David, Here's the trick ... do this just before your speex_bits_write(): speex_bits_insert_terminator(&bits); Then, when decoding, keep calling speex_decode() until it returns -1 or speex_bits_remaining(&bits) returns 0. Works for me, anyway. Tom David Barrett (dbarrett@quinthar.com) wrote: > > Hi, I'm using Speex and I want to pack multiple frames into a single > packet.

...0); I am using a newer version of Speex, so I guess the terminator is a relatively new thing. I'm not even sure if it's necessary, but I think Jean-Marc recommended using it back when I asked this question awhile ago..? Anyway, glad it's working for you.

I apologize for what's surely a common question, but the Xiph archive-searcher seems broken, and all my other searches have come up dry. Anyway, my question is: Are there any Theora binaries available for Visual Studio.NET? Alternatively, how do I build Theora using Visual Studio.NET? I tried using "\win32\theora_static.dsp", but VS.NET claimed it was corrupt and couldn't

What's the easiest way to broadcast a "live" event using Theora? - Microsoft Media Services uses a closed protocol (MMS) and special streaming servers, so I'm not excited to go that way, even though it seems to be the most obvious choice. (Though I'm not sure if I could convince it to use Theora anyway.) - I could encode the entire file into an Ogg/Theora file and just

I decided to bite the bullet and grabbed the latest changes out of subversion. Compiled fine (with a few cast changes), but for some reason none of the encoding functions are linking. (Decoding appears to link just fine.) Any ideas what I did wrong? Here's what I did: 1) Downloaded a clean copy of the latest contents of Subversion using: svn co http://svn.xiph.org/trunk/theora 2)

The roadmap page on the website is a bit terse. Any ideas when the next release (stable or otherwise) might be coming out? -david -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/speex-dev/attachments/20041009/85ff6ded/attachment.htm

Today marks the one-year anniversary of iGlance, my P2P voice, video, and realtime-collaboration application. In honor of the event, I'm opening my doors to a select group of alpha-users who will: - Help test the boring stuff - Help refine and design the good stuff - Help decide what iGlance is all about As you know, this is a crowded space.

So you all know I've been working with Speex on iGlance for ages. Well, I'm happy to report that after all this time, it's done. (Well, as much as anything in this space is ever done, but it works for some large subset of users, and it has a snazzy website to promote it.)

I'm sure this is a common question, but I haven't seen it asked nor answered on this list, on the Theora Wiki nor FAQ, nor on the Internet at large (though I haven't checked the whole thing): Has anyone ported 'libtheora' to WinCE or PocketPC 2003? I seem to recall seeing a Linux ARM port, but I haven't been able to confirm that, either. I see there's a

Can anyone recommend a good library for performing audio downsampling? I intend to start playing around with "libresample" (http://ccrma-www.stanford.edu/~jos/resample/README-libresample-0.1.3.txt), as well as taking a look at "Secret Rabbit Code" (http://www.mega-nerd.com/SRC/), but I'd love some opinions before I get too involved with either. Free would be best, but

What is the best way to pick a prebuffering length for a streaming audio application using UDP transport? I'm using Speex in a VoIP application with RTP transport, currently with a fixed 500ms prebuffer on the playback side. However, I'd like something a bit more adaptive to accomodate high-jitter connections. For example, in one test configuration there is a very low average

Ah, I'm sorry, I have read the manual and believe I have a reasonably good grasp on how to use the Speex encoder and decoder altogether. In fact I've been using it with great success in my P2P SIP/RTP VoIP application for almost a year now; it's been working wonderfully and I can't thank you enough. However, the manual makes no mention of the jitter buffer, nor does it (so

Ok, this is a silly question, but what does the jitter buffer do? I'm really new to audio, so please bear with me. From what I gather (primarily from the list archive), the jitter buffer is a wrapper around the Speex decoder. I give it the packets I receive, in whatever order I receive them, and then it gives me back a clean stream of audio samples. But what I don't entirely
