from WMA and WMV?
