Multimedia, AV "When I started working on a no-DRM, open-standards-based solution for distributing high-definition video on fixed media ('Lib-Ray'), I naturally thought of Theora, because it was developed as a free software project. Several people have suggested, though, that the VP8 codec would be a better fit for my application. This month, I've finally gotten the necessary vpxtools and mkvtoolnix packages installed on my Debian system, and so I'm having a first-look at VP8. The results are very promising, though the tools are somewhat finicky."

"I'm currently working on the subtitle format (going to be SRT now, in separate files)


This I want some more clarification on: is there some specific reason for those files to be separate instead of inside the Matroska-container?
"

Easy-patching. I mentioned that in the SDHC article.
Also -- transparency to the end user.

I personally always place cover-images, cast-details, description of the title, all the various subtitles etc. inside Matroska-containers.


It's true that Matroska supports that, but it makes it more opaque to the end user.

Also, do you plan to support italics, bold and non-white text in subtitles?


Those are the advantages of the Kate ("OggKate") format that I originally specified. In fact, it can handle vector graphics as well.

However, SRT is a far more popular format, and you're the first person who's seen the benefit of the extra features in Kate that I have heard from (though admittedly, that has been a small sample so far).

Will give it further thought.

E.g. Raspberry Pi would hardware-wise be perfectly capable of doing that up to 1080p resolution as the SoC does support VP8-decoding, the only limiting factor is the drivers that do not at the moment have support for that.


Interesting claim. Can you back it up?

The queries I made before in tech forums led me to believe this was not a realistic expectation. In fact, it appeared that no VP8 hardware support existed in any SoC that could also handle the 1920x1080x30fps 12-24mbps video through-put.

However, I'd be very happy to see it work. A player based on a low-cost open hardware platform like RPi would be extremely attractive.

I suspect writing the support code for it is out of my depth, however. I would need to find someone capable of doing that.
