help compiling Opus! i'm stuck at opusfile. configure says i don't have openssl package installed but Debian 9.4 thinks i do. this Debian only have Opus 1.2-alpha2 package, so i need to compile Opus by myself. seems even Debian developers having trouble compiling latest versions of Opus, what chances do i have to succeed? -------------- next part -------------- An HTML attachment was

Hello. Me again. Have you tried to encode piano solo? Noticed high bitrate Opus gave? And there's also artefact at 15kHz which wasn't in the original audio. Visible with Spek program. Download FLAC and Opus both files, new link: http://www.filedropper.com/example_3 FLAC full: 1084 kbps; FLAC solo: 465 kbps. with --bitrate 160: Opus full: 158 kbps; Opus solo: 190 kbps. Included also Spek

Hello! Trying to compile, build, install and run Opus. My config: Ubuntu console (Windows 10 app). First problem, configure says openssl is missing. My system says that i have openssl already. Which openssl does it need? Using aptitude, i've installed everything with openssl name in it. That's tons of files and gigabytes of data. But it worked somehow. Second problem, flac-1.3.2 -

tracked down the spectogram atrefact source; it comes from the resampler. so it's not really a bug, just a nuisance. let's hope in the future Opus will be able to save bitrate on simple audio parts as all other lossy and lossless codecs do. i think opus decreasing bitrate only when it thinks that audio is too complex for human to hear difference. that's a bad attitude.

Opus is specifically designed to survive tandeming but you need to keep the frames aligned and not mess with the gain, which your tools probably do not do.

It appears that both Opus and amrnb have a function called preemphasis(). In the short term, your options are: 1) Not building statically 2) Renaming that function in the Opus code 3) Renaming that function in the amrnb code I can do the rename for the next version of libopus.

Hi, Seems like it's not linking with libm. I suspect it has to do with linking statically with libopus.a (is that intended?). Maybe opus-tools relies on the fact that libopus is linked with libm and doesn't explicitly add it? Greg?

Linking statically requires -lm, but there's no way for opus-tools to know you've done this and pass --static to pkg-config along with --libs. Did you pass --disable-shared when building on the other Ubuntu systems where the

Hi, I am trying to compile the opus-1.0.2 source code for ios. When I import the files in Xcode and try to build, the build fails. How can we successfully compile opus using Xcode? Are there any special configurations? Thanks a lot in advance! -------------- next part -------------- An HTML attachment was scrubbed... URL:
