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! 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 -

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

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.

1) thanks, i've installed libssl1.0-dev and compling process continued. 2) compiled opus passing --disable-shared to configure b/c shared cannot find library (i'm new to Linux) 3) compiled opus 1.3-beta-40 successfully! it is faster than 32 bit Windows version! -------------- next part -------------- An HTML attachment was scrubbed...

Hello. i have over 30GB of Opus music and noticed that solo instrumentals and solo vocals uses more bitrate than full-mixes. Here's example where Opus 1.3 used 190 kbps for piano solo and 159 kbps for full-mix. (--bitrate 160 --music) Download example piano solo 15MB: https://mega.nz/#!wLBz3AZT!YmqQMkAGqc4kGHumNWZAfB7Cmcf4vFlHpT6IiiAVCNA FLAC uses 2 times less bitrate for solo than full-mix
