Test H.264/AVC video decoders compliance
Allegro DVT compliance bitstreams are designed for intensive testing of H.264/AVC|MVC|SVC decoder implementations.
Given the higher complexity of H.264/AVC compared to MPEG-2, such testing is an absolute necessity before mass deployment.
Allegro DVT provides several test suites. Each test suite targets a specific profile/level combination.
Type | Resolution |
H.264 Baseline profile – Level 1.3 T-DMB | 176×144@30fps |
H.264 Baseline profile – Level 2 | 352×288@30fps |
H.264 Baseline profile – Level 3 | 720×576@25fps 720×480@30fps |
H.264 Baseline profile – Level 3.1 | 1280×720@30fps 1280×720@25fps |
H.264 Main profile – Level 3 | 720×576@25fps 720×480@30fps |

Allegro DVT has developed its own H.264 encoder dedicated to generating test bitstreams. This encoder is designed for high configurability rather than maximum compression ratio. All encoding parameters (picture type, slice type, loop filter parameters, slice reordering, MMCO, macroblock type, quantization parameter, motion vector, prediction direction, intra prediction direction, constrained intra prediction, direct mode type, etc.) can be controlled at macroblock granularity.
Using this dedicated encoder, Allegro DVT has generated:
