Reference plex browser 10bit hevc choppy

Choppy Plex playback in a browser (Plex Web / Chrome) on a 10-bit HEVC source is a client codec-support mismatch, not a server bug or bad rip.

Diagnosed 2026-06-28 on Vector (Windows PC, IP 192.168.86.67). Show: Devious Maids, entire series is x265-INFINITY rips: HEVC Main 10 / yuv420p10le (10-bit), ~2 Mbps 1080p, AAC 5.1, MP4.

Tautulli get_stream_data for the Chrome session showed video_decision=copy (10-bit HEVC passed through), audio_decision=transcode (5.1->stereo), container=transcode. paused_counter 28 and 240 = constant decode stalls. Bandwidth was never the issue (2 Mbps); the browser MSE path cannot HW-decode 10-bit HEVC and does not use the RTX 5070.

Corroboration: same files direct-play smoothly on the Google TV Streamer (Android, paused_counter ~0, native 10-bit HEVC decode). Roku transcodes.

Fix (root cause): use the Plex Desktop / HTPC app on Vector instead of the browser. Native 10-bit HEVC decode on the 5070, direct-play, zero server load, no quality loss. Fallback: set Plex Web Quality to a fixed bitrate to force a server H.264 transcode.

Not related to [[reference_plex_audio_compat]], [[reference_plex_h264_vaapi_segment_muxer_bug]], or [[reference_plex_gpu_xe_driver]]; those are separate Plex issues.

Status 2026-06-28: diagnosed; Justin chose to wait, no change applied.
