Iris on the Frame's kernel (6.18) offers HEVC Main 10 only into its compressed Q10C capture format. The component always asks for NV12, and a Main 10 stream in such a session returned no pictures: playback stayed at 0:00, the flush on leaving timed out (ACodec -110) and the next video hit MediaCodec::reclaim, so every later decoder start in the app failed until it restarted (seen in Bigscreen Beta with local files over DLNA). - hevc_profile.h reads general_profile_idc from the parameter sets (CODECCONFIG or the first access unit, Annex B or hvcC); streams beyond Main never open Iris and decode in FFmpeg's software HEVC decoder, which the component already contains. - Its 10-bit planar pictures are rounded to 8-bit planar before the existing outputs (no HDR tone mapping). - The HEVC component lists Main 10 (level 5.1), so format-aware players select it instead of reporting NoSupport and using it anyway. - Decoder revision 9; artifacts rebuilt with native/hevc/build.py (the same toolchain rebuilds revision 8 byte for byte). Tested on a Steam Frame in Bigscreen Beta: 1080p and 4K Main 10 clips and a real 1080p Main 10 episode play; 8-bit HEVC and H.264 afterwards play too. FFmpeg's software HEVC decoder on the Frame's CPU, 4 threads as the component uses: 1080p Main 10 episode 232 fps, synthetic 4K Main 10 72 fps.
