New decoders for MP3 and AC-3

Development recently finished on decoders for two more formats, MP3 and AC-3. The MP3 decoder (ewmp3dec) will be added to the retail decoder package soon, and will be available as an update for people that purchased the decoder pack previously. We’re still working on the patent licensing for AC-3, so it won’t be part of the retail decoder pack just yet. However, both codecs are available to OEMs as a software license.

GStreamer Conference Recap

The first GStreamer conference took place last week in Cambridge in the UK, which I attended and gave a presentation about Orc.  I was pleasantly surprised at the number of people that attended, packing the room with people spilling out into the hall.  For those of you that missed it, the presentation was recorded by the people from Free Electrons and will be posted on their site some time soon.

Several people mentioned to me at the conference some variation of “I have no assembly background, but I learned how to use Orc in a few hours, converted my video processing code, and now it’s 4x faster.”  This is always encouraging to hear.  Of course, some mention that Orc-generated code isn’t faster than C code — we’ll have to work on that.

The rest of the GStreamer conference was excellent and a huge success.  The organizer, Christian Schaller, said that the conference was sold out, so it seems likely that we’ll have a bigger and better conference next year.  I was interested in seeing every talk, which means I’ll be spending an entire day watching the ones I missed whenever the video is uploaded.

Open Video Conference Recap

It’s taken me a week to recover from our week in New York for Open Video Conference and FOMS, but it was so worth it. We had a great time meeting with old friends, some of whom we only see online or once a year at conventions, as well as networking with a ton of terrific new people.

Huge appreciation goes to Ben Moskowitz for organizing an inspiring and well run conference. We were happy to help sponsor Open Video Conference, and look forward to returning. This year the conference was bigger, more diverse, and reflected the evolving world of open video to not only software developers, but end users, film makers, and non-profit groups. It’s an exciting time to be working in this kind of technology.

The first day we ran demos of the Entropy Wave E1000 Live Encoder, streaming up to HD quality video from the E1000 to several devices to show the versatility of the box.

Here’s one of the streams (HD Ogg/Theora/Vorbis over RTP) on a Linux-based laptop

Another of the streams (Ogg/Theora/Vorbis) being played on a stock Nokia N900.

And a third stream (MPEG-TS/H.264/AAC) being played on an Apple iPhone demonstrating H.264, AAC, MPG-TS, and Apple HTTP Live Streaming.

The next day David Schleef moderated a panel discussion on Licensing, Patent Issues, and Standardization of codecs, participants included Laura DeNardis (Executive Director at Yale Isp), Mike Flathers (CTO Sorenson Media), Rob Glidden (Open Video/Digital TV standards advocate), and Timothy Terriberry (codec developer currently with Mozilla). Among the five of them, they represented enough knowledge on the legal and logistical side of open codecs that an entire conference could have been filled with just that discussion. Unfortunately, they only had an hour, but a ton of useful knowledge was shared and an extremely lively discussion ensued.

After that, we ran to David’s next talk, discussing video compression trade-offs, geared towards end users like editors and workflow managers. Again, with only an hour it’s impossible to really cover most of the issues involved, but he and Jon Dahl of Zencoder gave a very decent overview of the encoder options, and in Jon’s case, a discussion of cloud encoding.

The next day was the start of Foundations of Open Media Software, which was well organized and kept on task by Silvia Pfeiffer. In the two days of discussion, a ton was covered. Check out the write-up of day one, general discussion about the advantages and disadvantages of adaptive HTTP streaming, and day two, discussing the creation of a solution for Ogg and WebM.  Sylvia has a great write up on her blog about some of this as well.

We actually did manage to get out and enjoy a bit of the city after the conferences. David and I took in the Metropolitan Museum with some fellow developers, it was nice to get out from behind the laptops and the Met is astounding!

Entropy Wave at Open Video Conference

Entropy Wave is proud to be one of the sponsors of this years Open Video Conference in New York, October 1-2.

The conference is a great mixture of people from both sides of open video: open content and open technology.  Our founder, David Schleef, will be giving a talk alongside Jon Dahl of Zencoder that ties the two sides together, explaining to content producers how to use the technology to its fullest, check that out at noon on Oct 2.

On Friday we’ll be demoing our E1000 hardware box, which does live video encoding and streaming using open video technology, available as an end-user product.

Along with OVC, we’ll be participating at the Foundations of Open Media developer workshop.
