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. Libav's DV encoder tracks AC bit + component is greater than 36. FFmpeg'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 @@ -509,7 +509,7 @@ 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 Libav method */ +#else /* improved FFmpeg method */ static const int classes[] = {-1, -1, 255, 0xffff}; #endif int max = classes[0]; @@ -952,10 +952,8 @@ static int dvvideo_encode_frame(AVCodecContext *c, AVPacket *pkt, s->sys = avpriv_dv_codec_profile(c); if (!s->sys || ff_dv_init_dynamic_tables(s->sys)) return -1; - if ((ret = ff_alloc_packet(pkt, s->sys->frame_size)) < 0) { - av_log(c, AV_LOG_ERROR, "Error getting output packet.\n"); + if ((ret = ff_alloc_packet2(c, pkt, s->sys->frame_size)) < 0) return ret; - } c->pix_fmt = s->sys->pix_fmt; s->picture = *frame; |
