[FFmpeg-devel] [PATCH v3 1/3] avcodec/vvc_parser: move avctx->has_b_frames initialization to dec

[toqsxw at outlook.com]

From: Wu Jianhua <toqsxw at outlook.com>

>From Jun Zhao <mypopydev at gmail.com>:
> Should we relocate this to the decoder? Other codecs typically set this
> parameter in the decoder.
