HEVC conformance fixtures

These fixtures come from the electronic attachment to ITU-T H.265.1 (10/2018), the conformance specification aligned with ISO/IEC 23008-8. Table 4 identifies the Sony GENERAL_*_RExt streams and their required profiles.

The .bit files are the original Annex B conformance streams. The Samsung archives name their payloads .bin; the repository stores those unchanged bytes with the common .bit extension. Each GENERAL_*_frame0.yuv file contains the first decoded picture extracted byte-for-byte from the corresponding published planar reference output; it was not generated by ImageSharp.

HevcPictureDecoderTests.DecodeOfficialRangeExtensionsPictureMatchesPublishedDigest limits each stream to its first independently coded picture, adapts that picture to the bounded hvc1 item contract, compares every reconstructed sample with _frame0.yuv, and verifies the published decoded-picture MD5 value for every present plane.

The retained matrix covers the ImageSharp 8, 10, and 12-bit still-image precision boundary across monochrome, 4:2:0, 4:2:2, and 4:4:4. The tool-specific matrix below completes independently coded coverage for the exposed Range Extensions profiles and tools. Explicit residual DPCM remains with dependent-picture inter decoding because the normative syntax requires an inter prediction unit.

The Main-profile traversal matrix comes from the official RQT_A_HHI_4 through RQT_E_HHI_4, STRUCT_A_Samsung_7, STRUCT_B_Samsung_7, and TUSIZE_A_Samsung_1 archives. Their published descriptions target residual-quadtree intra hierarchy depths zero through four, coding-tree and minimum-coding-unit structure, and a 64x64 coding-tree block with 32x32 minimum coding units and 16x16 minimum luma transforms, respectively.

HevcPictureDecoderTests.DecodeOfficialTraversalPictureMatchesPinnedHmDigest decodes each first independently coded picture through the production still-item path and compares all three native planes with fixed MD5 digests. The RQT values are the streams' decoded-picture-hash SEI values. For STRUCT and TUSIZE, the plane values were calculated from the first picture written by the HM reference decoder at commit 9c1f298659ab0cee9dc13d23d0304221575410b9; the complete HM output also matched each archive's published file MD5:

  • STRUCT_A_Samsung_7: 02f02cc9a67222004ae18ee6bebd475a
  • STRUCT_B_Samsung_7: 1f472e014aff120681e8482c8a04ef93
  • TUSIZE_A_Samsung_1: 5e6c198c852e92cdcca0e137fc2610c4

The intra-prediction fixtures come from the same official HEVC v1 attachment:

  • IPRED_B_Nokia_3 is the one-picture Main Still Picture stream identified by H.265.1 Table 1. Its published description states that it uses all 35 modes at each of the luma 32x32, 16x16, 8x8, and 4x4 sizes and the chroma 16x16, 8x8, and 4x4 sizes, for 245 mode-and-size combinations. The archive SHA-256 is 738E35AF4CED173E8CCB558464DC6A1B8B791FB1BB957C073633AA6037288CD0; the published bitstream MD5 is 1be12a94d9da6b84af78cd6cfd5e4407; and the retained published YUV has MD5 ec3bcad4f9174404e52d132206b6617b.
  • CIP_A_Panasonic_3 signals constrained intra prediction and contains one I picture followed by one B picture. The bounded still decoder test extracts only the independently coded I picture. The archive SHA-256 is 5C55B3594E5C951C9F5312913961750283EB2DADD15844FE35F9BEB94A9A548C, and the published bitstream MD5 is e1e00592fc8a158da9109b4dc05d03be.

HM at commit 9c1f298659ab0cee9dc13d23d0304221575410b9 reproduces the published IPRED_B_Nokia_3 YUV MD5 exactly and reports decoded-picture hashes 200ef9f7d2efde44ab872a78a40ece42, bfe9de3bef5ce5596a71bbfdbfb823fc, and 5b14acdd5c5bf8c6887160817ee1ad11. The same pinned decoder reproduces CIP_A_Panasonic_3's published complete two-picture YUV MD5 4cbf601ba98d63f642defab5eaa12c8d; its independently coded first picture reports plane hashes 69a20189e6bbb9c088e3adc967244ca1, 26502d354bb123f54c20413f14360ddb, and baafaef47a55ae2e876862b30b3bc720.

The residual-reconstruction fixtures come from the official HEVC v1 and Range Extensions attachments. Pinned HM commit 9c1f298659ab0cee9dc13d23d0304221575410b9 decodes every retained independently coded picture and produces the plane hashes asserted by the tests.

