Nice, I'm looking forward to seeing how this performs in practice. FFmpeg's previous AAC encoder produced poor quality output and often had irritating chirping artifacts, so I've always had to install Apple's Core Audio encoder on any computer I do video recording on to get decent sound. I've done A/B/X comparisons and found that a 320kbps MP3 sounds better than a 320kbps AAC encoded by FFmpeg, but about the same as…

A useful project related to Apple's Core Audio is qaac - it wraps iTunes Windows DLL's in a standalone encoding tool with a CLI interface. I believe it even works under Wine on Linux: https://web.archive.org/web/20250814194428/https://www.andre... So you don't need a Mac or even a full iTunes installation to get high quality AAC encoding.

Well tyvm, I found a new tweak for my transcoding pipeline :)

Earlier quoted context omitted.

They have hardware decoders for JPEG? I have never heard of this and it seems overkill considering how simple it is to decode.

Seems like Nvidia doesn’t support JPEG in NVDEC.
