❓Question💻Web🗄️Server☑️Ready
Environment:
- Immich v2.4.1
- Kubernetes deployment
- Intel GPU (QSV/VAAPI via DRA)
- Browser: Vivaldi (Chromium-based) on Fedora KDE
Issue:
Playing a video via web UI shows first frame frozen while audio plays normally. Tested via public share link.
Source video:
- iPhone recording (
- HEVC Main 10 (10-bit HDR)
- AAC audio
Transcoded video:
What I've tried:
1. QSV acceleration → same issue
2. VAAPI acceleration → same issue
3. Changed preset from
4. Verified transcoded file is served correctly (API returns
5. Confirmed moov atom is at file start (faststart)
Transcoding settings:
- Target codec: H.264
- Target resolution: 720p
- Tone-mapping: Hable
- Hardware decoding: enabled
Suspicion:
Both QSV and VAAPI produce
Questions:
1. Is there a way to force
2. Is this a known issue with HDR→SDR tone-mapping + hardware encoding?
3. Any other settings to try before falling back to software encoding?