  • DELTAQP_A_BRCM_4_frame0.bit is the exact first independently coded picture extracted from DELTAQP_A_BRCM_4.bit. The official archive has SHA-256 63ABBBAF43D334D7952EAB7BBC5B3E34B4AD0259EDDCD63CDB164DBCF9A36CA6, the original bitstream has SHA-256 1274E3E308DFE684B38A88F8B3A2845B84F57492B0B02AAECBE5DC29CA8ED532, and the retained picture has SHA-256 4DC49A2AAE1CCE20D5CD190A1342FAF4C3B2BD06D1A59824542B9B22F53C581B. The official description randomizes diff_cu_qp_delta_depth from zero through three and delta QP from -26 through 25; the retained picture contains 384 delta-QP CABAC decisions.
  • QMATRIX_A_RExt_Sony_1.bit has SHA-256 74847E07F3298923DA0E9B68B1F861930D227BD5AD83A834A8280CF042A7E78F. Its official description covers scaling-list data with and without transform skip at every transform size over different QPs; the retained first picture signals scaling lists, coding-unit QP deltas, transform skip, transform-skip contexts and rotation, and implicit residual DPCM.
  • EXTPREC_MAIN_444_16_INTRA_12BIT_RExt_Sony_1.bit is the second of the official stream's two concatenated one-picture sequences, retained with its own VPS, SPS, and PPS. The official archive has SHA-256 66C8E24866210B94A63A29C93F8C1490046CC17B26484C5BD81F805D7BFD18D1, the original bitstream has SHA-256 5F0164DCCC333296FB2753068CAFE4985B758DDB7E282358DBB8FAF74986817D, and the retained sequence has SHA-256 4107D5BB5DF4F95185E7A8A5EEF8F35970A4769C76901FF590F38F7BC36B268B. This 12-bit GBR sequence is the one that signals extended-precision processing and transform skip. Its reference plane hashes were produced by the pinned HM commit built with its HIGH_BITDEPTH option, which is required by HM for this sequence.
  • GENERAL_12b_444_RExt_Sony_2_idr7.bit is the seventh independently coded picture extracted with its active VPS, SPS, and PPS from the already retained official GENERAL stream. It has SHA-256 981D97F0ADC228F2E3A739D7A68161F84CD60309745397D5CF24D2F81C009DBC and contains 39 coding-unit chroma-QP adjustment decisions across 8-, 16-, and 32-sample chroma transforms.
  • LS_A_Orange_2.bit has SHA-256 14251238F005A4576437429A327B34D216B346AAAC2A7A05C132A3430174B11B and published MD5 9118d01cf6b3671038d6f99342c0895e. The official lossless description states that every coding unit uses transform, quantization, and filtering bypass; the retained first picture exercises the bypass-flag path and its decoded-picture hash reports OK.

The remaining Range Extensions fixtures come from the official H.265.1 RExt attachment. Each retained file contains the active VPS, SPS, and PPS followed by exactly one independently coded picture. For the extended-precision streams, the retained picture is the second concatenated one-picture sequence because that sequence enables extended-precision processing. HevcPictureDecoderTests.DecodeOfficialRangeExtensionProfilePictureMatchesDecodedPictureHash checks profile identifier, luma and chroma precision, chroma layout, required tool flags, and every native-plane MD5 through the production still-item decoder.

The expected plane hashes come directly from each selected picture's decoded-picture-hash SEI message when present. The CCP 8/10/12-bit, IPCM A/B, and Main 4:2:2 10 B streams omit that per-picture message. Their first reference pictures were extracted only after FFmpeg 9.0.1 reproduced the archives' published complete-output MD5 values 54231c6f121ca65d8b94a747b9504b8b, 363f55fc6097a3bb7525392b87a6498a, f3e914fccdb820eac85f46642ea0e168, 8d4eb18812338f9f475035b8da27e74a, eea32e6e1f88b7782515e53f8122be7d, and fd163bcbdc24792a23781ee7aace74eb, respectively.

Genuine HEIC presentation matrix

The 35 .heic files pair every retained official Range Extensions picture above with a real ISO BMFF image item. GPAC MP4Box 26.07 (26.07-rev0-ga07cbfff-master) wrote the containers. FFmpeg 9.0.1 first copied one complete picture, including its active VPS, SPS, and PPS, from each supported Annex B stream so the hvcC configuration and item payload cannot select parameter sets from different concatenated pictures. The two unequal-precision streams are already bounded pictures and were passed directly to GPAC because FFmpeg rejects unequal luma and chroma precision.

The generation templates were:

The monochrome files add image-pixi=8 or image-pixi=12 to the -add-image argument so their pixi property contains exactly one channel. No colr property is added; the decoder must retain the HEVC VUI color description.

Twenty-four *-ffmpeg.png files are FFmpeg 9.0.1 presentations decoded directly from the resulting HEIC files. Nine *-hm-ffmpeg.png files use native samples from pinned HM commit 9c1f298659ab0cee9dc13d23d0304221575410b9, built with HIGH_BITDEPTH=ON, followed by FFmpeg raw-video color conversion. Every HM plane used by those references matches the official decoded-picture-hash values. This split is intentional: FFmpeg does not reconstruct seven of the retained high-throughput pictures to their published plane digests, and its direct monochrome-to-PNG path does not expand the signaled limited luma range. The monochrome references therefore apply the exact 8- or 12-bit limited-range scale before RGB packing.

The two unequal-precision HEIC files have no PNG reference because FFmpeg and libheif reject that HEVC profile combination. Their public tests require successful bounded HEIC presentation and correct metadata, while the companion native tests compare all three planes with the published digests.

HeifDecoderTests covers all 35 genuine HEIC files. The 33 independently presentable cases use the repository's narrow TolerantPercentage(1F, 20) public-pixel contract because HEVC does not prescribe one chroma upsampling filter. Exact native-plane tests remain the reconstruction oracle. Representative 8/10/12-bit, monochrome, 4:2:0, 4:2:2, 4:4:4, and high-throughput files also pass with 4 KiB allocator groups and exactly-once returns. Eight-bit subsampled and 12-bit full-resolution presentation repeat through AVX-512, AVX, narrower vector, and scalar FeatureTestRunner configurations.

PRESENTATION_SHA256.md records every retained HEIC and PNG SHA-256.

The retained ENTP_A_Qualcomm_1 first picture verifies its uniform 2x2 tile entry points. The archive description places its special entry-point emulation-prevention case at POC 4, which is outside the retained IDR picture. HevcPictureDecoderTests.EntryPointOffsetsExcludeEmulationPreventionBytes therefore verifies the same production boundary-conversion methods directly with prevention bytes in both the encoded header and the bounded non-final entropy substream; it does not claim that the later non-IDR picture itself is decoded.
