RealNetworks Releases Helix Source

teeheehee writes "According to this DigitalMass article, RealNetworks yesterday released source code for their audio and video players, with server-side and encoding software coming maybe in December. The code isn't complete, it's missing things like burning-to-cd routines; and they're getting flak from Microsoft calling it a ploy. Regardless, anytime a big company releases their source only good can come of it (for the public.)" Our story a few days ago had more information on the licensing, and gathered a couple of interesting posts from one user.

Re:How open is this source?

[lewp]

First off, the CD burning routines aren't that important. There is plenty of Open Source code out there that can burn a decent CD. The media playing bits are the important and interesting part.

Real appears to have two licenses available for use. One caters to the Open Source community and one seems to cater to businesses that aren't as keen on OSS.

Under the RPSL (the license intended for the OSS community) code based on the Helix source needs to itself be released under the RPSL, but it can also be dual licensed with a great deal of Open Source licenses including, among others, the BSD license, the (L)GPL, and Apple's source license. The full list can be found here:

It looks like they've got a really good start here for being a good citizen in the OSS community while not alienating potential customers who aren't comfortable with the concept yet. I still need to read the RPSL thoroughly, but it'll be interesting to see what happens with this.

gratis, not libre

According to the Salon article someone already linked, the Helix license doesn't fulfill the Free Software or Open Source definitions. Royalty-free redistribution is only permitted noncommercially. Also, according to another post, most of the Realplayer codecs--the only parts of Realplayer that are interesting at all--are still closed.

RealVideo 9 is an extremely inefficient codec

I'll skip past most of your whining, and focus on something you're just straight-up technically wrong about.

The RealVideo 9 codec has the best compression effciency (bang for the bit) of any publically available codec in a GM version (I'm discounting Windows Media Video 9, since it is still in beta, but that would be somewhat better in some cases).

Sure, it rarely looks perfect, but it does better than other codecs.

Bear in mind that going from uncompressed video to modem data rates is about a 12000:1 compression! Folks used to watching DivX don't often realize that those files use data rates several times that of typical real-time streaming even over broadband. Also, a file download can have huge data rate spikes that aren't as possible under real-time streaming.
