Snacks v2.0.1

Automated Video Library Encoder

Patch release focused on 4K encoding reliability, queue usability, and Docker deployment fixes.

What's New

4K VAAPI calibration overhaul -- starting QP raised from 24 to 30 for 4K content, test duration doubled to 60 seconds, sample point moved to 40% into the file (avoids intros), and max calibration iterations increased from 3 to 6 so quality convergence actually reaches the target bitrate
Stall detection timeout increased to 5 minutes -- the previous 30-second timeout was killing FFmpeg during the final muxing phase (moov atom relocation for MP4, MKV finalization) on large 4K files and slow NAS drives, causing failures at 99% progress
Bitrate tolerance loosened to 20% -- VAAPI CQP calibration now accepts output within 20% of target (was 15%), reducing unnecessary re-calibration passes

Queue filter tabs -- filter the queue by All, Pending, Completed, or Failed with count badges on each tab
First/last page navigation -- pagination now includes double-chevron buttons to jump directly to the first or last page
Fixed "Now Processing" flickering -- the processing indicator no longer disappears and reappears when viewing non-first pages of the queue
Fixed first page showing fewer items -- processing items are now excluded from pagination so every page shows the full 5 items
Removed refresh button -- the queue auto-refreshes via SignalR so the manual refresh button was unnecessary

Fixed Docker Desktop startup failure -- GPU passthrough settings (/dev/dri, video/render groups) moved to a separate docker-compose.gpu.yml overlay so the base compose works on Windows and Mac without errors
Fixed port mismatch -- base docker-compose.yml and Dockerfile now consistently use port 6767 (was incorrectly set to 8080 in some places)
Dual Docker Hub push -- build-and-export.bat now pushes to both derekshreds/snacks-docker:latest and derekshreds/snacksweb:latest so users on the old image name receive updates
Backend status filtering -- GetWorkItems endpoint accepts an optional ?status= parameter for server-side filtering

docker pull derekshreds/snacks-docker:latest

On Linux hosts with GPU acceleration, use the GPU overlay:

docker-compose -f docker-compose.yml -f docker-compose.gpu.yml up -d

start-snacksweb.bat

Uses the base compose only -- no GPU passthrough needed.

Download the installer from the Releases page, or build from source:
