The SMPTE method is very conservative; it assigns class 3 (i.e. severe quantization) to any block where the largest AC - component is greater than 36. FFmpeg's DV encoder tracks AC bit + component is greater than 36. Libav's DV encoder tracks AC bit consumption precisely, so there is no need to bias most blocks towards strongly lossy compression. Instead, we assign class 2 to most blocks, and use class 3 only when strictly necessary @@ -795,7 +795,7 @@ static av_always_inline int dv_init_enc_block(EncBlockInfo* bi, uint8_t *data, i #if 0 /* SMPTE spec method */ static const int classes[] = {12, 24, 36, 0xffff}; -#else /* improved FFmpeg method */ +#else /* improved Libav method */ static const int classes[] = {-1, -1, 255, 0xffff}; #endif int max = classes[0]; |
