4-Codec Extended Test Sets

AV1 · H.264 · H.265 · VP9 streams for hardware decoder testing

1773 streams · 1773 verified with reference decoders · 13.8 GB

Every stream has 60 frames = 2 GOPs of 30 (keyframes at frames 0 and 30) and was decoded with the codec's reference decoder (aomdec, JM, HM, vpxdec); the YUV md5 is in the stream's .json and was cross-checked with ffmpeg for AVC/HEVC/VP9. Level and buffer in each file name follow the codec's level tables and the actual bitrate. Sources: AOM CTC sequences plus the Fraunhofer HHI 8K clip. Thumbnails show the first decoded frame, scaled to 512 px (HDR PQ content is shown without tone mapping, so it looks flat).

Robustness

ERR · error resilience

Clean AV1 / VP9 / AVC / HEVC streams (5K 2x2 tiles, 1100-frame 480p, VP9 also with resolution changes) with lists of 8500 single-error cases (bit flips, bursts, truncation, dropped units) split into header and payload, reference-decoder outcomes and the first damaged symbol.

UNS · unsupported streams

41 valid streams that each break exactly one limit of the target VPU (level 6.2, > 8192, 12-bit, 4:2:2 / 4:4:4, interlace, FMO / ASO, too many tiles or slices) - the decoder must reject them cleanly.
