FLAC plug-in for Adobe Premiere
Hey everyone, I've written a FLAC plug-ing for Adobe Premiere. It's actually part of the Ogg Vorbis plug-in I originally set out to write. You can see it here on GitHub: https://github.com/fnordware/AdobeOgg I just finished the first beta a few hours ago. You can download binary plug-ins from here: http://www.fnordware.com/downloads/Ogg_v0.5b1_mac.zip http://www.fnordware.com/downloads/Ogg_v0.5b1_win.zip If you don't have Premiere, you can always download the 30-trial.

Opus in WebM
What got me experimenting with Opus is that I heard it's going to be a supported codec in WebM, which I also have a Premiere plug-in for: http://github.com/fnordware/AdobeWebM I just posted a new beta that includes Opus support. Naturally, I *think* I'm doing it right, but I'd love for someone more knowledgeable about Opus or WebM to take a look. The closest thing to a standards document for putting Opus into WebM is here: http://wiki.xiph.org/Mat...

Meaning of mapping[]
Hey everyone, I've added Ogg Opus support to my Adobe Premiere plug-in here: http://github.com/fnordware/AdobeOgg Now I'll add Opus support to me WebM plug-in too. I've got this Opus stuff mostly figured out, but I have a few questions. Here's one: What do the numbers in mapping mean? I see that opus.h refers to the Vorbis channel mapping order, so does mapping in Opus take that ord...

Opus in WebM
Yes, it's basically an intrinsic aspect of the mathematics. If you seek into the middle of an Opus stream, that's about how long it takes before the audio converges to be correct.

...s from scratch and importing the FLAC source right into my project and I get the same errors. If someone would be so kind as to take a look, I have a branch set up, ready to show you the problem (after you download the Premiere SDK). I've posted this as a GitHub issue here: http://github.com/fnordware/AdobeOgg/issues/4 Help me, Obi-Wan Kanobi! Brendan

Opus in WebM
...the frame data. When you combine a starting frame with the subsequent frame, the data you get back is from the starting timestamp forward. Because Opus needs to preroll a larger amount, that trick wouldn't work with Opus.

Seeking in WebM
Hi everyone, I'm working on a WebM plug-in for Premiere. You probably already know that WebM is a Matroska container that uses Vorbis for audio compression. I'm pretty new to the world of audio compression and need some help. You can see my code here: http://github.com/fnordware/AdobeWebM First of all, I wonder if it's possible to seek to an exact audio sample in WebM. Whereas an Ogg page provides you with the granule position, Matroska provides a much less precise timecode, measured in milliseconds. So the second frame at time 41.6666ms gets rounded to 42ms in Mat...

Converting audio samples
Hey everyone, I'm new to the world of audio, so can you please drop some very basic audio knowledge on me? What's the correct way to convert from float audio samples to integer ones like FLAC uses? If I'm converting to 8-bit, that has a range of -128 to 127, right? Do I multiply my float input by 127 or 128? Brendan

Unfortunately, I don't think that's it. Visual Studio gives me a specific error when it can't find a certain library file. I think these are the errors you get when a

Possible bug in opus_multistream_surround_encoder_create()
I get reliable crashes if I create a 6-channel encoder using opus_multistream_surround_encoder_create(). If I use opus_multistream_encoder_create() instead and pass in the same parameters that opus_multistream_surround_encoder_create() sends out (streams = 4, coupled_streams = 2, mapping = {0, 4, 1, 2, 3, 5}) I don't get the crashes. I notice that opus_demo.c uses

If you seek into the middle of an Opus stream, that's about how long it takes before the audio converges to be correct. I see. Thanks for the info. Any idea about the other Matroska tags? I guess CodecDelay will be the value you get from OPUS_GET_LOOKAHEAD()
