| Summary | 0000285: Cannot encode or decode 4:4:4 MBAFF (CABAC) streams | ||||
| Description | Trying to encode 4:4:4 8/14-bit interlaced planar YUV data results in a segmentation fault: encodes if MBInterlace is 0 or 3, but not 1 or 2. 4:4:4 MBAFF bitstream encoded with x264 successfully playbacks, but decoders 17.2, 18.1 and 18.2 fail to decode; error messages of the form: warning: Intra_8x8_Horizontal_Down prediction mode not allowed at mb 630 warning: Intra_4x4_Horizontal_Up prediction mode not allowed at mb 721 RefPicList0[ num_ref_idx_l0_active_minus1 ] is equal to 'no reference picture', invalid bitstream 17.2 produces similar messages but at earlier MBs. | ||||
| Steps To Reproduce | For encoding: ./lencod.exe -p InputFile=<insert 4:4:4 planar YUV> -p InputHeaderLength=0 -p FrameRate=25.0 -p OutputFile=<...> -p YUVFormat=3 -p ProfileIDC=244 ( -p EnableIPCM=2 ) -p SymbolMode=1 -p PicInterlace=2 -p MBInterlace=2 -p ReferenceReorder=0 -p PocMemoryManagement=0 For decoding: Use attached file - no parameters specified. | ||||
