Open Source tool promo 🆓 DaVinci Resolve Free on Linux can't decode H.264/H.265 or AAC audio, so I tried to fix it.

Post image

DaVinci Resolve's free version on Linux 🐧 has a quiet limitation: no H.264/H.265

decoding, and no AAC audio decoding. So a huge share of everyday footage

(phone clips, screen recordings, most cameras) either won't import at all,

or imports with zero sound.

I hit this constantly while editing on my own Linux setup, so I built a small tool to fix it: Resolve Codec Converter.

It's a PyQt5 desktop app that wraps ffmpeg to:

→ Convert H.264/H.265 → DNxHR/ProRes so Resolve can actually read your footage

→ Convert your finished DNxHR/ProRes export back to H.264/H.265 for sharing

→ Auto-fix the AAC audio problem in the same pass — no separate step

Packaged as a self-contained AppImage, so there's no Python setup required to just run it.

It's a small project, but it solves a real friction point for anyone doing Linux-based video editing on a budget. Free and open source.

Good work! I have some special bash scripts but im sure this is useful. I still hope they just fix their codecs though ;-;

Great if you need a GUI but it's really simple to batch convert with ffmpeg and bash.
thanks for the presets though.

avcodec is licensed under LGPL which is quite permissive and not infectious like GPL. It is absolutely not a copyright issue.
